The development of identical egg laying organs of two nematode species is regulated by different signaling pathways Changes in a short protein domain can alter a whole signaling network involved in organ development"“ this is the key result of a comparative study of the development of the egg laying organ in two species of nematodes. However, the outward appearance of the organ remains the same in both species. The study provides support for the theory of developmental systems drift...

According to researchers, sex gives worms the power to fight off parasites. The researchers found that worms forced to reproduce asexually succumbed to a bacterial infection and died. The team said the results are the most convincing evidence to date for a key theory in evolutionary biology. The theory said that sex evolved because it allows organisms to reshuffle their genes into new combinations to stay a step ahead of parasites. The team said that reproducing asexually means there is no...

(Ivanhoe Newswire) -- Scientists have discovered a new role for a biological pathway that not only signals the body's metabolic response to nutritional changes but also affects lifespan. The researchers conducted the study on Caenorhabditis elegans (nematodes). Dietary restriction is a way to extend lifespan and postpone age-related diseases in many species including yeast, worms, flies and rodents. However, researchers have been unclear about the molecular signals involved until this study....

Basic Yellow 1 profoundly extends lifespan in healthy nematodes, and slows Alzheimer's disease-like pathology in worms Basic Yellow 1, a dye used in neuroscience laboratories around the world to detect damaged protein in Alzheimer's disease, is a wonder drug for nematode worms. In a study appearing in the March 30, online edition of Nature, the dye, also known as Thioflavin T, (ThT) extended lifespan in healthy nematode worms by more than 50 percent and slowed the disease process in worms...

U.S. Department of Agriculture (USDA) scientists trying to help Florida growers find a replacement for methyl bromide are studying an alternative soil treatment that uses molasses as one of its ingredients. Researchers with USDA's Agricultural Research Service (ARS) are examining whether a cropping system that uses molasses to stimulate microbial activity could be used to replace the popular fumigant. They also are studying recently developed fumigants. The work, presented at the recent...

New research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) has shown that nematode worms have to trade-off resistance to different diseases, gaining resistance to one microbe at the expense of becoming more vulnerable to another. This finding, published in PLoS ONE today (2 March 2011), reveals that the worms, called C. elegans, have a much more complex immune system than was previously thought and shows how important such trade-offs are across the animal...

Scientists demonstrate that environmental lithium uptake promotes longevity Professor Dr. Michael Ristow's team along with Japanese colleagues from universities in Oita and Hiroshima have demonstrated by two independent approaches that even a low concentration of lithium leads to an increased life expectancy in humans as well as in a model organism, the roundworm Caenorhabditis elegans. The research team presents its results in the online edition of the scientific publication European Journal...

Nematodes, microscopic worms, are making engineers look twice at their ability to exhibit the "Cheerios effect" when they move in a collective motion. These parasites will actually stick together like Cheerios swimming in milk in a cereal bowl after a chance encounter "due to capillary force." This observation has made Virginia Tech engineers speculate about the possible impacts on the study of biolocomotion. Their work appears in the journal, Soft Matter, a publication of the Royal Society...

At least, in nematode worms Male worms plug females after copulation as a form of 'gift', rather than to prevent them from mating again, as had previously been thought. Researchers writing in BioMed Central's open access journal Frontiers in Zoology found that plugged females mated just as often and were just as attractive as those who were unplugged, and that plugging ultimately improved female fitness. Nadine Timmermeyer worked with a team of researchers from the University of Tuebingen,...

ROCHESTER, N.Y., July 9 /PRNewswire-USNewswire/ -- It has been a basic principle of evolution for more than a century that plants and animals can adapt genetically in ways that help them better survive and reproduce. Now, in a paper to be published in the journal Science, University of Rochester biologist John Jaenike and colleagues document a clear example of a new mechanism for evolution. In previous well documented cases of evolution, traits that increase an animal's ability to...

Golden Nematode, Globodera rostochiensis
2014-01-12 00:00:00

The Golden Nematode (Globodera rostochiensis), also known as the golden eelworm or yellow potato cyst nematode, is a species of plant pathogenic nematode originally stemming from the Andes Mountains of South America. It was first discovered in Germany in 1913, believed to have arrived in Europe with imported potatoes sometime in the 19th century. It was first discovered in the US in 1941, in Canada in the 60s, and in Mexico in the 70s. It has also been found throughout Asia, Africa and...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
