+ Research Team Led by Prof. Zhang Mingfang Reveals Differential Homoeolog Gene Expression and Selection Behavior [09-18-2016] (Zhejiang University)

Edit Public Technologies 18 Sep 2016
Polyploidization is a prevalent phenomenon during the course of evolution in the plant kingdom ... These homoeolog expression dominance relationships among Brassicaceae genomes have contributed to selection response, predicting the directional effects of selection in a polyploid crop genome ... improvement that might be extendable to other polyploid crops....

Looking Different Than Your Parents Can Be an Evolutionary Advantage (University of California, Riverside)

Edit Public Technologies 08 Aug 2016
The work, which is outlined in a paper published today (August 8) in the journal Nature Plants, looked at polyploid hybrids in the genus Nicotiana, the group that includes tobacco. Unlike humans, which are diploids - with two copies of each of their 23 chromosomes (one from each parent) - polyploids can have three, four or more copies of each chromosome....

Low-level laser therapy may improve treatment of dangerous bleeding disorder (Massachusetts General Hospital)

Each of these giant, polyploid MKs generates many long, branched, small tubular structures called proplatelets that eventually fragment into thousands of platelets ... LLL treatment greatly increased mitochondrial generation in polyploid MKs, but the increase was only slight in less mature MKs with only two copies of each chromosome....

Bread wheat genome: a whole genome assembly available online on an INRA platform (INRA - Institut National de la Recherche Agronomique)

Edit Public Technologies 25 Jul 2016
(Source. INRA - Institut National de la Recherche Agronomique). Bread wheat (Triticum aestivum L.) is the most widely grown crop on earth and a staple food for one third of humans. Cultivated varieties have a complex genome comprised of 21 chromosomes, polyploid that is combining three subgenomes, the giant size of which represents five times that of the human genome ... https.//wheat-urgi.versailles.inra.fr/Seq-Repository/Assemblies....

Hybrid Species Are On The March – With The Help Of Humans

Edit IFL Science 09 Jun 2016
Those foreign plants were brought there, knowingly or unknowingly, by humans ... As polyploid plants carry twice as many chromosomes as their parents, they can no longer reproduce with either. The polyploid hybrid is thus its own biological species and unlike regular hybrids it cannot be easily “mated” into extinction. Many common crops such as strawberries or potatoes are polyploids, but the process occurs in nature too ... ....

New Mechanism for Wound Healing Identified by MDI Biological Laboratory Scientist (MDI Biological Laboratory)

Edit Public Technologies 17 May 2016
But what wasn't previously known is that these cells are a mechanism to respond to injury, and that their size is due to polyploidization, or an increase in the amount of DNA. instead of the usual two sets of chromosomes, polyploid cells have three or more....

Salamanders In All-Female Populations Regrow Their Tails Faster

Edit IFL Science 04 May 2016
Some Ambystoma salamander populations are all female, and they reproduce by cloning themselves, though they do mix it up by stealing sperm they find on leaves and twigs left behind by males of other species ... Lineages of unisexual salamanders have survived for millions of years ... Yet these salamanders thrive ... The higher tissue regeneration rates likely have something to do with the fact that these unisexual salamanders are polyploids ... ....

Allopolyploidization in goldfish x common carp [Genetics]>

Edit PNAS 03 Feb 2016
Polyploidy is much rarer in animals than in plants but it is not known why. The outcome of combining two genomes in vertebrates remains unpredictable, especially because polyploidization seldom shows positive effects and more often results in lethal consequences because viable gametes fail to form during meiosis. Fortunately, the goldfish... ....
