Interpretive Summary:

Technical Abstract: In their interactions with microorganisms, higher plants encounter both beneficial and deleterious relationships. The response of plants to deleterious interactions such as disease has been a major area of plant science research during the past several decades. In order to invade plant tissues, attacking microorganisms must first penetrate surface layers, most of which possess physical barriers such as waxy cuticles and lignified/suberized cells. If the microorganism(s) are able to overcome these physical barriers, however, only chemical barriers produced by the plant prevent further infection. Chemical barriers include both pre-infectional, constitutive compounds and post-infectional, pathogen-induced compounds, representing many different chemical classes. Both constitutive and induced compounds, their respective chemical classes, and their potential uses in agriculture will be discussed.
