MYB — Solanum lycopersicum

Summary

SOLYC06G053610.3, also known as MYB14, MYB13, MYB15, and ATY19, encodes a tomato transcription factor on chromosome 6 that contains a Myb domain and SANT/Myb domain, and exhibits sequence-specific DNA binding, chromatin binding, and transcription cis-regulatory region binding activities. In tomato, this gene is associated with flavonoid biosynthesis, drought tolerance, salt tolerance, and 2,4,6-trichlorophenol tolerance. It has been linked to numerous agronomic traits including fruit type, lycopene content, carotene content, grain size, seed length, ear diameter, harvest index, leaf chlorophyll content, leaf relative water content, seedling vigor, root fresh weight, shoot dry weight, and abscisic acid content. The gene is also associated with pathogen resistance, lignin biosynthesis, cold tolerance, freezing tolerance, stomatal development, flowering time, and male fertility. Studies of related genes in other species link the family to aphid resistance, cold stress tolerance, and stomatal formation.
