摘要： Cryptochromes (CRYs), as essential blue-light photoreceptors, play pivotal roles in modulating plant growth, development, and stress responses. Although CRY-mediated light signaling has been extensively studied in model species, their functions remain limited in wheat. In this work, a comprehensive analysis of the TaCRY gene family was performed in wheat, identifying 12 TaCRY members localized to distinct chromosomes 2, 6, and 7. TaCRYs contain the conserved PHR and CCT domains and diverse gene structures. Collinearity relationships indicated their dynamic evolution patterns during polyploidization. Cis-acting elements of TaCRY members associated with light responsiveness, phytohormone signaling, and abiotic stress were also identified. Transcriptome analysis revealed that the differential expression patterns of TaCRY members under seed vigor process. This study expands our understanding of TaCRY diversity and provides valuable molecular information for marker-assisted selection in wheat improvement.
