Just as you suspected: research shows a lot of things that taste bad are good for you

Brussels sprouts, grapefruit, cabbage, kale, mustard greens, arugula, spinach, dark chocolates, red wine and a lot of other typical Thanksgiving leftovers are proven to contain dietary phytonutrients. These nutrients have been associated with cancer prevention and other health benefits. As a review by ...

New discovery: 'footprint' shows master switch simultaneously controls plants' disease defenses

...gy." Working with Arabidopsis, a member of the mustard family widely considered the "laboratory mouse" of the plant kingdom, the scientists analyzed expression of about 8,000 plant genes and tested them under 14 different conditions that either turned on or turned off the plant'simmune system. New genomi...

Voyage of the space veggies

...s a list of plants it thinks could one day cut the mustard in space (see Table). Given NASA's current priorities, Mars seems the likeliest first destination for bionic plants. Probably not on the first crewed missions-at three years or so, these would be short enough to take along everything the travellers ...

First-ever complete plant genome sequence is announced

...rs sequenced the entire genome of this weed in the mustard family. Because it is a model for over 250,000 other plant species, Arabidopsis is yielding insights that scientists are already applying to make other plants easier to grow under adverse conditions and healthier to eat. The AGI's internatio...

Scientists report first complete genome sequence of a plant

...Despite its status as a diminutive relative of the mustard plant, Arabidopsis thaliana is a powerful tool in plant molecular biology and genetics. The short generation time and relatively compact genome of Arabidopsis (a flowering plant) make it an ideal model system for understanding numerous features of pl...

First plant genome completed

...pact genome, Arabidopsis thaliana, a member of the mustard plant family, has become the primary model for the study of flowering plants in laboratories around the world. In 1996, an international collaboration, the Arabidopsis Genome Initiative, was formed to sequence and analyze the genome of this model pla...

Ancient origins found in arabidopsis genome

A weedy, inedible member of the mustard family, related to broccoli and cauliflower, has become the first plant to yield the secrets of its primordial origins. In a computational research effort at Cornell University, the plant, Arabidopsis thaliana, was shown to contain genetic eviden...

Biological warfare: an emerging threat in the 21st century

...nal revulsion over the widespread use of poisonous mustard gas during World War I that finally led to a 1925 treaty banning bioweapons during future wars. ``Disappointingly,`` Block writes, ``neither the U.S. nor Japan ratified the treaty before the advent of World War II, when anthrax and other bioweapons w...

Enzyme is crucial for production of plant growth hormone

... a small flowering plant that is a relative of the mustard plant, is the basic model organism used in plant biology research. "We were randomly inserting into the Arabidopsis genome DNA sequences called enhancer sequences that promote gene activity," said Chory, who is at The Salk Institute for Biological...

UCSD biologist transform leaves into petals

... the UCSD biologists report that they found in the mustard plant, Arabidopsis, that two of the SEP genes, in combination with three other genes responsible for floral development, are "sufficient to convert leaves into petals." The three other genes are part of complex known to specify the development of sep...

Genome project opens the book on human evolution

...rse as Drosophila (fruit flies) and Arabidopsis (a mustard plant) average10 percent. In addition, they were able to look at the location of these elements. These repetitive elements, particularly the element known as Alu, were found in a surprising number of proteins. "We have always assumed that insertion...

Zebrafish could become genetics 'lab rat' of choice

...he past decade, plant scientists have used a small mustard plant, called Arabadopisis, to conduct gene knockout experiments in crops and plants. But until now it has been difficult to conduct knockout experiments in animals. In mice until now the only animal in which the gene knockout technique works a gen...

Rockefeller researchers identify defense system in plants

...e paper. Arabidopsis, a well-studied weed in the mustard family, is a model system for the study of plant development because of a number of factors, including its small size and rapid generation time. Lopez-Molina and Sebastien Mongrand, Ph.D., both postdoctoral fellows at Rockefeller show that ABAa pla...

More extensive analysis casts doubt on portion of the public project's human genome paper

...e similarity to proteins from yeast, worm, fly and mustard weed" Based on this evidence, the earlier study concluded that these genes were likely transferred directly from bacteria into an ancestral vertebrate species. TIGR scientists reanalyzed the 31,780 genes that were the focus of the IHGSC report, and ...

New U. of Colorado research may reduce renewable fuel costs

Raised in closed chambers set at temperatures of roughly 77 degrees Fahrenheit for optimal growth, the plants manufacture significantly large quantities of the cellulase enzyme, which then is harvested from the ...

Global consortium announces plans to sequence banana genome

Scientists will map the banana genome using a sexually reproducing wild species of banana from Southeast Asia. "Banana will be th...

Genetic secrets of metal-eating plants uncovered

...nts." The genes were identified from the tiny wild mustard Thlaspi goesingense, a plant that lives in the Austrian Alps, where it hyperaccumulates nickel. The plant is similar to the nonmetal-accumulating plant Arabidopsis thaliana, which is commonly used in scientific research. The research is published in ...

Complex carbohydrate found to regulate plant growth

... mutant of Arabidopsis - a relative of cabbage and mustard - had normal amounts of RG-II in its cell walls but only half of the RG-II was cross-linked by boron. "Without that cross-linking, the cell walls apparently don't have the strength to expand normally and the plant is dwarfed," he said. Since the Ara...
