Rf1 — Beta vulgaris subsp. vulgaris

Summary

BVRB_025240 (symbol Rf1) on sugar beet chromosome 107739 encodes a protein with PPR_P_subfamily, PPR_rpt, and TPR-like_helical_dom_sf domains. It has pre-rRNA binding, endonuclease activity, ssRNA binding, identical protein binding, and mRNA binding functions. The gene is associated with mitochondrial RNA processing, mRNA cis splicing via spliceosome, photosystem I assembly, pigmentation, digestion, RNA splicing, chloroplast RNA processing, group II intron splicing, mitochondrial mRNA modification, mRNA stabilization, positive regulation of translation, regulation of translation, mRNA processing, pollen development, embryo development ending in seed dormancy, and response to abscisic acid. It is linked to cytoplasmic male sterility, pollen fertility restoration, male fertility, root meristem activity, root stem cell maintenance, and ABA-hypersensitive, retarded growth, increased ROS accumulation. It localizes to chloroplast stroma, mitochondria, and cytoplasm. Related genes in other species link the family to root meristem development and abscisic acid sensitivity.
