Telomere-to-telomere and gap-free genome assembly of a susceptible grapevine species (Thompson Seedless) to facilitate grape functional genomics.

ABSTRACT: Grapes are globally recognized as economically significant fruit trees. Among grape varieties, Thompson Seedless holds paramount influence for fresh consumption and for extensive applications in winemaking, drying, and juicing. This variety is one of the most efficient genotypes for grape genetic modification. However, the lack of a high-quality genome has impeded effective breeding efforts. Here, we present the high-quality reference genome of Thompson Seedless with all 19 chromosomes represented as 19 contiguous sequences (N50 = 27.1 Mb) with zero gaps and prediction of all telomeres and centromeres. Compared with the previous assembly (TSv1 version), the new assembly incorporates an additional 31.5 Mb of high-quality sequenced data with annotation of a total of 30 397 protein-coding gen
