➡️Plants don’t manage nutrients one at a time.
Sulfur metabolism is tightly wired to nitrogen, phosphorus, and iron networks. Our new review explores the regulatory hubs (SLIM1, PHR1, NLP7, FIT) shaping this nutrient cross-talk in Arabidopsis. academic.oup.com/jxb/article/...
Fig. 1 (shortened, full legend in paper): Regulation of TOR function by chloroplast-derived metabolites. (A) Photosynthetically derived sugars exported from the chloroplast activate TOR (via phosphorylation, P) in distal plant tissues. Sugar regulation of TOR can occur via SnRK1, or potentially via other routes (dashed arrow). Notably, TOR activation by sugar in roots requires mitochondrial function. (B) DHAP, a triose phosphate product of photosynthesis, positively regulates TOR in the green alga Chlamydomonas. (C) Active TOR directly phosphorylates the ABA receptor PYL, thereby inhibiting it. ABA, whose precursors are made in the chloroplast, binds PYL. ABA-bound PYL binds and inhibits the PP2C phosphatase, activating SNRK2. Active SNRK2 directly phosphorylates the RAPTOR subunit of TOR, inhibiting TOR activity.

Congrats @ottlab.bsky.social and @pengbo10.bsky.social for leading this work!
Our work on #hornwort #pyrenoids is finally out in @science.org! 🎉 We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...
Excited to share our latest preprint. Arabidopsis thaliana has been the leading model for plant genetics - but most of what we know comes from growth chambers.
Can this model also help us understand how climate shapes plants in the wild and reveal gene functions under real environmental variability?
Job opportunity!

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.

@Nature: an E3 ligase, acting via the jasmonate pathway, is a common regulator of both cold stress & phosphate uptake. Guided by AI, the authors use genome editing to show the relevance of this finding for improving maize yield in multi-site field trials.
