The present data profile a large scale transcriptome changes associated with variations in seed dormancy level induced by seed development temperature in hexaploid wheat. Seed dormancy is an important trait that inhibits seed germination under optimal conditions and therefore has important implication in preventing the incidence of preharvest sprouting, which refers to the germination of seeds on the mother plant prior to harvest, in wheat. Since preharvest sprouting, which causes a significant reduction in seed yield and quality in wheat, is closely associated with low level of seed dormancy manifested in modern wheat cultivars, it is important to develop wheat cultivars with optimal level of dormancy to enhance wheat yield and quality. Thus, elucidation of the molecular mechanisms that regulate seed dormancy is critical for the development of preharvest sprouting resistant wheat cultivars. The data we are presenting here were generated from total RNA samples extracted from imbibed seeds of a dormant wheat ( L.) genotype that were developed at different temperatures using the Affymetrix GeneChip Wheat Genome Array. The raw and normalized formats of these data are deposited in the NCBI's gene expression data repository, Gene Expression Ominbus (GEO) with accession number GSE153527.
目前的数据描绘了与六倍体小麦种子发育温度诱导的种子休眠水平变化相关的大规模转录组变化。种子休眠是一种重要特性，它在最佳条件下抑制种子萌发，因此对于防止小麦收获前发芽（即种子在收获前在母株上萌发）的发生具有重要意义。由于收获前发芽会导致小麦种子产量和质量显著下降，且与现代小麦品种中表现出的低水平种子休眠密切相关，因此培育具有最佳休眠水平的小麦品种对于提高小麦产量和质量很重要。因此，阐明调节种子休眠的分子机制对于培育抗收获前发芽的小麦品种至关重要。我们在此展示的数据来自使用Affymetrix GeneChip小麦基因组阵列从在不同温度下发育的休眠小麦（L.）基因型的吸胀种子中提取的总RNA样本。这些数据的原始格式和标准化格式已存入NCBI的基因表达数据储存库Gene Expression Ominbus（GEO），登录号为GSE153527。
