AXR5 — Solanum lycopersicum

Summary

SlAXR5 (SOLYC03G120500.4) on tomato chromosome 3 encodes an AUX/IAA family protein containing AUX/IAA and PB1 domains, annotated with auxin receptor activity, auxin binding, transcription corepressor activity, and sequence-specific DNA binding. The gene is associated with regulation of response to stimulus, cell wall organization, cellulose metabolism, chlorophyll a breakdown, strigolactone anabolism, lycopene anabolism, inflorescence meristem growth, sepal development, and dehiscence. It localizes to the nucleus, cytosol, plasmalemma, plant-type vacuole, and SCF ubiquitin ligase complex. SlAXR5 is linked to traits including stem dry weight, seminal root length, root volume, leaf chlorophyll content, photosynthetic ability, fruit growth and development, water stress response, abscisic acid content, and glyphosate sensitivity. Related genes in other species are linked to auxin homeostasis, root gravitropism, and lateral root initiation.
