The first, moss-like plants emerged on land about 470 million years ago. In just 25 million years, they stripped the planet of vital minerals, wrecked Earth's carbon cycle, started an ice age, and caused a mass extinction of marine life.

"A desert mouse has found a seed. It bites into it, and gets a pungent mouthful of mustard. Reeling from the chemical party in its mouth, its spits out the seed and unwittingly helps the seed’s producer – a Israeli desert plant called Ochradenus baccatus. By using chemical weapons, it converts rodents into an unwitting vehicles for its seeds."

Study Finds Plants Flowering And Leafing Much Earlier Compared To Climate Models

Study Finds Plants Flowering And Leafing Much Earlier Compared To Climate Models | Botany teaching & cetera | Scoop.it

April 9, 2013 - Abut My Planet

Climate modeling has become an important method of attempting to determine the impacts of climate change in years to come. However, climate modeling is not without faults. Climate modeling is an evolving process which is refining along the way. A new study based on plants indicates that some significant tweaking is required for some climate models. Led by Dr. Elizabeth Wolkovich from the University of British Columbia, the study evaluated flowering and leafing plants for their blooming dates. Published in the journal Nature, the researchers determined that the current climate models are significantly lagging behind the real-time impacts of leafing and flowering plants... http://www.aboutmyplanet.com/environment/study-finds-plants-flowering-and-leafing-much-earlier-compared-to-climate-models/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+Aboutmyplanetcom+%28aboutMyPlanet.com%29

"This post looks at how surviving one bacterial attack can make plants more able to survive subsequent ones with both local and systemic acquired resistance.

 

Locally acquired resistance is the simplest to manage, and provides a clear advantage. If cells have been attacked once it makes sense to defend them in case of a second attack."
