Synthesis of (12R,13S)-pyriculariol and (12R,13S)-dihydropyriculariol revealed that the rice blast fungus, Pyricularia oryzae, produces these phytotoxins as racemates [PDF]

, 2021
Synthesis of assumed natural (12R,13S)-enantiomers of pyriculariol (1) and dihydropyriculariol (2), phytotoxins isolated from rice blast disease fungus, Pyricularia oryzae, was achieved using Wittig reaction or microwave-assisted Stille coupling reaction

Phytotoxins produced by Lasiodiplodia laeliocattleyae involved in Botryosphaeria dieback of grapevines in Brazil

Phytopathologia Mediterranea, 2019
Botryosphaeria dieback (BD) is an important trunk disease affecting grapevines. Several Lasiodiplodia species have been shown to be involved in BD affecting the perennial organs of grapevine, mainly causing cankers.

Shellfish culture in estuary zones and the sanitary restrictions [PDF]

Scientific Annals of the Danube Delta Institute, 2007
The nutritional requirements of shellfish are satisfied by the phytoplankton and the nutrients of the estuary waters. Bivalves (mussels, oysters, clams, cockles, scallops and razors) can be there produced.

Fungal phytotoxins with potential herbicidal activity: chemical and biological characterization

, 2015
Fungal phytotoxins are secondary metabolites playing an important role in the induction of disease symptoms interfering with host plant physiological processes. Although fungal pathogens represent a heavy constraint for agrarian production and for forest

Rice sheath rot: an emerging ubiquitous destructive disease complex

Frontiers in Plant Science, 2015
Around one century ago, a rice disease characterized mainly by rotting of sheaths was reported in Taiwan. The causal agent was identified as Acrocylindrium oryzae, later known as Sarocladium oryzae.

Potential New Herbicides – Phytotoxins from Plant Pathogens

, 1988
A rationale for the study of phytotoxins from fungal pathogens of plants is presented. Structural chemistries and biological data are given for numerous, recently discovered phytotoxins in such diverse chemical classes as polyketides, terpenoids ...
