FTSZ1 — Brassica oleracea var. botrytis

Summary

BoFTSZ1 (BOLND125_C09P048790.1) on cauliflower chromosome 9 encodes a GTPase of the FtsZ protein family, a tubulin-like component of the plastid division machinery. The gene is associated with plastid and chloroplast fission, chloroplast organization, and chloroplast movement, as well as responses to blue light, mechanical stimulus, and gibberellin. Its product localizes to the contractile ring, chloroplast thylakoid, stroma, and plastid. BoFTSZ1 is linked to chlorophyll content and fluorescence, and to plastid and chloroplast development traits. Phenotypic associations include giant, enlarged, and heterogeneous chloroplasts, thylakoid membrane organization, and plastid division. Studies of related genes in other species connect the family to chloroplast morphology.
