This practical manual is an excellent compilation of techniques for researchers interested in various aspects dealing with cyanobacteria, besides providing basic knowledge on this fascinating group of organisms. Despite the availability of similar compilations, this stands out in terms of its clarity and âsimple to understand and do- languageâ, besides information on the latest advances in the field. Beginning with the basics of isolation, followed by purification and identification, the manual uses simple and effective vocabulary for those working with cyanobacteria, beginners or interested scholars. An important inclusion is the section on microscopy, from light microscropy to electron microscopy, which is a fascinating topic for those interested in understanding the ultrastructural features of these photosynthetic prokaryotes. Axenization and getting clones are one of the difficult aspects of cyanobacteriology and these details are given well, with illustrations. The protocols for lipid and protein extraction are explained in detail, and the use of molecular tools is also dealt suitably. The chapter on preservation of cyanobacteria, an important set of techniques for maintenance and storage, provides useful information not only for researchers, but also for germplasm culture collection curators. Overall, this compilation will provide useful for all researchers, particularly those interested in using cyanobacteria as their workhorses in their research programs.
Attaining food security for a growing population and alleviating poverty while sustaining agricultural systems under the current scenario of depleting natural resources, negative impacts of climatic variability, spiraling cost of inputs and volatile food prices are the major challenges before most of the Asian countries. The Indian agricultural production system faces the daunting task of having to feed 17.5 percent of the global population with only 2.4 per cent of land and 4 per cent of the water resources at its disposal. It is estimated that by 2050, the countryâs food grain requirement will be 377 million tonnes (mt) to feed about 1.7 billion populations as against present production of ~272 mt (2016-17). With the continuously degrading natural resource base compounded further by global warming and associated climate changes âbusiness as usualâ approach will not be able to ensure food and nutrition security to the vast population. The challenge is formidable because more has to be produced with reduced carbon and water footprints. Sustainability of agricultural systems is paramount importance for provisioning of food for perpetuity. The principal indicators of non-sustainability of agricultural systems includes: soil erosion, soil organic matter decline, salinization, acidification etc. These are caused mainly by: (i) intensive tillage induced soil organic matter decline, soil structural degradation, water and wind erosion, reduced water infiltration rates, surface sealing and crusting, soil compaction, (ii) insufficient return of organic material, and (iii) monocropping and imbalanced use of various agricultural inputs. Therefore, a paradigm shift in farming practices through eliminating unsustainable parts of conventional agriculture is crucial for future productivity gains while sustaining the natural resources. Rainfed areas, which constitute about 61% of the gross cultivated area, contribute only 42% to the total food production, while 39% of the irrigated area accounts for 58% of the national food basket. The challenge before the Indian agriculture, is to transform rainfed farming into more sustainable and productive systems through efficient use of natural resources. To achieve this, harnessing the potential of integrated farming systems, integrated nutrient management, and integrated water management needs to be undertaken from conservation point of view through location specific technologies. Conservation agriculture (CA) is a way to cultivate crops, based on no vertical perturbation of soil (zero and conservation tillage), with crop residue management and cover crops, in order to offer a permanent soil cover and a natural increase of organic matter content in surface horizons. CA is based on optimizing yields and profits, to achieve a balance of agricultural, economic and environmental benefits. It advocates that the combined social and economic benefits gained from combining production and protecting the environment, including reduced input and labor costs, are greater than those from production alone. CA is reported to reduce production cost by Rs. 2,000 to 3,000/ha, enhance soil quality, C sequestration and build-up in soil organic matter, enhance water and nutrient use efficiency, reduce greenhouse gas emission and improve environmental sustainability, provide opportunities for crop diversification and intensification and improve resource use efficiency through residue decomposition, soil structural improvement, increased recycling and availability of plant nutrients. The C-sequestration potential of CA is estimated to be 1.8 t CO2/ha/year. By sequestering of 1 tonne carbon in humus, it is possible to conserve 83.3 kg N, 20 kg P and 14.3 kg S/ha. Therefore, management of carbon not only helps in sequestration of carbon but also helps in restoring soil fertility. However, lack of appropriate seeders, competing use of crop residues; burning of crop residues and lack of skilled and scientific manpower and inappropriate extension strategies are the major bottlenecks in popularizing CA in India. The present book on âConservation Agriculture for Advancing Food Security in Changing Climateâ being published in two volumes (Vol.1 & 2) deals with various aspects of CA in relation to efficient use of natural resources, crop diversification, complementary interactions among crop-livestock-tree components, soil and water conservation, rehabilitation of degraded lands, improving soil quality, climate smart farming and socio-economical perspectives. Experts and researchers from different agroclimatic zones of the country contributed chapters to enrich the quality of book. The book is divided into eight sections with each section having multiple chapters to cover the section appropriately.
The knowledge of plant systematics is useful in understanding flora at fundamental taxonomic, structural, functional and metabolic level since it gives a comprehensive and complete information based on biological classification of plants. Each plant is assigned a proper position in the hierarchy of flora, with checkpoints and filters to store useful information and keep some in storage.
Plant improvisation in terms of modifications or introduction of altogether new features can be done using modern biotechnological techniques based on tissue culture, molecular biology, enzymology, fermentation, plant breeding and genetics, microbiology etc. for improved plant growth, better adaptation and survival, crop yield in terms of improved disease and climate change resistance etc., converting plant bioresources into dynamic bioreactors which can become sources of useful metabolites, compounds, drugs, enzymes, vaccines etc. In addition new hybrid varieties with improved features can be developed after focusing upon plant species amenable to genetic manipulation. Large information thus generated can be interpreted through predictive-modeling studies and bio-informatic tools can be utilized for analyzing data generated spatially and temporally over the years.

The term biotechnology was used for the first time by Karl Erkey, a Hungarian Engineer in 1919. Although biotechnology has been an integral part of ancient civilizations as per records, it has evolved into a comprehensive yet elaborate, extensive yet precise and indispensible subject for research being rooted and connected to all basic areas of life sciences in terms of research and analysis.
Biotechnology is based on use of biological agents, systems and mechanisms for generation of useful products and services by application of tools and techniques for overall benefit to mankind. It encompasses the intricacies of all branches of life science amalgamating them with broad research areas of environment, agriculture, pollution, drugs and pharmaceuticals, vaccines, detailed structure of bio-molecules and their functions.
An altogether new era has dawned upon biotechnology, as a result of which it has endowed and empowered us with novel, modified and improved products. These products have become a source of economic upliftment and development, which are also proved to be foundation stones for industries and capital generation. We are living in the age of genomics which has further evolved into proteomics, metabolomics, metagenomics etc. and new branches based on application of software programmes for data research, analysis and interpretation- bioinformatics and biostatistics.
Biotechnology thus offers a plethora of opportunities and avenues to people who wish to pursue their career in biotechnology. Keeping this in view, the present book was planned and designed as a source of crisp, concise and complete information under one roof. We hope that the students preparing for different competitive exams find this book helpful and informative for achieving their goal. A sincere effort has been made to present information in short answer type format and multiple choice question format so as to cover the basics, finer points, critical nuggets of information and contemporary news as well. We hope to further such academic endeavors in future and hope for a good response.
