Abstract
Grantham’s camellia (Camellia granthamiana Sealy) is a rare and endangered tea species
discovered in Hong Kong in 1955 and endemic to southern China. Despite its high conservation
value, the genomic resources of C. granthamiana are limited. Here, we present a chromosomescale draft genome of the tetraploid C. granthamiana (2n = 4x = 60), combining PacBio long-read
sequencing and Omni-C data. The assembled genome size is ∼2.4 Gb, with most sequences
anchored to 15 pseudochromosomes resembling a monoploid genome. The genome has high
contiguity, with a scaffold N50 of 139.7 Mb, and high completeness (97.8% BUSCO score). Our gene
model prediction resulted in 68,032 protein-coding genes (BUSCO score of 90.9%). We annotated
1.65 Gb of repeat content (68.48% of the genome). Our Grantham’s camellia genome assembly is
a valuable resource for investigating Grantham’s camellia’s biology, ecology, and phylogenomic
relationships with other Camellia species, and provides a foundation for further conservation
measures.
