The origin of domesticated Asian rice (Oryza sativa) has been a contentious topic, with conflicting evidence for either single or multiple domestication of this key crop species. We examined the evolutionary history of domesticated rice by analyzing de novo assembled genomes from domesticated rice and its wild progenitors. Our results indicate multiple origins, where each domesticated rice subp...

Lactococcus lactis subspecies lactis (L. lactis ssp. lactis) and Lactococcus lactis subspecies cremoris (L. lactis ssp. cremoris) were investigated in respect to their response to acid, bile-salt and freezing stresses. First, the sublethal and lethal levels of each stress were determined for both subspecies. For acid stress, the levels were pH 4.5 and 2.5, respectively, for L. lactis ssp. lacti...

We studied the role of neurokinin-1 receptors (NK1-R) on the excitability of expiratory (E) neurons (tonic discharge, E(TONIC); augmenting, E(AUG); decrementing, E(DEC)) throughout the ventral respiratory group, including Bötzinger Complex (BötC) using extracellular single-unit recording combined with pressurized picoejection in decerebrate, arterially perfused juvenile rats. Responses evoked b...

Session 4 Conventional and Novel Methodologies for Plant Improvement ABSTRACT Chromosomes of two diploid (2n=2x=16) subspecies of Medicago sativa, ssp. caerulea and ssp. falcata, their hybrid and tetraploid (2n=4x=32) cultivated alfalfa (M. sativa, ssp. sativa) were studied. Feulgen’s staining, Cand N-banding techniques and an image analysis system were used. The chromosomes of ssp. falcata hav...

C iência & Súde C otiva, 14(6)72-1982, 2009 territórios sustentáveis” e auxilia na construção de diretrizes políticas que atuem na determinação das relações entre produção, consumo, saúde e ambiente, possibilitando identificar, conforme as conclusões do autor, novas formas de organização da gestão coletiva da produção e do consumo que permitam um novo sentimento de existência para a vida humana.

Dear Sir, G antigen (Rh12) is expressed on red blood cells that carry D and/or C antigen1-3. Serine is the critical amino acid for G antigen expression. Anti-G can cause haemolytic disease of newborn, which is rare, but responsible for neonatal morbidity and mortality. However, Anti-G antibody is difficult to distinguish from anti-D in combination with anti-C. Accurate identification of these a...

Background: In current study, chemical composition and antibacterial activity of leaves and flowers essential oils of Origanum vulgare ssp. gracile against four food-borne pathogens including  Escherichia coli, Listeria monocytogenes, Salmonella thyphimurium and Staphylococcus aureus were examined. Methods: The different organs (leaves and flowers) of O. vulgare ssp. gracile were har...

The improvement of cold adaptation has contributed to the increased growing area rice. Standing variation and de novo mutation are distinct natural sources beneficial alleles in plant adaptation. However, genetic mechanisms evolutionary patterns underlying these a single population during crop domestication remain elusive. Here we cloned CTB2 gene, encoding UDP-glucose sterol glucosyltransferas...

As two kinds of solid wastes, waste tires and steel slag have caused serious threats to the environment. Both tire rubber (WTR) powder (SSP) can improve performance asphalt, while indexes modification mechanism modified asphalt are not clear. In this paper, with SSP WTR was prepared, its evaluated. The physical properties WTR, including penetration, softening point, viscosity, were investigated...
