EDITING SITES IN TRANSCRIPT OF MITOCHONDRIAL GENE IN HOT PEPPER
摘要
Abstract
RNA editing status of three mitochondrial genes had2, atpA and cob from hot pepper CMS line North A and its maintainer line North B were studied. For had2 the results showed that had2 and cob were edited at different degree except atpA. For had2 there were ten editing sites in CMS line, of which seven sites occurred as C-to-U changes, one as U-to-C change, the other two as C-to-G and A-to-U. However, maintainer line had only seven C-to-U editing sites. For cob gene there were six editing sites in ＇ North A＇ , of which five sites occurred as C-to-U changes and one as U-to-C change. The maintainer line preserved the five editing sites of C-to-U while lacked of the U-to-C change and added a G- to-U unique editing site. The maintainer line had obviously higher editing frequency at each editing site than the CMS line. The amino acid and hydrophobicity of the deduced protein were changed after editing, suggesting that the RNA editing might contribute to CMS property in pepper.关键词
