Tenuazonic Acid-Triggered Cell Death Is the Essential Prerequisite for Alternaria alternata (Fr.) Keissler to Infect Successfully Host Ageratina adenophora

Cells, 2021
The necrotrophic fungus Alternaria alternata contains different pathotypes that produce different mycotoxins. The pathotype Ageratina adenophora secretes the non-host-selective toxin tenuazonic acid (TeA), which can cause necrosis in many plants ...

Special issue in honour of Prof. Reto J. Strasser - Effect of AtLFNR1 deficiency on chlorophyll a fluorescence rise kinetics OJIP of Arabidopsis

Photosynthetica, 2020
Leaf-type ferredoxin-NADP(H) oxidoreductase, encoded by AtLFNR1 gene in Arabidopsis, extensively exists in chloroplast stroma and thylakoids and is responsible for the reduction of NADP+ to NADPH in PSI.
