Comparative transcriptome analysis of wheat embryo and endosperm responses to ABA and H2O2 stresses during seed germination.

ABSTRACT:

Background

Wheat embryo and endosperm play important roles in seed germination, seedling survival, and subsequent vegetative growth. ABA can positively regulate dormancy induction and negatively regulates seed germination at low concentrations, while low H2O2 concentrations promote seed germination of cereal plants. In this report, we performed the first integrative transcriptome analysis of wheat embryo and endosperm responses to ABA and H2O2 stresses.

Results

We used the GeneChip® Wheat Genome Array to conduct a comparative transcriptome microarray analysis of the embryo and endosperm of elite Chinese bread wheat cultivar Zhengmai 9023 in response to ABA and H2O2 treatments during seed germination. Transcriptome profiling showed that after H2O2 and ABA treatments, the 64 d
