DURHAM, N.C. -- Living things from bacteria to plants to humans must constantly adjust the chemical soup of proteins -- the workhorse molecules of life -- inside their cells to adapt to stress or changing conditions, such as when nutrients are scarce, or when a pathogen attacks. Now, researchers have identified a previously unknown molecular mechanism that helps explain how they do it. Studying a spindly plant called Arabidopsis thaliana, a Duke University-led team discovered short snippets of folded RNA that, under normal conditions, keep levels of defense proteins low to avoid harming the plants themselves.
