Paldosa Spiders, which belong to the wolf spider family, play an important role in maintaining the health of forests and agricultural ecosystems through their pest control functions. This study presents chromosomal-level genomic assemblies from two Allied countries. Paldosa seed, P. Roller and P. Agraria. The genomes of both species exhibit a significant expansion of helitron metastatic elements, which contribute to the large genome size. Methylome analysis shows that P. Roller Compared with the above, the overall DNA methylation level is higher. P. Agraria. DNA methylation not only helps transposeable element-driven genome expansion, but also has a positive effect on the three-dimensional organization of P. Roller After transposon amplification, this potentially improves genome stability. Genes associated with hyperdefactor-methylated regions P. Roller (compared to P. Agraria) It has a wealth of features related to mRNA processing and energy production. Furthermore, the combination of transcriptome and methylome profiling revealed complex regulatory interactions between DNA methylation and gene expression, highlighting the important role of gene body methylation in regulating gene expression . Comparative genomic analysis shows a significant expansion of cuticle proteins and detoxification-related gene families P. Rollerwhich may improve adaptability to a variety of habitats. This study provides important genome and methylome insights, provides a deeper understanding of the relationship between translocation elements and genome stability, and reveals adaptive evolution and species differentiation among Allied spiders.
