Blazes of light reveal how plants signal danger long distances

By long distances they mean within the plant, from leaf to stem to leaf. Does anyone know Gilroy, he looks like a wild man.

What doesn't kill them makes them stronger.

My observation, lots of botanists are a bit rrrright or lefffft of center. We've had a few here at K-State. Wisconsin has had more than their share through the years. For instance Hugh Iltis (evolution of maize) and Folke Skoog (M.S. medium).I see that Gilroy was educated at Edinburgh.

How plants adapt: Calcium waves help the roots tell the shoots
https://phys.org/news/2014-04-calcium-roots.html#nRlv

This linked article is at least as interesting, because it seems to connect with calcium tolerance. This relates to "a protein channel called two pore channel 1 (TPC1)."

"Plants with more channels also grew larger and contained more chlorophyll than plants with normal or mutated TPC1 when grown in salt water."

Considering that they were tracing a calcium wave traveling through these channels, I would guess that availability of calcium might be relevant, though I can't guess just how.

This research also interests me because of Amzallag's research into the inheritance of acquired tolerance to salt spray.
