MP — Solanum lycopersicum

Summary

SlMP (SOLYC04G081240.2), also known as SlIAA24 and SlARF5, encodes a protein with DNA binding and transcription cis-regulatory region binding activity, belonging to the ARF and AUX/IAA domain families. In tomato, SlMP is associated with leaflet formation, inflorescence phyllotactic patterning, meristem growth, phloem and sieve cell development, auxin export and breakdown, hormone and carotenoid metabolism, and response to water and hormones. The gene is linked to numerous agronomic traits including fruit width, length and weight, stem strength, net photosynthetic rate, relative growth rate, adventitious and lateral root number, shoot growth angle, and abscisic acid, brassinosteroid and auxin content. Studies of related genes in other species connect the family to vascular tissue development, root meristem growth, apical-basal patterning, and stress responses including cold tolerance.
