CCR1 — Brassica oleracea var. botrytis

Summary

BoCCR1, located on chromosome 5 of cauliflower (Brassica oleracea var. botrytis), encodes a protein with kinase-like and RCC1/BLIP-II domains and exhibits protein serine/threonine kinase activity, signaling receptor activity, and ATP binding. This gene is associated with a wide range of biological processes including macroautophagy, photoprotection, regulation of floral meristem size, lignin anabolism, and upregulation of reactive oxygen species biosynthesis. It is also linked to sepal giant cell differentiation, plant epidermal cell differentiation, floral organ development, flower morphogenesis, regulation of leaf senescence, and detection of molecules of fungal origin. The encoded protein localizes to the plasma membrane and MVB membrane. Studies of related genes in other species connect the family to non-specific serine/threonine protein kinase activity and associations with lignin content and plant height.
