Dehydroipomeamarone as an Intermediate in the Biosynthesis of Ipomeamarone, a Phytoalexin from Sweet Potato Root Infected with Ceratocystis fimbriata.
Recently, we isolated dehydroipomeamarone, a new sesquiterpenoid from sweet potato (Ipomoea batatas Lam.) root tissue infected with Ceratocystis fimbriata (Ell. et Halst.). The purpose of this investigation was to determine whether dehydroipomeamarone was a precursor in the biosynthetic pathway of ipomeamarone. The incorporation of acetate-2-(14)C into ipomeamarone was markedly inhibited by the...
متن کاملIntersterility, morphology and taxonomy of Ceratocystis fimbriata on sweet potato, cacao and sycamore.
Ceratocystis fimbriata is a large, diverse complex of species that cause wilt-type diseases of many economically important plants. Previous studies have shown that isolates in three monophyletic lineages within the Latin American clade of C. fimbriata are host-specialized to cacao (Theobroma cacao), sweet potato (Ipomoea batatas) and sycamore (Platanus spp.), respectively. We paired testers of ...
متن کاملAnalytical study of ipomeamarone & chlorogenic acid alterations in sweet potato roots infected by Ceratocystis fimbriata.
Several metabolic alterations have been studied, from biochemical and pathological viewpoints, in sweet potato roots infected by the black rot fungus, Ceratocystis finbriata (2, 11, 13), among which the formation of ipomeamarone is of particular interest. Because this substance is a unique furanoterpenoid produced by host tissues in response to infection, and because it has remarkable biologica...
