Some given facts regarding effector molecules such as;
a) HC-toxin-induced plasma membrane hyperpolarization in guard cells causes massive K+ uptake and permanent stomatal opening
b) Xanthomonas, are proteins that target the plant cell nucleus and causes change in gene expression, called transcription activator-like (TAL) effectors bind to the host plant DNA and activate the expression of genes
c) Fusicoccin, a cyclic peptide, acts on the enzyme histone deacetylase in the nucleus, and may have a compromising effect on the expression of genes involved in defense
d) Gibberellins accelerate growth, resulting in bigger plants when compared with uninfested plants. The gibberellins produced by the fungi are identical to those produced endogenously by the plant
