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

Suppose you attend a town meeting at which some experts tell the audience that they have performed a cost-benefit analysis of a proposed transit system that would probably reduce overall air pollution and fossil fuel consumption. The analysis, however, reveals that ticket prices will not cover the cost of operating the system when fuel, wages, and equipment are taken into account. As a biologist, you know that if ecosystem services had been included in the analysis, the experts might have arrived at a different answer. Why are ecosystem services rarely included in economic analyses?
