Calycanthus chinensis: The Chinese Sweetshrub
are oppositely arranged with short petioles and are glossy green with a touch of roughness on the upper surface. In the Boston area its nodding flowers appear in mid to late spring. Appearances notwithstanding, the sepals and petals are not differentiated (therefore termed tepals): the outer tepals are a silky white with a tinge of pink and a diameter of two to three inches, while the inner tep...
متن کاملThe Genetic Structure of Natural Populations
Recent reports (MUKAI et al. 1974; KATZ and CARDELLINO 1978; COCKERHAM and MUEAI 1978) have indicated that the Cy chromosome is not always dominant over its homologous chromosome with respect to viability. Thus, the genetic parameters previously estimated using viabilities determined by the Cy method are biased. In the present paper, the biases of the estimates for the polygenic mutation rate, ...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولCharacterization of 31 microsatellite markers for Sinocalycanthus chinensis (Calycanthaceae), an endemic endangered species1
PREMISE OF THE STUDY Thirty-one microsatellite markers were developed for Sinocalycanthus chinensis (Calycanthaceae), an endemic endangered species in China. METHODS AND RESULTS Twenty-one polymorphic and 10 monomorphic microsatellite markers of S. chinensis were developed using methods of biotin-streptavidin capture and capillary electrophoresis. The number of alleles per locus was one to 20...
متن کاملMultilocus genetic structure in natural populations of Escherichia coli.
A survey of allozyme variation at 12 enzyme loci in 1,705 clones of the genetic species Escherichia coli (including four species of Shigella) from natural populations revealed 302 unique allele combinations (electrophoretic types). Single-locus diversity estimates fall within the range predicted by the neutral allele theory of molecular evolution, but the combination of alleles in electrophoret...
