The late spring cold disaster caused by low temperature in spring occurs frequently in China. It is of great significance to analyze the gene regulation mechanism of wheat in response to low temperature to resist the genetic improvement. In this study, the gene expression characteristics of wheat young spikes subjected to low temperature during meiosis was analyzed using transcriptome technology under artificially controlled environmental conditions. The results indicate that low temperature during meiosis stage can cause damage to the ultrastructure of anther tissue, leading to a significant decrease in seed setting rate. The differentially expressed genes (DEGs) in young spikes under low temperature mainly involve pathways such as hormone signal transduction, photosynthesis, circadian rhythm-plants, sugar metabolism, DNA replication, etc. The encoding genes of actin depolymerization factor (ADF), late embryonic development abundant protein (LEA), CCCH zinc finger protein, etc. were significantly upregulated at all time points of low temperature treatment, which may be involved in regulating the resistance response of wheat spikes to low temperature.
