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

Stage thymocytes express neither CD4 nor CD8, markers associated with mature T cells. They are therefore called double negative (DN) cells. DN cells first travel to the region under the thymic capsule, a region referred to as the ________, where they proliferate and begin to generate their T-cell receptors. Thymocytes that successfully express TCRs begin to express both CD4 and CD8, becoming double positive (DP) cells, and populate the cortex, the site where most (85% or more) immature T cells are found.
