Some studies have shown that proline accumulation is generally an indicator of leaf dehydration and is associated with stress susceptibility (Hanson et al., 1977). ( 2012) also observed a The crown root phenotyping technique is one of the promising technologies for 2D image collection under various field conditions [163]. Tripathy J., Zhang J., Robin S., Nguyen T.T., Nguyen H. QTLs for cell-membrane stability mapped in rice (Oryza sativa L.) under drought stress. Proceedings of International Workshop (Vientiane, Laos), pp 6977, Pantuwan G, Fukai S, Cooper M, Rajatasereekul S, OToole JC. The .gov means its official. Although the root length and surface area may determine the uptake of soil resources [52], young root tips are the main regions of water uptake [53]. Seeds were sown in a wet seedbed and transplanted to puddled lowland fields at 1718days after sowing. Rice root characterization is often performed in containers in greenhouses and fields, which is labor- and time-intensive. Centrifuged and decanted the supernatants to the 50-mL volumetric flask, and repeated the extraction with 4.6N HClO4 one more time. ISSR assay also proved the considerable mutational effect of EMS on two mutant lines compared with the original wild line. On the other hand, the higher number of open spikelets in IR 87707445-B-B-B even at the late heading period of WS2014 and DS2015 (Table 1) supports its drought tolerance inherited by drought tolerant QTLs (qDTY2.2 +qDTY4.1; Swamy et al., 2013). Values are the mean standard deviation (n=35 plots). In the future, multiple root characteristics should be improved, such as water use efficiency and nutrient acquisition [184]. In water-stress assays, we found that water deficit as expected negatively imposed all evaluated morpho-physiological characters of rice plant, but the severity of loosed performance differed depending on stress level and genotype. MAMBANI B., Lal R. Response of upland rice varieties to drought stress: I. Fageria N.K., Moreira A. An automated, cost-effective and scalable, flood-and-drain based root phenotyping system for cereals. 2014). For studying root traits associated with drought, selected germplasms comprise those with relatively thicker root systems, thicker root systems, early maturity, and the capacity to produce new tillers after re-wetting [136]. For this reason, here, we will briefly describe 2D image-based phenotyping methods for field experiments. The optimal partitioning theory proposes that a plant distributes the resources among its various organs for optimal growth [37]. In this research, we analyzed the molecular differences of an original line (Neda) and two mutant lines developed after mutagenesis of Neda line using EMS chemical mutagen. Severe drought significantly decreased starch content in leaves and sheaths of varieties, except for DA8 and Kinandang Patong in 2015 (Figure 7). The number of open spikelets was greatest in IR 87707445-B-B-B (20.7), followed by IR64 (15.6) and IR64+qEMF3 (7.3) under drought stress condition on 17th March (Table 1). Root structure, function, and movement depend on the soil moisture content, and the root density in the subsurface horizon determines the root response to drought stress [64]. 2016). Means comparisons for different genotypes showed that the three studied genotypes showed identical performance for tiller number and plant yield. FOT was significantly earlier in DS2015 than in WS2014 (Table 2), supporting the result of Bheemanahalli et al. Mild water stress (S1) and severe water stress (S2), respectively, had moderate and severe negative effects on all the studied traits. Figure 7. 2009; Farooq et al. ISSR primers used in the study and their polymorphic products, R and Y in primer sequence indicate degeneration at 3 end. Drought stress is the most important abiotic factor affecting rice growth and yield reduction. The tube was put in a boiling water bath for 15min. However, mutant line MT58 showed different banding patterns in 7 out of 41 SSR loci, including RM1, RM3510, RM3233, RM1146, RM206, RM3873, and RM505. Means comparisons of chlorophyll contents of flag leaf as influenced by water stress and genotype in reproductive phase, Values with common letters on each column have not significant differences at 5% level of probability, Reaction of the studied genotypes to water deficit in chlorophyll contents at T2 stage of panicle emergence. Both 2D images and three-dimensional (3D) images can be used for root phenotyping, and each method has strengths and weaknesses. Effect of drought stress on yield, proline and chlorophyll contents in three chickpea cultivars. Plant-soil feedbacks: A meta-analytical review. Interestingly, one genotype carrying two drought tolerant QTLs (qDTY3.2 +qDTY12.1) with the Sabitri genetic background (IR106522-35-5-3-1-B) had high heat tolerance with less than 10% spikelet sterility (Table 3). Haussmann BIG, Mahalakshmi V, Reddy BVS, Seetharama N, Hash CT, Geiger HH. PJ01451201), Rural Development Administration, Republic of Korea, and the Basic Science Research Program through the National Research Foundation of Korea (NRF), funded by the Ministry of Education (2019R1A6A1A11052070). Bielach A., Hrtyan M., Tognetti V.B. Analysis of variance (ANOVA) showed that water stress significantly affected morphological traits, including plant height (PLH) and plant yield (PY) (Table2), indicating that these traits were highly affected by irrigation regime. Seasonal drought is a major threat to rice production. 14.0.0. Learn more Comparing water input and water productivity of transplanted and direct-seeded rice production systems.

Rice breeding programs have largely focused on understanding the plants response to various abiotic and biotic stresses to enhance yield [23]. Is early morning flowering an effective trait to minimize heat stress damage during flowering in rice? However, DA8 expressed higher value of sheath starch compared to control condition. The root images were analyzed after the staining of roots with powdered active charcoal. The plant organs, such as leaf and root, orchestrate defense mechanisms (internal or external) in response to abiotic stress [9,10,11]. Root pulling resistance is also considered to be linked with biomass, as well as root thickness and branching, and is an indirect approach to screen drought-tolerant genotypes with large root systems [160]. Get the latest news and analysis in the stock market today, including national and world stock market news, business news, financial news and more Here, we have reviewed the effects of drought stress on the growth, phenology, water and nutrient relations, photosynthesis, assimilate partitioning, and respiration The objective of this Federal government websites often end in .gov or .mil. The role of plasma membrane intrinsic protein aquaporins in water transport through roots: Diurnal and drought stress responses reveal different strategies between isohydric and anisohydric cultivars of grapevine. The results expressed that proline was highly accumulated in leaves and sheaths of rice plants under drought stress compared to control condition, and that more severe drought stress resulted to more proline accumulation. DA8 and Thierno Bande normally expressed lower sheath water contents than other varieties in 2015. vulgare and ssp. Finally, differential trends in the synchronization of diurnal changes in root hydraulic conductivity and leaf water potential between genotypes were identified, which might increase the water use efficiency in plants [79]. Under drought stress conditions, PWP reached as low as approximately 2.0 MPa across days when flower opening time was observed in DS2014 (Figure 2A), whereas PWP was at a similar level as that in the flooded condition on 6th September then it declined to 2.0 MPa on 10th September in WS2014 (Figure 2B). Water deficit considerably affected chlorophyll contents. Through integrated analyses of gene expression and stress tolerance, marker transcripts for selection of drought tolerance have been identified in a wide range of rice germplasm resources using the comprehensive expression data [129]. Drought avoidance in many upland japonica varieties of rice is accomplished by extensive and deep root systems, whereas indica subspecies typically shorten their growth period [59]. Enhanced water uptake linked with deep root architecture and a specific root length was associated with a QTL in rice that also provides yield improvements under extreme water deficit [112]. Free software (openGelPhoto.tcl) allowed precise measurement of the nodal root angle from the digital images. Sakurai J., Ishikawa F., Yamaguchi T., Uemura M., Maeshima M. Identification of 33 rice aquaporin genes and analysis of their expression and function. In the flooded treatment, one panicle per plot was used per day of flower opening time observation in DS2014 (five plots), whereas 23 panicles per plot were used per day of flower opening time observation in WS2014 and DS2015 (four plots). Moderate drought significantly decreased leaf soluble sugar of varieties in both years, except for DA8 in 2015. Effect of stressgenotype interaction was significant only for plant height. Newman E., Andrews R.E. Field mini-rhizotrons were set up. Then combined the supernatants and filled up the volumetric flask by distilled water. The expression of ethylene response factor JERF1 improves drought resistance in rice [80]. A steady decrease in the ratio of drought stress to flooded conditions was observed in DS2014 and WS2014 (Figure 3A, B, D, E), whereas the ratio was relatively maintained during the period of flower opening time observation in DS2015, except for a reduction on the last day of observation on 17th March in IR64+qEMF3 (Figure 3C, F). Under control condition, soluble sugar content fluctuated through the experimental time. Under water stress, transgenic plants exhibited a delay in leaf rolling symptoms, revived rapidly upon re-watering, and maintained approximately 20% higher relative water content in the leaves and lesser decrease in plant height and yield when compared with non-transgenic ASD16 plants [119]. A recent development in root phenotyping of japonica rice is a non-destructive process involving X-ray computed tomography [114], which captures the entire root system in soil pots in situ using transparent media that mimics field conditions [115]. Metabolism of soluble sugar and starch in rice was affected by both drought stress condition and characteristics of varieties. When drought stress increased from moderate to severe drought, DA8 was the only variety which leaf proline content significantly increased from 24.60 to 30.11mol g1 DW. Bethesda, MD 20894, Web Policies Panicle temperature was manually measured at 08300900H and 10301100H on 28 February 2014 (DS2014), and 7 September 2014 (WS2014) during the flowering period. Therefore, this study aimed to evaluate the adaptation response of production, morphological, and physiological character of several water-efficient rice varieties under drought stress in the field. However, more severe warming, floods, and drought may reduce yields. Like heat stress, rice is most susceptible to drought stress at flowering (OToole, 1982). QTL mapping of stay-green in two sorghum recombinant inbred populations. Image sequences were captured daily for each plant root system grown in the growth medium, consisting of 40 silhouette images taken every 9 for the entire 360 of rotation. ns; not significant at 5% level. Recent climate change has increased the risk of yield loss in crops due to extreme events, such as heat and drought (Ciais et al., 2005; Lesk et al., 2016; Lobell et al., 2013). (2015), the level of heat tolerance of IR64+qEMF3 was similar to that of IR64. 1Department of Biotechnology, Faculty of New Technologies, Shahid Beheshti University, Tehran, Iran, 2Department of Plant Breeding and Biotechnology, Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran. Cluster analysis differentiated the two mutant lines from wild-type line Neda and they were placed in a separate group with a high bootstrap support (Fig. 8600 Rockville Pike The X-factor: Visualizing undisturbed root architecture in soils using X-ray computed tomography. Careers. Zhao T., Dai A. They observed when rice genotyped exposed to water deficit, panicle length and fertile grains in two tolerant varieties were not significantly decreased, leading to greater productivity than in two sensitive cultivars (Cha-um et al. Rice absorbs very little or no soil water at 60 cm depth [61]. Because of water deficit, water content in leaves and sheaths of varieties were significantly lower compared to control (well-watered) condition (Figure 3). Quantification of soluble sugars and starch content in leaves and sheaths in both years were carried out follow the method of Yoshida et al. Zhao J., Bodner G., Rewald B., Leitner D., Nagel K.A., Nakhforoosh A. Root architecture simulation improves the inference from seedling root phenotyping towards mature root systems. In rice, DSM1 is a Raf-like MAPKKK gene that encodes a putative mitogen-activated protein kinase kinase. Water security is the main goal of water policy and water management.A society with a high level of water security makes the most of water's benefits for humans and ecosystems and limits the risk of destructive impacts associated with water. In the vertical root crown approach, the roots are connected to the roof of a rhizobox, and then images are collected by a horizontally-attached camera (Figure 1b). This order remained until severe drought with the leaf water content of varieties were 19.92% for DA8, 9.30% for Kinandang Patong and 7.04% for Malagkit Pirurutong, respectively. In ethanol-treated plants, there seem to be two phases of the drought stress response. Thus, this article reviews the root response to drought stress in rice. Gorgan University of Agricultural Sciences and Natural Resources, Gorgan, Iran. This shows that Jatiluhur and sharing sensitive information, make sure youre on a federal Correlation analysis showed that among morphological traits, panicle length (PL) had highest (0.862) significant correlation with plant yield, followed by fertile kernels (FK) per panicle (0.455), and tiller number (TN) (0.45), and all chlorophyll contents had a high significant positive correlation (>0.64) with plant yield (Table7). As phenotyping for genetic research is usually accomplished in controlled environmental conditions, cautious interpretation of such processes is required in root studies, as a lack of quantitative or qualitative phenotypic information may lead to inconsistencies in QTL and gene locations [107,108,109]. Rice (Oryza sativa L.) is grown in a wide range of ecosystems, including flood- and drought-prone environments [1]. Values are the mean standard deviation (n=4 plots). Semantic Scholar is a free, AI-powered research tool for scientific literature, based at the Allen Institute for AI. Get information on latest national and international events & more. Livestock may be at risk, both directly from heat stress and indirectly from reduced quality of their food supply. Put the test tube into an ice bath and then 10 mL of anthrone reagent was slowly added into the test tube. Yield loss due to water deficit of studied genotypes at two water deficit levels relative to normal irrigation condition. (A, D) DS2014, (B, E) WS2014, and (C, F) DS2015. In addition, our high-temperature chamber experiment showed wide variation in heat tolerance among advanced drought breeding lines and released varieties; heat susceptibility of IR 102777-5-83-1-2-2 was as high as Moroberekan, and IR 87707445-B-B-B, IR106523-24-6-1, and IR 10652237-36-1 were identified as moderately-heat susceptible genotypes (Table 3). Cruz and Pastenes (2012) found that a drought-resistant variety of broad bean (Phaseolus vulgaris) degraded more starch than a drought-sensitive variety. National Library of Medicine Air humidity and air temperature inside the greenhouse were measured using a TR 72wf Thermo Recorder (T&D Corporation, Nagano, Japan). Alfalfa root crowns were separated from the aboveground foliage. Barnabas B., Jager K., Feher A. The relative water content (%) in the leaves and sheaths of each variety was calculated based on the equation: Relative water content (%)=((Fresh weight Dry weight)/Fresh weight) 100. In addition, changes in internal metabolic reactions and signaling pathways are indispensable. The level of heat tolerance of three genotypes (IR 87707445-B-B-B, IR106523-24-6-1, and IR 10652237-36-1) was classified as between Moroberekan and the moderately heat tolerant check cultivar IR64. Joshi D.C., Singh V., Hunt C., Mace E., van Oosterom E., Sulman R., Jordan D., Hammer G. Development of a phenotyping platform for high throughput screening of nodal root angle in sorghum. Experiments have shown that rice DREB transcription factors also work as vital regulators in ABA-independent drought responses [126]. Put the tubes in a boiling water bath for exactly 7.5min and then immediately cooled in an ice bath. There was no significant difference in leaf soluble sugar content between control and treatment pots at 1 day re-watering after moderate drought and days re-watering after moderate drought in 2017 (Figure 6(b)). Kishor P.K., Sangam S., Amrutha R., Laxmi P.S., Naidu K., Rao K.S., Rao S., Reddy K., Theriappan P., Sreenivasulu N. Regulation of proline biosynthesis, degradation, uptake and transport in higher plants: Its implications in plant growth and abiotic stress tolerance. Register to receive personalised research and resources by email. Medrano H., Escalona J.M., Bota J., Gulias J., Flexas J. With the advancement in breeding strategies to develop drought-tolerant crops, focusing on the whole plant and root characteristics, and studying patterns of root growth in varying locations and time is advantageous [33]. In fact, collective evidence showed an example that rice variety KDML-105 is known as a relatively drought tolerant cultivar (Kameoka et al., 2016) but is heat susceptible (Shi et al., 2015) without the EMF trait (Hirabayashi et al., 2015). One day after re-watering, proline content in leaves and sheaths of varieties was rapidly decreased and significantly lower than those under respective drought stress. The number of open spikelets per panicle changed in a different manner among seasons (Figure 3). Cited by lists all citing articles based on Crossref citations.Articles with the Crossref icon will open in a new tab. Verma V, Foullces MJ, Worland AJ, Sylvester-Bradley R, Caligari PDS, Snape JW. Proline metabolism was found to be strongly responsive to certain carbohydrates, especially when the intercellular concentrations exceeded a certain threshold, thought to occur as a result of water-deficit stress [97]. Furthermore, various genes that encode proteins linked with the cytokinin signaling pathway were affected differently by abiotic stresses [84].

Cited by lists all citing articles based on Crossref citations.Articles with the Crossref icon will open in a new tab. Root hairs increase the contact area of roots with soil particles and thereby aid in absorbing soil water [41]. The second factor was rice varieties, consisting of eight varieties, i.e., Jatiluhur, IPB 3S, IPB 9G, Hipa 19, Mentik Wangi, Ciherang, Inpari 17, and Mekongga. In IR64+qEMF3, the water treatment did not affect either FOT50 or FOT90 in DS2014, whereas both FOT50 and FOT90 were significantly earlier under drought stress conditions than flooded conditions in DS2015 (Table 2). To overcome severe water shortage, the root cells must activate mechanisms to tackle water loss and its related effects. Neda with high (33 and 31%, respectively) yield loss. Fukao T., Xiong L. Genetic mechanisms conferring adaptation to submergence and drought in rice: Simple or complex? Roots are the primary plant organs to detect soil condition alterations, with a vital role in response to water stress [31]. In contrast, several studies also reported an increase in starch accumulation under stress (Kaplan & Guy, 2004; Siaut et al., 2011; Skirycz et al., 2010; Wang et al., 2013). Drought-tolerant rice. Rice is one of the most drought-susceptible crops, especially at the reproductive stage (Agarwal et al. Rain-fed rice can also penetrate hardpan, an ability critical for establishing a deep root system to improve adaptation to drought stress [63]. Ren D., Rao Y., Wu L., Xu Q., Li Z., Yu H., Zhang Y., Leng Y., Hu J., Zhu L. The pleiotropic ABNORMAL FLOWER AND DWARF1 affects plant height, floral development and grain yield in rice. Sensitivity of growth of roots versus leaves to water stress: Biophysical analysis and relation to water transport. government site. Certain modifications in the synthesis, transport, and signaling of auxin profoundly affect drought resistance in rice. Although our pot experiment restricted the root growth of drought-tolerant genotypes tested, this result could determine a breeding priority to confer the EMF trait to drought tolerant lines with high or moderately high heat susceptibility. 2014). These findings suggested that under normal and moderate drought stress conditions, water was primarily stored in sheath of rice plants.
