title: Isolation and molecular evolutionary analysis of a cytochrome c gene from Oryza sativa (rice)
abstract: A cytochrome c gene, OsCc-1, from rice (Oryza sativa) has been isolated and analyzed. The OsCc-1 gene encodes a cytochrome c protein that is typical of higher-plant cytochrome c proteins. OsCc-1 consists of three exons separated by two introns that are 817 and 747 bp in length, respectively. From genomic DNA hybridization analysis, OsCc-1 appears to be one of possibly two cytochrome c genes in several Asian, American, and Indian rice species and varieties surveyed. A single, unique cytochrome c gene appears to be present in one African cultivated rice species. We performed comparative molecular evolutionary analyses of OsCc-1 and other cytochrome c genes. We calculated a unit evolutionary period of 19.4 Myr for cytochrome c DNA sequences, which agrees closely with previous estimates based on protein sequence comparisons.
