To obtain an overall view on transcript modification during the cherry tomato fruit responding to biocontrol yeast Cryptococcus laurentii, we performed a microarrary analysis, using Affymetrix Tomato Genechip arrays, representing approximately 10,000 genes. The results showed that 194 and 312 genes were up- or down-regulated, respectively, more then ten time fold (log2 change ratio ≥ 2 or log2 change ratio ≤ − 2) in biocontrol yeast treated tomato fruit as compared with control fruits. Those up-regulated included genes involved in metabolism, signal transduction, and stress response. Conversely, genes related to energy metabolism and photosynthesis were generally down-regulated. Our results suggest that biocontrol yeast treatment induces fruit resistance response, suppresses energy metabolism and photosynthesis. A number of transcripts encoding proteins/enzymes which are known to be up-regulated under some biotic and abiotic stress are also up-regulated after the applying biological control yeast to cherry tomato fruit. The expression of these proteins might increase the fruit resistance towards postharvest pathogen infection and damage.
