IAA4 — Pisum sativum
Summary
PsIAA31 (IAA4) on chromosome 4LG4 encodes an AUX/IAA family protein with DNA-binding, auxin-binding, IP6-binding, calcium-ion-binding and protein-binding activities. It is associated with auxin signalling, the TIR1-IAA-AUX/IAA interaction, ARF inactivation, and ubiquitination and degradation of AUX/IAA proteins. The gene is associated with root development, shoot development, photomorphogenesis, geotropism, stamen development, pollen maturation, mRNA stabilization, calcium signalling, and regulation of DNA-templated transcription. It localises to the nucleus, cytosol, cytoplasm, plastid, plant-type vacuole, protoplasm and SCF complex. Associations with traits include adventitious root number, lateral root length, leaf morphology, embryo development, hypocotyl morphology, salt tolerance, and plant growth and development. Studies of related genes in other species link the family to root gravitropism, adventitious root development and plant growth.
