MYB4 — Cicer arietinum

Summary

CaMYB4 (LOC101496236) on chickpea chromosome 6 encodes a plant Myb transcription factor with DNA-binding, transcription factor activity, and protein dimerization functions. It is associated with the regulation of flavonoid, anthocyanin, proanthocyanidin, lignin, and sinapate ester biosynthesis, as well as phenylpropanoid metabolism, the shikimate pathway, and green leaf volatile production. The gene is linked to trichome spacing and differentiation, seed coat development, vascular tissue patterning, shoot apical meristem specification, circadian rhythm, and UV-B response. It localises to the nucleus, cytoplasm, and root hair. Associations with agronomic traits include leaf trichome density, anthocyanin content, flowering time, seed growth, disease tolerance, salt stress tolerance, UV-B sensitivity, brassinosteroid and jasmonic acid content, iron concentration, nitrate uptake, and plant growth and development. Related genes in other species are linked to UV-B tolerance, flavonol and sinapate ester production, lignin content, trichome density, and pathogen resistance.
