Transcriptome responses to Ralstonia solanacearum infection in tetraploid potato.

ABSTRACT: Potato (Solanum tuberosum) is an important global food source, the growth of which can be severely impacted by Ralstonia solanacearum bacterial infection. Despite extensive research, the molecular mechanisms of potato resistance to this pathogen are imperfectly known. Huashu No. 12, a tetraploid potato genotype, is highly resistant to R. solanacearum. We inoculate Huashu No. 12 and Longshu No. 7 (highly susceptible to R. solanacearum) with R. solanacearum to compare disease resistance in these two potato varieties. Huashu No. 12 has significantly higher resistance to R. solanacearum infection than Longshu No. 7, with increased lignin content, and an abundance of callose and strong autofluorescence in the phloem sieve tube. Enzymes (e.g., superoxide
