Project description:Purpose: The goal of the study is to compare the transcriptomic differences of the flag-leaf tissue at the reproductive-stage of the Introgression Line (IR 96321-1447-165-B-3-1-2), which is drought-tolerant, to Swarna (recipient parent), which is drought-sensitive.

Identification of drought responsive genes at reproductive stage in upland rice variety Nagina22 through comparative microarray analysis

Project description:In the current study we did microarray of upland rice cultivar Nagina22 for drought stress at reproductive stage (panicle initiation) and analyzed drought stress responsive genes. We have taken flag leaf for our study as it is most essential organ for photosynthesis in rice. Normal watering Vs Drought Stress Flag leaf of Control (Three biological replicates) plant of Nagina22: C1, C2, C3 Flag leaf of drought stressed (Three biological replicates) plant of Nagina 22: S1, S2, S3

Transcriptome profiling of reproductive stage flag leaves of wheat from drought susceptible parent WL711, drought tolerant parent C306 and drought susceptible and drought tolerant RIL bulks in irrigated and drought condition

Project description:The aim of the study was to identify candidate genes responsible for drought tolerance trait between a pair of wheat varieties ( WL711 and C306) and correspondng progeny bulks (10 drought susceptible RILs and 10 drought tolerant RILs) by combining QTLs analysis with expression analysis. Microarray analysis of RNA extracted from the flag leaves showed large number of differentially expressed genes. The number of differentially expressed genes was reduced to 37 on the basis of their occurance in a major QTL region (responcible for drought tolerance) detected in RIL population derived from WL711 and C306. RNA from the reproductive stage flag leaf of wheat in irrigated and drought condition of drought susceptible parent WL711, drought tolerant parent C306 and drought susceptible and drought tolerant RIL bulks were analysed in three different biological replications (A , B and C) making total twenty four samples

Comparative Transcriptomics and Co-Expression Networks Reveal Tissue- and Genotype-Specific Responses of qDTYs to Reproductive-Stage Drought Stress in Rice (Oryza sativa L.).

Project description:Rice (Oryza sativa L.) is more sensitive to drought stress than other cereals. To dissect molecular mechanisms underlying drought-tolerant yield in rice, we applied differential expression and co-expression network approaches to transcriptomes from flag-leaf and emerging panicle tissues of a drought-tolerant yield introgression line, DTY-IL, and the recurrent parent Swarna, under moderate reproductive-stage drought stress. Protein turnover and efficient reactive oxygen species scavenging were found to be the driving factors in both tissues. In the flag-leaf, the responses further included maintenance of photosynthesis and cell wall reorganization, while in the panicle biosynthesis of secondary metabolites was found to play additional roles. Hub genes of importance in differential drought responses included an expansin in the flag-leaf and two peroxidases in the panicle. Overlaying differential expression data with allelic variation in DTY-IL quantitative trait loci allowed for the prioritization of candidate genes. They included a differentially regulated auxin-responsive protein, with DTY-IL-specific amino acid changes in conserved domains, as well as a protein kinase with a DTY-IL-specific frameshift in the C-terminal region. The approach highlights how the integration of differential expression and allelic variation can aid in the discovery of mechanism and putative causal contribution underlying quantitative trait loci for drought-tolerant yield.
