In the course of phytotoxin research, pyrenocines A (85) and B (86), and pyrenochaetic acids A (87), B (88) and C (89), were isolated from the culture filtrate of Pyrenochaeta terrestris, causal fungus of onion pink root disease, Fig. 22 [62, 63]. After structural determination, chemical syntheses of these phytotoxins were attempted [64-66]. Alth-... 

T t has been reported that fungal cellulases are induced enzymes and that cellulose preparations induce cellulolytic activity while easily assimilable carbon sources give the best fungal growth but less production of enzyme activity (9,12, 14). For example, Horton and Keen (10) found that 7.5 X 10"3M D-glucose repressed the synthesis of cellulase to a basal level in Pyrenochaeta terrestris and suggested that cellulase synthesis was regulated by an induction-repression mechanism.

Pyrenochaeta terrestris, the causal agent of the onion pink root disease, induces a proliferation of host membrane prior to cellular disruption several cell layers in advance of the infection front (1). The pathogen produces a phytotoxin known as pyrenocine A (5- crotonyl-4-methoxy-6-methyl-2 pyrone) (2). We believe that pyrenocine A may be involved in this response and report some observations on the effects of pyrenocine A on limited aspects of plant lipid metabolism. 

Similar results are reported for incorporation of H- and C-labelled acetates into elsinochromes C and D (55) by Pyrenochaeta terrestris.Both the C-14 and C-16 methyls incorporate up to...
