摘要

Paradombeya sinensis is an ecologically and phylogenetically valuable tree species endemic to southwestern China, yet its genomic resources remain underdeveloped. Here, we present a haplotype-resolved, chromosome-scale genome assembly to address this gap. The assembly spans about 890 Mb with high continuity (contig N50 of 44 Mb) and completeness (99.93% of sequences anchored to 20 pseudo-chromosomes). Gene annotation identified 68,639 genes. This high-quality genome assembly will serve as a fundamental genomic resource to facilitate comprehensive conservation strategies, potential utilization, and definitive phylogenetic placement of this species.
