Diaporthe

Diaporthe is a genus of endophytic filamentous fungus plant pathogens. Diaporthe species have been shown to transform the infection-inhibiting factors (+)-catechin and (−)-epicatechin into the 3,4-cis-dihydroxyflavan derivatives Some species, like Diaporthe toxica, produce secondary metabolites that result in toxicoses of animals such as lupinosis of sheep.
