Genomic Evolution and Patterns of Horizontal Gene Transfer in Coccomorpha Species.

ABSTRACT: As a significant group of agricultural and forestry pests, Coccomorpha warrants in-depth investigation into their environmental adaptation mechanisms. This study conducted a comparative genomic analysis using five published chromosome-level genomes of Coccomorpha species. Phylogenetic analysis revealed that the divergence times of these five species ranged from 333.18 to 84.22 million years ago (mya), with each having undergone two whole-genome duplication (WGD) events. The significantly expanded gene families in these species were predominantly enriched in antioxidant-related processes such as oxoacid metabolic process, organic acid metabolic process, and carboxylic acid metabolic process. Furthermore, 260 horizontal gene transfer (HGT) acquired genes were identified across these species,
