CRR2 — Brassica oleracea

Summary

BoCRR2 (BOLC102_C01P035490.1) on cabbage chromosome 1 encodes a pentatricopeptide repeat (PPR) protein with DYW and E motifs, and is annotated for RNA binding, pre-rRNA binding, and zinc binding. The gene is associated with chloroplast and mitochondrial RNA processing, polycistronic mRNA processing, mRNA stabilization, and positive regulation of translation. It has been linked to chloroplast NDH complex accumulation, ndhB expression, disease resistance, and systemic acquired resistance. Associations also include cytokinin response and sensitivity, root development traits including lateral root length and root stem cell differentiation, seed coat morphology and development, cell cycle traits, and plant growth and development. The protein localizes to chloroplast stroma, mitochondria, plasmodesmata, and cytosol. Related genes in other species are linked to root meristem development, epidermal cell differentiation, and embryogenesis.
