Abstract Phospholipases D (PLD) and C (PLC) hydrolyze the phosphodiesteric linkages of
the head group of membrane phospholipids. PLDs and PLCs in plants occur in different …

Pollen tubes extend rapidly via tip growth. This process depends on a dynamic actin
cytoskeleton, which has been implicated in controlling organelle movements, cytoplasmic …

Roots hairs are cylindrical extensions of root epidermal cells that are important for
acquisition of nutrients, microbe interactions, and plant anchorage. The molecular …

Trichomes and root hairs differentiate from epidermal cells in the aerial tissues and roots,
respectively. Because trichomes and root hairs are easily accessible, particularly in the …

Mechanical stimulation of plants triggers a cytoplasmic Ca2+ increase that is thought to link
the touch stimulus to appropriate growth responses. We found that in roots of Arabidopsis …

Plant cells grow through increases in volume and cell wall surface area. The mature
morphology of a plant cell is a product of the differential rates of expansion between …

Pollen tube growth attracts our attention as a model system for studying cell elongation in
plants. The process is fast, it is confined to the tip of the tube, and it is crucial for sexual …

The actin cytoskeleton is one of the major structural components of the cell. It often
undergoes rapid reorganization and plays crucial roles in a number of dynamic cellular …

Here we report on a lipid‐signalling pathway in plants that is downstream of phosphatidic
acid and involves the Arabidopsis protein kinase, AGC2‐1, regulated by the 3 …

Key message Overview of pollen development. Abstract Male gametophyte development of
angiosperms is a complex process that requires coordinated activity of different cell types …
