ARL — Brassica oleracea var. botrytis

Summary

BoARL, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a protein belonging to the ARGOS/ARL/OSR1 family. This gene is associated with the positive regulation of organ growth, organ growth, upregulation of cell proliferation, multidimensional cell growth, cellular response to auxin stimulus, response to brassinosteroid, and brassinosteroid-mediated signalling. Its product has been linked to protoplasm, ER, membrane, mitochondria, and nucleus localisation, as well as to ethylene sensitivity and brassinosteroid response. Studies of related genes in other species connect the family to traits such as leaf size, stem size, flower diameter, root thickness, organ identity, photochemical quenching, and drought and salt tolerance, as well as to cell expansion and root growth.
