ERA1 — Brassica oleracea var. botrytis

Summary

BoERA1 (ERA1) on cauliflower chromosome 9 encodes a GTP-binding protein of the Era family, characterised by a G_ERA domain and a KH-type RNA-binding domain. The product binds ribosomal small subunit, rRNA, mRNA and GTP, and is associated with ribosomal small subunit assembly, ribosome biogenesis, rRNA processing and ABA signalling. It localises to the chloroplast nucleoid. The gene has been connected to drought tolerance. Studies of related genes in other species link the family to leaf chlorosis, stomatal resistance and stomatal opening, though these associations are not yet established in cauliflower.
