13. High-level expression of ice nuclei in a Pseudomonas syringae strain is induced by nutrient limitation and low temperature.
Attempts were made to maximize the expression of ice nuclei in Pseudomonas syringae T1 isolated from a tomato leaf. Nutritional starvation for nitrogen, phosphorous, sulfur, or iron but not carbon at 32 degrees C, coupled to a shift to 14 to 18 degrees C, led to the rapid induction of type 1 ice nuclei (i.e., ice nuclei active at temperatures warmer than -5
