Insights into the Superrosids phylogeny and flavonoid synthesis from the telomere-to-telomere gap-free genome assembly of Penthorum chinense Pursh.

ABSTRACT: The completion of the first telomere-to-telomere (T2T) genome assembly of Penthorum chinense Pursh (PC), a prominent medicinal plant in China, represents a significant achievement. This assembly spans a length of 257.5 Mb and consists of nine chromosomes. PC's notably smaller genome size in Saxifragales, compared to that of Paeonia ostii, can be attributed to the low abundance of transposable elements. By utilizing single-copy genes from 30 species, including 28 other Superrosids species, we successfully resolved a previously debated Superrosids phylogeny. Our findings unveiled Saxifragales as the sister group to the core rosids, with both being the sister group to Vitales. Utilizing previously characterized cytochrome P450 (CYP) genes, we predicted the compound classes that
