Tomato fruit wound inoculation by C. coccodes and ammonium treated

ABSTRACT: Colletotrichum coccodes secretes ammonium during germination and colonization of host tissue as a mechanism for dual activation of fungal pathogenicity factors and plant cell death via activation of host NADPH oxidase. Ammonium accumulation during colonization of tomato fruits by C. coccodes induced host nucleus integrity changes and program cell death (PCD). Transcriptome analysis at the leading edge of colonized tissue and ammonium treated tomato fruits revealed 82 and 237 common up-regulated and common down-regulated genes, respectively. The common-up-regulated genes showed over representation of pathogen related (PR) proteins, salicylic acid (SA) dependent and systemic acquired resistance (SAR) related genes and genes related to biotic stress. The down regulated genes showed over repre
