Target of rapamycin kinase is involved in regulating maize radicle development through starch metabolism Abstract. Target of rapamycin (TOR) signaling plays a pivotal role in regulating various cellular processes, including energy metabolism and growth. In thi

Radicle, dude! 🏄

Liu et al show that 'target of rapamycin' or TOR signaling regulates #maize radicle development by modulating starch metabolism and energy homeostasis 🌽

Exactement ! Toujours le même problème depuis 30 ans…

Houlalala le suspens est insoutenable : ce reportage va t il être anti OGM ? quand on itw
- Une chercheuse qui a témoigné au procès des faucheurs volontaires en leur faveur
- une ancienne ministre farouchement antiOGM
- une ONG anti ogm
- le Criigen (au secours)
- un député PS anti ogm

Suspens

Que les plantes issues de NGT représentent une catégorie dOGMs ne veut pas dire qu’ils posent de fait une quelconque dangerosité ? En quoi devraient-ils représenter un risque systémique pour la
biodiversité ou la santé publique??

Indeed a great story illustrating how the plant TOR kinase can control the balance between growth and defense against pathogens !

Thank you to @ronaldpierik.bsky.social, Liên Bach, Christian Meyer, @fabien-senechal.bsky.social and Jean Colcombet for evaluating his work!

🍄 🛠️ TECHNICAL INNOVATION 🛠️ 🍄

In this technical advance, Decouard et al. show how to identify plant metabolites in root exudates specifically produced in the presence of arbuscular mycorrhizal fungi in an aeroponic-based system.

Guanosine tetraphosphate (ppGpp) signalling promotes high-light tolerance in Arabidopsis thaliana. Guanosine tetraphosphate (ppGpp) is a hyperphosphorylated nucleotide originally discovered in prokaryotes and found in the chloroplasts of plants and algae. In plants, ppGpp signalling plays a role as...

So glad to share a part of the PhD work of our student Justine Broutin that is now published in Physiologia plantarum! We explored the mechanisms of biostimulation by protein hydrolysates in plants using Arabidopsis and multi level phenotyping.

Ben oui elles été améliorées par la sélection:) ça m’a toujours paru bizarre de prétendre que les variétés anciennes sont plus résiliantes. Elles sont juste moins bonnes.

An important connection with the plant TOR signalling pathway!

Congratulations for this well deserved flower!

Merci Yann pour ces données ! On pourrait rajouter que l’utilisation du coton Bt en Australie a permis de réduire de moitié l’utilisation des insecticides.

An important paper illustrating the control of growth vs defense against pathogens by the antagonistic and connected SnRK1 / TOR kinases. One regulatory ring to rule them all:)

Congratulations for this important paper unveiling a mechanism for TOR activation by C metabolites in green organisms!
