Researchers from Tokyo Metropolitan University have discovered that the fern Hymenasplenium murakami-hatanakae can become independent gametophytes, i.e., live for long periods without a ...

Auxin is a key coordinative signal required for many aspects of plant development and its levels are controlled by auxin metabolism and intercellular auxin transport. Here we find that a member of PIN ...

One of the most astonishing secrets in biology is this: every plant you see makes two different plants from the same genome. And, scientists recently reported, a single gene from an ancient, powerful ...
