Thermal response in plants: leaf hyponasty (Plant Phys)

Non-directional stimuli can trigger directional movements in plant organs. For instance, high temperature causes the upward bending of leaf petioles, a process known as leaf hyponasty, which helps to cool the leaves. In this study Park et al. explored the link between leaf thermonasty and auxins. Gene…

A mobile auxin signal connects temperature sensing in cotyledons with growth responses in hypocotyls (Plant Phys)

An increase in ambient temperature affects plant growth and development; for instance, high temperatures trigger elongation in petioles, hypocotyls, and roots in Arabidopsis seedlings. Bellstaedt et al. studied the spatial relationships in sensing, signaling and growth responses to high temperature in…
