Proteinase inhibitor (PI) accumulation has been described as a plant defense response against insects and pathogens. The induction of Pis is known to be regulated by endogenous chemical factors including phytohormones. We ...

Ultraviolet B (UV-B) radiation, a very small fraction of the daylight spectrum, elicits changes in plant secondary metabolism that have large effects on plant-insect interactions. The signal transduction pathways that ...

Plants have sophisticated defense systems to protect their tissues against the attack of herbivorous organisms. Many of these defenses are orchestrated by the oxylipin jasmonate. A growing body of evidence indicates that ...
