Mitogen‐activated protein kinase (MAPK) cascades are important signaling modules
regulating diverse biological processes. During the past 20 years, much progress has been …

Anionic phospholipids, which include phosphatidic acid, phosphatidylserine, and
phosphoinositides, represent a small percentage of membrane lipids. They are able to …

Vesicle exocytosis and endocytosis control the activities and turnover of plasma membrane
proteins required for signaling triggering or attenuating at the cell surface. In recent years …

Plants as non-mobile organisms constantly integrate varying environmental signals to
flexibly adapt their growth and development. Local fluctuations in water and nutrient …

Pollen tube growth requires coordination of cytoskeletal dynamics and apical secretion. The
regulatory phospholipid phosphatidylinositol 4, 5-bisphosphate (PtdIns (4, 5) P2) is enriched …

Different phosphoinositides enriched at the membranes of specific subcellular
compartments within plant cells contribute to organelle identity, ensuring appropriate cellular …

Pollen tubes rapidly elongate, penetrate, and navigate through multiple female tissues to
reach ovules for sperm delivery by utilizing a specialized form of polar growth known as tip …

RabA4 subfamily proteins, the key regulators of intracellular transport, are vital for tip growth
of plant polar cells, but their unique distribution in the apical zone and role in vesicle …

Plant cytokinesis involves membrane trafficking and cytoskeletal rearrangements. Here, we
report that the phosphoinositide kinases PI4Kβ1 and PI4Kβ2 integrate these processes in …
