Upon challenge inoculation with Phytophthora capsici on Piper spp certain defense genes are induced and show a bi-modal pattern of gene expression in qPCR analysis.
Is this because Phytophthora capsici is a hemibiotrophic pathogen with both biotrophic and necrotophic stage in its life cycle or some other reason. Kindly provide any articles which supports this hypothesis.
Is this due to microRNA from the pathogen causing inhibition of defense genes?
