MicroRNA discovery could bolster crop traits

New clues about microRNAs may lead to better understanding how crops respond to droughts and other stressors.

A team of biologists at the University of Nebraska-Lincoln has discovered an important component plants need to make microRNAs -- tiny molecules critical in regulating gene expression.

Despite their vital role, microRNAs are not well understood. Uncovering new clues about how plant cells generate them is a step toward better understanding how crops respond to droughts and other stressors.

The team's findings were
