Excited to share our new work on pollen tube growth in Arabidopsis thaliana! 🌱 We show that vacuolar and ER Ca²⁺-ATPases are key regulators of calcium dynamics during pollen tube growth. A great collaboration with the Muschietti and Estevez labs 🤝 academic.oup.com/plphys/artic...

This was a wonderful defence of a very impressive thesis! Bianca, you did brilliantly, bravo! Thank you Alex for inviting me participate in this!

Many congratulations to Bianca on the successful defence of her PhD thesis! 🎉. And many thanks to @botanicaljim.bsky.social for being part of the committee and contributing to this important milestone.

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/...
