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 these tissues. The first clue about organ-specific processes came from the transcriptomic analysis when […]
