The table below represents plant disease resistance genes, the protein type and race-specific nature: Disease resistance
In the table below represents plant disease resistance, A-b-ii B-d-ii C-a-i and D-c-i represents established outcome. functional assays confirms option B (A-b-ii B-d-ii C-a-i and D-c-i) as correct, while alternatives misstate substrate or regulatory direction, contradicting textbook data.
