Quercus fabri genome information and amino acid metabolic profile

Quercus fabri is a common timber oak tree species widely distributed in subtropical areas of China. In this study, we present a chromosome-scale reference genome assembly of Q. fabri achieved by integrating PacBio Sequel II, DNBseqTM and Hi-C sequencing platforms. Genome evolution analysis revealed that Q. fabri is closely related to Q. mongolica, with both species sharing a common ancestor approximately 20.1 million years ago. Subsequently, we performed an amino acid metabolic profile analysis on Q. fabri and related species, including Q. aliena, Q. acutissima, and Q. variabilis. The findings revealed that the overall content of amino acids in Q. fabri was significantly higher than that in the other three oak species.,<br>
