A telomere-to-telomere genome assembly of Camellia nitidissima.

ABSTRACT: Camellia nitidissima is the model species of the Camellia sect. Chrysantha Chang, the only lineage within the genus Camellia known to produce golden-yellow flowers. This species holds high aesthetic, germplasm and medical value. Unfortunately, due to excessive collection and habitat loss, C. nitidissima is classified as a critically endangered plant. In this study, we assembled a telomere-to-telomere (T2T) genome of C. nitidissima by incorporating PacBio HiFi and Hi-C data. The assembled genome consisted of 15 pseudo-chromosomes, with a total size estimated to be 2.72 Gb. The GC content and repetitive sequences occupied 38.05% and 84.38% of the assembled genome, respectively. In total, 35,701 protein-coding genes were annotated. Multiple evaluation methods confirmed the contiguity (contig
