SLR — Solanum lycopersicum

Summary

SlSLR (SOLYC06G008590.3) encodes an AUX/IAA family protein containing AUX/IAA and PB1 domains, with DNA-binding transcription factor activity and auxin receptor activity. In tomato, SlSLR is associated with auxin signalling, root system development, meristem initiation, inflorescence phyllotactic patterning, dedifferentiation, and dehiscence. The gene is linked to numerous agronomic traits including fruit senescence quality, seed weight, leaf chlorophyll content, shoot dry weight, root branching, adventitious root number, peduncle length, floral organ number, petal size and morphology, phyllotaxy, and phototropism response. SlSLR is also connected to stress tolerance, disease resistance, drought tolerance, senescence, chlorophyll degradation, and abscisic acid content. Studies of related genes in other species link the AUX/IAA family to lateral root development, root meristem growth, vascular tissue development, shoot formation, and auxin resistance.
