SLR — Beta vulgaris subsp. vulgaris

Summary

BvSLR (BVRB_4G082260) on sugar beet chromosome 4 encodes an AUX/IAA family protein with auxin receptor activity, auxin binding, and DNA-binding transcription factor activity. It is associated with diverse developmental processes including meristem initiation and development, lateral root morphogenesis, inflorescence phyllotactic patterning, embryonic pattern specification, and positive regulation of leaf senescence. The gene is linked to traits such as root hair density, adventitious root number, leaf margin morphology, petal number and size, phyllotaxy, phototropism response, and stress tolerance. It also is linked to disease resistance, drought tolerance, senescence, and chlorophyll degradation. Studies of related genes in other species link the AUX/IAA family to lateral root development, auxin resistance, vascular tissue specification, and stress responses.
