Researchers at the University of Delaware have provided what is believed to be the first experimental evidence that plants can take up nanoparticles and accumulate them in their tissues.

Even plants benefit from outsourcing

The answer to successful revegetation of native flora is in sourcing genetically diverse seed not necessarily relying on remnant local native vegetation to provide seed.

By themselves or as an ingredient in a variety of foods, including salsa, America's top-selling condiment, peppers have found a warm spot in the hearts and stomachs of U.S. consumers.

Effects of climate change vary greatly across plant families

Drawing on records dating back to the journals of Henry David Thoreau, scientists at Harvard University have found that different plant families near Walden Pond have borne the effects of climate change in strikingly different ways.

Pollen proteins that provide insight into the fertilization process

Without eyes or ears, plants must rely on the interaction of molecules to determine appropriate mating partners and avoid inbreeding. In a new study, University of Missouri researchers have identified pollen proteins that may contribute to the signaling processes that determine if a plant accepts or rejects individual pollen grains for reproduction.

Plants can signal microbial friends for help

Researchers at the University of Delaware have discovered that when the leaf of a plant is under attack by a pathogen, it can send out an S.O.S. to the roots for help, and the roots will respond by secreting an acid that brings beneficial bacteria to the rescue.

How plants fine tune their natural chemical defenses

Even closely related plants produce their own natural chemical cocktails, each set uniquely adapted to the individual plant's specific habitat.

Key to virulence protein entry into host cells discovered

Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have identified the region of a large family of virulence proteins in oomycete plant pathogens that enables the proteins to enter the cells of their hosts.

Plant steroids offer new paradigm for how hormones work

Steroids bulk up plants just as they do human athletes, but the playbook of molecular signals that tell the genes to boost growth and development in plant cells is far more complicated than in human and animal cells.

Milkweed's evolutionary approach to caterpillars

The adage that your enemies know your weaknesses best is especially true in the case of plants and predators that have co-evolved: As the predators evolve new strategies for attack, plants counter with their own unique defenses.
