Effector-Mediated Suppression of Programmed Cell Death by Phytophthora palmivora in Oil Palm.

ABSTRACT: Phytophthora palmivora is the pathogen causing bud rot in oil palm (Elaeis guineensis). This pathogen secretes effector proteins that manipulate host defenses, contributing to disease progression. In this study, we systematically investigated the role of specific effector proteins in suppressing programmed cell death (PCD) in oil palm leaflets. Our approach included using genomic and transcriptomic data from a Colombian P. palmivora isolate alongside the coexpression network of a substantial effector dataset. From this analysis, ten candidate effectors were selected, characterized, and evaluated for their ability to suppress PCD in oil palm leaflets through transient expression via biolistics. Several effectors exhibited significant anti-PCD activity in susceptible and
