MYB44 — Arabidopsis thaliana

Summary

AT5G67300 (MYB44) encodes a MYB transcription factor with sequence-specific DNA binding, abscisic acid binding, protein kinase activity, and protein phosphatase inhibitor activity. In Arabidopsis, MYB44 is associated with salt and osmotic stress tolerance, leaf senescence, anthocyanin accumulation, chlorophyll content, and resistance to green peach aphid and diamondback moth. It has been linked to salicylic acid- and jasmonic acid-mediated defense, jasmonate-responsive gene expression, and transcriptional regulation. The gene is connected to root elongation, salinity response, and expression of MKK4, MKK5, MPK3, and MPK5. Associations also include sodium content, phenolic compound content, submergence tolerance, UV light sensitivity, and relative growth rate. Studies of related genes in other species link the family to drought recovery, fruit expansion, and sucrose accumulation.
