Doing rice right
Traditional Thai hill farmers help preserve genetic diversity of rice
July 27,
2009 --
 |
| National Science Foundation |
Traditional rice cultivation methods practiced in the isolated hillside farms of Thailand are helping preserve the genetic diversity of rice, one of the world's most important food crops, according to a new study by researchers at Washington University in St. Louis and Chiang Mai University in Thailand.

'Nurture, sustain a culture of scientific innovation'
Obama names WUSTL biologist to his science advisory council
May 7,
2009 --
President Obama has appointed Barbara A. Schaal, Ph.D., the Mary-Dell Chilton Distinguished Professor of biology in Arts & Sciences at Washington University in St. Louis and vice president of the National Academy of Sciences, to the President's Council of Advisors on Science and Technology.

Discovery could lead to better rice yields
Technology identified could reduce the spread of rice virus
Feb. 10,
2009 --
|
| National Science Foundation |
Building on plant virus research started more than 20 years ago, a biologist at Washington University in St. Louis and his colleague at the Donald Danforth Plant Science Center in St. Louis have discovered a technology that reduces infection by the virus that causes Rice Tungro Disease, a serious limiting factor for rice production in Asia.

'Chips off the old block'
Plant polymerases IV and V are special forms of Polymerase II
Jan. 6,
2009 -- It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.

Researchers solve piece of large-scale gene silencing mystery
Opening the "X-files" of biology

| Pikaard |
A team led by Craig Pikaard, Ph.D., WUSTL professor of biology in Arts & Sciences, has made a breakthrough in understanding the phenomenon of nucleolar dominance, the silencing of an entire parental set of ribosomal RNA genes in a hybrid plant or animal. Since the machinery involved in nucleolar dominance is some of the same machinery that can go haywire in diseases such as cancer, Pikaard and his collaborators' research may have important implications for applied medical research.

Partnership reaching students on a national level
Research-based undergraduate course expands beyond WUSTL
Nov. 25,
2008 --
Washington University in St. Louis is in the spotlight for its pivotal role in the Genomics Education Partnership, a collaborative effort to provide research experience in genomics to undergraduate classrooms across the country. At the helm of this mission is Sarah C.R. Elgin, Ph.D., WUSTL professor of biology and professor of education in Arts & Sciences, as well as professor of biochemistry & molecular biophysics and professor of genetics in the School of Medicine.

New gene silencing pathway found in plants
Shedding light on the 'dark matter' of genetics
Nov. 14,
2008 --
Biologists at Washington University in St. Louis have made major headway in explaining a mechanism by which plant cells silence potentially harmful genes. A team led by Craig Pikaard, Ph.D., WUSTL professor of biology in Arts & Sciences, has published a paper this month in Cell, that explains how RNA polymerases work together to use the non-coding region of DNA to prevent destructive, virus-derived genes from being activated.

| Unicellular nitrogen-fixing cyanobacteria |
A team of researchers headed by biologists at Washington University in St. Louis has sequenced the genome of a unique bacterium that manages two disparate operations — photosynthesis and nitrogen fixation — in one little cell during two distinct cycles daily.

A biologist at Washington University in St. Louis is the mastermind behind a project that has led to an informative book, aimed at children but appealing to all ages, on an endangered species of ape. Ursula Goodenough, Ph.D., professor of biology in Arts & Sciences, is the driving force behind I'm Lucy, A Day in the Life of a Young Bonobo, written by Mathea Levine, Goodenough's daughter, and featuring the photographs of St. Louisan Marian Brickner. The book includes a convincing, impassioned Afterward by the famed primatologist Jane Goodall.

It takes two to tango
Researchers identify proteins that make up specialized ion channels
June 3,
2008 -- Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery.
