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.

New Biocontainment Strategy Controls Spread of Escaped GMOs

Hiroshima University (HU) researchers successfully developed a biocontainment strategy for genetically modified organisms, or GMOs. Their new method prevents genetically modified cyanobacteria from surviving outside of their test environment, enabling ways to more safely research the effects of GMOs. Their results were published in ACS Synthetic Biology.

Japan to Decide GE Labeling Requirements Soon

The Consumer Affairs Agency’s expert committee is expected to conclude its review of Japan’s
labeling requirements for genetically engineered foods at the end of March 2018. As a part of the
ongoing review, informal discussions have begun on a possible stricter threshold for the use of
voluntary “non-GE” labeling. However, some participating expert members have expressed concern
that foreign grain and oilseed supplies could be disrupted by a new, stricter standard. The concept of
tighter requirements for “non-GE” labeling is expected to be the focus of the next (and likely final)
expert committee meeting. Read more
