Calcium (Ca2+) is a unique mineral that serves as both a nutrient and a signal in all
eukaryotes. To maintain Ca2+ homeostasis for both nutrition and signaling purposes, the …

Root hair cells and pollen tubes, like fungal hyphae, possess a typical tip or polar cell
expansion with growth limited to the apical dome. Cell expansion needs to be carefully …

In flowering plants, pollen germinates on the stigma and pollen tubes grow through the style
to fertilize the ovules. Enzymatic production of reactive oxygen species (ROS) has been …

Drought is a major abiotic stress that threatens maize production globally. A previous
genome‐wide association study identified a significant association between the natural …

Signaling with Ions: The Keystone for Apical Cell Growth and Morphogenesis in Pollen Tubes |
Plant Physiology | Oxford Academic Skip to Main Content Advertisement Oxford Academic …

Reactive oxygen species (ROS), a type of oxygen monoelectronic reduction product, have a
higher chemical activity than O2. Although ROS pose potential risks to all organisms via …

During pollen tube growth, the walls of the tube provide the mechanical strength resisting
turgor pressure to protect two sperm cells. Cell wall proteins may play an important role in …

Pollen tube integrity is required for achieving double fertilization in angiosperms. The rapid
alkalinization factor4/19-ANXUR1/2-Buddha's paper seal 1/2 (RALF4/19-ANX1/2-BUPS1/2) …

The pollen tube is fundamental for the reproduction of seed plants. Characteristically, it
grows relatively quickly and uni‐directionally (“polarized growth”) to extend the male …

Tip growth is an extreme form of polarized cell expansion that occurs in all eukaryotic
kingdoms to generate highly elongated tubular cells with specialized functions, including …
