Pollination, Fertilization, and Embryo Development in Southern China Fresh-eating Jujube

open access: yesHortScience, 2020
To explore the reasons for seed abortion in southern China fresh-eating jujube, improve its reproductive biology, and provide a theoretical basis for the crossbreeding of jujube, we carried out self-pollination and cross-pollination experiments with ...

AGC1.5 Kinase Phosphorylates RopGEFs to Control Pollen Tube Growth.

open access: yesMolecular Plant, 2018
Double fertilization in angiosperms requires the targeted delivery of immotile sperm to the eggs through pollen tubes. The polarity of tip-growing pollen tubes is maintained through dynamic association of active Rho GTPases of plants (ROP-GTP) with the ...

Integrated characterization of Greek fennel genotypes through morpho‐agronomical characteristics, yield components and phytochemical compounds

open access: yesJSFA reports, Volume 5, Issue 3, Page 91-103, March 2025.
Abstract Background Fennel (Foeniculum vulgare Mill.) is a widely cultivated vegetable and aromatic‐medicinal plant. In this research, field studies assessed 12 fennel genotypes of diverse origin, comprising 10 Greek accessions and two European commercial varieties, focusing on their morpho‐agronomical traits, phenolic compounds and antioxidant ...

A calcium-dependent protein kinase, ZmCPK32, specifically expressed in maize pollen to regulate pollen tube growth.

open access: yesPLoS ONE, 2018
Calcium-dependent protein kinases (CPKs) play an essential role in the regulation of pollen tube growth. Although CPK genes have been identified in maize, and some have been functionally characterized, the molecular function of ZmCPKs associated with ...

Calcium: A Critical Factor in Pollen Germination and Tube Elongation

open access: yesInternational Journal of Molecular Sciences, 2019
Pollen is the male gametophyte of higher plants. Its major function is to deliver sperm cells to the ovule to ensure successful fertilization. During this process, many interactions occur among pollen tubes and pistil cells and tissues, and calcium ion ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

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

open access: yesJournal of Agricultural Sciences (Belgrade), 2014
The study was carried out to determine the effect of three different temperatures (5, 15 and 25°C) on in vitro pollen germination and pollen tube growth of five sour cherry cultivars: ‘Heimanns Konservenweichsel’, ‘Kelleriis 14’, ‘Oblačinska ...

ANTH domain-containing proteins are required for the pollen tube plasma membrane integrity via recycling ANXUR kinases

open access: yesCommunications Biology, 2018
During plant reproduction, sperm cells are delivered to ovules through growing pollen tubes. This process involves tip-localized receptor kinases regulating integrity and/or guidance of pollen tubes, whose localizations must be strictly regulated ...

Reinstatement of the name Anisochilus eriocephalus Benth. (Lamiaceae) supported by micromorphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
In 2019, A. J. Paton et al. proposed a new taxonomic combination, transferring Anisochilus carnosus (L.f.) Wall. ex Benth. to Coleus strobilifer (Benth.) A.J.Paton, and including Anisochilus eriocephalus Benth. within this broader circumscription.
