Cytological effects of Dimethoate and Lambda-Cyhalothrin on Pollen Grain Cells Reproduction and Development

UMYU Journal of Microbiology Research
This study investigates the effects of Dimethoate (A) and Lambda-Cyhalothrin (B) on pollen grain cells in the soil at various concentrations. Lowest exine thickness was observed in soil treated with a combination of Dimethoate and Lambda-Cyhalothrin (A ...

Relationship between nuclear DNA-content of sperm cells and the timing of events in the cell cycle of Brassica campestris L. (Brassicaceae)

International Journal of Plant Biology, 2016
In this work we conducted a quantitative analysis of the nuclear DNA-content of developing sperm cells of the plant Brassica campestris L. The sperm cells were in young pollen grain, mature pollen grain and pollen tubes. When generative cells, at the pre-

Potential of Bee Pollen as a Nutraceutical And/Or Functional Ingredient for Metabolic Syndrome Management: In Vitro Antioxidant, Anti‐Inflammatory, and Digestive Enzyme Inhibitory Activities

Food Chemistry International, EarlyView.
Bee pollen samples from China and Spain exhibited in vitro antioxidant, anti‐inflammatory, and digestive enzyme inhibitory activities due to their composition, suggesting their potential as a nutraceutical or functional ingredient to help counteract oxidative stress, chronic inflammation, and metabolic disorders.

Genetically modified crops do not present variations in pollen viability and morphology when compared to their conventional counterparts.

PLoS ONE, 2023
Modern agricultural biotechnologies, such as those derived from genetic modification, are solutions that can enable an increase in food production, lead to more efficient use of natural resources, and promote environmental impact reduction.

A high resolution palynological study of the Holocene vegetational development of central Holderness, eastern Yorkshire, with particular emphasis on the detection of prehistoric human activity. [PDF]

, 2000
Compared to upland areas and Scotland, the Holocene vegetational history of lowland England is poorly known. This is particularly the case for the region of Holdemess, eastern Yorkshire, where only a low number of poor temporal resolution pollen diagrams

Combining phenotypic, physiological, and multi‐omics studies to provide new insights on the role of 2,4‐epibrassinolide in regulation of seed shattering in Elymus sibiricus L.

Grassland Research, EarlyView.
Abstract Background Seed shattering limits the production of Elymus sibiricus L., and application of exogenous brassinosteroid significantly alleviates plant organ abscission. Methods To explore the potential regulatory network of brassinosteroid on seed shattering, the abscission zone of E. sibiricus cv. Lanyu No.
