Answer #1

Chitin receptors on the plasma membrane of plants are involved in the PAMP-triggered defense. Plants can recognize chitin which is generally released from the fungal cell walls. This recognition activates defense signalling pathway through pathogen-associated molecular pattern or PAMP.

R proteins or resistance proteins produced by plants activate effector-triggered immunity or ETI, not PAMP-triggered immunity. Effector protein is not involved in PAMP-triggered defense.

3. Which of the following statements is TRUE? The regulatory proteins produced by the MATa and MAT? alleles are identical and are found in all three yeast mating types. Unlike the MATa allele, the MAT? allele can actually produce two proteins, ?1 and ?2, which function as an activator and repressor, respectively. In yeast cells, the Mcm1 protein is encoded by the MATa allele and as such is only present in a cells. The MAT gene is the only gene...
