- Scientists find missing link to understand how plants make vitamin C
04-27-2007 · EurekAlert!
Vitamin C is possibly the most important small molecule whose biosynthetic pathway remained a mystery. That is until now. A group of Dartmouth and UCLA researchers, who normally work on genes involved in aging and cancer in animals, discovered the last piece of the puzzle, they report in a study published online April 26 in the Journal of Biological Chemistry.

- Discovery in plants suggests entirely new approach to treating human cancers
04-04-2007 · EurekAlert!
For the first time, scientists from the University of Washington School of Medicine, Indiana University Bloomington and the University of Cambridge have determined how a plant hormone -- auxin -- interacts with its hormone receptor, called TIR1. Their report, on the cover of this week's issue of Nature, also may have important implications for the treatment of human disease, because TIR1 is similar to human enzymes that are known to be involved in cancer.

- Genetic differences in clover make one type toxic
10-01-2007 · EurekAlert!
That clover necklace you make for your child could well be a ring of poison. That's because some clovers have evolved genes that help the plant produce cyanide - to protect itself against little herbivores, such as snails, slugs and voles, that eat clover. Other clover plants that do not make cyanide are found in climates with colder temperatures. Kenneth Olsen, Ph.D., Washington University biologist is looking at the genetics behind this polymorphism.

- Got cotton? Texas researchers' discovery could yield protein to feed millions
11-20-2006 · EurekAlert!
Researchers at the Texas Agricultural Experiment Station used RNAi to reduce the toxic compound gossypol from cottonseed to a level that is considered safe for consumption, but left the compound in the rest of the plant to ward off insects and disease. Once commercialized, seed from these plants could provide a new, high-protein food available to 500 million people a year.

- Study shows vitamin C is essential for plant growth
09-23-2007 · EurekAlert!
Scientists from the University of Exeter and Shimane University in Japan have proved for the first time that vitamin C is essential for plant growth. This discovery could have implications for agriculture and for the production of vitamin C dietary supplements.

- World's largest flower evolved from family of much tinier blooms
01-11-2007 · EurekAlert!
The plant with the world's largest flower -- typically a full meter across, with a bud the size of a basketball -- evolved from a family of plants whose blossoms are nearly all tiny, botanists write this week in the journal Science. Their genetic analysis of rafflesia reveals that it is closely related to a family that includes poinsettias, the trees that produce natural rubber, castor oil plants and the tropical root crop cassava.

- Rapid evolution of defense genes in plants may produce hybrid incompatibility
07-08-2007 · EurekAlert!
Species are kept separate in plants and animals through barriers to gene flow. However, the exact mechanisms of speciation have only been explained within the last 20 years. Dr. Detlef Weigel and colleagues found that one mechanism, hybrid necrosis, is associated with a plant defense gene. Different forms of these rapidly evolving genes in parent plants can cause autoimmune responses leading to offspring inviability and may represent a molecular pathway to speciation unique to plants

- Researchers JAZ(zed) about plant resistance discovery
07-18-2007 · EurekAlert!
The mystery of how a major plant hormone works to defend plants against invaders has now been revealed, thanks to collaborative research efforts by Michigan State University and Washington State University. MSU scientists Sheng Yang He and Gregg Howe were part of two back-to-back discoveries that solved the mystery, described in the July 18 online issue of the journal Nature.
