Production of phleichrome by Cladosporium phlei as stimulated by diketopiperadines of Epichloe typhina.
Epichloe typhina is an endophytic fungus, while Cladosporium phlei is a pathogenic fungus of the timothy plant (Phleum pretense L.). We found two activities in the culture filtrate of E. typhina: one stimulated the pathogenic fungus, C. phlei, to produce phleichrome and the other inhibited its growth. The active ingredients that stimulated the production of phleichrome and inhibited the growth ...
متن کاملIdentification of a Polyketide Synthase Gene in the Synthesis of Phleichrome of the Phytopathogenic Fungus Cladosporium phlei
Phleichrome, a pigment produced by the phytopathogenic fungus Cladosporium phlei, is a fungal perylenequinone whose photodynamic activity has been studied intensively. To determine the biological function of phleichrome and to engineer a strain with enhanced production of phleichrome, we identified the gene responsible for the synthesis of phleichrome. Structural comparison of phleichrome with ...
متن کاملPhytotoxic Glycopeptide Produced by Corynebacterium sepedonicuml
A purified toxic glycopeptide from Corynebacterium sepedonicum (Speick.) Dows., possesses the capacity to wilt plant cuttings. The toxin induces a rapid g:neral flaccidity in stem tissues followed by a leaf wilt making its effects significantly different from that induced by high molecular weight substances (dextrans). In the latter case, the initial effect of -a dextran induced wilt is a leaf ...
متن کاملMaltophilin: a new antifungal compound produced by Stenotrophomonas maltophilia R3089.
Strains of Stenotrophomonas maltophilia R3089, isolated from the rhizosphere of rape plants (Brassica napus L.), produced a novel antifungal compound, named maltophilin, which inhibited the growth of various saprophytic, human-pathogenic and phytopathogenic fungi but was inactive against Gram-positive and Gram-negative bacteria. Maltophilin is a novel macrocyclic lactam antibiotic with a molecu...
متن کاملPhytotoxic components produced by pathogenic Fusarium against morning glory.
A pathogenic isolate of Fusarium, F. oxysporum f. sp. batatas O-17 (PF), causes wilt disease in leaf etiolation in sweet potato (Ipomoea batatas) and morning glory (Ipomoea tricolor). Extracts from PF cultures were screened for phytotoxic components using a growth inhibition assay with morning glory seedlings. The extracts were fractionated using differential solvent extraction and two active c...
