In order to study the genetic and environmental variability of morphological and phenological characteristics and also to gain a better understanding of the morphological basis of yield variation in soybean, an experiment was conducted at Research Farm, College of Agric., Isfahan University of Technology, in 1996. The experiment was arranged in three augmented designs with 285 lines and 5 contr...

In this study, Simple Sequence Repeat markers (SSR) were used to investigate the genetic variation between 49 cumin ecotypes collected from 9 different provinces of Iran. SSR primers Elap1479, Elap040 and Elap1493 showed the highest (89%), while Elap1340 and Elap017 showed the lowest (56%) number of polymorphic bands. Polymorphism information content (PIC) values varied between 0.18 - 0.37. The...

A study was undertaken to evaluate the genetic variation in the 10th generation of a breeder flock of native breed selected for high egg and meat production in native fowls breeding station, Mazandaran, Iran. Venous blood samples were collected from 100 birds of both sexes. The RAPD-PCR technique was applied to generate a DNA fingerprint of individuals. Initially, a total of 20 ten-nucleotide a...

n engl j med 367;14 nejm.org october 4, 2012 1350 an adjusted multivariate model showed similar nonsignificant results. Finally, favorable trends with IABP were observed in younger patients and in those with a first myocardial infarction, although these findings can be considered only as hypothesis-generating. Given the concordance of data from the meta-analyses and the current trial, the data ...

Splicing sites provide unique statistics in human genome due to their large number and reasonably complete annotation. Analyses of the cumulative SNPs distribution in splicing sites reveal a few interesting observations. While a degree of the nucleotide conservation reflects on the SNPs density monotonically, no detectable changes in the SNPs frequencies spectrum were found. Semi-conserved nucl...

Halobacterium halobium exhibits an extraordinary degree of spontaneous variability. Mutants which are defective in the formation of gas vacuoles (vac) arise at a frequency of 10(-2). Other easily detectable phenotypes, like the synthesis of bacterioruberin (Rub) or the synthesis of retinal (Ret) and bacterio-opsin (Ops), the two components which form the purple membrane (Pum) of H. halobium, ar...
