摘要： The pathogenic fungus Pestalotiopsis versicolor is a major etiological agent of fungal twig blight disease affecting bayberry trees. However, the lack of complete genome sequence information for this crucial pathogenic fungus hinders the molecular and genetic investigation of its pathogenic mechanism. To address this knowledge gap, we have generated the complete genome sequence of P. versicolor strain XJ27, employing a combination of Illumina, PacBio, and Hi-C sequencing technologies. This comprehensive genome sequence, comprising 7 chromosomes with an N50 contig size of 7,275,017 bp, a GC content ratio of 50.16%, and a total size of 50.80 Mb, encompasses 13,971 predicted coding genes. By performing comparative genomic analysis between P. versicolor and the ge-nomes of eleven plant-pathogenic fungi, as well as three closely related fungi within the same group, we have gained initial insights into its evolutionary trajectory, particularly through gene family analysis. These findings shed light on the distinctive characteristics and evolutionary history of P. versicolor. Importantly, the availability of this high-quality genetic resource will serve as a foundational tool for investigating the biology, molecular pathogenesis, and virulence of P. versicolor. Furthermore, it will facilitate the development of more potent antifungal medications by uncovering potential vulnerabilities in its genetic makeup.
