'Paternal' and 'maternal' DNA in fungi active at different times

Many types of mushroom have two different nuclei in their cells, one from the 'father' and another from the 'mother." Researchers at the universities of Delft, Utrecht and Wageningen have discovered that the genes from the ...

Cellular thermometer discovered

Scientists from Freie Universität Berlin have identified a mechanism that allows cells to adapt their gene expression program to very small changes in temperature. "Like a thermometer, these changes in gene expression follow ...

Outwitting climate change with a plant 'dimmer'?

Plants possess molecular mechanisms that prevent them from blooming in winter. Once the cold of win-ter has passed, they are deactivated. However, if it is still too cold in spring, plants adapt their blooming behavior accordingly. ...

What happens to gene transcription during DNA damage?

It's well known that when the DNA in a cell is damaged, the cell responds by activating specific genes that help defend the integrity of its genome. But less well studied is the fact that the cell actually shuts down the ...

Scientists deconstruct one of the myths of biological innovation

While the number of coding genes that produce proteins in humans has dwindled to 20,000 in recent years, scientists think that the dimensions of the proteome could be larger. This diversity of proteins has become one of the ...

Gene splicing in lice and the challenge of clothing

A terrific article recently published in Molecular Biology and Evolution, "Alternative Splice in Alternative Lice," provides a compelling example of maximizing genome information – adaptation of the louse Pediculus humanus ...
