| Research Abstract |
Host-selective toxins (HSTs) are known to be secondary metabolites with toxicity towards distinct plant genotypes, but the role of the HST in insensitive plants is unknown. I found that mRNA levels of some defense-related genes in response to a strain of A. alternata that produces a host-selective toxin (HST) reached a maximum faster than in response to a non-HST strain of A. alternata on a HST-insensitive plant. In adition, I found a lot of novel defense-related genes in response to HST on HST-insensitive plant. These results indicate that HST might work as an elicitor to induce the defense response in HST-insensitive plants.
