We have analyzed the origin of cardiac progenitors in the zebrafish embryo by injection of single blastomeres with a lineage tracer dye, and examined the formation of the zebrafish heart tube by serial sectioning of immunostained embryos. At the 512-cell stage (early blastula), most cardiac progenitors lie in a marginal zone that extends from 90 degrees longitude (midway between the future dors...

We used mitochondrial DNA and microsatellite loci to examine the phylogeographic patterns of the most broadly distributed lizard in eastern North America, the five-lined skink (Eumeces fasciatus). We infer that longitudinal phylogeographic patterns in E. fasciatus are consistent with fragmentation due to refugial and post-glacial dynamics, but that deep divergences within the species imply hist...

the experiment was investigated to survey of yield and yield components of sunflower cultivars under drought stress in 2012 in kabootatabad of esfahan farm. an experiment was conducted in split plot and was designed in randomized complete block with three replications. irrigation was as main plots in 3 levels (control (normal irrigation), irrigation of 130 mm evaporation from pan evaporation, i...
