ARF4 — Cucumis sativus

Summary

CsARF4 (CSA_6G291920) on cucumber chromosome 6 encodes an auxin response factor, a DNA-binding transcription factor with ARF, AUX/IAA, B3 and PB1 domains that localises to the nucleus and cytoplasm and exhibits miRNA binding, protein heterodimerisation and sequence-specific DNA binding activities. The gene is associated with fruit ripening, sepal, petal and filament development, abaxial cell fate specification, pattern specification, developmental growth, vegetative phase change, regulation of anthocyanin biosynthesis, lateral root morphogenesis, positive gravitropism and climacteric fruit ripening. It has been linked to traits including sulfur content, phototropism, stem senescence, biotic stress, lateral root number and length, callus induction, osmotic sensitivity, ethylene and auxin sensitivity, leaf morphology, high temperature stress, photosynthetic rate, root meristem development, leaf composition, hypocotyl morphology, leaf senescence, seed development, abscisic acid sensitivity, flowering time and overall plant growth.
