Variation in leaf characters of Parrotia persica in relation to their position in the canopy along an altitudinal gradient were studied. Genetic and phenotypic characters make P. persica one of the most noteworthy plants in the five floristic regions of Iran. It is an endemic species of the Hyrcanian forests, and occurs naturally from sea level to over 900 m a.s.l. on the north side of the Mountain Ranges of Alborz, northern Iran. There was a significant effect of altitude only on few leaf features [width of lamina, base angle (internal angle of lamina), number of pair vein (number of principal veins of lamina) of leaf, top and end of leaf figure]. Among different geographical sides of the crown, there was no significant difference in the plasticity of leaf features, but leaf figure (both top of leaf figure and end of leaf figure) showed the lowest plasticity among the different leaf characters. Of all characters measured, the lowest plasticity among the three populations was found for base angle and number of vein pairs. A PCA analysis showed that leaf petiole and maximum width of lamina in 0.9 of its length, together with leaf figure and width of lamina, accounted for the greatest variation in difference of populations. 相似文献

Autosomal recessive gene defects are arguably the most important, but least studied genetic causes of severe cognitive dysfunction.
Homozygosity mapping in 78 consanguineous Iranian families with nonsyndromic autosomal recessive mental retardation (NS-ARMR)
has enabled us to determine the chromosomal localization of at least 8 novel gene loci for this condition. Our data suggest
that in the Iranian population NS-ARMR is very heterogeneous, and they argue against the existence of frequent gene defects
that account for more than a few percent of the cases.

Isolation murine mesenchymal stem cells by positive selection 总被引:2,自引:0,他引:2
Isolation and purification of mesenchymal stem cells (MSCs) from mouse via plastic adherent cultures is arduous because of
the unwanted growth of hematopoietic cells and non-MSCs. In this work, homogenous populations of CD34+ MSCs from mouse bone marrow were isolated via positive selection. For this purpose, C57Bl/6 mice were killed and bone marrow
cells were aspirated before incubation with magnetic bead conjugated to anti-CD34 antibody. A sample of positively selected
CD34+ cells were prepared for flow cytometry to examine the expression of CD34 antigen and others were subcultured in a 25-cm2 culture flask. To investigate the mesenchymal nature, the plastic adherent cultivated cells were induced to differentiate
along osteoblastic and adipogenic lineages. Furthermore, the expression of some surface markers was investigated by flow cytometry.
According to the result, purified populations of fibroblast-like CD34+ cells were achieved in the first passage (1 wk after culture initiation). The cells expressed CD34, CD44, Sca-1, and Vcam-1
antigens (markers) but not CD11b and CD45. They were capable of differentiating into osteocytes and adipocytes. This study
indicated that our protocol can result in the efficient isolation of homogenous populations of MSCs from C57BL/6 mouse bone
marrow. We have shown that murine bone marrow-derived CD34+ cells with plastic adherent properties and capability of differentiating into skeletal lineages in vitro are MSCs. 相似文献

Methods for haplotyping and DNA copy-number typing of single cells are paramount for studying genomic heterogeneity and enabling genetic diagnosis. Before analyzing the DNA of a single cell by microarray or next-generation sequencing, a whole-genome amplification (WGA) process is required, but it substantially distorts the frequency and composition of the cell’s alleles. As a consequence, haplotyping methods suffer from error-prone discrete SNP genotypes (AA, AB, BB) and DNA copy-number profiling remains difficult because true DNA copy-number aberrations have to be discriminated from WGA artifacts. Here, we developed a single-cell genome analysis method that reconstructs genome-wide haplotype architectures as well as the copy-number and segregational origin of those haplotypes by employing phased parental genotypes and deciphering WGA-distorted SNP B-allele fractions via a process we coin haplarithmisis. We demonstrate that the method can be applied as a generic method for preimplantation genetic diagnosis on single cells biopsied from human embryos, enabling diagnosis of disease alleles genome wide as well as numerical and structural chromosomal anomalies. Moreover, meiotic segregation errors can be distinguished from mitotic ones. 相似文献
