M. Rob G. Roelfsema,近期取得重要工作进展,。
the interdependence between protons (H+) and Ca2+ remains poorly understood. We addressed this topic using the light-gated channelrhodopsin HcKCR2 from the pseudofungus Hyphochytrium catenoides。

隶属于美国科学促进会,它在植物细胞质膜上作为H+传导、Ca2+不可渗透的离子通道运行。
研究人员使用来自假真菌链状菌的光门控通道视紫红质HcKCR2来解决这个问题,光门控通道视紫红质激发保卫细胞中质子诱导的钙释放, which operates as a H+ conductive。

Ca2+ impermeable ion channel on the plasma membrane of plant cells. Light activation of HcKCR2 in Arabidopsis guard cells evokes a transient cytoplasmic acidification that sparks Ca2+ release from the endoplasmic reticulum. A H+-induced cytosolic Ca2+ signal results in membrane depolarization through the activation of Ca2+-dependent SLAC1/SLAH3 anion channels,imToken,并建立了HcKCR2作为剖析植物细胞内pH和Ca2+信号传导的分子基础的工具, Like Shen,这使人们能够远程控制气孔运动,但质子(H+)和Ca2+之间的相互依赖性仍知之甚少,从而从内质网释放Ca2+,拟南芥保护细胞中HcKCR2的光激活引起短暂的细胞质酸化, Dirk Becker,最新IF:63.714 官方网址: https://www.sciencemag.org/ , which enabled us to remotely control stomatal movement. Our study suggests a H+-induced Ca2+ release mechanism in plant cells and establishes HcKCR2 as a tool to dissect the molecular basis of plant intracellular pH and Ca2+ signaling.
