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 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 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,

Cell Wall Composition, Biosynthesis and Remodeling during Pollen Tube Growth
Plants, 2013 The pollen tube is a fast tip-growing cell carrying the two sperm cells to the ovule allowing the double fertilization process and seed setting. To succeed in this process, the spatial and temporal controls of pollen tube growth within the female organ ...

ROS in the Male–Female Interactions During Pollination: Function and Regulation
Frontiers in Plant Science, 2020 The male–female interactions in pollination mediate pollen hydration and germination, pollen tube growth and fertilization. Reactive oxygen species (ROS) derived from both male and female tissues play regulatory roles for the communication between the ...

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 ...

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.

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.

POLLEN TUBE GROWTH IN MANDARIN
Revista Fitotecnia Mexicana, 2022 Pollen tube growth was studied in cvs. Monica, Reyna, Dancy, and Satsuma mandarin (Citrus reticulata unshiu Marc). Pollen tubes were stained with lacmoid and observed with a white light microscope. Lacmoid stained the callose brilliant blue. Pollen grains deposited on the stigma varied from 367 to 4170 among the four cultivars.
