▪ 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 …

Propagation of viral infection in host plants comprises two distinct and sequential stages:
viral transport from the initially infected cell into adjacent neighboring cells, a process termed …

The organization of microtubule arrays in the plant cell cortex involves interactions with the
plasma membrane, presumably through protein bridges. We have used immunochemistry …

Sexual reproduction of flowering plants depends on delivery of the sperm to the egg, which
occurs through a long, polarized projection of a pollen cell, called the pollen tube. The …

Main conclusion Heat stress changes isoform content and distribution of cytoskeletal
subunits in pollen tubes affecting accumulation of secretory vesicles and distribution of …

Plant viruses are obligate organisms that require host components for movement within and
between cells. A mechanistic understanding of virus movement will allow the identification of …

A variety of microtubule-associated proteins (MAPs) have been reported in higher plants.
Microtubule (MT) polymerization starts from the γ-tubulin complex (γTuC), a component of …

Microtubule organization is intimately associated with cellulose microfibril deposition, central
to plant secondary cell wall development. We have determined that a relatively large suite of …

The movement protein of tobacco mosaic virus, MP30, mediates viral cell-to-cell transport
via plasmodesmata. The complex MP30 intra-and intercellular distribution pattern includes …

Key message The pollen tube is being subjected to control by a complex network of
communication that regulates its shape and the misfunction of a single component causes …
