In Arabidopsis, ABA has been shown to activate the expression of ATGs and the formation of autophagosomes . ABA-activated SnRK2 can phosphorylate RAPTOR under osmotic stress, thereby inhibiting TOR signaling to induce autophagy . WebJun 17, 2024 · The plant glucose-TOR signaling network regulates not only universal metabolic processes in eukaryotes, including glycolysis, mitochondria functions, protein synthesis, and cell cycles, but also plant-specific processes, such as seed germination, cell wall synthesis, pigment production, and plant defense (Xiong and Sheen 2014).
WebHere, we show that the ancient eukaryotic TARGET OF RAPAMYCIN (TOR) metabolic signaling network controls PD transport in plants. TOR is a protein kinase that is activated by nutrients, including sugars, and then coordinates growth with nutrient availability. WebDec 7, 2015 · In plants, TOR signaling modifies growth and development in response to a plant’s energy status. An example of TOR action can be found in the root apices, which are active organs that explore the soil environment via vigorous growth and numerous tropisms.

WebABSTRACT. The TOR (Target of Rapamycin) signaling pathway, which takes TOR kinase as the core, regulates the absorption, distribution, and recycling of nutrients by integrating metabolic network and other signaling pathways, thus participating in the plant growth-defense trade-off.
