BACKGROUND Various proteins that display carbohydrate-binding activity in a Ca(2+)-dependent manner are classified into the C-type lectin family. They have one or two C-type carbohydrate-recognition domains (CRDs) composed of 110-130 amino acid residues in common. C-type lectins mediate cell adhesion, non-self recognition, and immuno-protection processes in immune responses and thus play signif...

The monotypic genera Epiplagiops Blanchard, 1943 and Tetragrapha Brauer and Bergenstamm, 1891 are revised. Both are invalidated and synonymized with Chetogena Rondani, 1856. Their type-species, Epiplagiops littoralis Blanchard, 1943 and Tetragrapha tessellata Brauer and Bergenstamm, 1891, are studied, redescribed, illustrated, and transferred to Chetogena. A lectotype is designated for T. tesse...

From the water-soluble portion of the methanol extract of the fruit of Glehnia littoralis Fr. SCHMIDT ex MIQ. (Umbelliferae; "hamabofu" in Japanese), thirty compounds, including three new monoterpenoids and a new monoterpenoid glucoside, a new benzofuran glucoside, a new alkyl glucoside, and a new glucide, were obtained. Their structures were clarified by spectral investigation.

Bacillus thuringiensis insecticidal crystal proteins (ICPs) are thought to induce pore formation in midgut cell membranes of susceptible insects. Cry1Ca, which is significantly active in Spodoptera littoralis, made brush border membrane vesicles permeable to KCl (osmotic swelling was monitored by the light scattering technique); the marginally active ICPs Cry1Aa, Cry1Ab, and Cry1Ac did not.

Background: We describe karyotypic variations and the in vitro methods for plant propagation and conservation as well as detailed chromosomal analysis of (Aloe vera L.) and Aloe littoralis from Iran during flowering stage. Objectives: This karyotypic was discovered because of a difference in the position of the chromosome and due to genomic differentiation in domesticated pop...

Plants activate local and systemic defence mechanisms upon exposure to stress. This innate immune response is partially regulated by plant hormones, and involves the accumulation of defensive metabolites. Although local defence reactions to herbivores are well studied, less is known about the impact of root herbivory on shoot defence. Here, we examined the effects of belowground infestation by ...

Although knowledge on dispersal patterns is essential for predicting long-term population dynamics, critical information on the modalities of passive dispersal and potential interactions between vectors is often missing. Here, we use mangrove propagules with a wide variety of morphologies to investigate the interaction between water and wind as a driver of passive dispersal. We imposed 16 combi...

Abstract The need to respond quickly the presence of an ephemeral resource required for breeding is often a feature scramble competition mating systems. Scramble systems can extreme levels sexual conflict and coercive by males. As result, selection act on various traits used males overcome female resistance behaviours. Selection these may result in significant intra intersexual size variation d...

Freshwater mussels are among the most endangered groups of fauna anywhere in world. The indiscriminate use antibiotics has led to emergence resistant strains. These antibiotic-resistant bacteria play a key role increasing risk allied with surface water and spread resistance genes. Two freshwater mussel species, Margaritifera margaritifera Potomida littoralis, were sampled at 4 sampling sites al...
