LMI2 — Asparagus officinalis

Summary

A4U43_C10F16330, symbol LMI2 (also known as AoMYB5, AoMYB17, AoMYB39), encodes a Myb-domain transcription factor in asparagus (Asparagus officinalis) on chromosome 10. The product is a nuclear-localised DNA-binding protein with chromatin binding, sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, and DNA-binding transcription factor activity. LMI2 is associated with the maintenance of inflorescence meristem identity, regulation of flower development, anther wall tapetum development, anthocyanin and lignin anabolism, the shikimate pathway, green leaf volatile biosynthesis, gibberellic acid signalling, circadian rhythm, and response to cold. It is linked to traits including pedicel length, flower morphology, inflorescence development, plant male sterility, anthocyanin content, flowering time, and bacterial disease response. Studies of related genes in other species link the family to seed germination, reproductive development, floral organ patterning, and flower morphogenesis.
