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 ...

This protein storage function is unique to plant vacuoles and does not occur in other organisms. During evolution, plants developed a dedicated mechanism to transport large quantities of proteins into ...

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 ...

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 ...

Two well-known pathways for the degradation of chloroplast proteins are via autophagy and senescence-associated vacuoles. Here, we describe a third pathway that was activated by senescence-and abiotic ...

Researchers have filled two knowledge gaps: The vacuoles of plant cells can be excited and the TPC1 ion channel is involved in this process. The function of this channel, which is also found in humans ...

The delivery of proteins to the vacuole and its limiting membrane (the tonoplast) by the secretory system is thought to be a dissociative process in which vesicles bud from one compartment and fuse ...

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 ...

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 ...
