How transcription factors explore the genome

Transcription factors (TFs) are proteins that regulate the transcription of genes, which is the first step in making a protein. The way TFs work is by searching the entire genome and binding to specific regions that regulate ...

Keeping chromosomes in check: A new role for heterochromatin

Although many people are aware that chromosomal damage and shortening contribute to the aging process, understanding how chromosomal defects occur is about more than just finding a way to turn back the clock. Large changes ...

How plants regulate sugar deposition in cell walls

Ultimately, researchers want to engineer bioenergy crops to accumulate large amounts of easy-to-use sugars. Researchers from the Great Lakes Bioenergy Research Center identified a major part of the sugar production process ...

Nuclear events make a flower bloom

Flowers are the reproductive organs of a plant. Their formation depends on strict nuclear events that, if compromised, can leave the plant sterile. A new study by researchers at the Nara Institute of Science and Technology ...

Mechanism for turning skin cells into blood stem cells uncovered

Researchers have succeeded in converting human skin cells into blood stem cells in an international collaboration project. "This is a first step on the way to generating fully functional blood stem cells in a petri dish which, ...

Activating a new understanding of gene regulation

Regulation of gene expression—turning genes on or off, increasing or decreasing their expression—is critical for defining cell identity during development and coordinating cellular activity throughout the cell's lifetime. ...

Gene network lets plant roots handle nitrogen

With robotics, computers and advanced genetics, researchers at the University of California, Davis and Cold Spring Harbor Laboratory are unraveling how plant roots take up and metabolize nitrogen, the key to plant growth ...

Regulating gene transcription using light

Researchers led by Mustafa Khammash have developed a new method that uses blue light to control the transcription of DNA into RNA in single cells. The technology could also be used in tissue engineering and stem cell research.
