WEST LAFAYETTE, Ind. - A study out of Harvard and Purdue universities is starting to unravel the genetic mechanisms that allow some plants to duplicate their entire genomes and continue to reproduce.

Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the ...

Researchers have used a unique microscopic technique to examine the dynamics of pollen tubes in the Arabidopsis plant. They were able to observe the mechanism of one-to-one pollen tube guidance, a ...

Most plants can reproduce both sexually (through flowers and seed) but many important crops, such as potatoes and strawberry, are propagated vegetatively, e.g. through tubers or shoots. A new study of ...

Take it from a seasoned hortifreak, plants can reproduce in weird ways. I’m not talking about unusual seeds, ranging from giant naked coconuts to those little bumps on the outside of strawberry fruit ...

What came first — the plant or the seed? Columnist Carol Barany explores how plants made the leap from water to land, why ...

When we think about plants and trees, we mostly focus on their beauty and the shade they provide. Plants are incredibly diverse when it comes to their reproductive strategies. Most plants have flowers ...

Hot desert sex has resulted in major genetic differences between male and female jojoba plants -- one of only 6 percent of plants that require a male and female plant to reproduce. New research ...
