Antisense oligodeoxynucleotide inhibition as an alternative and convenient method for gene function analysis in pollen tubes. [PDF]
PLoS ONE, 2013 Antisense oligodeoxynucleotide (A-ODN) inhibition works well in animal cells. However, there have been few successful examples to date of its application in plants, and more specifically whether the technique can be used in pollen tubes as a model of ...

2, 6-Dichlorobenzonitrile causes multiple effects on pollen tube growth beyond altering cellulose synthesis in Pinus bungeana Zucc. [PDF]
PLoS ONE, 2013 Cellulose is an important component of cell wall, yet its location and function in pollen tubes remain speculative. In this paper, we studied the role of cellulose synthesis in pollen tube elongation in Pinus bungeana Zucc.

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

Pollen Tube and Plant Reproduction [PDF]
International Journal of Molecular Sciences, 2019 The pollen tube was a fundamental step forward in the evolution of terrestrial plants; in fact, it allowed plants to liberate themselves from water demand during reproduction [...]

Pollen Germination and Pollen Tube Growth in Gymnosperms [PDF]
Plants, 2021 Pollen germination and pollen tube growth are common to all seed plants, but these processes first developed in gymnosperms and still serve for their successful sexual reproduction. The main body of data on the reproductive physiology, however, was obtained on flowering plants, and one should be careful to extrapolate the discovered patterns to ...

Collective excitations of germinating pollen grains at critical points
Scientific Reports, 2023 In plants, the germinating pollen grain (pollen tube) is a single, elongated cell that serves as a conduit through which gametes pass. Pollen tubes display a fast growth rate, which under certain conditions, changes periodically and is accompanied by ion

Durotropic Growth of Pollen Tubes [PDF]
Plant Physiology, 2020 To reach the female gametophyte, growing pollen tubes must penetrate different tissues within the pistil, the female reproductive organ of a flower. Past research has identified various chemotropic cues that guide pollen tubes through the transmitting tract of the pistil, which represents the longest segment of its growth path.

Pollen tube incompatibility reaction on the stigma in selfpollinated Sinapis alba L.
Acta Societatis Botanicorum Poloniae, 2014 After selfpollination of Sinapis alba L. pollen tubes growth is inhibited on the stigma. The pollen grains germinate 3-4 hours after pollination. The pollen give rise to one or more pollen tubes. They grow along the papillae.

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

Movement of Lipid Droplets in the Arabidopsis Pollen Tube Is Dependent on the Actomyosin System
Plants, 2023 The growth of pollen tubes, which depends on actin filaments, is pivotal for plant reproduction. Pharmacological experiments showed that while oryzalin and brefeldin A treatments had no significant effect on the lipid droplets (LDs) trafficking, while 2 ...
