Intraspecific divergence in floral-tube length promotes asymmetric pollen movement and reproductive isolation.

New Phytologist, 2019
The causative link between phenotypic divergence and reproductive isolation is an important but poorly understood part of ecological speciation. We studied the effects of floral-tube length variation on pollen placement/receipt positions and reproductive

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

JSFA 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 ...

Pollen Grains and Tubes ☆

, 2017
A knowledge of pollen functions and its development in the genus Rosa is often of the greatest importance to the rose breeders and scientists when planning a hybridization program and research. The following paragraphs, therefore, brings together all the available scientific information from pollen formation to fertilization and its management.

Rapid, simple and accessible phytonutritional assessment methods in agricultural research

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Agricultural research with respect to studying the effects of genetic background and environmental conditions on plant and commercial parameters is ample. Nevertheless, data on the effects on nutritional value and phytonutritional composition are scarce, despite its significance to the consumer, as well as its importance in ...

Arabidopsis COG Complex Subunits COG3 and COG8 Modulate Golgi Morphology, Vesicle Trafficking Homeostasis and Are Essential for Pollen Tube Growth

PLoS Genetics, 2016
Spatially and temporally regulated membrane trafficking events incorporate membrane and cell wall materials into the pollen tube apex and are believed to underlie the rapid pollen tube growth.

In search of ligands and receptors of the pollen tube: the missing link in pollen tube perception

Biochemical Society Transactions, 2014
The journey undertaken by the pollen tube in angiosperms to reach the deeply embedded female gametophyte for fertilization involves persistent guidance by the female gametophyte and accurate perception of the signals by the pollen tube. Several ovule-secreted peptides have been identified.

Oral Administration of Trichosanthes Kirilowii Fruit Extract Ameliorates Airway Inflammation and Suppresses Th2 Cell Activities in Ovalbumin‐Sensitized Mice

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Trichosanthes kirilowii is a plant used in traditional Chinese medicine. Its fruits, seeds, and roots can all be used medicinally. The fruit of T. kirilowii has a moistening effect on the lung for arresting cough. However, there is no scientific research to prove that the fruit of T. kirilowii can improve asthma. Herein, we evaluated whether T.

Massively Parallelized Pollen Tube Guidance and Mechanical Measurements on a Lab-on-a-Chip Platform

PLoS ONE, 2016
Pollen tubes are used as a model in the study of plant morphogenesis, cellular differentiation, cell wall biochemistry, biomechanics, and intra- and intercellular signaling. For a “systems-understanding” of the bio-chemo-mechanics of tip-polarized growth

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

Nordic Journal of Botany, EarlyView.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Developmental transcriptomes predict adult social behaviours in the socially flexible sweat bee, Lasioglossum baleicum

Molecular Ecology, EarlyView., 2023
Abstract Natural variation can provide important insights into the genetic and environmental factors that shape social behaviour and its evolution. The sweat bee, Lasioglossum baleicum, is a socially flexible bee capable of producing both solitary and eusocial nests.
