TRFL9 — Brassica oleracea var. botrytis

Summary

BoTRFL9 (TRFL9) on cauliflower chromosome 1 encodes a protein with a Myb domain, SANT/Myb domain, and ubiquitin-like domains, and is annotated with anthranilate phosphoribosyltransferase activity, DNA bending, telomeric repeat binding, and RNA binding. It is associated with regulation of telomere maintenance, positive regulation of telomere maintenance via telomerase, cellular response to UV-C, tryptophan formation, stem cell population maintenance, root meristem growth, and meristem maintenance. The gene is linked to seed viability, flowering time, disease tolerance, and phenotypes including tryptophan auxotrophy, stunted growth, reduced fertility, and telomere shortening. It localizes to the nucleus, chromosome telomeric region, and plastid. Related genes in other species are linked to telomere length regulation, cell death, and plant viability.
