Genomic and methylomic signatures associated with the maintenance of genome stability and adaptive evolution in two closely allied wolf spiders

PARDOSA Spiders, belonging to the family of Loycosidae Lobo spiders, play a vital role in maintaining the health of forest and agricultural ecosystems due to their function in pest control. This study presents sets of genomes at the chromosome level for two allies. PARDOSA species, P. Laura and P. Agrarian. The genomes of both species show a notable expansion of transpononable hellitron elements, which contributes to its large genome sizes. Methyloma analysis indicates that P. Laura It has general levels of high DNA methylation compared to P. Agrarian. DNA methylation not only helps the expansion of the transpononable genome of elements, but also positively affects the three -dimensional organization of P. Laura After the amplification of the transposon, potentially improve the stability of the genome. Genes associated with hyper-diferential methylated regions in P. Laura (compared to P. Agrarian) They are enriched in functions related to RNM processing and energy production. In addition, the combined profile of transcriptoma and methyloma has discovered a complex regulatory interaction between DNA methylation and gene expression, emphasizing the important role of the methylation of the gene body in the regulation of gene expression. Comparative genomic analysis shows a significant expansion of cuticle protein and gene families related to detoxification in detoxification in P. Laurathat can improve its adaptability to several habitats. This study provides essential genomic and methylomic ideas, offering a deeper understanding of the relationship between transpononable elements and genome stability, and illuminating adaptive evolution and differentiation of species between allied spiders.
