A study on mutation and sequence polymorphism of the Rc gene will provide evidence for understanding the evolution of rice cultivars. The aim of this study was to archive a full-length genomic DNA sequence and analyze polymorphism in the Rc gene of Nepcam YB rice, a local pigmented rice in Yen Bai province. By using 18 primer pairs, full-length sequence with down-stream and up-stream of the Rc gene of NepCam YB variety was successfully assembled and aligned by BioEdit software with 7500 bp. We found that the Rc gene from NepCam YB variety contains 8 introns and 9 exons. Sequence polymorphism analysis has revealed 14 bp deletion in the fifth introns and 54 SNPs of Rc gene was detected by comparing with 8 representative rice cultivars. Next, our phylogeny analysis revealed that Nepcam YB was closely related to the Japonica Jefferson cultivar. In this study, full-length sequence of the Rc gene in red pericarp Nepcam YB was successfully archived and is preliminary data for understanding domestication of Vietnamese local rice.
