Abstract

In his Perspective, Grebe discusses how a plant proton pump residing in intracellular compartments, rather than in the plasma membrane of the cell surface, regulates growth and development. The pump modulates the expression at the plasma membrane of both a transporter for the hormone auxin and another proton pump. These findings open new views on how plants regulate cell wall acidity and hormone transport during development.

摘要

在他的《视角》一文中，格雷贝探讨了一种存在于细胞内区室而非细胞表面质膜中的植物质子泵如何调节生长和发育。该泵调节质膜上激素生长素转运蛋白和另一种质子泵的表达。这些发现为植物在发育过程中如何调节细胞壁酸度和激素运输开辟了新的视角。
