QUESTION 1 2 points Save Answer Plants have evolved many different responses to attacks from other organisms, one of which is both a localized response to pathogens, as well as a more systemic response. Place each of the following events in the order they occur, beginning with the introduction of an avirulent pathogen to the leaf of a plant. Not all choices will be used A A resistance (R) protein produced by the plant recognizes any effector protein in its environment. B. Methylsalicylic acid is converted into salicylic acid C. Systemic acquired resistance is activated D. (This is Step 7) Before cell death, cells release methylsalicylic acid which gets distributed throughout the plant E. Pathogen releases an Avr effector protein F. Pathogenesis related (PR) proteins are produced to protect against a diversity of pathogens G. Plant cells in the immediate vicinity of the infection are destroyed H. The hypersensitive response is activated I. A resistance (R) protein produced by the plant recognizes a specific Avr protein 10 J. The plant produces antimicrobial molecules, modifying cell walls to seal them of. K. The first of two signal transduction pathway is triggered. L. Pathogenesis related (PR) proteins are produced to protect against a specific pathogen M. A second signal transduction pathway is triggered QUESTION 2 1.5 points Saved

Explanation / Answer

Pathogens relase an AVR effector protein hypersensitive reponse is activated A resistance R protein is produced by the plant recognize the specific AVR protein Pathogens related protein are produced to protect agnaist diveristy of pathogens plants cells in the immedaite vicinity are destroyed systemic acqured resistance is activated methyl salicyclic acid is converted into salicyclic acid before cell death , cell relases the methyl salicyclic acid gets distributed throughou the plants .
