Just as the platypus genome yielded insights into the emergence of mammals, Amborella s gives a glimpse at changes that helped flowering plants,
Comparisons of the genomes of Amborella and those of other plants suggest that an early ancestor of flowering plants gained a duplicate copy of its genome
analysis of the Amborella genome reveals. About one-quarter of the genes involved in flowering lack obvious counterparts in the genomes of gymnosperms,
whereas the other three-quarters existed in the common ancestor of both plant lineages. His team s analysis also provides insight into the evolution of complex seeds, floral scents and other features of flowering plants.

DNA of storied plant provides insight into the evolution of flowering plantsthe newly sequenced genome of the Amborella plant addresses Darwin's abominable mystery--the question of why flowers suddenly proliferated On earth millions of years ago.
The genome sequence sheds new light on a major event in the history of life On earth: the origin of flowering plants including all major food crop species. On 20 december 2013 a paper by the Amborella Genome Sequencing Project that includes a full description of the analyses performed by the project as well as implications for flowering plant research will be published in the journal Science.
The paper is among three on different research areas related to the Amborella genome that will be published in the same issue of the journal.
Amborella (Amborella trichopoda) is unique as the sole survivor of an ancient evolutionary lineage that traces back to the last common ancestor of all flowering plants.
An effort to decipher the Amborella genome--led by scientists at Penn State university the University at Buffalo the University of Florida the University of Georgia
In the same way that the genome sequence of the platypus--a survivor of an ancient lineage--can help us study the evolution of all mammals the genome sequence of Amborella can help us learn about the evolution of all flowers said Victor Albert of the University
Scientists who sequenced the Amborella genome say that it provides conclusive evidence that the ancestor of all flowering plants including Amborella evolved following a genome doubling event that occurred about 200 million years ago.
Genome doubling may therefore offer an explanation to Darwin's abominable mystery--the apparently abrupt proliferation of new species of flowering plants in fossil records dating to the Cretaceous period said Claude depamphilis of Penn State university.
Comparative analyses of the Amborella genome are already providing scientists with a new perspective on the genetic origins of important traits in all flowering plants--including all major food crop species. Because of Amborella's pivotal phylogenetic position
it is an evolutionary reference genome that allows us to better understand genome changes in those flowering plants that evolved later including genome evolution of our many crop plants--hence it will be essential for crop improvement stressed Doug Soltis of the University of Florida.
As another example of the value of the Amborella genome Joshua Der at Penn State noted We estimate that at least 14000 protein-coding genes existed in the last common ancestor of all flowering plants.
Jim Leebens-Mack from UGA noted that The Amborella genome sequence facilitated reconstruction of the ancestral gene order in the'core eudicots'a huge group that comprises about 75 percent of all angiosperms.
As an evolutionary outsider to this diverse group the Amborella genome allowed the researchers to estimate the linear order of genes in an ancestral eudicot genome
or multiply within the genome (transposable elements) seem to have stabilized in the Amborella genome. Most plants show evidence of recent bursts of this mobile DNA activity
and function of protein-coding genes so the cessation of mobile DNA activity may have slowed the rate of evolution of both genome structure and gene function.
In addition to its utility in retrospective studies of the evolution of flowering plants the Amborella genome sequence offers insights into the history and conservation of Amborella populations.

#Sugar beet genome sequenced and analyzeda new study published in Nature today describes the sugar beet reference genome sequence generated by researchers both from the Centre for Genomic Regulation (CRG) the Max Planck Institute for Molecular genetics and the University of Bielefeld in cooperation
with other centres and plant breeders. Sugar beet accounts for nearly 30%of the world's annual sugar production according to FAO and provides a source for bioethanol and animal feed.
The sugar beet genome sequence provides insights into how the genome has been shaped by artificial selection along time. What do foodstuff like muffins bread
Now a team of researchers from the Centre for Genomic Regulation (CRG) and the Max Planck Institute for Molecular genetics (Berlin Germany) lead by Heinz Himmelbauer head of the Genomics Unit at the CRG in Barcelona
The results of the study that will be published today in Nature shed also light on how the genome has been shaped by artificial selection.
Information held in the genome sequence will be useful for further characterization of genes involved in sugar production and identification of targets for breeding efforts.
which has sequenced its genome. This group encompasses other plants of economic importance like spinach or quinoa as well as plants with an interesting biology for instance carnivorous plants or desert plants. 27421 protein-coding genes were discovered within the genome of the beet more than are encoded within the human genome.
Sugar beet has a lower number of genes encoding transcription factors than any flowering plant with already known genome adds Bernd Weisshaar a principle investigator from Bielefeld University who was involved in the study.
The researchers speculate that beets may harbor so far unknown genes involved in transcriptional control
Many sequencing projects nowadays targeted at the analysis of novel genomes also address the description of genetic variation within the species of interest.
Commonly this is achieved by generating sequencing reads obtained from high-throughput sequencing technologies followed by alignment of these reads against the reference genome to identify differences explains Heinz Himmelbauer a principle investigator of this study.
and generated genome assemblies from four additional sugar beet lines. This allowed the researchers to obtain a much better picture of intraspecific variation in sugar beet than would have been possible otherwise.
In summary 7 million variants were discovered throughout the genome. However variation was distributed not uniformly: The authors found regions of high but also of very low variation reflecting both the small population size from
which has shaped the plants'genomes. Additionally gene numbers varied between different sugar beet cultivars which contained up to 271 genes not shared with any of the other lines as Juliane Dohm
or with disease resistance added Toni Gabaldon group leader in the CRG Bioinformatics and Genomics programme and ICREA research professor.
Finally the work also provides a first genome sequence of spinach which is a close relative of sugar beet.
Thanks to the sugar beet genome sequence made by the researchers and the associated resources generated future studies on the molecular dissection of natural

The analysis of the Rhizophagus irregularis genome has revealed that this asexual fungus doesn't shuffle its genes the way researchers expected.
and including researchers from the Department of energy Joint Genome Institute (DOE JGI) reported the complete genome of R. irregularis (formerly Glomus intraradices) in a paper published online November 25 in the journal Proceedings of the National
This is the first sequenced genome of arbuscular mycorrhizae the type that is dominant on the planet said Igor Grigoriev one of the senior authors on the paper and lead for the Fungal Genomics Program at the DOE JGI.
In 2006 shortly after the DOE JGI sequenced the first tree genome Populus trichocarpa it became apparent that it took a village (of other organisms) to raise a poplar tree.
Rhizophagus irregularis is the next in this linage to be released by the DOE JGI it follows the ectomycorrhizal fungal symbiont Laccaria the poplar rust pathogen Melampsora and dozens of bacterial genomes.
Analysis of the R. irregularis genome also revealed several surprising details. The research team found that the genome is among the largest fungal genomes sequenced weighing in at 153 million base pairs (Mb.
For comparison the button mushroom (Agaricus bisporus) also sequenced and published by the DOE JGI has a genome of about 30 Mb.
Through several generations portions of R. irregularis's genome were duplicated invaded by repeated transposable elements famously known as'jumping genes'.
'Unlike many other fungi R. irregularis seems to lack mechanisms that can keep these transposable elements from running amok.
Among the expanded portions of its genome R. irregularis had several genes for phosphorus metabolism
Through analysis of this and other mycorrhizal genomes we can help to better understand interactions

and other institutes have succeeded in unraveling the whole genome sequence of desert poplar Populus euphratica and the genetic bases underlying poplar to against salt stress.
Considering the limitation of next-generation sequencing for assembling complex genome and the high heterozygosity of desert poplar researchers used a newly developed fosmid-pooling strategy to sequence
and assemble the genome of this tree species. All the efforts yielded a high-quality genome sequence of desert poplar with high contiguity coverage
and accuracy further demonstrating the feasibility of this fosmid-pooling approach for de novo sequencing and assembly of a complex heterozygous genome.
The genome of desert poplar is very similar to that of the closely related mesophytic congener P. trichocarpa.
Researchers investigated the differences between the two genomes and suggested that P. euphratica diverged from P. trichocarpa within the last 8 to 14 million years.
Although both species shared at least two whole-genome duplication (WGDS) and exhibited extensive collinearity across the gene space species-specific genes involved in stress tolerance such as ion transport ATPASE activity transcript factor activity
and/or positively selected in the P. euphratica genome. When studying the adaptation mechanisms to against salt stress researchers found that several gene families likely to be involved in tolerance to salt stress contain significantly more gene copies in the P. euphratica lineage.
The complete genome sequencing of desert poplar revealed the underlying genetic mechanisms of poplar to against salt stress laying a solid foundation for accelerating the genetic breeding of cultivated poplars for saline and desert fields. said Junyi

In related research last May Wayne and his colleagues reported at the Biology of Genomes meeting in New york the results of their comparison of the complete nuclear genomes of three recent wolf breeds (from the Middle east East asia
We analyzed those six genomes with cutting-edge approaches and found that none of those wolf populations seemed to be closest to domestic dogs Wayne said.
Mitochondria are tiny sub-cellular structures with their own small genome. By comparing this ancient MITOCHONDRIAL DNA with the modern mitochondrial genomes of 77 domestic dogs 49 wolves
and four coyotes the researchers determined that the domestic dogs were grouped genetically with ancient wolves or dogs from Europe--not with wolves found anywhere else in the world or even with modern European wolves.
While Wayne plans to pursue this follow-up research he said he does not expect a nuclear genome analysis to change the central finding.
