Genome Of The Coelacanth Sequenced
2013-04-18 05:26:08

April Flowers for redOrbit.com - Your Universe Online The genome of the coelacanth, a creature with an evolutionary history that is both enigmatic and illuminating, has been decoded by the Genome Center of the Broad Institute of MIT and Harvard, and analyzed by an international team of researchers. The findings of this study are published in the journal Nature. The coelacanth, a sea-cave dwelling, five-foot long fish with limb-like fins, was once thought to be extinct until a living...

An international team of researchers join forces to decode the genome of the once-thought-to-be-extinct African coelacanthSingapore, Apr 18, 2013 - (ACN Newswire) - An enigmatic prehistoric fish has brought scientists at A*STAR's Institute of Molecular and Cell Biology (IMCB) together with researchers from all over the world to crack its genomic code. Findings from the study are providing new insights into the evolutionary history of the African coelacanth (Figure 1)(1) and possible clues as...

Mitochondrial Genome Of Ancestral Flowering Plant Revealed By Tulip Tree
2013-04-15 11:24:04

BioMed Central The extraordinary level of conservation of the tulip tree (Liriodendron tulipifera) mitochondrial genome has redefined our interpretation of evolution of the angiosperms (flowering plants), finds research in biomed Central's open access journal BMC Biology. This beautiful 'molecular fossil' has a remarkably slow mutation rate meaning that its mitochondrial genome has remained largely unchanged since the dinosaurs were roaming the earth. Evolutionary studies make used of...

Researchers have been able to reconstruct the genome sequence of an outbreak strain of Shiga-toxigenic Escherichia coli (STEC) using metagenomics (the direct sequencing of DNA extracted from microbiologically complex samples), according to a study in the April 10 issue of JAMA, a Genomics theme issue. The findings highlight the potential of this approach to identify and characterize bacterial pathogens directly from clinical specimens without laboratory culture. "The outbreak of...

Twenty researchers – more than half of them Simon Fraser University graduates and/or faculty – could become eastern Canada´s knights in shining white lab coats. A paper detailing their newly created sequencing of the mountain pine beetle´s (MPB) genome will be gold in the hands of scientists trying to stem the beetle´s invasion into eastern forests. The journal Genome Biology has published the paper. “We know a lot about how beetle infestations can...

Unraveling The Bizarre Features Of The Turtle Genome
2013-03-28 07:05:03

Lawrence LeBlond for redOrbit.com - Your Universe Online The western painted turtle (Chrysemys picta bellii) is one of the most widespread species of turtle in North America. This creature is found in fresh, slow-moving waters from southern Canada to northern Mexico and from the Atlantic to the Pacific. And because this species has been widely studied, it only makes sense for researchers to sequence its genome, and that they´ve done. Publishing the work in this week´s Genome...

Mountain Pine Beetle Genome Sequenced
2013-03-27 15:42:48

BioMed Central The sequencing and assembly of the genome of the mountain pine beetle, Dendroctonus ponderosae, is published online this week in Genome Biology. The species is native to North America, where it is currently wreaking havoc in an area of forest ten times larger than previous outbreaks. This paper determines genes that may be involved in colonizing the trees, such as enzymes for degrading plant cell walls, and identifies potential sex chromosomes in the beetle. D. ponderosae...

Research suggests that complex interactions underlie the development of myopia in humans In the largest ever genome-wide association study on myopia, 23andMe, the leading personal genetics company, identified 20 new genetic associations for myopia, or nearsightedness. The company also replicated two known associations in the study, which was specific to individuals of European ancestry. The study included an analysis of genetic data and survey responses from more than 50,000 23andMe...

In a collaborative study published online today in Nature Communications, researchers from Institute of Genetics and Developmental Biology, Chinese Academy of Sciences, BGI-Shenzhen, and University of Arizona have completed the genome sequencing of wild rice Oryza brachyantha. This work provides new insights for researchers to understand the function and evolution of Oryza genomes. The genus Oryza is an idea model system for studying plant comparative genomics, evolutionary biology and...

DNA Sequencing Used to Learn The History Of Native Snakes
2013-03-13 09:38:42

George Washington University Alex Pyron´s expertise is in family trees. Who is related to whom, who begat whom, how did they get where they are now. But not for humans: reptiles. In 2011, his fieldwork in Sri Lanka studying snake diversity on the island led him to confirm the identity of 60 known species of snakes. With Sri Lankan collaborators, Ruchira Somaweera, an author on snakes and expert on amphibians and reptiles, and Dushantha Kandambi, a local naturalist and snake expert,...

Northern Greater Galago, Otolemur garnettii
2012-05-29 12:39:27

The northern greater galago (Otolemur garnettii), also called Garnett's greater galago, is native to Africa. This species is important to genetic research because of the low genomic sequence, completed in 2006, that makes it possible to bridge the genome sequence of higher primates like chimps, and non-primate species like rodents. However, the small 2x genome is not large enough to be a complete genome. The northern greater galago has been given a conservation status of “Least Concern”...

Coccolithovirus, a giant double-stranded DNA virus, infects Emiliania huxleyi, a species of coccolithophore. The virus was first observed in 1999 by W.H. Wilson and his team at the Marine Biological Association. It was sequenced for the EhV-86 strain during the summer of 2005, and was found to be a "giant-virus" having 472 protein-coding genes. It is the largest known marine virus by genome.

toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
