Plant Science Research Weekly --  Macro Plant Projection Imaging (MAPPI): An open, scalable platform for whole-plant fluorescence real-time imaging (Science Advances) @labcosta.bsky.social (Summary by Indrani Kakati @indranik18.bsky.social) buff.ly/LxaRjzT #PlantaePSRW

With MAPPI, we can design simple fluorescent experiments for long-term Ca²⁺ imaging — 16 hours in this video — tracking signals (if any) during growth or dynamic movements 📷 @ScienceAdvances @science.org science.org/doi/10.1126/...

Plants "talk" internally — and now we can watch it happen. MAPPI lets us track shoot-to-root Ca²⁺ signals in real time 🌱⚡ @ScienceAdvance! @science.org science.org/doi/10.1126/...

Investigating the origin of spontaneous cytosolic calcium oscillations in stomatal guard cells: a dialogue between apoplastic and endoplasmic reticulum stores Grenzi et al. @labcosta.bsky.social nph.onlinelibrary.wiley.com/share/KRMCPP...

...we can infer that, in the presence of CPA, the ER behaves like anengine without fuel, incapable of sustaining the mechanism required to maintain the [Ca²⁺]cyt oscillations... doi.org/10.1111/nph....

Thrilled to share that Stefano Buratti has been awarded the Fratelli Confalonieri Postdoctoral Fellowship! He'll be joining my lab @LaStatale to develop innovative tools for exploring plant–environment interactions. Congratulations, Stefano!

What started as a 'funky' observation back in 2017 while visiting the lab of @labcosta.bsky.social, and after skilfull execution of Dominic Kuang, Shanna Romand, and many more, now found a home in Current Biology. www.sciencedirect.com/science/arti...

Interested in plant Ca2+ imaging? If you have (or are about to earn) a PhD, consider joining our team at La Statale (UNIMI) as a Postdoc. A great opportunity to grow your expertise in a vibrant research environment! Feel free to contact me to discuss applications to the MSCA
