Camellia sinensis var. sinensis, Camellia sinensis var. assamica, Camellia taliensis, Camellia taliensis var. bangwei, Camellia crassicolumna and Camellia tachangensis Targeted Locus (Loci)
The genetic divergence between the cultivated teas (C. sinensis var. sinensis and C. sinensis var. assamica) and the wild relatives C. taliensis, C. crassicolumna and C. tachangensis belonging to section Thea genus Camellia are not clear, and the sub-classification within genus Camellia remains controversial. The limitations of phenotypic markers and the hitherto low throughput of molecular marker studies have been unable to delineate phylogenetic relationships among species in section Thea. Recent advances in restriction-site associated DNA sequencing (RAD-Seq) provide a fast, cost-effective, and reliable approach to generate genome-wide SNPs for phylogenetic analysis that is suitable for species with unsequenced genomes. An extensive SNP dataset from RAD sequencing of genomes from C. sinensis and its wild relatives in genus Camellia, section Thea represents an unprecedented coverage, useful not only for assessing genetic divergence, but also to demonstrate its usefulness in phylogenetic analysis of Camellia spp. The information described here is will be valuable for future evolutionary genetics and population studies in section Thea of the genus Camellia.
