Abstract:
... Stilbene synthase is an inducible enzyme occurring in a small number of plants. The enzyme is amenable to analysis and biochemical studies only after the cells are subjected to induction. Cell suspension cultures of peanut react very selectively if elicited with biotic inducers. Just as intact peanut plants produce stilbene phytoalexins when attacked by fungi so also do sterile cultured cells when ...

Abstract:
... Leafspot diseases, caused by Cercospora arachidicola S. Hori (early leafspot) and Cercosporidium personatum (Berk, and Curt.) Deighton (late leafspot), are worldwide production problems on peanut (Arachis hypogaea L.). The extensive use of fungicides to control these diseases on susceptible cultivars is costly to growers. Developing leafspot resistant cultivars is a primary objective in many breed ...

Abstract:
... The genetic nature of resistance to early (Cercospora arachidicola Hod) and late [Cercosporidium personatum (Berk. & Curt.) Deighton] leafspot of peanut (Arachis hypogaea L.) is quantitative, making selection for resistance difficult in segregating populations. In many areas of peanut production, without fungicide application one or both diseases may significantly reduce yields. A study was conduc ...
