BHLH10 — Asparagus officinalis

Summary

A4U43_C04F9280, symbol AoBHLH10, encodes a BHLH domain-containing protein with transcription coactivator activity and E-box binding, localised to the nucleus. In asparagus, it is associated with the regulation of anthocyanin and flavonoid biosynthesis, jasmonic acid and salicylic acid signalling, gibberellic acid homeostasis, seed dormancy, trichome morphogenesis, anther wall tapetum development, programmed cell death, hyperosmotic salinity response, and phloem transport. The gene is linked to numerous traits including anthocyanin content, male sterility, pollen fertility, seed set, shoot and stem elongation, flowering time, leaf senescence, root morphology, and cytokinin and gibberellic acid sensitivity. Studies of related genes in other species connect the family to tapetum development, pollen viability, dwarfism, drought tolerance, chlorophyll degradation, and nitrogen metabolism.
