The Army Within the Plant: Identifying Tomato Genes Involved in Mi-1-Mediated Defense
In plants, resistance (R) gene-mediated defense confers resistance to a specific pest or pathogen following recognition of their avirulence (Avr) effectors. R-Avr mediated resistance is often conferred by a hypersensitive response that results in localized cell death at the infection site which starves the pathogen or pest. Mi-1 is a tomato R gene that confers resistance to rootknot nematodes, ...
متن کاملTomato susceptibility to root-knot nematodes requires an intact jasmonic acid signaling pathway.
Responses of resistant (Mi-1/Mi-1) and susceptible (mi-1/ mi-1) tomato (Solanum lycopersicum) to root-knot nematodes (RKNs; Meloidogyne spp.) infection were monitored using cDNA microarrays, and the roles of salicylic acid (SA) and jasmonic acid (JA) defense signaling were evaluated in these interactions. Array analysis was used to compare transcript profiles in incompatible and compatible inte...
متن کاملEarly molecular signatures of responses of wheat to Zymoseptoria tritici in compatible and incompatible interactions
Zymoseptoria tritici, the causal agent of septoria tritici blotch, a serious foliar disease of wheat, is a necrotrophic pathogen that undergoes a long latent period. Emergence of insensitivity to fungicides, and pesticide reduction policies, mean there is a pressing need to understand septoria and control it through greater varietal resistance. Stb6 and Stb15, the most common qualitative resist...
متن کاملQuantitative nature of Arabidopsis responses during compatible and incompatible interactions with the bacterial pathogen Pseudomonas syringae.
We performed large-scale mRNA expression profiling using an Affymetrix GeneChip to study Arabidopsis responses to the bacterial pathogen Pseudomonas syringae. The interactions were compatible (virulent bacteria) or incompatible (avirulent bacteria), including a nonhost interaction and interactions mediated by two different avirulence gene-resistance (R) gene combinations. Approximately 2000 of ...
متن کاملMi-1-Mediated aphid resistance involves salicylic acid and mitogen-activated protein kinase signaling cascades.
The tomato Mi-1 gene confers resistance to root-knot nematodes (Meloidogyne spp.), potato aphids (Macrosiphum eluphorbiae), and whiteflies (Bemisia tabaci and B. tabaci biotype B). Resistance to potato aphid is developmentally regulated and is not associated with induction of a hypersensitive response. The NahG transgene that eliminates endogenous salicylic acid (SA) was used to test the role o...
