Manipulating how plants express their genes holds the promise of higher crop yields and better performance under drought or other environmental stress.
Over the last decade or so, biologists have mustered an ever-growing appreciation for the essential role of microbial communities in a diversity of environments.
University of Montreal researchers have discovered how telomerase, a molecule essential for cancer development, is directed to structures on our genome called telomeres in order to maintain its integrity and in turn, the integrity of the genome.
Chromatin states can influence transcription directly by altering the packaging of DNA to allow or prevent access to DNA-binding proteins, or they can modify the nucleosome surface to enhance or impede recruitment of effector protein complexes.
