WIG — Brassica oleracea var. botrytis

Summary

BoWIG, located on chromosome 4 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with protein farnesyltransferase, geranylgeranyltransferase, and prenyltransferase activities, belonging to the FTB/Prenyltrans family. This gene is associated with protein prenylation, farnesylation, and geranylgeranylation, as well as regulation of meristem development and organization, cell shape, cuticle development, and responses to osmotic stress, salinity, abscisic acid, and fungi. It is linked to traits including seed yield and root hair length. The encoded protein localizes to the nucleus and protein farnesyltransferase and geranylgeranyltransferase complexes. Studies of related genes in other species connect the family to abscisic acid signaling, meristem size, and enhanced Botrytis immunity with cuticle defects.
