Purpose. Studying the peculiarities of the genetic structure of different age groups of silver and bighead carps from fish farm Limanske with the use of genetic-biochemical markers. Methodology. The ...methods of vertical polyacrylamide and horizontal starch electrophoresis with our own modifications have been used for the study. Sampling of the biological material and histochemical staining of gel plates were carried out using the generally accepted methods. Statistical analysis of the obtained data were performed in "Biosys-I". Findings. We analyzed the genetic structure of age-1, age-1+ and age-2 of silver and bighead carps with the use of genetic-biochemical markers - Рralb, EST, MDH, МЕ, СА. We demonstrated the peculiarities of allele frequencies and genotypic composition of protein system loci. A high level of heterozygosity in the examined was detected loci for age-1 silver carp – 66.7-88.9% and age-1 bighead carp – 65.4-77.8%. A significantly higher level of the observed average heterozygosity compared to the expected heterozygosity of age-1 as silver carp (Ho = 75.9%, He = 49,6%), and bighead carp (Ho = 73,6%, He = 47,9%) was observed. This fact indicated on the necessity for performing a stabilization of their genetic structure. The calculated Wright's F index in different age groups showed a predominance of the observed level of the average heterozygosity over the expected one for 22.7–53% in silver carp and 24.5-53.7% in bighead carp. A stabilization of the genetic structure in age-2 silver carp (Ho = 57.8%; He = 47.1%) by the heterogeneity level was observed. Originality. For the first time we analyzed the genetic structure and the level of heterogeneity of the breeding groups of age-1, age-1+, age-2 silver and bighead carps from fish farm Limanske with the use of genetic-biochemical markers. Practical value. The results of the study can be used in selection and breeding works aimed at creating the breeding stocks of silver and bighead carps to control the level of interspecies genetic variability. The obtained experimental data of the genetic structure analysis of silver and bighead carps of different age groups will be used for the monitoring of the genetic structure changes during their adaptation to new environmental conditions.
Proceedings of the 2nd Annual IFOM-IEO Meeting on Cancer. This is a new meeting, it has about 200 attendees from Australia, Austria, Belgium, Brazil, Canada, England, France, Germany, Greece, ...Ireland, Italy, Japan, Netherlands, Spain, Sweden, Switzerland, and the USA. The 2nd IFOM-IEO international meeting on cancer will provide a forum in which the world's leading cancer researchers and young scientists will discuss the latest advances in molecular oncology. The impact of recent breakthroughs in basic research and of emerging technologies on molecular medicine in cancer will be highlighted.
The genome projects have now entered a rapid production phase with complete genome sequences and complete gene catalogues already available for a number of organisms and an increasing number expected ...shortly. In addition the new DNA and protein chip technologies can produce functional data about genes such as gene expression profiles at a rapid rate. There is therefore a large and ever increasing amount of data about genes and molecules. However there is still a huge gap between information at the molecular level and information at the level of integrated biological systems. It is this gap that is addressed in Post-genome Informatics. Post-genome informatics is the analysis of biological functions in terms of the network of interacting molecules and genes with the aim of understanding how a biological system is organized from its individual building blocks. As well as containing a comprehensive survey of the database and computational technologies relevant to molecular sequence analysis, Post-genome Informatics will provide the reader with a conceptual framework and practical methods for the representation and computation of molecular networks.
Originally published in 2005, Information Theory, Evolution and the Origin of Life presents an introduction to the use of information theory and coding theory in molecular biology. The genetical ...information system, because it is linear and digital, resembles the algorithmic language of computers. George Gamow pointed out that the application of Shannon's information theory breaks genetics and molecular biology out of the descriptive mode into the quantitative mode and Dr Yockey develops this theme, discussing how information theory and coding theory can be applied to molecular biology. He discusses how these tools for measuring the information in the sequences of the genome and the proteome are essential for our complete understanding of the nature and origin of life. The author writes for the computer competent reader who is interested in evolution and the origins of life.
Today, biologists all over the world speak the same scientific language of molecular biology and use the same molecular tools. More interest and attention is given to molecular biology of abiotic ...stress tolerance and modes of installing better tolerant mechanisms in crop plants. These studies make plants capable of sustaining their yields even under stress conditions. Further, the information gained may form the basis for its application in biotechnology and bioinformatics. This book does not only review the current status in the physiology and molecular biology of stress tolerance and its improvement in plants but will also trigger further research on this exciting topic.
This manual describes laboratory methodology for diagnosing inborn errors of metabolism. Each chapter is sufficiently detailed so as to be self-contained, thus enabling any individual to adopt the ...method in their own laboratory and obviating the need for additional methods of references. The book is unique in that it is the first of its kind to be published in the last 15 years, and individual chapters have been developed by experts in the field citing both established and 'cutting-edge' technology. Thus, it is sufficiently up-to-date to be applicable to the field of inborn errors of metabolism for all readers and those interested in laboratory diagnosis.
This fully revised translation of the world-renowned German edition covers the complete and modern knowledge of plant biochemistry. The book presents the topic in a concise and simplified manner so ...that students can digest the message and gain a basic knowledge of the entire field of plant biochemistry, from photosynthesis (the synthesis of natural plant products) to all kinds of genetic engineering with its many commercial applications. Topics include cell structure and function, lipid and polysaccharide metabolism, nitrogen fixation, phloem transport, synthesis and function of isoprenoids, phenylpropanoids and other secondary metabolites, plant growth regulation and development. Heldt provides a comprehensive description of photosynthesis, primary and secondary metabolism, the function of phytohormones and molecular engineering. The text covers research findings until the end of 2003 and identifies areas of future research. There are extensive references to the most recent scientific literature.
