Extended Data Fig 4: Refilling kinetics in Polytrichum.
From: Advanced vascular function discovered in a widespread moss
Hydroids of the central strand of a single Polytrichum commune caulidium are shown to refill after a droughted plant that had fully cavitated was rehydrated after several hours ( > 12) after the last cavitation event was observed. Data from a single individual stem from an intact plant shows that 90 min after rewatering from both phyllidia and rhizome the hydroids begin to effectively refill with water, compressing the air into nanobubbles (which should dissolve over time) at around 125 min after rewatering of the plant. Average relative hydroid refilling state (proportion of water present in hydroids) over time is shown as black dots, while individual hydroid refilling states for each hydroid are shown as grey dots.
