C3H3 — Phaseolus vulgaris

Summary

PHAVU_008G214600, symbol C3H3 (also known as PvC3H3, PvC3H26, PvZFN2), encodes a CCCH-type zinc-finger protein on French bean chromosome 8. The product possesses nuclease activity, translation initiation factor activity, mRNA binding, DNA binding, and zinc binding, and belongs to the Plant_ZF_CCCH domain family. It is associated with polyamine metabolism, translation initiation, detoxification, homeostasis, and osmotic response, and localises to the cytoplasm, nucleus, and eIF-4F complex. The gene has been linked to transpiration rate and, in overexpression studies, to salt tolerance. Studies of related genes in other species connect the family to root morphology traits and relative root length under salt conditions.
