This project aims were to provide new insights on the mechanisms activated during alkalinization and acidification of the infection court by Colletotrichum and Botrytis spp. respectively that will lead to quiescent infection-development on tomato fruits. We have chosen these pathogens due to their contrasting life style of alkalinization and acidification, respectively. We will study the roles of these fungal-based host-pH modulators in modulating host gene expression during quiescent infection development and compare these roles with those governing active colonization as a basis for developing novel strategies for control of postharvest diseases. The aims will be pursued through: Characterization of the effects of pH modulation on fungal-plant cell-cell signaling and on the fungal and plant transcriptome during the initial stages of fungal quiescence. The unpublished material that is presented as short abstract is considered one of the key point modulating Characterization of expression profiles of tomato fruits affected by acidifying and alkalinizing pathogensduring the transformation of quiescent to active infections by Colletotrichum and Botrytis. Functional analysis of selected genes involved in signaling pathways that affects the quiescent and active infections of Colletotrichum and Botrytis.
