		<description><![CDATA[Last time we had a taste of HOW plants tell time. But what, if any, are the adaptive advantages to plants for doing so? It has long been presumed that the ability to anticipate day/night cycles gives organisms a fitness advantage. For instance, this would allow plants to anticipate daylight and adjust their photosynthetic metabolism [...]]]></description>

		<description><![CDATA[How Do We Know Plants Can Tell Time? The daily opening and closing of flowers and the rhythmic leaf movement of some plants suggests, even to the casual observer, that plants have an internal clock. To more careful observers, such as Carl Linnaeus and Charles Darwin, the evidence was clear that plants can tell time. [...]]]></description>

But after hundreds of millions of years of pathogen attacks, plants are still here. So, they must have ways to get well after being sick.

		<description><![CDATA[What if the roots of flowering plants produced chemical signals that regulated the branching and thickening of their shoots, i.e., secondary growth? Chemical signals used by plants to regulate their development and physiology are called plant hormones. Very small amounts of these compounds, acting alone or in tandem, often elicit dramatic effects on plant development. [...]]]></description>
