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 ...

Jasmonates (JAs), a type of phytohormone, are involved in sensing and signaling of several environmental stresses (biotic and abiotic). Jasmonic acid (JA) has been suggested to function in plant responses to drought, because ...

The most studied mechanism of protection against herbivores in grasses associated with Epichloë fungal endophytes has been the fungal production of alkaloids. However, the contribution of the plant immune response on the ...
