Application of Genetics in Shrimp Farming

Studies of genetic variation within and among species of penaeid shrimp in nature are of interest to culturists. They provide information about genetic differences among potential founder populations for initiation of aquaculture stocks. In aquaculture, the application of genetic techniques provides opportunities to maximize the benefits of selective breeding, develop new strains of species, including hybrids, maintain genetic vigor in farmed stocks and provide an early warning system for possible undesired inbreeding, explore the potential of genetically enhanced traits such as improved growth rates and disease resistance.

Bioconjugates Derived From Silver Nanoparticles

The starch capped Ag nanoparticles were obtained by the chemical reduction of AgNO3 and they were characterized by the isolation of DNA from E.Coli (pUC18) has resulted in single strand DNA which was subsequently modified with Traut’s reagent. The introduction of thiol group to the DNA by Traut’s reagent facilitates the formation of bioconjugate. The Ag-DNA bioconjugate was characterized by spectroscopic techniques and SEM studies. The comparative study of the scanning electron micrographs of the free DNA and the bioconjugate clearly demonstrated the binding of Ag nanoparticles with DNA through the linker group. The vibrational spectrum of the bioconjugates also provides additional evidence to its formation. The Surface Plasmon Resonance spectrum of the Ag nanoparticles exhibits its absorption maximum at 419nm while its DNA bioconjugate shows its absorption maximum at 437 nm. It has been used as a biosensor.

DNA: The Story of the Genetic Revolution

Along with Francis Crick, James Watson was the discoverer of the double helix structure of the DNA molecule, realising both how it was able to reproduce itself and how, through its immense variety, it was able to pass on genetic instructions from one generation to the next. Their discovery paved the way for fifty years of explosive scientific achievement of extraordinary importance, both in strictly scientific terms and in its technological and social significance.From Dolly the sheep to GM foods to designer babies, science-related newspaper headlines have been dominated by the implications of their work. In DNA, now fully updated and revised to include new findings in gene editing, epigenetics and agricultural chemistry, as well as two entirely new chapters on personal genomics and cancer research, Watson tells the story of this pioneering research and its impact on the world in which we live, from its beginnings to the present day. This is the most comprehensive and authoritative exploration of DNA’s impact – practical, social, and ethical – on our society and our world.

Bacterial Diversity – Exploration Methods

Bacteria account for a major proportion of Earth’s biological diversity. They play essential roles in quite diverse environments and there has been an increasing interest in bacterial biodiversity. Research using novel and efficient tools to identify and characterize bacterial communities has been the key for elucidating biological activities with potential for industrial application. The current approach used for defining bacterial species is based on phenotypic and genomic properties. Traditional and novel DNA-based molecular methods are improving our knowledge of bacterial diversity in nature. PCR-based methods investigating 16S rRNA gene sequences, and other approaches, such as the metagenome, have been used to study the physiology and diversity of bacteria and to identify novel genes with potential pharmaceutical and other biotechnological applications.

Factors Affecting Yield and Milk Composition in Dairy Animals dna fingerprinting of trees and genetic diversity of syzygium cumini Factors Affecting Yield and Milk Composition in Dairy Animals dna fingerprinting of trees and genetic diversity of syzygium cumini

Factors Affecting Yield and Milk Composition in Dairy Animals

Milk is a nutritious, cost-efficient source of protein, minerals and vitamins. Cattle, goats and sheep have been the major sources of milking for human consumption. However, these species’ milk yield and composition is known to be influenced by genetic and non-genetic factors. This is on the background that genetic factors such as the genotype are difficult to control, unless through selective breeding. There are variations in milk yield and composition, not only between, but also within species, because of diversity among genotypes, management practices, stage of lactation, etc., and also interactions among these factors. These environmental and physiological factors (stage of lactation, pregnancy, prolificacy, etc) greatly influence the amount and composition of milk that is actually produced. Some non-genetic factors, such as the nutrition and management of the milking animals can be manipulated by the dairy farmer to improve milk yield and produce high quality milk. This book attempts to explore the influence of genetics and some non-genetic factors on yield and milk composition in cattle, goat and sheep.

Molecular approaches to manage taro leaf blight

Taro leaf blight caused by Phytophthora colocasiae is a major constraint to taro cultivation. To manage taro leaf blight and design breeding programme, it is crucial to recognize the genetic diversity of taro and P. colocasiae. We studied genetic structure of taro and P. colocasiae in India. Biochemical alterations in taro plants infected by the P. colocasiae were studied and changes in peroxidase, ?-1,3-glucanase, L-phenylalanine ammonia-lyase, total phenol and total sugar were evaluated. We employed suppressive subtractive hybridization, high through put DNA sequencing and bioinformatics to identify the defense related genes in taro induced by P. colocasiae infection. Two putative resistance genes and a transcription factor were identified among the upregulated sequences. Our study illustrated that identified genes will be useful to engineer disease protection in taro.

Genetic diversity of Fagus orientalis Lipsky in Iran

Among the broad-leaved temperate forests of the northern hemisphere, Iran’s Hyrcanian forests are very particular. The Hyrcanian forest ecosystem is considered to be one of the last remnants of natural deciduous forest in the world. In this area beech survived intense climate and geological changes during the Quaternary, which occurred despite the fact that this area was not covered by ice and therefore was only indirectly influenced by the glaciations. Hyrcanian commercial forests in Iran were nationalized in 1963. Since then, the area has declined significantly from 3.4 to less than 1.3 million ha in 2002. The two main technical reasons for the failure of this system in these forests are unsuitable harvesting methods during the last 40 years and lack of forest protection. There is an urgent need to improve conservation of this tree species through better forest management, with the aim of both genetic resource conservation and high quality timber production. This book provides basic information on gene conservation and management of beech forests, by studying the genetic diversity within and among populations/regions; and shed light on the history of beech in Iran.

Genetic diversity in turmeric (Curcuma longa L.)

Turmeric (Curcuma longa L.) is one the best known among various taxa of economic, medicinal (anti-cancerous, healing, blood purifier properties), ornamental and cultural importance of the genus Curcuma. India and Thailand with at least 40 species in each area have the highest diversity. Genetic variability in a population can be partitioned into heritable and non-heritable variation with the aid of genetic parameters such as variance, genotypic coefficient of variation, heritability and genetic advance, which serve as a basis for selection of some outstanding genotypes from existing ones. Cluster analysis have proved to be effective methods in grouping turmeric accessions that may facilitate effective utilization of the accession in crop improvement programmes through selection, as conventional breeding is difficult in this crop. Moreover, correlation and path analysis of morphological traits indicated importance of desirable traits for strengthening the turmeric breeding programme for higher rhizome yield.

Morpho-molecular Genetic Diversity in Durum Wheat

This book contains an investigation carried out in twenty-eight durum wheat genotypes to find out the genetic diversity through morphological and molecular markers evaluated under randomized block design with three replications. The observation were recorded on ten quantitative traits viz., days to earhead emergence, grain filling period, days to maturity, plant height (cm), number of effective tillers per plant, spike length (cm), number of spikelets per spike, peduncle length, 1000 grain weight (g) and grain weight per plant (g).Different genetic parameters like genetic diversity, genetic advance, path coefficient analysis etc. were estimated. Twenty-eight genotypes were divided into seven clusters in genetic divergence study using SSR markers. The clustering pattern did not show any relationship between geographic distribution and genetic divergence as genotypes from the same origin scattered in different clusters and the genotypes of different areas were grouped in the same cluster.

Role of Oxidative Stress in Ovarian Cancer Progression dna fingerprinting of trees and genetic diversity of syzygium cumini Role of Oxidative Stress in Ovarian Cancer Progression dna fingerprinting of trees and genetic diversity of syzygium cumini

Role of Oxidative Stress in Ovarian Cancer Progression

Ovarian cancer is the third most common malignancy amongst Pakistani women. It is a silent killer and kills a number of females silently because in most of the cases when this cancer is diagnosed it is on 3rd or 4th stage. Development of this cancer is influenced by genetic, biochemical and environmental factors. Oxidative stress and DNA damage play a pivotal role in its progression. So, the objective of this study was to see the effect of oxidative stress in causation and progression of ovarian cancer and its impact on DNA damage, homocysteine levels and total antioxidant status in ovarian cancerous patients. This study also measured new biomarkers that are closely linked to the progression of ovarian cancer and also found their correlation. The results of study show that excessive inflammation and oxidative stress but low levels of antioxidants cause an increase in DNA damage. There is a direct relationship between oxidative stress and DNA damage. This study suggests the use of antioxidants as drugs to reduce oxidative stress.
