BRAVO — Asparagus officinalis

Summary

A4U43_C07F8160, designated AoBRAVO (also known as AoMYB56 or MYB56) on asparagus chromosome 7, encodes a MYB transcription factor with DNA-binding, chromatin-binding, and protein homodimerization activities. It is associated with the regulation of seed size, secondary cell wall biogenesis, lignin anabolism, and plant epidermis development. The gene has been linked to cellular responses to drought, salinity, brassinosteroid stimulus, and red or far-red light, as well as to the downregulation of long-day photoperiodism and flowering. Associations with traits include seed size, flowering time, shoot branching, stem elongation, leaf morphology, root thickness, and responses to high and low temperature stress, oxidative stress, and disease. Studies of related genes in other species link the family to root quiescence, anthocyanin accumulation, and drought memory.
