This makes a big vacuole more effective at volume expansion. Gilroy, S. & Trewavas, A. Signal processing and transduction in plant cells: the end of the beginning? Nature Reviews Molecular Cell ...

Damage to the cell wall can lead to vacuole rupture and cell death. A conserved mechanism involving ATG8ylation, where ATG8 is relocated to the vacuole membrane, helps protect against this.

The team aims to further study how the plant cell senses the damage to the cell wall, as well as how exactly ATG8 conjugation protects vacuolar integrity. "Unraveling this process will be ...

Water-filled vacuoles provide the inner pressure plant cells need for structural support. However, damage to the plant’s cell wall risks vacuole rupture and cell death. The Dagdas group at the ...
