The telomere-to-telomere haplotype genome provides in-depth insights into the molecular mechanisms of the anthocyanin deficiency phenotype in Prunus mume.

ABSTRACT: Prunus mume originated from China and is highly valued for its remarkable combination of ornamental blossoms and high economic value. Previously published P. mume genomes contain unanchored genetic regions and excessive gaps. Here, we report the P. mume f. viridicalyx gap-free telomere-to-telomere (T2T) haplotype genome. The LE_hap1 and LE_hap2 genomes were 229.29 and 228.36 Mb in length, respectively, with an N50 length of the contig between 27.65 and 27.79 Mb and 24,318 and 24,316 protein-coding genes, respectively. The completeness, continuity, and accuracy of the P. mume f. viridicalyx genome was significantly improved over the previous P. mume genomes. The key mutated genes during P. mume f. viridicalyx cultivar domestication were identified by comparative genomic, population evolutio
