    Rethinking underutilized cereal crops: pan-omics integration and green system biology
    (Springer Science and Business Media Deutschland GmbH, 2023-09-30T00:00:00) Rahim, Mohammed Saba; Sharma, Vinita; Pragati Yadav; Parveen, Afsana; Kumar, Adarsh; Roy, Joy; Kumar, Vinay
    Main conclusion: Due to harsh lifestyle changes, in the present era, nutritional security is needed along with food security so it is necessary to include underutilized cereal crops (UCCs) in our daily diet to counteract the rising danger of human metabolic illness. We can attain both the goal of zero hunger and nutritional security by developing improved UCCs using advanced pan-omics (genomics, transcriptomics, proteomics, metabolomics, nutrigenomics, phenomics and ionomics) practices. Abstract: Plant sciences research progressed profoundly since the last few decades with the introduction of advanced technologies and approaches, addressing issues of food demand of the growing population, nutritional security challenges and climate change. However, throughout the expansion and popularization of commonly consumed major cereal crops such as wheat and rice, other cereal crops such as millet, rye, sorghum, and others were impeded, despite their potential medicinal and nutraceutical qualities. Undoubtedly neglected underutilized cereal crops (UCCs) also have the capability to withstand diverse climate change. To relieve the burden of major crops, it is necessary to introduce the new crops in our diet in the way of UCCs. Introgression of agronomically and nutritionally important traits by pan-omics approaches in UCCs could be a defining moment for the population�s well-being on the globe. This review discusses the importance of underutilized cereal crops, as well as the application of contemporary omics techniques and advanced bioinformatics tools that could open up new avenues for future study and be valuable assets in the development and usage of UCCs in the perspective of green system biology. The increased and improved use of UCCs is dependent on number of factors that necessitate a concerted research effort in agricultural sciences. The emergence of functional genomics with molecular genetics might gear toward the reawakening of interest in underutilized cereals crops. The need of this era is to focus on potential UCCs in advanced agriculture and breeding programmes. Hence, targeting the UCCs, might provide a bright future for better health and scientific rationale for its use. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

    Biotechnological attributes of biostimulants for relieving metal toxicity
    (Elsevier, 2023-08-04T00:00:00) Rana, Varnika; Kumar, Adarsh; Singh, Reetu; Kumar, Vinay
    A global scourge, heavy metals (HMs) toxicity with high concentration causes reactive oxygen species (ROS) to attack key biological molecules and has emerged in the past few years, posing a serious threat to human lives and ecosystems and agriculture. In plants, HMs alter the genome and genetic structure and eventually affect their protein and enzyme activities which further impede cellular metabolism. Therefore the growing body of scientific research is emphasizing green synthesis, that is, biostimulants use as the nexus of biotechnology and fertilizer that can be viewed as novel, efficient, eco-friendly, and cost-effective tools to safeguard the detrimental effects on ecosystems. In this regard, this chapter aims to scrutinize the role of various biostimulants against abiotic stresses using various biostimulants including seaweed extracts, protein hydrolysates, humic acids, and fulvic acids. The microbial-based stimulants are also discussed in this chapter. A list of biological processes has also been highlighted as prime targets for removing heavy metal(loid)s toxicity using biotechnological interventions. The biostimulants enhance growth and improve stress tolerance ability in plants. A table of targeted biotechnological attributes is also provided. Recently, a steep rise in interest in biostimulants is driving the development of sustainable green economics and agricultural concepts, while increasing demand for new products and understanding their mechanism of action is increasing. Further, the increasing demand for innovative biostimulants products and an interest in understanding their mechanisms of action will drive HM-free green economics and agricultural sustainability in the coming days. � 2023 Elsevier Inc.

    Genetically modified crop regulations: scope and opportunity using the CRISPR-Cas9 genome editing approach
    (Springer Science and Business Media B.V., 2021-06-10T00:00:00) Gupta, Shweta; Kumar, Adarsh; Patel, Rupali; Kumar, Vinay
    Global demand for food is increasing day by day due to an increase in population and shrinkage of the arable land area. To meet this increasing demand, there is a need to develop high-yielding varieties that are nutritionally enriched and tolerant against environmental stresses. Various techniques are developed for improving crop quality such as mutagenesis, intergeneric crosses, and translocation breeding. Later, with the development of genetic engineering, genetically modified crops came up with the transgene insertion approach which helps to withstand adverse conditions. The process or product-focused approaches are used for regulating genetically modified crops with their risk analysis on the environment and public health. However, recent advances in gene-editing technologies have led to a new era of plant breeding by developing techniques including site-directed nucleases, zinc finger nucleases, and the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR associated protein 9 (Cas9) that involve precise gene editing without the transfer of foreign genes. But these techniques always remain in debate for their regulation status and public acceptance. The European countries and New Zealand, consider the gene-edited plants under the category of genetically modified organism (GMO) regulation while the USA frees the gene-edited plants from such type of regulations. Considering them under the category of GMO makes a long and complicated approval process to use them, which would decrease their immediate commercial value. There is a need to develop strong regulatory approaches for emerging technologies that expedite crop research and attract people to adopt these new varieties without hesitation. � 2021, The Author(s), under exclusive licence to Springer Nature B.V.
