Whole‐genomic DNA amplifications from individually isolated sweet sorghum microspores

open access: yesApplications in Plant Sciences, Volume 10, Issue 6, November-December 2022., 2022
Abstract Premise Sorghum is a multi‐use crop, the efficient breeding of which requires the development of new genetic tools. One such tool could be the genetic assessment of free microspores, which are released just after the tetrad stage of pollen development.

Ethylene-independent signaling by the ethylene precursor ACC in Arabidopsis ovular pollen tube attraction

open access: yesNature Communications, 2020
The phytohormone ethylene has numerous effects on plant growth and development. Its immediate precursor, 1-aminocyclopropane-1-carboxylic acid (ACC), is a non-proteinogenic amino acid produced by ACC SYNTHASE (ACS).

Plasma membrane H+-ATPases sustain pollen tube growth and fertilization

open access: yesNature Communications, 2020
Pollen tubes are highly polarized tip-growing cells that depend on cytosolic pH gradients for signaling and growth. Autoinhibited plasma membrane proton (H+) ATPases (AHAs) have been proposed to energize pollen tube growth and underlie cell polarity ...

Annexin5 plays a vital role in Arabidopsis pollen development via Ca2+-dependent membrane trafficking. [PDF]

open access: yesPLoS ONE, 2014
The regulation of pollen development and pollen tube growth is a complicated biological process that is crucial for sexual reproduction in flowering plants.

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 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,

A Complex Journey: Cell Wall Remodeling, Interactions, and Integrity During Pollen Tube Growth

open access: yesFrontiers 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.

Rarity begets rarity: Social and environmental drivers of rare organisms in cities

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Cities are sometimes characterized as homogenous with species assemblages composed of abundant, generalist species having similar ecological functions. Under this assumption, rare species, or species observed infrequently, would have especially high conservation value in cities for their potential to increase functional diversity.

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 ...
