ARF5 — Cicer arietinum

Summary

ARF5 on chickpea chromosome 5 encodes an auxin response factor, a DNA-binding transcription factor with miRNA binding, protein binding and homodimerization activities, and is localized to the nucleus and cytoplasm. The gene is associated with auxin response, lateral root morphogenesis, flower and fruit development, sepal and petal development, abaxial cell fate specification, pattern specification, geotropism, vegetative phase change, developmental growth, regulation of anthocyanin anabolism, and response to carbohydrate. It is linked to traits including drought tolerance, high temperature stress response, phototropism, lateral root number and length, root meristem development, flowering time, seed growth, leaf morphology, stem and leaf senescence, callus induction, osmotic response sensitivity, sulfur content, brassinosteroid content, and vascular tissue morphology. Studies of related genes in other species link the family to apical-basal patterning, vascular tissue development, lateral root organogenesis, and shoot formation.
