Jan 5, 2022 · Under favorable conditions, resting spores are induced to germinate and release primary biflagellate zoospores, which are required for infection in the field. Thus, the regulation of resting spore germination is a crucial factor for the completion of the pathogen life cycle through infection and disease induction. Bacteria and plasmids used, growth, sporulation, and spore germination. The bacterial strains and plasmids used in this work are listed in Table Table1. 1.
