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,

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 ...

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 ...

Pollen tube emergence is mediated by ovary-expressed ALCATRAZ in cucumber [PDF]

open access: yes, 2023
Pollen tube guidance within female tissues of flowering plants can be divided into preovular guidance, ovular guidance and a connecting stage called pollen tube emergence.

Nitric Oxide Participates in Aluminum-Stress-Induced Pollen Tube Growth Inhibition in Tea (Camelliasinensis) by Regulating CsALMTs

open access: yesPlants, 2022
Nitric oxide (NO), as a signal molecule, is involved in the mediation of heavy-metal-stress-induced physiological responses in plants. In this study, we investigated the effect of NO on Camellia sinensis pollen tubes exposed to aluminum (Al) stress ...

Immunofluorescence Labeling of Pollen Tubes

open access: yesBio-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.

Effect of boron toxicity on pollen tube cell wall architecture and the relationship of cell wall components of Castanea mollissima Blume

open access: yesFrontiers in Plant Science, 2022
Boron (B) is essential to plant development. However, excessive B is toxic to plants. This research was performed to evaluate the effects of B toxicity on cell wall architecture of Chinese chestnut (Castanea mollissima Blume) pollen tubes with emphasis ...

Toward in vitro fertilization in Brachiaria spp. [PDF]

open access: yes, 2010
Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

WD40-domain protein GORI is an integrative scaffold that is required for pollen tube growth in rice

open access: yesPlant Signaling & Behavior, 2023
The pollen tube plays a critical role in angiosperm plants by delivering sperm gametes for double fertilization. Although the molecular mechanisms underlying pollen tube germination and growth are crucial to crop plants, they are poorly understood. Here,

Effects of Alternaria alternata f.sp. lycopersici toxins on pollen [PDF]

open access: yes, 1988
Effects of the phytotoxic compounds (AAL-toxins) isolated from cell-free culture filtrates of Alternaria alternata f.sp. lycopersici on in vitro pollen development were studied. AAL-toxins inhibited both germination and tube growth of pollen from several
