Diaporthe toxica (anamorph Phomopsis sp. formerly P. leptostromiformis var. leptostromiformis)[1] is a lupin endophyte and occasionally a plant pathogen. The fungus produces secondary metabolites that result in toxicosis of animals such as lupinosis of sheep when infected lupins are ingested by animals. The fungus produces mycotoxins called phomopsins, which cause liver damage. Lupinosis has been incorrectly attributed to Diaporthe woodii but has now been shown to be a mycotoxicosis caused by the recently discovered (1994) teleomorphic fungus Diaporthe toxica.[2] The discovery and naming of this fungus concludes over a century of investigation into the cause of lupinosis since the first major outbreak in Germany in 1872. The infection process and life cycle in both resistant and susceptible lupins has been fully elucidated.[3] This is the first record of resistance in a latent infection. Following this research rapid molecular breeding techniques have been developed leading to the production of many resistant lupin varieties. Lupinosis is no longer considered a disease of major importance to livestock producers in Western Australia.[4] Lupins can now become part of the human diet.

Diaporthe toxica est une espèce de champignons ascomycètes de la famille des Diaporthaceae. Ce sont des champignons endophytes et occasionnellement pathogènes, dont les hôtes préférentiels sont les lupins, chez lesquels ces organismes peuvent infecter les tiges et les gousses, causant des pertes de rendement, mais aussi produire des phomopsines, mycotoxines hépatotoxiques, dangereuses pour le bétail. Diaporthe toxica est la forme asexuée (téléomorphe) de Phomopsis leptostromiformis (anamorphe).
