Pollen Germination and Tube Growth in Northern Highbush Blueberry are Inhibited by Extreme Heat
HortScience, 2023 The increasing intensity and frequency of extreme heat events threaten crop productivity globally. Certain phases of plant reproduction necessary for fertilization are highly sensitive to extreme heat, particularly during pollen development, germination,

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 [...]

Nitric oxide participates in cold-inhibited Camellia sinensis pollen germination and tube growth partly via cGMP in vitro. [PDF]
PLoS ONE, 2012 Nitric oxide (NO) plays essential roles in many biotic and abiotic stresses in plant development procedures, including pollen tube growth. Here, effects of NO on cold stress inhibited pollen germination and tube growth in Camellia sinensis were ...

Kanamycin resistance during in vitro development of pollen from transgenic tomato plants [PDF]
, 1987 Effects of kanamycin on pollen germination and tube growth of pollen from non-transformed plants and from transgenic tomato plants containing a chimaeric kanamycin resistance gene were determined. Germination of pollen was not affected by the addition of

A Complex Journey: Cell Wall Remodeling, Interactions, and Integrity During Pollen Tube Growth
Frontiers in Plant Science, 2020 In flowering plants, pollen tubes undergo a journey that starts in the stigma and ends in the ovule with the delivery of the sperm cells to achieve double fertilization.

Immunofluorescence Labeling of Pollen Tubes
Bio-Protocol, 2014 Pollen tube is regarded as an excellent single-cell model system in plant cell studies. This protocol describes the use of a rapid and reliable immunofluorescence labeling method for studying in situ localization of proteins in pollen tubes.

An extracellular transglutaminase is required for apple pollen tube growth [PDF]
, 2010 An extracellular form of the calcium-dependent protein-crosslinking enzyme TGase (transglutaminase) was demonstrated to be involved in the apical growth of Malus domestica pollen tube.

New Phytologist, 1989 summaryThis review considers pollen tube growth with regard to current information on pollen tube cytoplasm, wall structure and calcium ion interactions with pollen tubes. Pollen tubes have a marked cytoplasmic Polarity with a number of distinct zones along the tube, each with a characteristic complement of cytoplasmic and nuclear structures.
