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

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.
