#Decoding the genetic history of the Texas longhornlonghorn cattle have a hybrid global ancestry according to a study by University of Texas at Austin researchers published this week in the Proceedings of the National Academy of Sciences.
and there's evidence that this genetic diversity is partially responsible for their greater resilience to harsh climatic conditions.
To reconstruct the genetic history of Texas longhorns Mctavish Hillis and colleagues from the University of Missouri-Columbia analyzed almost 50000 genetic markers from 58 cattle breeds.
The most comprehensive such analysis to date it was funded in part by the Cattlemen's Texas longhorn Conservancy
But their genetic signature is co mpletely consistent with being direct descendants of the cattle Columbus brought over.
Having that genetic reservoir from those wild ancestors made it possible for a lot of those traits to be selected for once again.

University of Arizona geneticists have discovered the oldest known genetic branch of the human Y chromosome--the hereditary factor determining male sex.
The results are published in the American Journal of Human genetics. Our analysis indicates this lineage diverged from previously known Y chromosomes about 338000 ago a time
Unlike the other human chromosomes the majority of the Y chromosome does not exchange genetic material with other chromosomes
When none of the genetic markers used to assign lineages to known Y chromosome groupings were found the DNA sample was sent to Family tree DNA for sequencing.
Hammer said the most striking feature of this research is that a consumer genetic testing company identified a lineage that didn't fit anywhere on the existing Y chromosome tree
It is a misconception that the genealogy of a single genetic region reflects population divergence.
Finding that particular species or that individual tree that has the genetic markers for the optimal biofuel candidate has heretofore been laborious and painstaking.
Combining the HTAP chemical phenotypes with information such as genetic markers can signal there is a gene nearby that controls those chemical phenotypes--for better or worse.
which looked at their genetic transformations and the associated cell-wall chemistry changes Davis said. They discerned dozens of changes in transgenic biomass samples each slight genetic tweak corresponding with a slight difference in the amount of lignin in the sample.
NREL was able to tell Arborgen that one sample had say half the lignin of another sample.
and the University of California Davis to demonstrate that the HTAP method could combine with genetic information to identify genetic markers associated with cell wall chemistry traits.
Even with this approach the method that would soon evolve into HTAP identified numerous genetic markers associated with cell wall chemistry
HTAP provides the information that combined with other genetic information tells us there's a gene controlling the plant's cell wall chemistry located somewhere on this chromosome--at the same location every time Davis said.
Our partners have genetic markers for 1000 trees and can pinpoint the gene that has an effect on lignin content cellulose content
and find a tree in the natural population with similar genetic traits or use genetic transformation to introduce the desirable traits.
The data from the chemical makeup is averaged and generated in real time. If we know what each of these peaks are related to we can tell what has changed with each sample Davis said.

Between two leaves of the same tree there can be many genetic differences--this study found ten SNP including ones in genes that regulate terpene production
Organisms collect somatic genetic mutations throughout their lives. These mutations may have no effect or they may occur in genes important to how the cell behaves.
Cancer cells often have genetic mutations which permit the cell to divide more times than an unmutated cell
At a genetic level there were ten genes which contained differences between these leaves. Amanda Padovan who led this project explained The main defence against predation of Eucalyptus is a cocktail of terpene oils including monoterpenes sesquiterpenes and FPCS
