The PKT3 gene, associated with amino acid metabolism, encodes an enzyme involved in polyketide biosynthesis—secondary metabolite that influence plant-pathogen interactions—while polyketide synthase (PKS) pathways, including the PKS10-2 pathway, are crucial for the pathogenicity of certain plant pathogens and may play roles in defense mechanisms against bacterial infections in host plants (e.g. [103]. Here, ARAF is linked to bacterial infectious disease.
