Infection mechanisms of Rhizoctonia cerealis in wheat

iMeta, EarlyView.
We discover that R. cerealis (Rc) is a primary pathogen causing sharp eyespot of wheat after 335 distinct isolates were isolated from 1683 SE‐diseased wheat plants across China over 7 years using a single hyphal tip isolation method. We then generated high‐quality reference genomes via de novo sequencing of five representative Rc isolates and ...

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-

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.

Fatty acid composition of pollen and the effect of two dominant fatty acids (linoleic and oleic) in pollen and flour diets on longevity and nutritional composition of honey bees (apis mellifera) [PDF]

, 2006
The size of the apiculture industry in Western Australia (W.A.) is one of the smallest in the nation but the production of pollen and honey per colony is the highest in Australia.

Pollen Morphology of Crucianella L. (Rubiaceae) Based on Light and Scanning Electron Microscope Data and Implications for Taxonomy

Microscopy Research and Technique, EarlyView.
This study provides the palynological analysis of 12 Crucianella L. taxa using LM and SEM. Variations in pollen size, aperture number, and exine ornamentation were identified as key traits, demonstrating their taxonomic value for distinguishing closely related species and subspecies within the genus. ABSTRACT Crucianella L.

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Holocene vegetation change and fire–plant diversity shifts in Mediterranean France

Journal of Quaternary Science, EarlyView.
ABSTRACT Changes in fire activity are recognized as a major threat to biodiversity and vegetation communities across the Mediterranean Basin. However, long‐term fire–vegetation interactions remain poorly investigated. Here, we combine a high‐resolution charcoal record with pollen data from the “Étang des Aulnes” lake (southern France) to reconstruct ...

Image analysis in automatic system of pollen recognition

Acta Agrobotanica, 2012
In allergology practice and research, it would be convenient to receive pollen identification and monitoring results in much shorter time than it comes from human identification.
