▪ Abstract Many aspects of Angiosperm pollen germination and tube growth are discussed
including mechanisms of dehydration and rehydration, in vitro germination, pollen coat …

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 …

Advances in plant cell molecular biology have considerably increased our understanding of
pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the …

All living cells use a network of signal transduction pathways to conduct developmental
programs, obtain nutrients, control their metabolism, and cope with their environment. A …

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 …

Tip-growing pollen tubes provide a useful model system to study polar growth. Although
roles for tip-focused calcium gradient and tip-localized Rho-family GTPase in pollen tube …

Ca2+ signals are thought to play important roles in plant growth and development, including
key aspects of pollen tube growth and fertilization. The dynamics of a Ca2+ signal are …

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 …

Pollination in flowering plants begins when pollen lands on a stigma. The process continues
as the pollen germinates and grows through intercellular spaces in the pistil, and it …

Ratio images of cytosolic Ca2+ (Ca2+ i) in growing, fura-2-dextran-loaded Lilium longiflorum
pollen tubes taken at 3-to 5-sec intervals showed that the tip-focused [Ca2+] i gradient …
