Bacteria belonging to the genera Rhizobium, Mesorhizobium, Sinorhizobium,
Bradyrhizobium, and Azorhizobium (collectively referred to as rhizobia) grow in the soil as …

Arabinogalactan proteins is an umbrella term applied to a highly diverse class of cell surface
glycoproteins, many of which contain glycosylphosphatidylinositol lipid anchors. The …

▪ Abstract Pollen tubes and root hairs are highly elongated, cylindrically shaped cells whose
polarized growth permits them to explore the environment for the benefit of the entire plant …

Pollen tubes grow rapidly by very fast rates and reach extended lengths to bring about
fertilization during plant reproduction. The pollen tube grows exclusively at its tip …

It has become increasingly apparent that the extracellular matrix (ECM), which in plants
corresponds to the cell wall, can influence intracellular activities in ways that go far beyond …

The apical wall of growing pollen tubes must be strong enough to withstand the internal
turgor pressure, but plastic enough to allow the incorporation of new membrane and cell …

We have shown that Rop1At, a pollen-specific Rop GTPase that is a member of the Rho
family of small GTP binding proteins, acts as a key molecular switch controlling tip growth in …

▪ Abstract Stomatal guard cells are unique as a plant cell model and, because of the depth of
present knowledge on ion transport and its regulation, offer a first look at signal integration in …

Arabinogalactan proteins (AGPs) are:(a) structurally complex macromolecules composed of
a polypeptide, large branched glycan chains, and lipid?;(b) markers of xylem development …

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 …
