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 ...

In plant cells, the largest organelle by far is the so-called vacuole. Enveloped by a membrane, it stores substances vital for the plant cell -- for example, proteins essential for our nutrition found ...

Figure 2: A block in vacuole inheritance or deletion of the Vac17p PEST sequence results in elevated levels of Vac17p. Figure 4: Regulated degradation of Vac17p releases Myo2p and deposits the ...

Many plant processes are not different from humans: Cells and tissues in grain plants, including maize also communicate through electrical signals. The shape and frequency of these signals tell a ...

Plants droop and shed their leaves when parched, but with a splash of water, their stems regain strength and their leaves unfurl. This dramatic transformation is a clear signal for us to reach for the ...

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 ...

Researchers have shown for the first time that a specific protein plays an indispensable role in the formation of vacuoles, by far the largest organelles in plant cells. Enveloped by a membrane, ...
