Extreme salt stress triggers leaf movement

Plant leaves can cope with much higher salt concentrations than roots. The underlying mechanism may help to develop more salt-tolerant crops.

Modulating cells' chloride channels

Laboratory cell experiments and computer simulations have revealed molecular mechanisms regulating a protein channel responsible for transporting chloride and other charged molecules across cell membranes. The findings were ...

Scientists reveal the structure of viral rhodopsins

The structure of an Organic Lake Phycodnavirus rhodopsin II (OLPVRII), which is a unique protein found in the genome of giant viruses, has been determined thanks to the work of MIPT graduates and Ph.D. students. The paper ...

Gene for acid-sensitive ion channel identified

In the human body the salt content of cells and their surrounding is regulated by sophisticated transport systems. Special channels in the cell membrane selectively permit salt ions to flow in and out of cells. A research ...

Key acid-activated protein channel identified

Johns Hopkins researchers have discovered a long-sought protein, the proton-activated chloride channel (PAC), that is activated in acidic environments and could protect against the tissue-damaging effects of stroke, heart ...
