Recent studies have generated new insights into the mechanisms of pathogen entry into host cells and signal transduction, but very little is known about the bacterial effectors and cellular ...

To highlight the importance of these protein kinase families in the response to arthropod herbivores, a compilation of previous knowledge on their members is offered. When available, this information ...

But over the last decade or so, we’re now starting to see different companies bring together ectoparasite-control drugs as well as endoparasite-control drugs to create what they call an endectocide ...
