Arguably, bacteriocins deployed in warfare among related bacteria are among the most diverse proteinacous compounds with respect to structure and mode of action. Identification of the first prokaryotic member of the so-called MMBLs (monocot mannose-binding lectins) or GNA (Galanthus nivalis agglutinin) lectin family and discovery of its genus-specific killer activity in the Gram-negative bacter...

Adults of the common green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), are prevalent pollen-consumers in maize fields. They are therefore exposed to insecticidal proteins expressed in the pollen of insect-resistant, genetically engineered maize varieties expressing Cry proteins derived from Bacillus thuringiensis (Bt). Laboratory experiments were conducted to evaluate the...

Abstract. The Satanivska Dacha tract in Khmelnytskyi Oblast, Ukraine, is unique that Fagus sylvatica L. grows here at the edge of its geographic range. In 2017, forest community was included trans-European World Heritage site ‘Primeval beech forests and ancient Carpathians other regions Europe" by UNESCO under name Site No. 61 ‘Satan’s Dacha.’ territory tract, 163 species vertebrates have been ...

We describe spectral reflectance measurements of snow containing the snow alga Chlamydomonas nivalis and a model to retrieve snow algal concentrations from airborne imaging spectrometer data. Because cells of C. nivalis absorb at specific wavelengths in regions indicative of carotenoids (astaxanthin esters, lutein, beta-carotene) and chlorophylls a and b, the spectral signature of snow containi...

BACKGROUND Dendritic cells (DC), present in the skin, are the first target cells of dengue virus (DENV). Dendritic cell-specific intercellular adhesion molecule 3-grabbing non-integrin (DC-SIGN) is present on DC and recognizes N-glycosylation sites on the E-glycoprotein of DENV. Thus, the DC-SIGN/E-glycoprotein interaction can be considered as an important target for inhibitors of viral replica...

Cotesia flavipes (Cameron) is a parasitoid responsible for maintaining populations of sugarcane borer, Diatraea saccharalis (F.), below economic levels in south Texas sugarcane Þelds. Transgenic sugarcane expressing the snowdrop lectin (Galanthus nivalis agglutinin, GNA) was developed against the Mexican rice borer, Eoreuma loftini (Dyar), the primary pest of south Texas sugarcane. The potentia...

The presence of Chionomys nivalis (Martins, 1842) (Mammalia Rodentia Cricetidae) in Calabria, the southern tip of the Italian peninsula, is reported in different literature sources, but the only Calabrian specimen, from Lago Cecita, Cosenza district, is preserved into Museo Zoologico “La Specola”, Firenze. A recent examination of this specimen, moreover, has shown that it is an Arvicola amphibi...
