ARF17 — Cicer arietinum

Summary

ARF17 on chickpea chromosome 1 encodes an auxin response factor, a B3 DNA-binding domain-containing transcription factor that localises to the nucleus and binds DNA, miRNA, and chromatin. This gene is associated with auxin signalling, lateral root morphogenesis, geotropism, sepal and filament development, fruit ripening, vegetative phase change, and regulation of anthocyanin biosynthesis. It has been linked to numerous traits including lateral root number and length, root meristem development, floral organ development, phototropism, high temperature stress response, leaf senescence, seed growth, flowering time, fruit quality, total soluble sugar content, plant male sterility, and callus induction. Related genes in other species are linked to root cap formation, columella cell differentiation, seed germination, ABA sensitivity, and stress responses.
