The haplotype-resolved T2T genome of teinturier cultivar Yan73 reveals the genetic basis of anthocyanin biosynthesis in grapes

The cultivar "Yan73' was used for assembling the first T2T genome of teinturier grapes by applying the PacBio Sequel Ⅱ platform, Hi-C technology and ultralong Oxford Nanoore Technologies (ONT) . Two haplotypes genomes were assembled, with the sizes of 501Mb and 493.38 Mb. The Yan73' sequencing on the PacBig Sequel Ⅱ platform generated a total of 29.41 Gb HiFi reads and two haplotypes were finally assembled.
We employed K-mers to assess genomic heterozygosity, estimating it at 1.35%. BUSCO was used to evaluate genomic completeness, with approximately 98.4% completeness for Yan73 haplotype 1 and 98.1% for Yan73 haplotype 2 in terms of core conserved plant genes within the genome assembly. The first genome of the teinturier grape Yan73 was successfully assembled, identifying 334,930 and 34,919 genes in haplotype 1 and haplotype 2 genomes, respectively.
