Phytophthora infestans RXLR effector Pi04089 perturbs diverse defense-related genes to suppress host immunity.

ABSTRACT:

Background

The oomycete pathogen secretes many effectors into host cells to manipulate host defenses. For the majority of effectors, the mechanisms related to how they alter the expression of host genes and reprogram defenses are not well understood. In order to investigate the molecular mechanisms governing the influence that the Phytophthora infestans RXLR effector Pi04089 has on host immunity, a comparative transcriptome analysis was conducted on Pi04089 stable transgenic and wild-type potato plants.

Results

Potato plants stably expressing Pi04089 were more susceptible to P. infestans. RNA-seq analysis revealed that 658 upregulated genes and 722 downregulated genes were characterized in Pi04089 transgenic lines. A large number of genes involved in the biological process,
