Platypus genome unravels mysteries of mammalian evolution

Genome Research is publishing several papers related to analyses of the duck-billed platypus (Ornithorhynchus anatinus) genome sequence. The place of (egg-laying) monotremes, such as the platypus, in mammalian evolutionary history has remained controversial. Now, researchers are finding that the distinctive anatomical and physiological properties of the platypus are reflected in the newly sequenced platypus genome. Through comparative genomics, the platypus genome is providing remarkable insights into the evolution of venom components, the sex-determination system, testicular descent, and small RNA pathways. Primary research reports describing these novel insights will appear online May 8, concurrent with publication of the platypus genome sequence report in the journal Nature.

Platypus Genome Explains Animal's Peculiar Features; Holds Clues To Evolution Of Mammals

An international consortium of scientists, led by Washington University School of Medicine in St. Louis, has decoded the genome of the platypus, showing that the animal's peculiar mix of features is reflected in its DNA. An analysis of the genome, published today in the journal Nature, can help scientists piece together a more complete picture of the evolution of all mammals, including humans.

First Draft of Oil Palm Genome Completed by Synthetic Genomics Inc and Asiatic Centre for Genome Technology

KUALA LUMPUR, Malaysia and LA JOLLA, Calif., May 21 /PRNewswire/ -- Asiatic Centre for Genome Technology Sdn Bhd (ACGT), which is focused on the commercial application of genome technology to improve oil palm and other crops and Synthetic Genomics Inc. (SGI), a privately held company dedicated to commercializing genomic-driven solutions to address global energy and environmental challenges, today announced the completion of a first draft assembly and annotation of the oil palm genome. The organizations also announced that they have made progress in sequencing and analyzing the jatropha genome. The oil palm and jatropha genome projects represent the first stages of research undertaken through a joint venture between SGI and ACGT which was announced in 2007 and is aimed at developing more high-yielding and disease-resistant plant feedstocks

Evolution Of An Imprinted Domain In Mammals

The normal human genome contains 46 chromosomes: 23 from the mother and 23 from the father. Thus, you have two copies of every gene (excluding some irregularity in the pair of sex chromosomes). In general, which parent contributes a chromosome has no effect on the expression of the genes found on it. Exceptions to this rule are caused by "genomic imprinting"--modification of DNA, which means that gene expression is influenced by which parent the gene came from. A new paper investigates the evolution of genomic imprinting in a specific region of the mammalian genome. The work, by Anne Ferguson-Smith and colleagues in the UK and Australia, shows that different regions became imprinted at different times during mammalian evolution.

Duck-Billed Platypus Genome Sequence Published

The first analysis of the genome sequence of the duck-billed platypus was published by an international team of scientists, revealing clues about how genomes were organized during the early evolution of mammals. The research was supported in part by the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH).

Decoded Platypus Genome Spells Out 'Hybrid'

The duck-billed platypus looks and acts like an animal with an identity crisis. It swims a bit like a duck and walks like one, too (on those webbed little feet), but it's certainly no bird. It lays eggs, as if a bird or reptile, yet it nurses its young like the mammal that it is. Now, it turns out the animal looks like a hybrid even at the most minute level, its DNA. Along with today's announcement that the platypus's genome has been sequenced comes the revelation that its genes reflect its odd ancestry.

Platypus Genome Sequenced, Unlocking Secrets Of Evolution

By any account, the platypus is an odd creature. It's got a broad, rubbery bill that brings to mind a duck....but it swims more like a beaver....yet it lays eggs and can inject poisonous venom, like a reptile. No wonder it was considered an elaborate hoax by scientists who examined the first specimen pelt shipped to England from the colony of New South Wales in 1799.

The model fungus Podospora anserina (P. anserina) has undergone substantial evolution since its separation from Neurospora crassa, as revealed from the Podospora draft genome sequence published in Genome Biology. The study also shows that the Podospora genome contains a large, highly specialised set of genes potentially involved in the breakdown of complex carbon sources, which may have potential use in biotechnology applications.
