Quizplus · Accepted Answer

When a bacterium with a mutation in the avirulence gene lands on a plant with the corresponding R gene, it cannot elicit the rapid cell death response in the plant, leading to a successful infection. This is because the R gene triggers the plant's immune response if it recognizes the avirulence protein produced by the bacterium. But if the avirulence gene is mutated, the protein produced may not be recognized by the R gene, thus avoiding the immune response.
