Description
Mulberry fruit color owes much to MYB transcription factors, and Xuefei Chen and colleagues catalogued the whole family in Morus atropurpurea for a 2026 study. Genome searches using hidden Markov models and BLAST turned up 145 MYB genes, sorted into 31 subfamilies. Expression was tracked across three stages of fruit development.
One candidate, the DIV-like repressor MaDIV, faded as fruit ripened while pigment built up. When tobacco plants overproduced MaDIV, their flowers held 42 percent less anthocyanin than normal plants. The pigment gene NtDFR was strongly suppressed, while the flavonol gene NtFLS1 rose. The results point to MaDIV as a brake on coloring, useful for breeding and pigment research.
