Thale cress goes on the defensive

Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food. The plant hormone jasmonic acid plays a major role during the immune response against insects and pathogens. Dutch researcher Vivian van Oosten has demonstrated that this does not necessarily lead to the control of the same genes during the various interactions.

   05-09-2007 · EurekAlert!
   Rooted in place, plants can't run from herbivores -- but they can fight back. Sensing attack, plants frequently generate toxins, emit volatile chemicals to attract the pest's natural enemies, or launch other defensive tactics. Now, for the first time, researchers reporting in the June 2007 issue of Plant Physiology have identified a specific class of small peptide elicitors, or plant defense signals, that help plants react to insect attack.

   12-12-2007 · EurekAlert!
   When the alert goes out that a virus has invaded the body, cells that have yet to be attacked prepare by "armoring" themselves for combat, attaching specific antiviral molecules to many of their own proteins to help resist the invader. Unfortunately, the deadly Crimean Congo hemorrhagic fever virus knows a simple but devastating way around this defense: just cut the armor off host cell proteins.
