Comparative transcriptome sequencing of tolerant rice introgression line and its parents in response to drought stress.

ABSTRACT:

Background

Rice (Oryza sativa. L) is more sensitive to drought stress than other cereals, and large genotypic variation in drought tolerance (DT) exists within the cultivated rice gene pool and its wild relatives. Selective introgression of DT donor segments into a drought-sensitive (DS) elite recurrent parent by backcrossing is an effective way to improve drought stress tolerance in rice. To dissect the molecular mechanisms underlying DT in rice, deep transcriptome sequencing was used to investigate transcriptome differences among a DT introgression line H471, the DT donor P28, and the drought-sensitive, recurrent parent HHZ under drought stress.

Results

The results revealed constitutively differential gene expression before stress and distinct global transcriptome reprogra
