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.

Purpose of Growing Microgreens in Space Farming

Microgreens are a perfect dietary ingredient in space because of their special benefits, which have been explained in earlier chapters. In an atmosphere of a spaceship with limited water and electrical power for artificial illumination, their comparatively low light and water consumption are advantageous. Furthermore, because spaceships and shelters have limited capacity, microgreens' tiny size might be advantageous. Given the right sanitization procedures, microgreens may be harvested fresh and consumed right away. Their striking colour and robust flavour may also improve meal presentation and pique astronauts' appetites. 

Importance of Light in Microgreens Growth

Microgreens depend heavily on light for their growth and development. Microgreens, being photosynthetic organisms, are very dependent on light for the process of photosynthesis, which produces energy. Sufficient exposure to light is necessary for the production of chlorophyll, for vigorous leaf growth, and for the accumulation of beneficial chemicals such carotenoids and phenolics (Mocanu et al., 2021). Research by Demotes-Mainard et al. (2016) and Kopsell et al. (2005) highlights the direct relationship between microgreens' phytochemical composition and light quality, showing how changes in light spectrum affect it.

Microgreens are tiny seedlings of some wild species as well as edible herbs, cereals, and vegetables. They are developed from the seeds of vegetables, legumes, herbs, and cereals and are regarded as immature greens (requiring light for photosynthesis and growing medium). They are picked shortly after the single set of true leaves has emerged from the cotyledon leaves. According to Xiao et al. (2012), microgreens have 4-6 times the nutritional density of their mature counterparts.

Introduction

Another limitation in a remote area such as the high-altitude region is the steady supply of wholesome and fresh food. Indian troops are stationed up to 2200 feet above sea level; generally speaking, high altitude is defined as elevations between 8000 and 15,000 feet above sea level. When someone who is not acclimated to high altitudes is exposed, they can experience a set of symptoms known as acute mountain sickness (AMS). One of the most severe symptoms of AMS is hypoxia. There may be neurological and cerebral symptoms, such as diminished ability to focus for extended periods, memory problems, problems with hearing and vision, vertigo and tinnitus, and irritability. The low appetite may persist; additional issues linked to high altitude include anorexia with weight loss, sleeplessness, and physical and emotional exhaustion.

The impact of biotic and abiotic constraints, the machinery revolution, faster access to information, city development, social and economic context, climate changes that affect agricultural products and people's movement from one region to another, population income, new cropping technologies adapted to people's demand for food diversification and supply, technical and genetic progress, the impact of biotic and abiotic constraints, the machinery revolution, faster access to information and city development have all had an impact on agricultural market trends over the last ten years. (Bonciu et al., 2020a, Bonciu et al., 2020b).

There is a high demand for arable land to meet food demand and end malnutrition due to the growth of megacities and the global urban population. To enhance yield per unit area, conventional agricultural practises result in agricultural intensification and land clearing for crop cultivation. It has been established that these behaviours have a negative effect on the ecosystem, including soil and water contamination. It is crucial to take into account the application of vertical farming technology which makes use of both horizontal and vertical space and utilises nutrients, water and time (off-season production with artificial illumination) more efficiently to create a larger yield per unit volume of area than conventional outdoor farming. Since microgreens are rich in phytonutrients and are easily harvested, it is being thought of to grow them utilising cutting-edge vertical farming technology. Forest area being turned over to agriculture causes deforestation, the depletion of natural resources like groundwater, loss of biodiversity due to the destruction of habitats, increased soil erosion and greenhouse gas emissions.

There are several difficulties involved with consuming and storing microgreens. Addressing low shelf life and putting into practice efficient postharvest management for microgreens provide formidable challenges for researchers. It's critical to comprehend any relationships that might exist between spoiling and human pathogen contamination. Research has indicated that microgreens including basil, lettuce, parsley, melons, and spinach can have infections from pathogens during the seed-to-harvest stage (Alegbeleye et al., 2018). Growing environments that support the growth or transfer of microorganisms, processing techniques that expose the crop to contaminants from people or animals, and physiological traits of the plant that facilitate contact and binding with microorganisms are some of the factors that contribute to this risk (Maluin et al., 2021). Because external fertilizers and manures are applied sparingly, there is little contamination even though microgreens are protected from pests and insects by controlled surroundings.

Even while the world is ageing, it is not prepared for it. There are 962 million people over 60 in the world as of 2017 with 310.0 million of them living in wealthy countries and 652.2 million in developing ones, according to data from the UN's Department of Economic and Social Affairs (DESA-UN 2017). According to projections, there would be 2.1 billion seniors worldwide by the year 2050 (rich countries: 421.4 million, developing countries: 1670.5 million). By 2030, 80% of the old people in the globe will live in developing countries (DESA-UN, 2015). Elderly individuals in rural developing countries confront challenges such as the lack of pension coverage, work difficulty and high medical costs. Their poor diets and deteriorating poverty raise their risk of chronic illnesses like diabetes, heart disease and cancer (Marshall et al., 2001). 

The main micro and macro nutrients associated with microgreens are Fe, Zn, K, Ca, N, P, S, Mn, Se and others. Microgreens are a fantastic source of biological phytochemicals, which can significantly improve both human health and disease. In addition to these mineral components, the key bioactive compounds including ascorbic acid, phylloquinone, tocopherol, beta-carotene, phenolic antioxidants, carotenoids, anthocyanins, glucosinolates and sugar content are said to be present in higher concentrations in microgreens. The numerous bioactive phytochemicals (Table 2) that are present in the various types of microgreens are covered in more detail in the ensuing subsections:
