Transcriptomic data during seed maturation in dormant and non-dormant genotypes of wheat (Triticum aestivum L.)

Abstract

The present data profiles a large scale transcriptome changes in seed tissues (embryo and endosperm) during maturation in dormant and non-dormant genotypes of hexaploid wheat. Seed dormancy is an adaptive trait that has a significant influence on the incidence of preharvest sprouting, which is referred to as the germination of grains on the spike prior to harvest, in wheat. Given that preharvest sprouting causes a substantial yield and quality losses, elucidation of the molecular features that regulate seed dormancy has a paramount significance in the development of preharvest sprouting resistant wheat cultivars. The data presented here was produced from total RNA/mRNA samples isolated from developing seeds of dormant and non-dormant wheat genotypes using the Affymetrix GeneChip Wheat Genome Array. The raw and normalized formats of these data are available in Gene Expression Ominbus (GEO), NCBI's gene expression data repository, with accession number GSE83077.
