(AGS AGS American Geriatrics Society. ) in Oakland, Calif., sprayed a test plot of strawberry plants in a nearby town with Pseudomonas syringae Pseudomonas syringae is a rod shaped, Gram-negative bacterium, with polar flagella. It is a member of the Pseudomonas genus, and based on 16S rRNA analysis, P. syringae has been placed in the P. syringae group[1]. , which had been changed to retard ice crystal formation (SN: 5/2/87, p.277). Scientists say that data from the test, completed last week, show the bacteria were not found outside the test area--a possibility that has stirred controversy --which will be monitored for at least three months. Also, the P. syringae lowered the freezing temperature of the plants an average of 2|. Some plants had been subjected to freezing temperatures in a laboratory. |
