TL;DR: This work has identified WVa700 as a tomato cultivar that can restrict S. enterica survival in the phyllosphere, and found that plants irrigated with contaminated water had larger S. enteringica populations than plants grown from seeds planted in infested soil.

TL;DR: The effects of the RB transgene on foliar late blight resistance in transgenic cultivated potato under field production conditions are examined and suggest resistance-gene transcript levels may have to surpass a threshold before triggering RNA silencing.

TL;DR: A major late blight resistance gene, called RB, previously was identified in the wild potato species Solanum bulbocastanum through map-based cloning has been integrated into cultivated potato (S. tuberosum) using Agrobacterium-mediated transformation but no significant effect on tuber size or yield was detected.

TL;DR: This study shows that silencing of the Sgt1 gene in potato does not result in lethality, however, the sergeant1 gene is essential for the RB-mediated late blight resistance, in contrast to the Rar1 gene, which is not required for RB- mediated resistance.

TL;DR: Transcription of the RB gene, which was cloned from the wild potato species Solanum bulbocastanum and confers resistance to potato late blight, was significantly increased after inoculation with the late blight pathogen Phytophthora infestans.
