The exception to the rule? TORC1 triggers growth under low nutrient environments

Trends Plant Sci. 2024 Jan;29(1):13-15. doi: 10.1016/j.tplants.2023.10.001. Epub 2023 Oct 16.

Abstract

Eukaryotic cells' proliferation and growth are controlled by the target of rapamycin kinase (TOR). TOR usually activates in favorable energy and nutritional circumstances. This is challenged by recent research, suggesting that plant cells optimized for nutrient absorption in low nutritional conditions may activate the TOR pathway in a polarized manner.
