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 📷

Plants "talk" internally — and now we can watch it happen.

MAPPI lets us track shoot-to-root Ca²⁺ signals in real time 🌱⚡

Using MAPPI for real-time whole-plant imaging, we reveal the earliest flooding response — a Ca²⁺ signal, expected, yet now directly visualised and strongest in young leaves...🔬📷

🔥 Spodoptera littoralis feeding doesn’t just spike cytosolic Ca²⁺ — it also unleashes a surge of apoplastic glutamate in Nicotiana benthamiana

The MAPPI setup we @AndreaBassi78 @labcosta.bsky.social
published in @ScienceAdvances shows its versatility, enabling us to design amazing experiments that we never thought could be possible...

So, now guess what this video is showing❔❔

...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....

Blue light decreases ER Ca²⁺ in stomatal guard cells, with refilling in the dark. Our new @newphyt.bsky.social study shows how ER Ca²⁺ shapes cytosolic Ca²⁺ dynamics
