These changes related to the SA-pathway genes in the susceptible genotypes might have (1) deteriorated the action of the JA-signaling pathway, (2) increased the cell death, and therefore, (3) facilitated successful infection by Fsp. Genetic mapping or gene knockouts are needed to evaluate the involvement of the SA-signaling pathway in the development of root rot disease caused by Fsp in the susceptible genotypes. Here, CXCL1 is linked to infection.
