Ouch! Plant perception of wounding

Sözen et al. describe two independent MAPK signaling cascades that are each activated with different kinetics, providing an immediate and delayed response to herbivore feeding. The Plant Cell (2020) https://doi.org/10.1105/tpc.19.00917 By Cécile Sözen, Marie Boudsocq and Jean Colcombet, Université…

Insect-damaged Arabidopsis moves like wounded Mimosa pudica (PNAS)

Stroking leaves of the sensitive plant Mimosa pudica causes them to fold inwards, but when touched more aggressively the leaf petioles and petioles of distal untouched leaves collapse dramatically downwards (as seen in this video); the propagating electrical signal is called the slow wave potential.…

A jasmonate signaling network activates root stem cells and promotes regeneration ($) (Cell)

Plants possess plasticity for regeneration of organs after damage by physical, biotic or abiotic stress. The mitotically less-active organizer cells, quiescent center (QC) and surrounding initials form the stem cell niche, which is known to play a very important role in activation of the regeneration…
