Female mate choice enhances offspring fitness in an annual herb
In many organisms females directly or indirectly select mates (or sperm) and potentially influence the fitness of their offspring. Mate choice and sexual selection in plants is more complex in some ways than in animals because plants are sessile organisms and often have to rely on external vectors, such as animals, for pollen transport. View News Article (2011-06-28)

Forensic botany uses plant DNA to trace crimes
Sam Houston State University is advancing the field of forensic botany with the publication of two recent studies that use marijuana DNA to link drug supplies and pollen DNA to aid in forensic investigations. View News Article (2016-03-01)

How plants sense gravity -- a new look at the roles of genetics and the cytoskeleton
Gravity affects the ecology and evolution of every living organism. In plants, the general response to gravity is well known: their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight. View News Article (2013-02-05)

Small but not forgotten: New ideas on pollen's ecology and evolution
Pollen grains may be small but they have a big job. Delivering a sperm to an egg is a little more complicated when the parents don't move around.  View News Article (2016-04-05)

Just what makes that little old ant- change a flower's nectar content?
Ants play a variety of important roles in many ecosystems. As frequent visitors to flowers, they can benefit plants in their role as pollinators when they forage on sugar-rich nectar. View News Article (2013-04-25)

Family matters: Evolutionary relationships among species of 'magic' mushrooms shed new light on fungi
"Magic" mushrooms are well known for their hallucinogenic properties. Until now, less has been known about their evolutionary development and how they should be classified in the fungal Tree of Life. View News Article (2013-08-07)

Scientists join forces to bring plant movement to light
Elementary school students often learn that plants grow toward the light. This seems straightforward, but in reality, the genes and pathways that allow plants to grow and move in response to their environment are not fully understood. View News Article (2013-01-03)

Pearl-flowered legume a surprise new find in the Cape Snowy Mountains, South Africa
A pearl-flowered legume collected in 2005 by Ralph Clark & Nigel Barker (Rhodes University) in the Sneeuberg, South Africa, was determined by taxonomists Charles Stirton & Muthama Muasya (University of Cape Town) to be a distinct new species.  View News Article (2011-07-28)

From one cell to many: How did multicellularity evolve?
In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. View News Article (2014-01-27)

Gene guards grain-producing grasses so people and animals can eat
Purdue University and USDA-Agricultural Research Service scientists have discovered that a type of gene in grain-producing plants halts infection by a disease-causing fungus that can destroy crops vital for human food supplies. View News Article (2008-02-04)
