Abstract
Innovation in agriculture has been essential in improving productivity of crops and forages to support a growing population, improving living standards while contributing toward maintaining environment integrity, human health, and wellbeing through provision of more nutritious, varied, and abundant food sources. A crucial part of that innovation has involved a range of techniques for both expanding and exploiting the genetic potential of plants. However, some techniques used for generating new variation for plant breeders to exploit are deemed higher risk than others despite end products of both processes at times being for all intents and purposes identical for the benefits they provide. As a result, public concerns often triggered by poor communication from innovators, resulting in mistrust and suspicion has, in turn, caused the development of a range of regulatory systems. The logic and motivations for modes of regulation used are reviewed and how the benefits from use of these technologies can be delivered more efficiently and effectively is discussed.

Abstract
Climate change has posed a challenge for food security all over the world in the form of fluctuating crop yields and novel disease outbreaks in plants. Human society's overdependence on a few food crops does not seem a wise precedence. There are numerous underutilized/orphan/neglected legumes growing in the Indian desert regions that can come to the rescue and act as balanced and sustainable sources of nutrients and health-benefitting nutraceuticals. However, challenges such as low plant yield, unidentified metabolic pathways and off-flavor in the food products derived from them prevent the realization of their full potential. Conventional breeding techniques are too slow to achieve the desired modifications and cater to the sharply rising demand for functional foods. The novel gene editing tools like CRISPR-Cas provide more precise tool to manipulate the target genes with or without introduction of foreign DNA and therefore, have better chances to be accepted by governments and societies. The current article reports some of the relevant 'gene editing' success stories with respect to nutraceutical and flavor profiles in the popular legumes. It highlights gaps and future potential, along with areas requiring caution, in underutilized edible legumes of the Indian (semi) arid regions like Prosopis cineraria, Acacia senegal and Cyamopsis tetragonoloba.

Abstract
BACKGROUND Genetic engineering has stimulated interest in a range of fields, including agribusiness, food technology, food product development, and nutrition. Even though the public opinion on genetically modified (GM) goods is polarizing, the majority of experts believe that the advantages outweigh any potential risks, if at all there are any. As a result, the role of science education is to prepare students to be citizens who have a fundamental understanding of genetic engineering. As the students of life sciences are the future scientific experts and scholars who progress in the subject of genetically modified organisms (GMOs), they need to have correct knowledge of GMOs, GM foods, and appropriate attitudes regarding the same. METHODOLOGY To investigate the knowledge and attitudes of life-sciences university students (n= 203) concerning GM foods, a cross-sectional observational survey-based study was carried out by administering a structured questionnaire across three disciplines of life sciences - Biotechnology, Food Technology, and Nutrition for undergraduates, postgraduates, and post-graduate diploma students. The scores for knowledge and attitudes were divided into tertiles as high, moderate, and low scores. RESULTS 88.2% of the participants agreed to have read about GMOs in their curriculum and 76.8% had defined GM foods correctly. When the participants were categorized into tertiles, it was observed that out of all the high scorers, 45.5% were food technology majors and 43% were biotechnology majors and only 11.3% were nutrition majors. 63.1% of students were found to be in favor of GMOs and GM foods and had a positive attitude toward them. There was a moderately positive association of knowledge levels with attitudes toward GMOs and GM foods (p< 0.05). CONCLUSION Although in general, the life-sciences students had the basic knowledge of GMOs and GM foods, the food technology, and biotechnology majors had better knowledge about GMOs and GM foods as compared to nutrition majors. The attitude scores were directly proportional to knowledge scores which emphasizes the need for robust science education on comprehending the topic better. Incorporating a GM-related curriculum for nutrition discipline can help students learn better about the issues surrounding transgenic technology, food safety, and nutrition.

Abstract
Recently, there has been a remarkable increase in rice production owing to genetic improvement and increase in application of synthetic fertilizers. For sustainable agriculture, there is dire need to maintain a balance between profitability and input cost. To meet the steady growing demands of the farming community, researchers are utilizing all available resources to identify nutrient use efficient germplasm, but with very little success. Therefore, it is essential to understand the underlying genetic mechanism controlling nutrients efficiency, with the nitrogen use efficiency (NUE) being the most important trait. Information regarding genetic factors controlling nitrogen (N) transporters, assimilators, and remobilizers can help to identify candidate germplasms via high-throughput technologies. Large-scale field trials have provided morphological, physiological, and biochemical trait data for the detection of genomic regions controlling NUE. The functional aspects of these attributes are time-consuming, costly, labor-intensive, and less accurate. Therefore, the application of novel plant breeding techniques (NPBTs) with context to genome engineering has opened new avenues of research for crop improvement programs. Most recently, genome editing technologies (GETs) have undergone enormous development with various versions from Cas9, Cpf1, base, and prime editing. These GETs have been vigorously adapted in plant sciences for novel trait development to insure food quantity and quality. Base editing has been successfully applied to improve NUE in rice, demonstrating the potential of GETs to develop germplasms with improved resource use efficiency. NPBTs continue to face regulatory setbacks in some countries due to genome editing being categorized in the same category as genetically modified (GM) crops. Therefore, it is essential to involve all stakeholders in a detailed discussion on NPBTs and to formulate uniform policies tackling biosafety, social, ethical, and environmental concerns. In the current review, we have discussed the genetic mechanism of NUE and NPBTs for crop improvement programs with proof of concepts, transgenic and GET application for the development of NUE germplasms, and regulatory aspects of genome edited crops with future directions considering NUE.

Abstract
A world with zero hunger is possible only through a sustainable increase in food production and distribution and the elimination of poverty. Scientific, logistical, and humanitarian approaches must be employed simultaneously to ensure food security, starting with farmers and breeders and extending to policy makers and governments. The current agricultural production system is facing the challenge of sustainably increasing grain quality and yield and enhancing resistance to biotic and abiotic stress under the intensifying pressure of climate change. Under present circumstances, conventional breeding techniques are not sufficient. Innovation in plant breeding is critical in managing agricultural challenges and achieving sustainable crop production. Novel plant breeding techniques, involving a series of developments from genome editing techniques to speed breeding and the integration of omics technology, offer relevant, versatile, cost-effective, and less time-consuming ways of achieving precision in plant breeding. Opportunities to edit agriculturally significant genes now exist as a result of new genome editing techniques. These range from random (physical and chemical mutagens) to non-random meganucleases (MegaN), zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), clustered regularly interspaced short palindromic repeats (CRISPR)/associated protein system 9 (CRISPR/Cas9), the CRISPR system from Prevotella and Francisella1 (Cpf1), base editing (BE), and prime editing (PE). Genome editing techniques that promote crop improvement through hybrid seed production, induced apomixis, and resistance to biotic and abiotic stress are prioritized when selecting for genetic gain in a restricted timeframe. The novel CRISPR-associated protein system 9 variants, namely BE and PE, can generate transgene-free plants with more frequency and are therefore being used for knocking out of genes of interest. We provide a comprehensive review of the evolution of genome editing technologies, especially the application of the third-generation genome editing technologies to achieve various plant breeding objectives within the regulatory regimes adopted by various countries. Future development and the optimization of forward and reverse genetics to achieve food security are evaluated.

Abstract
The adoption of genome editing depends among others, on a clear and navigable regulatory framework that renders consistent decisions. Some countries like the United States decided to deregulate specific transgene-free genome edited products that could be created through traditional breeding and are not considered to be plant pests, while others are still challenged to fit emerging technologies in their regulatory system. Here we poll international experts in plant biotechnology on what approach should nations agree upon to accommodate current and future new breeding technologies and derived products. A key finding is product-based models or dual-product/process systems are viewed as potential appropriate frameworks to regulate outcomes of genome editing. As regulation of novel products of biotechnology is expected to impact research and trade, we test the impact of experts' worldviews on these issues. Results show that region influences worldviews of trade but not of agricultural innovation. In contrast, there was no effect of experts' worldviews on how products of novel biotechnologies should be regulated.
