작성자 sincere 작성시간17.08.28 Tension on the apoplastic water opens a mechanosensitive Ca2+ channel, a response that is augmented by apoplastic ABA. The resulting elevated cytoplasmic Ca2+ deactivates a plasmalemma H+/ATPase and also activates a K+‐H+ symport. The inflow of K+ and H+ depolarizes the membrane and renders the apoplast less acidic, the protons being removed to the vacuole and the K+ ions being re‐exported via the K+ outward rectifying channel.
굳이 말하자면 일단 칼슘이온이 증가할때 세포막의 k+/H+공동수송체가 작동해서 처음에는 약산성이 되지만 더 신속하게 액포 막에 있는 H+-ATPase가 작동한대요.
