N&H TOPLINE: Plant scientists untangle plant stress, growth

Autophagy plays important role in animal and plant growth in response to stress and could have implications for human health.

Iowa State University researchers, for the first time, have mapped the various molecular components that govern how environmentally stressed plants interrupt their normal growth pathways by tapping into an important energy recycling function.

The research, published in the peer-reviewed academic journal Developmental Cell, shows that autophagy, a system by which both plants and animals recycle energy and molecular components, plays a key role in slowing plant growth during ti
