气孔关闭相关肌动蛋白结合蛋白1(SCAB 1)通过介导肌动蛋白丝重组调控拟南芥气孔关闭。我们以前的研究表明,磷脂酰肌醇3-磷酸(PI 3 P)结合SCAB 1,并抑制其寡聚化,从而抑制其对气孔关闭期间保卫细胞中的F-actin的活性。在这项研究中,我们发现,另一种磷脂,磷脂酸(PA),也结合到SCAB 1,并抑制其肌动蛋白捆绑活动,但不是它的肌动蛋白结合活性。F-肌动蛋白捆绑促进在体内处理Col-0幼苗与正丁醇,PA生产的抑制剂,但这种效果是不存在的scab 1突变体。这些结果表明,信号分子PA参与调节F-肌动蛋白重组中的SCAB 1活性。
Stomatal closure-associated actin-binding protein 1 (SCAB1) regulates stomatal closure by mediating actin filament reorganization in Arabidopsis thaliana. Our previous study showed that phosphatidylinositol 3-phosphate (PI3P) binds to SCAB1 and inhibits its oligomerization, thereby inhibiting its activity on F-actin in guard cells during stomatal closure. In this study, we show that another phospholipid, phosphatidic acid (PA), also binds to SCAB1 and inhibits its actin-bundling activity but not its actin-binding activity. F-actin bundling was promoted in vivo by treating Col-0 seedlings with n-butanol, a suppressor of PA production, but this effect was absent in the scab1 mutant. These results indicate that the signaling molecule PA is involved in the modulation of SCAB1 activity in F-actin reorganization.
