The effect of temperature on pollen germination and pollen tube growth of pear cultivars [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2016
The effect of three different temperatures (8, 16 and 24°C) on pollen germination and length of pollen tube in vitro was investigated in four pear cultivars (‘Butirra Precoce Morettini’, ‘Williams’, ‘Conference’ and ‘Abate Fetel’).

The Arabidopsis GPI-anchored protein COBL11 is necessary for regulating pollen tube integrity

open access: yesCell Reports, 2023
Summary: Pollen tube integrity is required for achieving double fertilization in angiosperms. The rapid alkalinization factor4/19-ANXUR1/2-Buddha’s paper seal 1/2 (RALF4/19-ANX1/2-BUPS1/2)-complex-mediated signaling pathway is critical to maintain pollen

Pollen Tube and Plant Reproduction [PDF]

open access: yesInternational 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 [...]

ROS in the Male–Female Interactions During Pollination: Function and Regulation

open access: yesFrontiers 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 ...

Pollen Germination and Pollen Tube Growth in Gymnosperms [PDF]

open access: yesPlants, 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 ...

Pollen Germination and Tube Growth in Northern Highbush Blueberry are Inhibited by Extreme Heat

open access: yesHortScience, 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,

Durotropic Growth of Pollen Tubes [PDF]

open access: yesPlant 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.

Cell Wall Composition, Biosynthesis and Remodeling during Pollen Tube Growth

open access: yesPlants, 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 ...

Nitric oxide participates in cold-inhibited Camellia sinensis pollen germination and tube growth partly via cGMP in vitro. [PDF]

open access: yesPLoS 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 ...
