Extended Data Fig 6: Leaf movement in response to dehydration in Polytrichum.
From: Advanced vascular function discovered in a widespread moss
As shoots of Polytrichum commune desiccate, leaves move from a position that is perpendicular to the stem (image top right) to being arranged parallel to the stem (image lower right). The relationship between leaf angle and ψshoot for five individuals subjected to slow desiccation (each color represents a different replicate plant) shows a rapid decline in leaf angle as ψshoot fell from 0 to −1.5 MPa. This pattern of decline matched closely the pattern of declining diffusive conductance seen in Fig. 3.
