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

Plant 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]

, 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

Effect of sucrose on in-vitro pollen germination of Gloriosa superba L. - a medicinal plant from the Garhwal Himalaya, India

Environment Conservation Journal, 2017
Pollen germination and pollen tube growth are prerequisites for fertilization in seed bearing plants. The present study deals with the morphology, production, pollen-ovule ratio, and effect of sucrose on in-vitro germination of pollen grains of Gloriosa ...

Longevity and germination of Juniperus communis L. pollen after storage

Scientific Reports, 2021
Pollen storage belongs among the most important activities associated with pollen handling. It overcomes the differences in pollen shedding and ovule receptivity during controlled pollination experiments.

Determination of cardinal temperatures for sugar apple ( Annona squamosa L.)

Ciência e Agrotecnologia, 2016
The sugar apple is highly dependent on the pollination and fruit tree pollen performance is crucial for successful fertilization and fruit set. The objective of this study was to determine the cardinal temperatures for in vitro pollen grains germination ...

Gelechiidae Moths Are Capable of Chemically Dissolving the Pollen of Their Host Plants [PDF]

, 2011
Background: Many insects feed on pollen surface lipids and contents accessible through the germination pores. Pollen walls, however, are not broken down because they consist of sporopollenin and are highly resistant to physical and enzymatic damage. Here

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 ...

Comparative Metabolic Analysis Reveals a Metabolic Switch in Mature, Hydrated, and Germinated Pollen in Arabidopsis thaliana

Frontiers in Plant Science, 2022
Pollen germination is an essential process for pollen tube growth, pollination, and therefore seed production in flowering plants, and it requires energy either from remobilization of stored carbon sources, such as lipids and starches, or from secreted ...
