Identification of phytotoxins from Botryosphaeria obtusa, a pathogen of black dead arm disease of grapevine [PDF]

open access: yes, 2009
A bioassay-guided fractionation of a culture filtrate of Botryosphaeria obtusa led to the isolation of four dihydroisocoumarins, named mellein 1, 4-hydroxymellein 2, 7- hydroxymellein 3 and the new 4,7-dihydroxymellein 4.

Arsenic Resistance Protein BcArs2 Modulates Endogenous ROS Homeostasis in Infection Cushions to Enhance the Virulence of Botrytis cinerea Toward Host Plants

open access: yesMolecular Plant Pathology, Volume 27, Issue 10, October 2026.
BcARS2 negatively regulates catalase gene expression and CAT activity, and positively regulates BcCGF1 to maintain intracellular H2O2 homeostasis. This mediates infection‑cushion development and facilitates toxin biosynthesis, ultimately governing the pathogenicity of Botrytis cinerea.

Removal of phytotoxins in filter sand used for drinking water treatment

open access: yes, 2021
Phytotoxins - toxins produced by plants – are contaminants with the potential to impair drinking water quality. They encompass a large group of toxic, partially persistent compounds that have been detected in seepage waters and in shallow wells used for ...

Untangling Dynamic Drivers of Salt Marsh Migration

open access: yesWater Resources Research, Volume 62, Issue 9, September 2026.
Abstract Coastal marsh transgression into upland ecosystems is driven by complex hydrological processes, stressing vegetation through root‐zone salinization and hypoxia, but interacting roles of these stressors remains poorly understood. We use high‐resolution field observations at six sites along the Delmarva Peninsula, USA, to better understand how ...

Cacao Rootstock Selection Resistant to Ceratocystis cacaofunesta at the INIAP Germplasm Collection, Ecuador

open access: yesPlant Pathology, Volume 75, Issue 5, September‐October 2026.
The genetic improvement programme, aimed at identifying cocoa rootstocks resistant to Ceratocystis cacaofunesta, has enabled the selection of a series of genotypes with high levels of resistance within the INIAP germplasm bank. The use of improved and certified material in the clonal propagation of plants guarantees the productive life of our cocoa ...
