ABSTRACT Bee pollen has been used as a medicine and food supplement. The biological activity and nutrient composition of bee pollen depend on its floral origin. Therefore, it was aimed to determine the phenolic and flavonoid content and antibacterial activities of methanolic (99.9%) extract of bee pollens among flora. Floral origin was identified using

Usage of different xenobiotics, in particular ionizing radiation, for the modification of growth properties of pollen tubes is widely spread due to the possibility to apply gamma-irradiated pollen for mutagenesis and apomixis induction as well as ...

BackgroundAs in animals, cell–cell communication plays a pivotal role in male–female recognition during plant sexual reproduction. Prelaid peptides secreted from the female reproductive tissues guide pollen tubes towards ovules for fertilization. However,

PolSpec: Polarisation‐Based Detection for Versatile, Cost‐Effective Rapid Hyperspectral Imaging
“PolSpec” is a fast, flexible, data efficient and cost‐effective technique for hyperspectral imaging utilising polarisation‐based spectral modulation. Using data‐efficient representation of spectral information on vector plots, it facilitates rapid visualisation and segmentation of spectral contrast to classify sample features. As a proof of concept, a

Nitric oxide (NO) as a signaling molecule plays crucial roles in many abiotic stresses in plant development processes, including pollen tube growth. Here, the signaling networks dominated by NO during cold stress that inhibited Camellia sinensis pollen ...

Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth [PDF]
Background: Callose (β-1,3 glucan) separates developing pollen grains, preventing their underlying walls (exine) from fusing. The pollen tubes that transport sperm to female gametes also contain callose, both in their walls as well as in the plugs that ...

Molecular cloning and transcriptional activity of a new Petunia calreticulin gene involved in pistil transmitting tract maturation, progamic phase, and double fertilization [PDF]
Calreticulin (CRT) is a highly conserved and ubiquitously expressed Ca2+-binding protein in multicellular eukaryotes. As an endoplasmic reticulum-resident protein, CRT plays a key role in many cellular processes including Ca2+ storage and release ...

ABSTRACT The evolution of lakes in western Mongolia and their responses to climate changes and glacial meltwater input remain poorly understood. This study evaluates the reliability of multigrain and single‐grain K‐feldspar post‐infrared infrared stimulated luminescence (IRSL) (pIRIR) dating applied to palaeoshoreline sediments at Khyargas Nuur ...

Flowering and pollination studies with European plum (Prunus domestica L.) cultivars [PDF]
One of the most important factors affecting the financial outcome of commercial fruit growing is the success of pollination and fertilization, which in turn are dependent on weather conditions, activity of pollinators and the compatibility and overlap in
