Strawberry cryptochrome FvCRY1 and FvCRY2 transcriptionally regulate anthocyanin biosynthesis and sugar metabolism.

ABSTRACT: Anthocyanin pigmentation and soluble sugar content are important factors affecting the quality of strawberry fruits, and their accumulation processes are profoundly influenced by light signals. However, the molecular mechanism through which light regulates this process remains to be fully elucidated. Here, we identified two blue light receptors, FvCRY1 and FvCRY2, from woodland strawberry. Functional complementation in Arabidopsis cryptochrome mutant confirmed their photoperceptor roles. Stable overexpression of FvCRYs in cultivated strawberry (Fragaria × ananassa 'Ningyu') significantly enhanced anthocyanin accumulation and soluble sugar content, concomitant with upregulation of key biosynthetic genes. Strikingly, yeast one-hybrid and dual-luciferase assays revealed FvCRYs possess intrins
