A gentler way in: scientists can finally read a plant's proteins without crushing the cell

A leaf keeps its proteins locked behind a tough cell wall, which is why studying plant health has lagged behind human biology. Researchers at the University of Delaware, led by proteomics director Yanbao Yu and postdoctoral researcher Deji Adekanye, have validated a way to digest and read those proteins inside intact plant cells, published in Plant Physiology. In plain terms: scientists can now spot the early protein signals of a sick crop — and one day help farmers treat it before the harvest is lost.
