Novel Resorcinol Derivatives from Lasiodiplodia theobromae
Two novel resorcinol derivatives were isolated from the mycelium of Lasiodiplodia theo bromae IFO 31059 as potato micro-tuber inducing compounds. Their structures were estab lished by spectroscopic methods as ethyl (6 ' 7?)-2,4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (8) and isobutyl (6 ' /?)-2.4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (9). The absolute stereo chemistry of the asymmetric cente...
متن کاملLasiodiplodia theobromae is a Mycoparasite of a Powdery Mildew Pathogen
Powdery mildews on over 40 plants in Bangalore were screened during July-December of 2003~2008. Isolates from mycoparasitised Oidium caesalpiniacearum of Bauhinia purpurea comprised Lasiodiplodia theobromae, in addition to Ampelomyces quisqualis. Koch's postulates were satisfied to establish the mycoparasitism of L. theobromae. This is the first report that L. theobromae acts as a mycoparasite ...
متن کاملData from proteome analysis of Lasiodiplodia theobromae (Botryosphaeriaceae)
Trunk disease fungi are a global problem affecting many economically important fruiting trees. The Botryosphaeriaceae are a family of trunk disease fungi that require detailed biochemical characterization in order to gain insight into their pathogenicity. The application of a modified Folch extraction to protein extraction from the Botryosphaeriaceae Lasiodiplodia theobromae generated an unprec...
متن کاملNovel Cyclohexene Compound from Lasiodiplodia theobromae IFO 31059.
A novel cyclohexene compound (1), which is structurally related to theobroxide (2), was isolated from a culture filtrate of the fungus, Lasiodiplodia theobromae IFO 31059. The potato micro-tuber-inducing activity of this compound was observed at a concentration of 10(-3) M in the medium, whereas theobroxide (2) showed its activity at 10(-5) M.
