Use of morphoj soft package for phenotypic and genotypic variety testing (English oak case study)
Abstract
Summary: Background. Some special characters in asymmetry of shape were studied in leaf plate English oak. Materials and methods. In 6 random populations generalized Procrustes analysis showed the mix of fluctuating asymmetry (FA) and directional asymmetry (DA). Results. One population showed pure FA. Covariance symmetric matrix reveals more variance in comparison to matrix asymmetry showed variation bilaterally symmetrical landmarks. Correlation analysis of covariance symmetric matrix and matrix asymmetry containing the coordinates of landmarks after the permutation showed a weak positive correlation coefficient (0.25, p < 0.01). Conclusion. The coefficients of variation of the factors “side”and “side × population” among 6 populations were respectively 48.24% and 44.93% that evidenced on equal variance of both types of asymmetry or slightly increased directional asymmetry. It is noted that the cluster analysis the matrix asymmetry can be used to search genotypic variability.
The evolution of ideas on the biological role of 5-methylcytosine oxidative derivatives in the mammalian genome
Abstract
Summary: In this review, we summarize data on 5-hydroxymethylcytosine, 5-formylcytosine and 5-carboxylcytosine – cytosine modifications which are produced by TET-mediated oxidation of 5-methylcytosine in DNA. We show the biochemistry of modified cytosine as well as methods for its global and location analysis. We also highlight the milestones in the evolution of ideas on the biological role of 5-hydroxymethylcytosine, 5-formylcytosine and 5-carboxylcytosine in the mammalian genome since their discovery in 2009 till present.
Functional analysis of cT-DNAs in naturally transformed plants, recent findings and general considerations
Abstract
Genetically modified organisms authorized for cultivation and breeding in Russia
Abstract
Summary: In July 2016 the State Duma adopted the Federal Law “On Amendments to Certain Legislative Acts of the Russian Federation in terms of improving the state regulation in the field of genetic engineering” (03.07.2016 N 358-FL). This review is devoted to the analysis of Article 4 of the Act, namely the discussion of what GMOs may be authorized for cultivation and breeding in Russia.
