BRAVO — Asparagus officinalis

Summary

A4U43_C07F8060, designated AoBRAVO (also known as AoMYB56), encodes a MYB transcription factor on asparagus chromosome 7. The product contains a Myb domain and SANT/Myb domain, and is annotated with DNA-binding transcription factor activity, RNA polymerase II-specific cis-regulatory region binding, chromatin binding, and protein homodimerization activity. AoBRAVO is associated with the regulation of seed size, secondary cell wall biogenesis, lignin anabolism, and cell division, as well as responses to brassinosteroid, drought, salinity, and red or far-red light. It is linked to quiescent center organization, plant epidermis development, and endosperm development. Associations with flowering time, root growth, seed size, shoot branching, and stress responses (oxidative, high and low temperature) have been noted. Studies of related genes in other species link the family to root quiescence, anthocyanin accumulation, and drought memory.
