Embryo and endosperm specific comparative transcriptome analysis of triticum aestivum in response to ABA and H2O2 stress

Abstract

Wheat seed germination directly affects wheat yield and quality. Embryo and endosperm are two main parts of wheat seed and plays crucial role in seed germination and subsequent plant growth and other development. In the process of seed germination a systematic bi-directional molecular interactions are major component and that got affected by the means of abiotic stresses. A variety of proteomic and transcriptomic approaches have been used so far to investigate seed germination process in response to abiotic stresses. In this study, we have investigated deferentially expressed genes/transcripts (DEGs) of embryo and endosperm in response to ABA and H2O2 stress by the means of stress systems biology approaches using microarray data. Further, role of DEGs in response to each stress was explored, which identify biological and molecular functions of genes during seed germination embryo and endosperm. Our results provide the insight into comparative transcriptomic mechanism of the embryo and endosperm in response to ABA and H2O2 treatment during seed germination process.
