Title: An amazing reaction happens when a plant gets hurt Written by: bio_man on Oct 1, 2018 (https://biology-forums.com/gallery/39/6_01_10_18_2_12_15.gif) (https://biology-forums.com/index.php?action=gallery;sa=view;id=39293) The short clip above shows what happens to an injured plant when a nibbling insect attacks the leaves of a plant: the entire plant is alerted to begin anticipatory defense responses. Working in the model plant Arabidopsis, researchers recently showed that a systemic signal begins with the release of glutamate, which is perceived by glutamate receptor–like ion channels upon injury to a leaf. The ion channels then set off a cascade of changes in calcium ion concentration that propagate through the phloem vasculature and through intercellular channels called plasmodesmata. This glutamate-based long-distance signaling is rapid; within minutes, an undamaged leaf can respond to the fate of a distant leaf. If plants react to injury more similarly to animals than we thought before, what will vegans eat now? Comments: Lol you're a drama queen ^^ Written by: 3sp on Oct 12, 2018 Plants have feelings too! Every day millions of inocent defencless plants are being killed. :( Written by: anuj on Oct 1, 2018 |
