植物的细胞质分裂依赖于微管的不对称行为：在膜质先导区进行整体聚合，在膜体滞后区进行整体解聚。最近的研究结果表明，磷脂酰肌醇4-激酶β(PI4Kβ)在这种不对称性中起着重要作用，它促进了膜质形成滞后区的建立。
Plant cytokinesis rely on asymmetric behavior of microtubules: bulk polymerization at the phragmoplast leading zone and bulk depolymerization at the phragmoplast lagging zone. Recent findings demonstrate that phosphatidylinositol 4-kinase beta (PI4Kβ) plays an essential role in this asymmetry by facilitating the establishment of the phragmoplast lagging zone.
