ARF3 — Cucumis sativus

Summary

CSA_2G049970, designated ARF3 (also known as CsARF3, ARL1, or CsARL1) in cucumber (Cucumis sativus) on chromosome 2, encodes a small GTPase of the ARF/SAR family with GTPase activity, GTP binding, and phospholipase activator activity. The protein localizes to the Golgi stack, trans-Golgi network, and cytoplasm. ARF3 is associated with sex determination, carpel and stamen development, flower and fruit development, meristem maintenance, auxin signaling, ethylene anabolism, and immune response. It has been linked to traits including root number, root length, adventitious root development, fruit growth, leaf blade expansion, leaf abaxial-adaxial polarity, anther morphogenesis, floral meristem determinacy, and somatic embryogenesis. Studies of related genes in other species connect the family to plant height, trichome formation, pollen fertility, and auxin sensitivity.
