A Fruitful Journey: Pollen Tube Navigation from Germination to Fertilization
Annual Review of Plant Biology, 2019In flowering plants, pollen tubes undergo tip growth to deliver two nonmotile sperm to the ovule where they fuse with an egg and central cell to achieve double fertilization.

Molecular Basis of Pollen Germination in Cereals
Trends in Plant Science, 2019Understanding the molecular basis of pollen germination in cereals holds great potential to improve yield. Pollen, a highly specialized haploid male gametophyte, transports sperm cells through a pollen tube to the female ovule for fertilization, directly determining grain yield in cereal crops.

Staining Germinating Pollen and Pollen Tubes
Stain Technology, 1958Germinating pollen on stigmas and pollen tubes in styles of Antirrhinum, Brassica, Oenothera, Raphanus, Rosa, solatium and Tagetes spp. were prepared for examination as follows: The styles were fixed in ethyl alcohol-acetic acid 3:1 for 1 hr, and hydrolyzed at 60°C for 5 to 60 min (depending on the species) in 45% acetic acid.

Grana, 1979
Abstract The pollen size variations seen among the cultivars of Ananas comosus (Bromeliaceae) and the differences seen in wall reticulations of A. comosus and A. bracteatus are recorded. Among the different cultivars the pollen viability was between 24–92% according to the peroxidase and acetocarmine tests.

RNA synthesis during pollen germination
Planta, 1971Regulation of pollen germination of Petunia was investigated by determining RNA content and composition in an in vitro system in the presence and absence of the transcription inhibitor actinomycin D and by labelling with C14-orotic acid.At the beginning of the progamic phase 2 stages can be distinguished: First (up to 15 minutes) no essential RNA ...

POLLEN GERMINATION AND TUBE GROWTH
Annual Review of Plant Physiology and Plant Molecular Biology, 1997▪ Abstract Many aspects of Angiosperm pollen germination and tube growth are discussed including mechanisms of dehydration and rehydration, in vitro germination, pollen coat compounds, the dynamic involvement of cytoskeletal elements (actin, microtubules), calcium ion fluxes, extracellular matrix elements (stylar arabinogalactan proteins), and control

Actin during pollen germination
Journal of Cell Science, 1986ABSTRACT The cytoplasm of the vegetative cell of the ungerminated pollen grain of Endymion non-scriptus and other angiosperm species contains numerous fusiform bodies sometimes exceeding 15 gm in length and 2-5 gm in width, which bind fluorescent-labelled phalloidin and are likely therefore to constitute a storage form of actin.

Pollen Germination and Pollen Tube Growth
2001Pollen, the male gametophyte of higher plants, is a biological system playing a central role in sexual plant reproduction (Cresti et al., 1992). The understanding of the mechanisms controlling the various aspects of pollen tube development has a direct relevance to biotechnological applications since it represents a starting point to modify crop ...
