Role of Millets for Food Security Under Climate Change. [PDF]

Plant Environ Interact
ABSTRACT The accelerating impacts of climate change pose significant threats to global food security, highlighting critical vulnerabilities within the agricultural system. As greenhouse gas emissions continue to rise, global temperatures have increased by 0.6°C over the 20th century, with projections indicating further increases of 0.1°C–2°C per decade.

Covariation of Ergot Severity and Alkaloid Content Measured by HPLC and One ELISA Method in Inoculated Winter Rye across Three Isolates and Three European Countries

Toxins, 2020
Ergot caused by Claviceps purpurea is a problem for food and feed security in rye due to the occurrence of toxic ergot alkaloids (EAs). For grain elevators and breeders, a quick, easy-to-handle, and cheap screening assay would have a high economic impact.
