How do plants breathe through stomata? Key regulators of stomata are plant vacuoles, fluid-filled organelles bound by a single membrane called the tonoplast. Plant vacuoles are fluid-filled organelles ...

A research team has revealed the molecular steps that led to the emergence of this plant-specific vacuolar transport system. Their work shows that the acquisition of this pathway was driven by the ...

Journal of Experimental Botany, Vol. 66, No. 5 (2015), pp. 1191-1203 (13 pages) Tonoplast intrinsic proteins (TIPs) are integral membrane proteins that are known to function in plants as aquaporins.

Disease-causing microorganisms hide in protective bubbles on the cell surface called vacuoles, making it difficult for the immune system to recognize and destroy them without causing harm to the rest ...

Being a segregase, it’s the job of valosin-containing protein (VCP) to straighten out a myriad of poorly folded proteins. We can now add tau to that list. In a paper published in Science on October 1, ...

New research, published today in the journal Science, shows how lysosomes — organelles that act like cells’ waste disposal system — respond to stress by becoming abnormally bloated, a process called ...

The inside of a cell is like a house that has a lot of rooms. Little compartments called organelles are the intracellular versions of organs like the liver or the pancreas in the body. Each organelle ...

This illustration shows how the membrane trafficking protein VAMP72 gradually changed during plant evolution to give rise to VAMP727, which functions in transporting storage proteins to vacuoles. The ...
