Sacred Lotus Genome May Hold Key To The Secrets Of Aging
2013-05-13 09:50:59

Lawrence LeBlond for redOrbit.com - Your Universe Online A team of international scientists report today that they have sequenced and annotated the genome of the sacred lotus (Nelumbo nucifera), which is thought to have a powerful genetic system. The team, which includes researchers from the US, China, Australia and Japan, have sequenced nearly 90 percent of the plant´s 27,000 genes. The sacred lotus, which is a symbol of spiritual purity and longevity, has the ability to repair...

Genome Sequencing Of The Sea Lamprey Completed By Researchers

Brett Smith for redOrbit.com - Your Universe Online According to a report in the journal Nature Genetics, an international team of geneticists has announced the successful sequencing of the sea lamprey genome. The sea lamprey makes for an interesting genetic case from an evolutionary standpoint, being a jawless vertebrate that diverged from jawed vertebrates millions of years ago. “The sea lamprey is a primitive jawless vertebrate that diverged from other jawed vertebrates...

Scientists have discovered a genetic cause of extreme thinness for the first time, in a study published today in the journal Nature. The research shows that people with extra copies of certain genes are much more likely to be very skinny. In one in 2000 people, part of chromosome 16 is duplicated, making men 23 times and women five times more likely to be underweight. Each person normally has a copy of each chromosome from each parent, so we have two copies of each gene. But sometimes...

Thanks to its flexible genome the plant can adapt to various environmental conditions People can develop new technologies and animals may migrate to other regions. However, plants are tied to their location. Nevertheless, they have found ways to ensure their survival. This is the case for the plant Arabidopsis thaliana, which is found throughout the entire northern hemisphere. But how does this small, inconspicuous plant deal with all these different extremes? In order to discover the...

Hybrid plants with multiple genome copies show evidence of preferential treatment of the genes from one ancient parent over the genes of the other parent, even to the point where some of the unfavored genes eventually are deleted. Brian Dilkes, an assistant professor of genetics at Purdue University, worked with a team of scientists at the University of California Davis and University of Southern California to study the genome of Arabidopsis suecica, a hybrid species with four chromosome sets...

US-German team measures how quickly genomes change Mutations are the raw material of evolution. Charles Darwin already recognized that evolution depends on heritable differences between individuals: those who are better adapted to the environment have better chances to pass on their genes to the next generation. A species can only evolve if the genome changes through new mutations, with the best new variants surviving the sieve of selection. Scientists at the Max Planck Institute for...

In a step that advances our ability to discern the ancient evolutionary relationships between different genes and their biological functions, researchers have provided insight into the present-day outcome of a single gene duplication that occurred over a hundred million years ago in an ancestor of modern plants. The work is reported in Current Biology by a team led by Brendan Davies of the University of Leeds, England. Gene duplication--a relatively uncommon event in which a single copy of a...
