Alternative splicing of the FLOWERING LOCUS C-like gene MaMADS33 is associated with endodormancy in mulberry.

ABSTRACT: Alternative splicing (AS) is an important post-transcriptional process that generates multiple mRNA isoforms. FLOWERING LOCUS C (FLC) is a pivotal gene in both the vernalization and autonomous pathways of flowering plants, and MaMADS33 is one of the FLC homologs in white mulberry (Morus alba). Recent studies have revealed that MaMADS33 is involved in endodormancy, but the underlying molecular mechanism remains to be characterized. Here, a comparison of MaMADS33 expression among three mulberry cultivars with different degrees of dormancy revealed a positive association between MaMADS33 expression and dormancy. Further 3' and 5' rapid amplification of cDNA ends (RACE) analyses led to identifying four MaMADS33 isoforms derived fro
