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 ...

Just like in yeast and animal cells, vacuoles in plants are responsible for breaking down unwanted cellular components. At ...

This process of lysosomal vacuolation is a natural, highly regulated response. LYVAC plays a central role in this process, helping cells adapt to stress and maintain lysosomal stability. Discover the ...

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 ...

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 ...
