How does pathogen sense environment? Scientists identify key proteins’ structures

In order to adapt to the changing environment, bacteria must quickly transform extracellular information into appropriate intracellular reactions. Two component system (TCS) is the main signal transduction protein in prokaryotic cells to transform environmental stimuli into cellular responses. HptRSA is a newly discovered TCS, which is composed of glucose-6-phosphate (G6P) related sensor protein HptA, transmembrane […]

Cucurbit downy mildew pathogen has two genetically distinct host-adapted clades

Field work in North Carolina Credit: E. C. Wallace, K. N. D’Arcangelo, and L. M. Quesada-Ocampo Cucurbit downy mildew is a devastating disease for the United States cucurbit industry, which includes cucumbers, watermelon, squash, and pumpkin. The disease has caused major losses in North Carolina, which has significant cucumber and watermelon acreage. To help growers […]
