What may be the reason for less cereal production in the farmer’s field?
Because of repeated use of the soil nutrients needed by the cereal crop by growing the same crop for several seasons, these nutrients decline, thereby crop production. Monocropping also creates the spread of pests and disease, which leads to decline in production.

Why are cereals important to humans?
Over the years, cereals have been the major food consumed by humans and have also been used in animal diet and therefore highly commendable for playing a major role in the preservation of human race. Studies have shown that half of the total percentage of calories consumed in the world is from cereals while it is also the most traded agricultural crop at the international market. This motivates the need to assess its utilisation in the past, present and future. This review shows that much driven by the use of cereals are factors like consumption and dietary pattern of a person or country, technological advancement in adding value to it, income status, market forces of demand and supply, level of affluence and policy. The trend in global cereals utilisation since its domestication has indicated an upward one with bulk of it being consumed as food in developing countries while majority of it goes into feeding livestock in developed countries. Evidence from this study also shows that the per capita utilisation of cereals directly for food is exceedingly great in developing countries than developed countries which is an indicator of malnutrition when not balance with other nutrients as it was observed in Bangladesh where calorie intake of an adult is about 90% from cereals. While there is a steady increase in global cereals utilisation due to its discovered industrial use as fuel, increased population and other factors, it will be expedient to focus on its sustainability and environmental issues that are likely to come up as a limitation to meet future demands.

This chapter introduces the book’s objectives, set to provide a comprehensive overview of healthy cereal and pseudocereal grains, trends in their consumption and (innovative) processing technologies employed not only to increase their digestibility and palatability, but also to increase their nutritional value and safety. It also emphasizes the challenges in conventional processing methods and how innovative processing can be integrated in the cereal/pseudocereal processing chain to provide an efficient value addition to cereals/pseudocereals and products thereof, in line with evolving consumer expectations.
Why is nitrogen important for agriculture?
As a result, the addition of nitrogen fertilizer is necessary to sustain productivity and yields , especially for cereal crops, the planet’s major calorie suppliers. Given the unsustainability of industrial fertilizer production and application, engineering biological nitrogen fixation directly at the roots of plants has been a grand challenge for biotechnology. Here we design and test a potentially broadly applicable metabolic engineering strategy for the overproduction of ammonia in the diazotrophic symbiont Azospirillum brasilense . Our approach is based on an engineered unidirectional adenylyltransferase (uAT) that post-translationally modifies, and deactivates glutamine synthase, a key regulator of nitrogen metabolism in the cell. We show that this circuit can be controlled inducibly and we leverage the inherent self-contained nature of our post-translational approach to demonstrate that multicopy redundancy can improve strain evolutionary stability. uAT-engineered Azospirillum is capable of producing ammonia at rates of up to 500 μM h ⁻¹ OD 600 ⁻¹ . When grown in co-culture with the model monocot Setaria viridis , we demonstrate that these strains increases the biomass and chlorophyll content of plants up to 54% and 71% respectively relative to WT. Furthermore, we rigorously demonstrate direct transfer of atmospheric nitrogen to extracellular ammonia and then plant biomass using isotopic labeling: after 14 days of co-cultivation with engineered uAT strains, 9% of chlorophyll nitrogen in Setaria seedlings is derived from diazotrophically fixed dinitrogen, whereas no nitrogen is incorporated in plants co-cultivated with WT controls. This rational design for tunable ammonia overproduction is modular and flexible, and we envision could be deployable in a consortium of nitrogen fixing symbiotic diazotrophs for plant fertilization. Importance Statement Nitrogen is the most limiting nutrient in modern agriculture. Free living diazotrophs, such as Azospirillum , are common colonizers of cereal grasses and have the ability to fix nitrogen but natively do not release excess ammonia. Here we use a rational engineering approach to generate ammonia excreting strains of Azospirillum . Our design features post-translational control of highly conserved central metabolism, enabling tunability and flexibility of circuit placement. We show that our strains promote the growth and health of the model grass S. viridis and rigorously demonstrate in comparison to WT controls that our engineered strains can transfer nitrogen from ¹⁵ N 2 gas to plant biomass. Unlike previously reported ammonia producing mutants, our rationally designed approach easily lends itself to further engineering opportunities and has the potential to be broadly deployable.
Why is millet flour important?
These are extremely nutritious and are proven to play a pivotal role in preventing and curing several health issues. However, millet flour has poor shelf life due to its high fat content as well as lipase activity which causes rapid development of rancidity and bitterness. Its keeping quality greatly depends on different pre-treatments applied and storage conditions. Scope and approach In the present review, the effect of various processes/treatments like mechanical processing, thermal treatments, fermentation, germination, addition of preservatives, and some novel techniques like gamma irradiation, microwave processing, infrared heating, high-pressure processing, pulsed light processing, and ultrasound processing on storage stability and other nutritional properties of different millet flour was reviewed. Their principle of action, advantages, and disadvantages have also been highlighted. Key findings and conclusions All the technologies emphasized in this review have proven to augment the shelf life of millet flour. However, traditional processes are accompanied by changes in nutritional and functional properties, which necessitate the need for alternatives. Novel thermal and non-thermal techniques were found to cause both microbial decontamination and enzyme inactivation, although their application is limited as far as millet flour is concerned. These techniques are yet to be explored as millets are regaining popularity and have become part of the staple diet of many health-conscious consumers.
How important is maize?
The importance of maize (Zea mays L.) to global agriculture, world economy, and food security is widely known and increasing. Current maize breeding programs are deeply integrated with recent and rapid technological advances in genome sequencing, computational biology, and new genotyping and phenotyping technologies. Transformation and genome editing capabilities are a central hub to an array of advanced molecular and breeding approaches to crop improvement. Tissue culture and somatic embryogenesis play essential and central roles in maize transformation biology. Synergistic applications of maize transformation, advanced genomics, and genome editing provide a potent interdependent triad for functional genomics research and advanced molecular breeding. Implementation of advanced capabilities to transform maize and conduct genome editing will profoundly influence the dynamics of global agriculture ushering in a new era of varietal development and molecular breeding. With over 60.9 Mha planted in 2019 alone, biotech maize accounts for 31% of the world’s maize production. Up to 10% higher yields are achieved using new varieties generated using genetic modification technologies compared to similar conventional varieties. By extension, the impact new varietal releases developed through genome editing will likely be more significant. Advances in transformation and genome editing technologies will facilitate an even wider applicability for the development of new varieties with increasingly complex traits. The introduction of biochemical pathways and the use of synthetic biology have become increasingly more attainable. The future is of genotype independent maize transformation and genome editing, as the working platform will impact world agriculture, global food security, and plant science well into the future.
