Differential expression analysis by cDNA-AFLP of Saccharum spp. after inoculation with the host pathogen Sporisorium scitamineum.

A differential expression study on the Saccharum spp.-Sporisorium scitamineum pathogenic interaction was carried out in the susceptible Ja60-5 and the resistant M31/45 genotypes. Using cDNA-AFLP analysis, a total of 64 transcript-derived fragments (TDFs) was found to be differentially expressed, with the majority (67.

Exogenous systemin has a contrasting effect on disease resistance in mycorrhizal tomato (Solanum lycopersicum) plants infected with necrotrophic or hemibiotrophic pathogens.

A study was performed to determine the effect of the systemin polypeptide on the bio-protective effect of arbuscular mycorrhizal fungi (AMF) in tomato plants infected with Alternaria solani, Phytophthora infestans or P. parasitica. Before infection, tomato plants were colonized with two different AMF, Glomus fasciculatum or G.
