A few months back when Sharad Deshpande was talking about some processing tomatoes, I said that there is a lot of history behind processing tomatoes. He said then why don’t you speak on the subject and I said why not. So that is how this talk happened. First, I thought I will speak on breeding tomatoes as its history is even more interesting than what has happened later. I had heard a story when I went to USA for the first time in 1982. I was with Dr Charlie Rick, the father of tomato genetics, in his lab in USDA, UC, Davis, California. He talked about how the processing industry happened, who bred the types suitable for processing, how 80 percent of processing tomatoes of the USA came from California, where we are today and what could be done in this area.

4a. Intestinal Disorders
 
History of health claims
 
According to Bottazzi (1983) it was in 76 BC that the Roman historian Plinius recommended the use of fermented milk for treating gastroenteritis. Metchnikoff claimed that the intake of fermented milk containing Lactobacilli reduces the toxin producing bacteria, thereby increasing the longetivity of the host (Metchnikoff, 1908). Tissier (1905) showed that there was an increase in the Bifidobacteria in breast fed-infants, thus claiming that the administration of Bifidobacteria to infants suffering from diarrhea was very beneficial as they supersede the putrefactive bacteria that causes the disease. Intestinal beneficial microfloras are responsible to resist the disease (Bohnhoff et al., 1954).

3.1. INTRODUCTION 

Transitory waterlogging occurs extensively in both irrigated and dry land agriculture on clay flats and duplex soils. Most of the humid tropical lowlands, with adequate, rain-fed but poor drainage, have the problems of waterlogging, which is further intensified by low water table and poor root aeration. In submerged condition, only root is exposed to excess water and the injury to the shoot is not a primary effect.

The term ‘waterlogging’ is defined as a condition of the soil where excess water inhibits gas exchange of roots with the atmosphere. Waterlogging is different from ‘flooding’ because the latter results in addition factors of partial or complete submergence of the shoot. The waterlogging replaces a gaseous air by liquid water, leading to the gas stresses. Schematic representation of adverse effects of waterlogging on plant growth and survival has been given in Fig. 3.1.

A. Diseases

1. Anthracnose

Hemp anthracnose is caused by two different fungi, viz., Colletotrichum coccodes (=C. atramentarium) and Colletotrichum dematium (Saccardo, 1882; Cavara, 1889).

i) Anthracnose (Colletotrichum coccodes)

Occurrence & severity status

The anthracnose disease occurs on many plants, including hemp (Cannabis sativa). The disease causing fungus is well-studied and it is an important pathogen responsible for black dot disease on potato. The fungus is an unspecialized pathogen, infecting a wide range of host families. It is most common in Canada and commonly regarded as a minor pathogen or secondary invader, but the fungus may seriously affect yield where intensive cropping without rotation occurs. It primarily affects the growth rate of plants and diminishes harvest. Moreover, it becomes fatal occasionally. Hoffman (1958, 1959) reported heavy hemp losses in central Europe. Conversely, Gitman (1968b) considered the pathogen was of little importance in the USSR.

3.1  Write True/False

Q.1    The estimates obtained though various methods of point estimation, in general, do not concide with the true values of the parameters.
Q.2    The statistician is interested in finding an ‘interval’ within which the true value of the parameter θ is expected to lie with certain ‘confidence coefficient’, say (1 – α).

8.1. INTRODUCTION

Aluminium (Al) is not considered as essential nutrient, but at low concentrations it may increase plant growth or induce other desirable effects (Bollard and Butler, 1966; Foy, 1988; Huang et al., 1992a, b; Roy and Mandal, 2005). Al affects about 40-70% of the world arable land, which has the potential for food crops biomass production (Haug and Caldwell, 1985). Acid soils constitute about 3.95 billion hectares globally. About 38% of those are present in Tropical Asia (Datta, 2002). It is believed to cover more than 800 million hectares of forest and tropical Savana ecosystems of tropical America (Jaffe and Rojar, 1994; Prakash 2000). Nearly 75% of Amazon Basin contains acid and infertile soil classified as oxisols and utisols. About 383 million hectares (79%) of the Amazon area, suffers from Al toxicity. Acid soil occurs extensively in the some of the Mediterranean countries and Southern Australia. Low laying acid sulfate of Bay Islands in India chronically suffer from Al-toxicity (Chowdhury et al., 2001).

Abstract: Carnation, is one of the commercial flower crops of the world. There are many forms of carnations, which are excellent for cut flowers, bedding pots, edging and rock gardens. The history of crop improvement and development is highlighted. Their continued popularity has warranted extensive breeding and development of novel phenotypes particularly standards (Sims), sprays, midis, annual, picotees, perpetual, chabaud, malmaison, multiflora, microcarnations, etc. Continuous breeding and improvement of carnation focus on floral fragrance, floral doubleness, dwarf stature, high growth rate, floral colour, reduced calyx splitting, floral longevity and disease resistance. Ample genetic information and trait heritability has been established for this crop. Molecular genetics techniques are valuable tools aiding modern carnation breeders. Numerous genes have been identified and being used to create transformants. Wonderful results achieved through interspecific hybridization, mutation and polyploid breeding are discussed. Poor pollen production, inbreeding depression, linkage between traits, limited gene pool, inadequate seed production, reproductive barriers often pose significant challenges to breeders. Crop ideotypes prescribe numerous traits for incorporation by flower breeders and geneticists, including straight stem, symmetrical flower shape/ form, early/ uniform flowering with high productivity, enhanced shelf life and resistance to physiological disorders and various diseases.

14.1 Model Organism: A model organism is a species that has been widely studied, usually because it is easy to maintain and breed in a laboratory setting and has particular experimental advantages. Model organisms are non-human species that are used in the laboratory to help scientists understand biological processes. They are usually organisms that are easy to maintain and breed in a laboratory setting. For example, they may have particularly robust embryos that are easily studied and manipulated in the lab, this is useful for scientists studying development. They may occupy a pivotal position in the evolutionary tree, this is useful for scientists studying evolution.

Abstract: Pelargonium (syn. Geranium), has become mainstay in temperate landscapes because of its ease of production and cultivation, long lasting bloom, range of plant habits and diversity of uses (perfumery, cosmetic, pharmaceutical and food industries). Confusion exists about nomenclature and taxonomic revision has attempted. Pelargoniums are popular seed and vegetatively propagated bedding and pot plants with numerous phenotypes (Fish type, Ivy leaved, Regal, Angels, Fancy leaves, Scented, Oak leaf) and cultivars (Double/ Bar/ Centre/ Ring/ Vein/ Picotee pattern/ Tulip/ Carnation/ Phlox/ Birds egg flowered) available on the world market. Their continued popularity has warranted extensive breeding and development of novel phenotypes particularly trailing growth habit, reduced plant size, compact form, manipulation of flowers (size, number, coloration, longevity, timing) and disease resistant cultivars. Increasing knowledge of the inheritance of traits, molecular genetic techniques and biotechnological applications are valuable tools aiding modern pelargonium breeders. The need of new cultivars remains strong as divergence among pelargonium market types increases, production system becomes more specialized and new market develops.

Constantly emerging and reemerging vaccine-preventable infectious diseases recently around the globe challenged the health infrastructure and has been a critical concern for the medical fraternity. There are 21 other neglected tropical diseases, as classified and recently updated by the World Health Organisation, many of which are seemingly vaccine-preventable. The unprecedented scenario that the world encountered during the recent COVID-19 pandemic was also a ‘silver lining in the dark cloud’ for primarily the vaccinologists. The scientific world witnessed stupendous developments in vaccine development. One such instance was the cutting-edge mRNA vaccine development platform. Once a vaccine is successfully designed, the next step is scaling it up in a milieu that is conducive for its mass production. There are numerous ways to achieve it, from biological system (animal models like the chick embryo, mouse cell-lines, suspension-cultured tobacco cells) to the non-biological (bioreactor) settings. This chapter provides a comprehensive overview of the intricacies in vaccine development, from designing to large-scale manufacturing (mass production). It delves into key scientific guiding principles behind developing and formulating vaccines, adopting both the traditional and emerging bioprocessing and bioseparation engineering and technology. It also explores the technical and management challenges faced before and during scaling up, including maintaining product efficacy, ensuring high quality for human administration, and navigating regulatory landscapes, among others. The chapter offers a holistic understanding of bioprocessing continuum, to educate and inform the research (academia) and development (bioindustry) community for more promising and effective strategies in the future to optimise vaccine production, thus contributing to the global public healthcare initiatives.

Vegetables are the largest important constituent of our daily diet as well as high value cash crops for small, marginal and large scale growers. These are rich in proteins, vitamins, minerals and dietary fibre which are essential for our normal body functions, prevention of malnutrition and deficiency diseases. Vegetables also play key role in neutralizing the acids produced during digestion of fatty foods and also provide valuable roughages which help in movement of food in intestine. Some of the vegetables are good sources of carbohydrates (leguminous vegetables, sweet potato, potato, onion, garlic and fenugreek) proteins (peas, beans, leafy vegetables and garlic) vitamin A (carrot, tomato, drumstick, leafy vegetables), Vitamin B (peas, garlic and tomato), vitamin C (green chillies, drumstick leaves, cole crops, leafy vegetables and leaves of radish) and minerals (leafy vegetables, drumstick pods etc.). As per dietician recommendation, our daily requirement is 75-125g of green leafy vegetables, 85g of other vegetables and 85 g of roots and tubers with other food (http://AgriInfo.in).

Soil is a loose surface material that provides water, nutrients, and structural support to agricultural plants. It is made up of 45% minerals, 5% organic components, 25% air, and 25% water. Our soils are said to be the source of 95% of the food we eat, either directly or indirectly.

The basis of the food chain is healthy soil. Our soils are the foundation of agriculture and the growing media for almost all plants that provide food. Good crops come from good soils, and healthy crops feed people and other animals. Food quantity and quality are, in fact, closely related to soil quality.

A healthy soil is a dynamic, living ecosystem. It is packed with both microscopic and larger organisms that carry out a multitude of essential tasks, such as nutrient cycling—the process of turning dead and decaying matter and minerals into plant nutrients controlling plant diseases and insect and weed pests, enhancing soil structure, which has a positive impact on the soil's ability to hold water and nutrients, and ultimately increasing crop productivity. Because healthy soil retains or increases its carbon content, it also helps to mitigate climate change.

1. Guidelines on Analytical Terminology

    1.    Accuracy : The closeness of agreement between a test result or measurement result and a reference value.

    2.    Analyte : The chemical substance sought or determined in a sample. This definition does not apply to molecular biological analytical methods.

    3.    Applicability : The analytes, matrices, and concentrations for which a method of analysis may be used satisfactorily.

    4.    Bias : The difference between the expectation of the test result or measurement result and the true value. In practice conventional quantity value can be substituted for true value.

    5.    The bias of a measuring instrument is normally estimated by averaging the error of indication over the appropriate number of repeated measurements. The error of indication is the: “indication of a measuring instrument minus a true value of the corresponding input quantity”.

    6.    Calibration : Operation that, under specified conditions, in a first step, establishes a relation between the values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties and in a second step uses this information to establish a relation for obtaining a measurement result from an indication.

    7.    Certified reference material (CRM) : Reference material accompanied by documentation issued by an authoritative body and providing one or more specified property values with associated uncertainties and traceability, using valid procedures.

The family Solanaceae consists of 85 genera, which include both tuberiferous and non-tuberiferous ones. Brinjal (Solanum sp.), chilli (Capsicum sp.) and tomato (Lycopersicon sp.) are the major fruit vegetables under the family. In all genera, fruit is an indehiscent berry.

A key for the identification of the above three genera are furnished below:

A. Anthers connivant in a cone, longer than filaments

B. Anthers dehisce by apical pores or short slits, leaves entire, lobed or pinnatifid - Solanum

BB. Anthers dehisce introsely by longitudinal slits, the tips empty, leaves pinnatiset - Lycopersicon

AA. Anthers not connivant in a cone, not larger than the filaments, dehisce by lateral slits - Capsicum
