A resource for systems analysis of transcriptional modules involved in drought response in rice

ABSTRACT: The severity of impact of drought on crops is contingent on the developmental stage of the plant, with the most sensitive stage being the reproductive stage. Hence, gene expression profiling has been used to understanding drought response and resistance mechanism in rice. Here we present drought transcriptomes of rice in three developmental stages and gain insights into the processes and regulatory mechanisms involved in common and stage specific drought responses. Total RNA was isolated from the rice seedlings, vegetative (V4) and reproductive (R4) tissues of both control and stress treated plants for hybridization on Affymetrix microarrays. Two independent replicates for seedling and reproductive stages, and three replicates for vegetative stages were generated, for both control and stress samples. For drought treatments, plants were gradually subjected to field drought conditions in order to reach 50% field capacity (FC) by regulating water supply, whereas control plants were maintained at 100% FC.

Wild and cultivated species of rice have distinctive proteomic responses to drought

Project description:Drought often compromises yield in non-irrigated crops such as rainfed rice, imperiling the communities that depend upon it as a primary food source. In this study, two cultivated species (Oryza sativa cv. Nipponbare and Oryza glaberrima cv. CG14) and an endemic, perennial Australian wild species (Oryza australiensis) were grown in soil at 40% field capacity for 7-d (drought). The hypothesis was that the natural tolerance of O. australiensis to erratic water supply would be reflected in a unique proteomic profile. Leaves from droughted plants and well-watered controls were harvested for label-free quantitative shotgun proteomics. Physiological and gene ontology analysis confirmed that O. australiensis is responded uniquely to drought, with superior leaf water status and enhanced levels of photosynthetic proteins. Moreover, distinctive patterns of expression of proteins in drought were observed across the entire O. australiensis proteome. An intermediate impact of drought on photosynthetic and stress-response proteins is reported in O. glaberrima relative to O. sativa but the drought response was most striking in O. australiensis. For example, photosynthetic proteins decreased when O. sativa after drought, while a narrower range of stress-responsive proteins was up-regulated. Distinctive proteomic profiles and the expression levels of individual proteins with specific functions in response to drought in O. australiensis indicate the importance of this species as a source of stress tolerance genes.

Distinct proteomic responses to multiple abiotic stresses in two rice genotypes

Project description:In the present study, we found that Nipponbare and IAC1131 behave equivalently in response to multiple abiotic stress, which included simultaneous application of drought, salt and temperature stress. At the level of molecular analysis by isotopic labelling quantitative proteomics, 6215 proteins were reproducibly identified and quantified across the two genotypes and three time points sampled. Heat shock proteins, late embryogenesis abundant proteins, and photosynthesis-related proteins were all found to be differentially abundant in response to stress treatments in both Nipponbare and IAC1131.

Study on the proteomic response of 5mm sections of root tips to water-deficit stress in two contrasting genotypes of rice

Project description:In this study, we analysed the proteomic response of 5mm sections of root tips to water-deficit stress in two contrasting genotypes of rice: IR64, a lowland, drought-susceptible, and shallow-rooting genotype; and Azucena, an upland, drought-tolerant, and deep-rooting genotype. Using a Partial Least Square Discriminant Analysis, we identified statistically significant differentially abundant proteins across genotypes and conditions. Analysis of biological processes led to the identification of novel proteins involved in root elongation with specific expression patterns in Azucena.

Transcriptome profile for spikelets of rice plants subjected to severe reproductive stage drought stress

Project description:To understand how the qDTY12.1 interacts with other genes within the genome to give better yield under drought; the spikelets transcriptome of DTY12.1 parents (Vandana , Way Rarem) and DTY12.1 NIL (481-B) were compared under control and drought conditions. Drought induced gene expression was studied in the spikelets of the rice plants subjected to severe reproductive stage drought. Seeds of Vandana, Way Rarem, and 481-B were sown into rotovated soil at a rate of 2.0 g m-1 into plots of 3 rows X 3 m. The three genotypes were sown in three replications in a randomized complete block design.

Project description:Global gene expression analysis of AtDREB1A transgenic rice line (TL4) at reproductive stage under drought stress was conducted using microarray to explore the drought stress-responsive transcription pathways. Drought stress was imposed at late vegetative stage till booting of the plants. Flag leaf was collected on 14th day of the drought stress. Drought stress was imposed on T3 plants of two homozygous transgenic rice events of PS2 and NT plants by withholding irrigation for 14 days in the National Phytotron Facility, IARI.

Genome-wide transcriptome analysis of rice in response to controlled drought stress at vegetative

Project description:In this study, genome-wide transcriptome profiling was used to understand molecular genetic mechanism of drought tolerance in rice. Illumina High-Seq 2000 platform was used for sequencing RNA from leaf tissue of rice plants exposed to controlled drought stress and well-watered conditions. The differentially expressed genes were used to identify biological process and cis-regulatory elements enriched under drought stress compared to well-watered conditions. Oryza sativa ssp. japonica cv. Nipponbare plants were exposed to controlled drought stress and well-watered conditions at the vegetative stage. Controlled drought (DR) stress was applied on 45 day old plants following gravimetric approach. The soil water content was brought down to 40% field capacity over a period of 3-4 days and plants were maintained at that level for 10 days by weighing the pots daily at a fixed time of the day and replenishing the water lost through evapotranspiration. Another set of plants were maintained at 100% FC as well-watered (WW) condition. Total RNA isolated from leaf tissue was used for RNA-sequencing. Two biological replicates per sample were sequenced. cDNA library was constructed using TruSeq Stranded Total RNA with Ribo-Zero Plant kit (Illumina). Sequencing was carried out on each library to generate 50 bp SE reads using Illumina High-Seq 2000 platform. The transcriptome reads were mapped to the rice reference genome sequence (MSU 7.0) with tophat1.3.1 using the program’s default parameters (http://tophat.cbcb.umd.edu). Mapped RNA-Seq reads were assembled into transcripts by Cufflinks (http://cufflinks.cbcb.umd.edu/) and differentially expressed genes were identified by using Cuffdiff.

Transcriptome analysis of Osbhlh148 mutant plants under controlled drought stress and well-watered conditions at vegetative stage

Project description:The members of bHLH transcription factor superfamily are known to play key role in plant development and abiotic stress response. Loss-of-function of OsbHLH148 gene resulted in increased sensitivity of rice plants to drought stress. To identify the targets of OsbHLH148 and dissect the drought stress response pathway regulated by it, we performed transcriptome profiling of Osbhlh148 mutant plants under drought stress as well as well-watered conditions by RNA-sequencing. OsbHLH148 loss-of-function rice plants (Oryza sativa ssp. japonica cv. Nipponbare) were exposed to controlled drought stress and well-watered conditions at the vegetative stage. Controlled drought (DR) stress was applied on 45 day old plants following gravimetric approach.

Transcriptome analysis of Oshsfa2e mutant plants under controlled drought stress and well-watered conditions at vegetative stage

Project description:Heat shock factors (Hsfs) are known to regulate heat and drought stress response by controlling the expression of heat shock proteins and oxidative stress responsive genes. Loss-of-function of OsHSFA2e gene resulted in increased sensitivity of rice plants to drought and heat stress.
