US study uncovers 275 million entirely new genetic variants

Posted by in categories: biotech/medical, genetics, health

CHICAGO, Feb 19 (Reuters) — A study that analyzed the genetic code of a quarter of a million U.S. volunteers found more than 275 million entirely new variants that may help explain why some groups are more prone to disease than others, researchers reported on Monday.

The whole genome sequencing data from a wide range of Americans aims to address the historical lack of diversity in existing genomic datasets by focusing on previously under-represented groups. The U.S. National Institutes of Health-funded “All of Us” study turned up 1 billion genetic variants in total.

“Sequencing diverse populations can lead to new drug targets that are relevant to everyone,” said Dr. Josh Denny, a study author and its chief executive. “It can also help uncover disparities that lead to specific treatments for people that are experiencing higher burdens of disease or different disease.”

Startup Clones Three Piglets Gene-Hacked to Have Organs Transplanted Into Humans

Posted by in categories: biotech/medical, genetics

Japanese startup PorMedTec says it’s have cloned three piglets with the express purpose of having their organs be viable for transplantation to humans, without being rejected by the immune system.

The company imported gene-edited cells from a US biotech startup called eGenesis and used them to create genetically modified embryos, the Japan Times reports, which were then implanted into the uterus of a pig.

“The realization of xenotransplantation has been long awaited in Japan for several years, but it remained in the basic research stage because pigs that could withstand clinical application were still under development,” the company said in a statement.

Scientists identify genetic mechanism responsible for plant leaf diversity

Posted by in categories: biological, genetics

Plant leaves come in many different shapes, sizes and complexities. Some leaves are large and smooth, while others are smaller and serrated. Some leaves grow in single pieces while others form multiple leaflets. These variations in leaf structure play a crucial role in how plants adapt—and survive—in different environments.

“Plant morphology is diverse in nature,” said Zhongchi Liu, a professor emerita in the University of Maryland’s Department of Cell Biology and Molecular Genetics. “Morphological differences contribute to plant survival, including how well plants can regulate their temperatures and how efficiently they can transport water from their roots to the rest of their bodies.

Understanding the mechanisms responsible for diverse leaf forms will lead to a better understanding of how plants can survive challenging conditions.

Near-gapless and haplotype-resolved apple genomes provide insights into the genetic basis of rootstock-induced dwarfing

Posted by in categories: biotech/medical, genetics

Near-gapless and haplotype-resolved genome assemblies of the dwarfing ‘M9’ and semi-vigorous ‘MM106’ rootstocks and a major apple cultivar ‘Fuji’ provide insights into the genetic basis of rootstock-induced dwarfing traits.
