Bio‐inspired nanophotonics: Structural color, chirality, and resonance metasurfaces
InfoMat, EarlyView.A butterfly‐wing‐inspired anisotropic plasmonic flatband resonant metasurface. Insets, photo of the butterfly, Sasakia charonda, and the SEM image of its wing scale (above); the SEM image of the metasurface (below). Abstract The dazzling colors of butterfly wings and hummingbird feathers are not painted with pigments, but crafted by nature's invisible ...

Air investigation of some alternative methods to agrobacterium and protoplast transformation for introducing exogenous genes into plants, based on the use of pollen as a vector [PDF]
, 1987 Some of the problems involved in the search for alternative plant transformation vectors have been examined. In particular the use of pregerminated pollen as a direct transformation vector has been investigated.

Journal of Applied Toxicology, EarlyView.ABSTRACT Aristolochia species have long been used in traditional medicine for their presumed anti‐inflammatory, analgesic and antimicrobial properties. However, extensive toxicological and epidemiological evidence now demonstrates that these plants contain aristolochic acids (AAs) I and II, highly potent nephrotoxic, genotoxic, and carcinogenic ...

Analysis of airborne pollen grains in Kirklareli
, 2011 A continuous aeropalynological survey of the atmosphere of Kirklareli was carried out from January 2002 to December 2003 by means of the gravimetric method using Durham apparatus. Weekly pollen grains in per cm(2) were calculated. During these 2 years, a

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.

Труды по прикладной ботанике, генетике и селекции, 2019 Background. In breeding work, it is necessary to take into account such an important feature as male sterility of the hybrids obtained. If a plant has visually visible anthers and pollen, the quality of the pollen grains themselves may be low.

Decoupling climate and human impacts on the nitrogen cycle during the Irish Bronze Age
Journal of Quaternary Science, EarlyView.ABSTRACT Disentangling climate variability and human activity in past nitrogen cycling is key to understanding ecosystems. Previous studies in Ireland observed a widespread, permanent shift in terrestrial nitrogen cycling during Later Prehistory, potentially linked to intensifying land‐use.
