RNA seq analysis of pathogen-induced transcriptome changes in tomato plants overexpressing the Arabidopsis ELP4 gene. Solanum lycopersicum cultivar:Moneymaker

The goal of the RNA seq was to investigate the transcriptome changes induced by Pseudmonas syringae pv. tomato J4 in wild-type tomato 'Moneymaker' and transgenic 'Moneymaker' overexpressing the Arabidopsis ELP4 (AtELP4) gene. Results showed that P. syringae pv. tomato J4 induced dramatic transcriptional changes in bot the wild-type and transgenic tomato plants. Interestingly, a group of defense genes including PR-5x, Pti5, PR1b1, and CHI3/9/14/17, which are associated with resistance to the hemibiotrophic bacterial pathogen Ralstonia solanacearum, were induced to higher levels in the AtELP4 transgenic tomato than in the wild type at 8 and 24 hr after P. syringae pv. tomato J4 infection. These results indicate that overexpression of AtELP4 in tomato leads to faster and/or stronger induction of some defense genes.
