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.

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 ...

Comparative pollen morphology of Calycanthaceae for their taxonomic implication

European Journal of Biological Research, 2020
The pollen morphology of four species of Calycanthaceae is described based on the observation of scanning electron microscopy and light microscopy. All pollens are monad, large grain category. The pollen grain was elliptic with disulcate.

Iron Age to Medieval entomogamous vegetation and Rhinolophus hipposideros roost in south-eastern Wales (UK) [PDF]

, 2006
Karst cave systems are well developed in Wales (UK) and, in some instances, constitute important bat roosts. Ogof Draenen, near Blaenavon in south-east Wales, is the most recent major cave discovery (1994) with already > 70 km of passages explored ...

Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute [PDF]

, 2018
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new alternatives for managing soil ...

Callose plug deposition patterns vary in pollen tubes of Arabidopsis thaliana ecotypes and tomato species

BMC Plant Biology, 2012
Background The pollen grain contains the male gametophyte that extends a pollen tube that grows through female tissues in order to deliver sperm to the embryo sac for double fertilization. Growing pollen tubes form periodic callose plugs that are thought
