Our current manuscript is how Bradyrhizobium elkanii synthesis exopolysaccharide (EPS). No one knows it.

It’s a great feeling when your boss presents your data on a big stage! 🔬✨ I am proud to see our work on phosphate signaling and nodulation featured at #2025MPMI. 📄 Read our paper: doi.org/10.1093/pcp/pc… Phosphate is key for efficient root nodule symbiosis. @OswaldoValdesl
Special moment at #ISMPMI2025 🌱 With my former postdoc mentor, Prof. @OswaldoValdesl, and his PhD. mentor, Prof. Georgina Hernández—three academic generations in one frame! I am grateful for the mentorship, support, and science that connects us across time and continents. 🙏
This is v interesting! Not only nitrogen status but also phosphate status impacts nitrogen fixing symbiosis. New paper by @IamJawaharSingh from his time @OswaldoValdesl lab.👇
Happy to share the latest manuscript from our lab in collaboration with @IamJawaharSingh, @MCaro_IArellano, and @JeanMichelAne Phosphate deficiency reduces nodule formation through a Phosphate Starvation Response -Like protein in Phaseolus vulgaris academic.oup.com/pcp/article/do…
It was a great experience working with Prof. @OswaldoValdesl on this nice project for my 1st postdoctoral research funded by @UNAM_MX.

Congratulations, @dromius Sebastian Schornack, on your well-earned title of Research Professor 2025! Your passion for discovery inspires us all. Here’s to celebrating with some Prosecco! 🎉🍾 #ResearchProf
This made me very happy.
I'll be at #IPGSA2025 in 10 days time - come find me at poster 102 to discuss what we've learned in rice about the role of KL & its negative regulator SMAX1 in root development, mycorrhizal symbiosis and germination, as well as our efforts to take chemical control of this pathway
🌱 Excited to host Dr. Oswaldo Valdés López from UNAM 🇲🇽 at the Sainsbury Lab, Cambridge! Join us on Monday 21 July, 14:00 as he unravels how phosphate availability shapes legume–rhizobia symbiosis. 📍 Auditorium + Zoom #PlantScience #Symbiosis #Legumes #SainsburyLab
🌍 Excited to announce our 1st Mentor Panel for the IS-MPMI 2025 Satellite Meeting! 🌱Building Careers in MPMI through Effective Mentoring 🗓️13th July 2025 Cologne, Germany 🌟Join global leaders in plant-microbe interactions as they share career insights and mentoring wisdom.
