Hairpin turn: Micro-RNA plays role in wood formation

Hairpin turn: Micro-RNA plays role in wood formation, Phys.org, June 10.
For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key relationships that control the process.
