In an mRNA sequencing analysis (using transcriptome sequencing [RNA-Seq]) involving ΔMorgs1, ΔMorgs3, ΔMorgs4, and ΔMorgs7 mutant strains, as well as wild-type Guy11, we identified three transcriptional patterns of genes regulated by RGS proteins during the early infection stage. The gene discussed is PITX2; the disease is infection.
