Study Analyzes Potato-Pathogen ‘Arms Race’ After Irish Famine

In an examination of the genetic material found in historic potato leaves, North Carolina State University researchers reveal more about the tit-for-tat evolutionary changes occurring in both potato plants and the pathogen that caused the 1840s Irish potato famine. The…

Legume genetic discovery could improve crop growth

International scientists identified a genetic "off switch" in legumes that stops nitrogen fixation when soil nitrate levels are high. Removing this switch ensures continuous nitrogen fixation, boosting crop growth and reducing the need for synthetic fertilizers, benefiting agriculture and the…
