| Several common weeds, including pigweed, lamb's quarters, and kochia, have been reported to be hosts for the pathogen. |
| If the pathogen causing reinfection is different from the original pathogen, two weeks of treatment are sufficient. |
| A gene from a human pathogen is inserted into a bacterium that infects plants. |
| Plants require dominant or semidominant resistance gene alleles to specifically recognize pathogen ingress. |
| Higher plants have developed several elaborate mechanisms to ward off pathogen attack. |
| One possible reason for the different functions encoded by R genes is the different modus operandi employed by different pathogen species. |
