Chromosome level genome assembly of Camellia sinensis ‘Yuwan Xiaoye’

Tea is one of the oldest crops in the world and is of great economic value as a beverage. Its natural flavor and compounds related to health exhibit significant genetic diversity. This article reports the chromosome-scale genome assembly map of a new Camellia sinensis 'Yuwan Xiaoye' (YWXY) bred by our research center. The genome size is 3.18 Gb with a contig N50 of 181.8 Mb, and 93.43% of the assembled sequences were anchored to 15 chromosomes. The genome is predicted to contain 40,119 protein-coding genes, with 99.70% having functional annotations. Repeat elements account for approximately 82.21% of the genomic landscape. The completeness of YWXY genome assembly is highlighted by a BUSCO score of 99.07%. The assembled genome provides a critical resource for molecular breeding and functional studies in tea plants.
