Genomics A telomere-to-telomere gap-free genome assembly of Penthorum chinense was published in 2023, representing the first telomere-to-telomere genome assembly reported for the order Saxifragales. The genome assembly spans approximately 257.5 Mb and consists of 9 chromosomes, with a BUSCO completeness of 99.7%. A total of 24,617 protein-coding genes were predicted.
