Scientists Crack the Code to Improve Stress Tolerance in Plants

In any eukaryotic organism, the DNA in a cell exists not as a loose strand, but as a highly condensed complex that consists of DNA and other proteins known as histones. Overall, this condensed structure is referred to as chromatin, and this packaging is important for maintaining the integrity of DNA structure and sequence. However, as chromatin restricts the topology of DNA, modification of chromatin (via modification of histones) is an important form of regulation of genes and is referred to as epigenetic regulation.

With its CRISPR Revolution, China Becomes a World Leader in Genome Editing

Editing of plant, animal, and human genomes has never been easier, as this country’s scientists are rapidly demonstrating.

For many people, CRISPR plus China equals the biophysicist He Jiankui, who infamously used the genome editor last year to alter the DNA of two human embryos that would become twin girls. Before his announcement, He was little-known within the country’s CRISPR community, which has grown rapidly and is now challenging—and by some measures surpassing—the United States in its use of the powerful tool.

We Dislike GM Foods Because We’re Ignorant About Them

Protesters of the recent application of a confined  genetically modified (GM)  rice field trial at the Malaysian Agricultural Research and Development Institute (Mardi) Arau station in Tambun Tulang, Perlis, claimed that GM rice threatens Malaysia as a centre of genetic diversity for rice.

Making Biotechnology Acceptable to More Filipinos

To address the  problem of  providing food to a rapidly growing population,  the  scientific  communities  worldwide including the Philippines are  advocating a balanced, safe  and sustainable approach  using the best conventional  crop technology and the best of biotechnology to achieve sustainable food production.  Biotechnology is a modern technology that makes use of organisms (or parts thereof) to make or modify products; improve and develop microorganisms, plants or animals; or develop organisms for specific purposes in a more precise manner.

New technology for protein complex discovery holds promise for biotechnology and crop improvement

Living cells survive and adapt by forming stable protein complexes that allow them to modulate protein activity, do mechanical work and convert signals into predictable responses, but identifying the proteins in those complexes is technically challenging. Purdue University researchers have developed a method to predict the composition of thousands of proteins complexes at one time, a discovery that will speed discoveries about cell functions. Read more
