Abstract

To introduce pits into a cell wall, plants depolymerize cortical microtubules, which prevents subsequent secondary cell wall thickening. A newly identified protein tethers microtubules to the plasma membrane and contains this breakdown to defined regions, thereby shaping these holes.

摘要

为了在细胞壁上引入凹陷，植物会解聚皮质微管，从而阻止随后的次生细胞壁加厚。一种新鉴定的蛋白质将微管固定在质膜上，并使微管在特定区域发生断裂，从而塑造这些凹陷。
