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.
目前的数据描绘了六倍体小麦休眠和非休眠基因型种子在成熟过程中种子组织（胚和胚乳）的大规模转录组变化。种子休眠是一种适应性性状，对小麦收获前发芽的发生率有重大影响，收获前发芽是指在收获前谷粒在穗上发芽。鉴于收获前发芽会导致大量的产量和质量损失，阐明调控种子休眠的分子特征对培育抗收获前发芽的小麦品种至关重要。这里呈现的数据来自使用Affymetrix基因芯片小麦基因组阵列从休眠和非休眠小麦基因型发育种子中分离的总RNA/mRNA样本。这些数据的原始格式和标准化格式可在NCBI的基因表达数据储存库基因表达综合数据库（GEO）中获取，登录号为GSE83077。
