Identification of regulatory promoter sequences directing MtCP6 transcription at the onset of nodule senescence in Medicago truncatula Abstract. The symbiotic association of legumes with rhizobia results in the formation of new root organs called nodules. However, the lifespan of nodules i

All good things (come to an end)...👋

Yang et al. have uncovered a new senescence-related nodule-specific regulatory region that (together with a stress-related ERF family member) regulates the onset of nodule senescence

Feeding symbiosis...

Singh @oswaldovaldesl.bsky.social et al show that the PHR-L7 transcription factor in common bean halts early nodulation under P-scarce conditions, linking nutrient availability with #nodulation

🍬 Sweet science in the RhizoLab!
Sugars do more than energize, they orchestrate nitrogen-fixing symbiosis in soybean nodules. Using single-cell & spatial omics, we’re uncovering how TOR, SnRK1 & HXK1 decode this sugary signal.

👀 A peek into the RhizoLab – Week 2!
We study the autoregulation of nodulation (AON) in soybeans—how plants control nodule numbers to balance nitrogen fixation and energy costs. We’re uncovering key proteins involved in this process using cutting-edge proteomics.
