Classical breeding techniques via introgression of resistance genes from wild species have been time-consuming and non-persistent. This calls for alternative methods that can be used in combination with existing strategies. Induced resistance is being explored as one of these. We and several others have shown that BABA (β-aminobutyric acid) and Phosphite (salts of phosphorous acid) induce resistance against the oomycete. However, a lot remains to be understood regarding the molecular aspects of induced resistance. We have performed quantitative transcriptomics and proteomics analysis of Phosphite and BABA treated plants to explore the mechanisms and pathways involved. A clear similarity in regulation was observed. In order to advance analysis, potato and arabidopsis protein sequences were linked by clustering predicted protein sequences from 18 plant genomes. Existing arabidopsis pathways were then repopulated using these links and expression data was overlaid to better explore changes observed after Phosphite and BABA treatment.
