Differential Expression of Pathogenesis Related Protein Genes in Tomato during Inoculation with A. Solani

To further increase our understanding of responses in tomato to early blight pathogen, we studied a microarray analysis using Affymetrix Tomato Gene chip array, representing approximately 10,000 genes. Our goal was to understand the pattern of expression of pathogenesis related proteins, which have important roles during interaction between host and pathogen. We found that total thirty two genes in this category showed significant changes in resistant and susceptible genotypes i.e. EC-520061 and CO-3. Amongst these thirty two genes, twenty genes were up regulated in case of resistant genotype whereas no significant up regulation in fold change (FC) was observed in case of the susceptible genotype. This study might be useful for further improvement of resistance in agronomically accepted tomato variety.
