Microsporogenesis in vivo and in vitro. Autofluorescence of pollen wall of Lilium and changes in pollen wall of Gasteria in Lilium anther [PDF]
Acta Societatis Botanicorum Poloniae, 2014 Autafluarescence of the pollen wall of Lilium shows a correlative change with its development. When the pollen of Gasteria is injected into the anther of Lilium, it exhibits almost the same characteristics of wall autofluorescence as those of Lilium ...

Persistent symmetry frustration in pollen tubes. [PDF]
PLoS ONE, 2012 Pollen tubes are extremely rapidly growing plant cells whose morphogenesis is determined by spatial gradients in the biochemical composition of the cell wall.

A peptide-mediated, multilateral molecular dialogue for the coordination of pollen wall formation. [PDF]
Proc Natl Acad Sci U S A, 2022 International audienceSignificance Pollen viability depends on a tough external barrier called the pollen wall. Pollen wall components are produced by tapetum cells, which surround developing pollen grains within the anther.

Pollen wall patterns as a model for biological self-assembly. [PDF]
J Exp Zool B Mol Dev Evol, 2021 We are still far from being able to predict organisms' shapes purely from their genetic codes. While it is imperative to identify which encoded macromolecules contribute to a phenotype, determining how macromolecules self‐assemble independently of the ...

Massively Parallelized Pollen Tube Guidance and Mechanical Measurements on a Lab-on-a-Chip Platform. [PDF]
PLoS ONE, 2016 Pollen tubes are used as a model in the study of plant morphogenesis, cellular differentiation, cell wall biochemistry, biomechanics, and intra- and intercellular signaling. For a "systems-understanding" of the bio-chemo-mechanics of tip-polarized growth

In vitro grown pollen tubes of Nicotiana alata actively synthesise a fucosylated xyloglucan. [PDF]
PLoS ONE, 2013 Nicotiana alata pollen tubes are a widely used model for studies of polarized tip growth and cell wall synthesis in plants. To better understand these processes, RNA-Seq and de novo assembly methods were used to produce a transcriptome of N. alata pollen
