Identification of mutated and abnormal genes is an important goal in genetic counseling and clinical research. Identification and measurement of specific proteins in biological sample is quite laborious and complex. Blotting techniques are gaining importance for identification of unique nucleic acid and protein sequences. Their role is increasing in clinical research and molecular biology.
Selective breeding and artificial selection find history some 10,000 years ago in Southwest Asia, and since then, genetic modifications through plant breeding techniques has emerged as a fascinating field to improve the crop and agriculture however, the plant breeding techniques could not evolve well enough to meet growing food demands for escalating human population. In modern times, agricultural biotechnology is offering tremendous scope and potential to provide food security through crop improvement techniques and protocols following principles of genetic engineering. Modern genetic engineering techniques have promised improved shelf life, better agronomic vigor, and pest-free traits to the field crops, and through these interventions, desirable traits have been induced in the crops. In this chapter, a comprehensive account on the use of genetic engineering in agriculture sciences has been presented.
The relationship of man with plants is since time immemorial and plants provide all fundamental necessities of life. The plants particularly horticulturally grown plants are of high worth because these are screened and man-selected plants to meet their pivotal needs. The horticultural plants are cultivated for coping the needs or for earning livelihood by selling these in local or international markets. Horticulture crops many needs of life and also revenue of life. But due to traditional methods, the yield and productivity has been reduced to low or minimum form. The current era is time of genetic engineering which is technique to induct the desired character in the plant of interest with inserting gene of action through latest biotechnological techniques. The application of genetic engineering and DNA technology has led to the production of novel varieties and cultivars of tomatoes, i.e., "Flavor saver tomato," which are much popular and productive for good yield and similar is trend for other crops.
Plants and their different products obtained through biotechnological approaches are inevitable for life necessities. The advent of different types of varieties, cultivars, or the production of other hormones on a commercial level by applying novel techniques do require the protection of property rights as well as biosafety of procedures keeping humanity secure and safe. Biosafety is the most pivotal; otherwise, if all biotechnological processes are left open may cause loss at the individual level or massive catastrophe due to sudden bio-war through terrorist activities. The safety, security, and proper replication without any accidental or incidental mutation is a prerequisite of the biosafety of biotechnological products. Intellectual property rights (IPRs) and intellectual property protection (IPP) are the next two phases of the safety and security of any biotechnological invention and discoveries. The IPR and IPP provide a fundamental right of protection of novel ideas, neo procedure, products, and then their commercial propagation without any fear of piracy loss and also unnecessary indulging of persons or/and corporates in litigations. So, it is clear 2from the above that patent registration, copyright protection, and licensing of some procedures are always protected and safe under the umbrella of IPR and IPP, complementing the theme and spirit of biosafety of biological techniques all around the globe for betterment and welfare of humanity as general rule and principle. The safe and food security, in conjunction with other life necessities and accessories of life is only secured when all biotechnological and novel ideas, inventions, and products are properly documented and regulated, which is being fulfilled in letter and spirit by biosafety rules, IPR, and IPP promulgated in each country and generally protected by world international protection organization (WIPO) and other sub-bodies of UNO.
Patent is a legal document that provides an authority to the inventor/claim holder who could be a design developer, process builder or a new machine manufacturer. It prohibits others for its misuse, selling or making similar types. With the passage of time to protect one's intellectual property rights (IPRs), patents, trademarks, trade secrets, copyrights, etc., are the types of laws and regulations to comprehend smooth and fair use, profit to the respective bodies and surety to execute safely. Like other things and items, some countries, companies, and scientist use to patent living organisms. Patenting of living forms may be considered as unethical because it tangled with the law of nature and is not acceptable by the society at large. But US Supreme court allows that living organisms can be patent. Plants, animals, and microorganisms of different types are permitted to be patentable. Copyrights are the rights awarded to you by creating an original work, e.g., work reproduction, derivative works, copies distribution, publications, photographs, artwork, etc. Several countries develop their own copyrights to protect owner's rights, royalties, and privileges. Similarly, trade mark 160represents new logo or sign to identify or distinct product. Trademarks are usually designated with some symbols, signs, diagrams, new creation by combining many small items and representing these. Another important term is trade secret which implies for those documents, recipes, innovations, or discoveries that need to be kept confidential or disclosed with the consent of the discoverer and rights remain with its owner or with company. Trade secret remains valid for a time till it becomes generally public.
Genetic engineering, also known as gene modification or gene editing, is a field of biotechnology that involves the direct manipulation of an organism's genetic material in order to modify or add traits. This can be done through a variety of techniques, such as the insertion of genetically modified DNA into an organism, or the disruption or suppression of certain genes. Genetic engineering has the potential to revolutionize the way we produce food, create new medicines, and address environmental challenges. However, it is also a controversial field, with many ethical, social, and environmental considerations. One of the key concepts in genetic engineering is the use of genetically modified organisms (GMOs). These are organisms whose genetic material has been modified using genetic engineering techniques. The goal of using GMOs is often to introduce new traits or characteristics into the organism, such as increased resistance to pests or diseases, or enhanced nutritional value. However, there are concerns about the safety of GMOs, both for the environment and for human consumption. Another important concept in genetic engineering is gene editing, which involves the precise modification of an organism's genetic material at the DNA level. Gene editing has the potential to be used for a wide 222range of applications, including the treatment of genetic diseases and the production of new medicines. However, there are also concerns about the potential ethical implications of gene editing, such as the creation of designer babies or the enhancement of human traits. Overall, genetic engineering is a complex and rapidly-evolving field with the potential to significantly impact many aspects of our lives. While it offers many benefits, it also raises important ethical, social, and environmental considerations that need to be carefully considered as the field continues to develop.
Since genetic engineering has been used to develop new recombinant species of plants, animals, and microorganisms, different enzymes are discovered based on their properties, sources, and functions to be used in the recombination process. The field of genetic engineering uses several tools and techniques. These tools include a wide array of enzymes viz. endonucleases (ER), ligases, methylases, polymerases, etc. In this chapter, we tried to summarize some of these enzymes, their types, and their function used in genetic engineering and molecular biology to help in better understanding and utilization of these enzymes.
The successful synthesis of recombinant DNA is followed by its introduction into a host cell. A recombinant DNA outside the host cell is worthless. To be meaningful, it has to transcribe and translate which requires a host cell. The host provides machinery for the replication and expression of recombinant DNA, which allows its cloning and expression respectively. Therefore, scientists introduce recombinant DNA into the host cells to achieve their goals. In this chapter, we would be discussing different methods that are commonly used for introducing recombinant DNA into the host cell.
Food security and quality products are inevitable for life sustenance. The population of human being is exponentially increasing, and this is creating food issues. There is one way to increase the cultivation area of agriculture or increase double crops cultivation in a year. For this new crop cultivars have to be produced, and this can be comprehended through using the latest biotechnological techniques. For this genetic engineering technique (GET) is very promising to cope this plethora of food security. The plants or other organisms produced through GET is currently being promulgated and organisms produced using this GET are called genetically modified organisms (GMOs). Albeit these GMOs have mitigated the issue of food scarcity, but it has also many other challenges of side effects with different paradigms. There is an issue to reveal and analyze biodiversity loss, and other health issues of GMOs. There is need to study the endogenous toxins in plants and/or other GMOs. This chapter encompasses the holistic preview of GMOs, their merits, and demerits. GMOs are those which have foreign genes. Genes with desired characteristics are identified and isolated. Then these isolated genes are 90introduced into target organisms with the help of biological vectors. These transgenic organisms having genes of interest from other organisms incorporated into their genome are called GMOs. GMOs are essentially to be analyzed properly prior to use. The key features in context of use of GMOs may exhibit side-effects for health. The use positive use of GMOs is also beneficial to cope the needs of everlasting increment in the human world population. The GMOs are providing very promising scope in human history.
The concept of gene from mere abstract to a more complex and concrete form has been fascinating through ages now. Its precise definition has not been finalized yet by the biologists because of its dynamic characteristics and as such its deciphering continues till date. The chapter provides a glimpse of the chronological events that were taken forward for proper understanding of the concept of what basically gets transmitted from parent to the offspring in the form of gene and what it is made of, keeping in view its universal mechanism of operation which seems to be same for all living organisms with some minor variations.
Recombinant DNA technology was only a theory a century ago when it came to improving desired traits in live organisms by regulating the expression of target genes. However, in more recent times, this domain has proven to have significant effects in advancing human existence. Scientists utilize rDNA technology for a variety of objectives due to its broad range of uses, but there are several hazards involved in doing so. Recombinant technology may negatively impact the environment, human health, and animals, either explicitly or implicitly, based on a study of significant findings. Additionally, the increased use of this technology has raised safety issues including gene pollution of the environment resulting 184in superweeds and antibiotic-resistant microbes. Increased use of genetically modified foods has been linked to a number of health problems in both humans and animals, including toxicity, antinutritional effects, allergenicity, and carcinogenicity. Due to the potential for harm to both the environment and human life, several safety precautions must be taken when utilizing this technology. This chapter describes in great depth a few negative consequences of recombinant DNA technology.
Department of Plant Breeding and Genetics, Bahauddin Zakariya University, Multan, PakistanMolecular markers perform a significant role in marker-assisted breeding (MAB) which is an advanced method of traditional breeding. It assists in the development of unique and new traits in plants within a short time. Moreover, it is used for tagging the distinctive features available at any site in the whole species genome. Many DNA and molecular markers are identified that regulate the change of genome sequence. Currently, QTL mapping increases the concepts relating to polygenes that regulate the vital characters of plants, whereas association mapping helps to provide a framework related to the phylogenetic traits. By the way, molecular 252marker is significantly worked in this study. In this chapter, we sum up the molecular markers for enhancing the information related to their types and applications, in various features of breeding. Numerous markers are illustrated with their protocols and somewhat unique markers that are widely utilized today, such as CAPS, SNP, and dCAPS, etc. For agriculture research, extensive molecular genomic markers are present. These molecular markers are categorized into several groups based on their uses such as RAPD markers assist to find and screen the hybrids depending on drought and salt stress tolerance, although SSR markers are important for the determination of stress resistance. Similarly, these markers have a significant function in the QTL mapping of stress concerning genes. Saltol for salt stress is basic Gene that work under these stresses. Moreover, the SNP markers help in the mapping of genes and the sequencing of stress-associated characteristics in parent genotypes. DNA markers simplify marker-assisted breeding to increase the resistance in the response to abiotic stress by modern technologies and modifications of markers. In this section, we also describe the procedures used for different kinds of molecular markers that increase the possibility of their applications.
