Plants are continuously infected by various pathogens throughout their lifecycle. Previous studies have reported that the expression of Class III acyl-CoA-binding proteins (ACBPs) such as the Arabidopsis ACBP3 and rice ACBP5 were induced by pathogen infection. Transgenic Arabidopsis AtACBP3-overexpressors (AtACBP3-OEs) displayed enhanced protection against the bacterial biotroph, Pseudomonas syringae, although they became susceptible to the fungal necrotroph Botrytis cinerea. A Class III ACBP from a monocot, rice (Oryza sativa) OsACBP5 was overexpressed in the dicot Arabidopsis. The resultant transgenic Arabidopsis lines conferred resistance not only to the bacterial biotroph P. syringae but..
