Yellow coloured banners border the top and bottom of the page and in the centre the image depicts a whiteboard illustration of the original concept behind the workshop ‘Plant Energy Management: Molecular Mechanisms and Signalling,’ held at UPSC, Sweden, in August 2024. The aim was to expand upon the original TOR meeting by focusing on the inputs and outputs of the core energy management machinery in a species-agnostic manner.

This paper is the result of the fantastic work of Justine Broutin who successfully defended her PhD on the 19th of February! Congrats Dr Justine!😄👍

Oui les sources pour ce genre d’affirmations ne sont jamais citées car effectivement elles n’existent pas…on vise surtout et encore à faire peur!

🚜What are the underlying processes behind the positive effect of protein hydrolysates on growth/yield?
🌱Its clear and robust effect on Arabidopsis growth goes with changes at transcriptome & metabolite levels.

Waou… Il y a des jours où je n’ai plus les mots.
À 17h, déjà 149 records de chaleur ont été battus en France, y compris dans des stations installées au XIXᵉ siècle. En FEVRIER, s'il vous plait (quel délire !), on approche les 30°C au pied des Pyrénées, plus de 25°C sur la moitié nord.

Bravo et merci pour ce superbe parcours !👍

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 🌽

- 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!

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.

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!

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!
