PPP1CA and legionellosis: As for functional enrichment analysis (Supplementary Table S11), the KEGG pathway had four significant functions, called “regulation of actin cytoskeleton,” “glycosylphosphatidylinositol (GPI)-anchor biosynthesis,” “Legionellosis”, and “glutathione metabolism” (p-value < 0.05), as well as five genes (ITGAE, PPP1CA, GPAA1, HSF1, and OPLAH) related to disease resistance, growth, and heat stress (Supplementary Table S10).
