BACKGROUND AND AIMS The aim of this work was the identification and molecular characterization of novel sugar beet (Beta vulgaris) repetitive sequences to unravel the impact of repetitive DNA on size and evolution of Beta genomes via amplification and diversification. METHODS Genomic DNA and a pool of B. vulgaris repetitive sequences were separately used as probes for a screening of high-dens...

Patterns of seed dispersal in the wild sea beet (Beta vulgaris ssp. maritima) are predicted to be influenced by marine currents because populations are widely distributed along the European Atlantic coast. We investigated the potential influence of marine currents on the pattern of spatial genetic structuring in natural populations of sea beet. Populations were located along the French coasts o...

A model of the migration pattern in a metapopulation of sea beet (Beta vulgaris L. ssp. maritima), based on the continuous distributions of seed and pollen movements, is fitted to gene frequency data at 12 isozyme and RFLP loci by maximum likelihood by using an approximation of the simultaneous equilibrium distribution of the gene frequencies generated by the underlying multivariate stochastic ...

A new species of eriophyoid mite, Aceria utzkae n. sp., inhabiting Carlina acanthifolia subsp. utzka (Hacq.) Meusel & Kästner (Asteraceae) is described and illustrated. It is compared with Aceria carlinae (Nalepa), the only other species known to inhabit Carlina spp., and a differential diagnosis is provided. Both species are recorded from Serbia for the first time and a new host plant, Carlina...

Chromium was not required for normal growth of romaine lettuce (Lactuca sativa L. subsp. longifolia), tomato (Lycopersicon esculentum Mill.), wheat (Triticum aestivum L.), or bean (Phaseolus vulgaris L.) in solution culture containing 3.8 x 10(-4) muM Cr. Plants grown on this purified nutrient solution contained an average of 22 ng Cr/g dry weight. Duckweed (Lemna sp.) grew and reproduced norma...

The objective of the present work was to evaluate the effect of exogenously applied cadmium on the physiological response of green algae Chlorella vulgaris. The study investigated the long-term effect (18 days) of cadmium on the levels of algae biomass, assimilation pigment composition, soluble protein, oxidative status (production of hydrogen peroxide and superoxide anion), antioxidant enzymes...

Objective: Medicinal plants have attracted global attention due to their safety as well as their considerable antioxidant content that helps to prevent or ameliorate various disorders including memory impairments. This study was conducted to investigate the effect of beet root (Beta vulgaris) leaf extract on scopolamine-induced spatial memory impairments in male Wistar rats. Materials and Metho...

OBJECTIVE To determine frequency of HLA-DR alleles in Pakistani patients of pemphigus vulgaris in comparison with local healthy controls. STUDY DESIGN Cross-sectional, comparative study. PLACE AND DURATION OF STUDY Department of Immunology, Armed Forces Institute of Pathology (AFIP), Rawalpindi, from January 2011 to January 2014. METHODOLOGY Twenty eight patients with biopsy proven diagno...

We have examined fine-scale genetic structure of the symbiotic ectomycorrhizal fungi Rhizopogon occidentalis and R. vulgaris on two of the California Channel Islands using five and six microsatellite loci, respectively. Both Rhizopogon species are sympatric on Santa Cruz and Santa Rosa Islands and are ectomycorrhizal with bishop pine (Pinus muricata) on both islands or Santa Rosa Island Torrey ...
