MYB30 — Arabidopsis thaliana

Summary

AT3G28910, designated MYB30 in Arabidopsis thaliana, encodes a protein containing a Myb DNA-binding domain. The protein localises to the nucleus and cytosol and exhibits sequence-specific DNA binding, transcription regulator activity, and protein kinase activity. MYB30 is associated with the hypersensitive response and defense against bacterial pathogens, as well as salicylic acid accumulation and abscisic acid sensitivity. It has been linked to long-chain and very-long-chain fatty acid metabolism, anthocyanin biosynthesis, and epidermal development. Associations also include brassinosteroid and gibberellin signaling, photoperiod-sensitive flowering time, stem elongation, root hair growth, seed dormancy, and responses to temperature stress, high light, submergence, and hypoxia. Studies of related MYB30 family members in tomato link the family to cuticular wax composition and disease resistance.
