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

Following are the list of some of the molecular “danger signals” (column I) and its characteristics (column II)
| Column I | Column II |
| a) MAMPs | i) produce from the pathogen molecules support their ability to successfully colonize their host and gain nutritional benefits |
| b) DAMPs | ii) A plant response to insect herbivores involve both a wound response and the recognition of certain compounds abundant in the insect’s saliva or regurgitant |
| c) Effectors | iii) are conserved among a specific class of microorganisms such as chitin for fungi, flagella for bacteria |
| d) Elicitor | iv) molecules secrete from the damaging plant by herbivory such as Prosystemin |
Which of the following is the correct match between the signals and their respective mechanism?
