“…With time, the emergence of novel gene-editing tools like CRISPR/Cas9 broke all biological barriers ( Ghosh and Dey, 2022 ; Rasheed et al, 2022a ; Razzaq et al, 2022 ). Increased heat waves threaten food security and damage the soybean crop on large areas ( Ahmad et al, 2021 ; Chennakesavulu et al, 2021 ; Camerlengo et al, 2022 ; Pandita, 2022 ). CRISPR/Ca9 has emerged as a key gene-editing tool for efficient and precise gene-editing of soybean crop; however, little evidence indicates its role in heat tolerance.…”

The soybean is a significant legume crop, providing several vital dietary components. Extreme heat stress negatively affects soybean yield and quality, especially at the germination stage. Continuous change in climatic conditions is threatening the global food supply and food security. Therefore, it is a critical need of time to develop heat-tolerant soybean genotypes. Different molecular techniques have been developed to improve heat stress tolerance in soybean, but until now complete genetic mechanism of soybean is not fully understood. Various molecular methods, like quantitative trait loci (QTL) mapping, genetic engineering, transcription factors (TFs), transcriptome, and clustered regularly interspaced short palindromic repeats (CRISPR), are employed to incorporate heat tolerance in soybean under the extreme conditions of heat stress. These molecular techniques have significantly improved heat stress tolerance in soybean. Besides this, we can also use specific classical breeding approaches and different hormones to reduce the harmful consequences of heat waves on soybean. In future, integrated use of these molecular tools would bring significant results in developing heat tolerance in soybean. In the current review, we have presented a detailed overview of the improvement of heat tolerance in soybean and highlighted future prospective. Further studies are required to investigate different genetic factors governing the heat stress response in soybean. This information would be helpful for future studies focusing on improving heat tolerance in soybean.

“…In recent years, the public awareness and acceptance regarding genome edited food crops have advanced notably since the first GE crop entered the open market in 2021 (Waltz, 2021). Many researchers also highlight the long-term consequences of restricted development, and argue that innovations are required to achieve sustainable food production (Herrero et al, 2021;Camerlengo et al, 2022). It is further suggested that the potato crop in particular would benefit greatly from novel plant breeding methods (Halterman et al, 2016), where the CRISPR-Cas9 is considered one of the most versatile tools for crop improvement (Hofvander et al, 2022).…”

“…Since that time, many applications of this system to agriculture and medicine have been investigated. Several excellent reviews describe the function of the CRISPR-Cas system. , In short, the basic action of CRISPR involves an RNA guide sequence, which locates the targeted portion of DNA, and a protein, such as Cas9, which then makes a break in the DNA at that site. At that point, the endogenous cellular repair mechanism is activated, which is an error-prone process that can result in inactivating the gene.…”

“…CRISPR systems are also being developed to precisely create single-nucleotide variants in targeted DNA or RNA in a process called base editing. While the most frequently described edits to date tend to be single nucleotide or small targeted insertions or deletions, chromosomal rearrangements and epigenetic modifications to enhance or repress gene expression are also possible future applications for genome editing to introduce genetic variation. , …”

Breeding as a means to select improved plant varieties has benefited food security for millennia. Breeders rely on a plant species’ genetic diversity to develop new varieties that will meet the changing agronomic needs of growers, the functional and quality end points required by food processors and a multitude of end-user demands on sensory characteristics, convenience, and price. The history of safe use of crops for food and feed, combined with breeding practices designed to eliminate plants that do not meet performance or safety standards, has successfully enabled introduction of new varieties on a continuous basis. In the United States, the Food and Drug Administration (FDA) has primary oversight of the safety of all plant-based foods including those from new plant varieties. In response to the use of recombinant DNA techniques to introduce modification in plants not possible through traditional breeding, FDA issued a policy statement in 1992 that outlines key considerations for safety evaluation of foods derived from new plant varieties. This includes the history of safe use of the crop and the donor organism from which any new genetic or protein sequences are derived and safety assessment of any newly introduced proteins or changes to the levels of key nutrients or toxins. As understanding of plant genetics has deepened, new breeding tools have become available. Genome editing is one of the latest classes of these new breeding tools that allows plant breeders to target gene loci to create deletions that inactivate gene(s), make modifications that enhance the function of a particular gene or move genes within a gene pool, harnessing existing genetic diversity from within a plant species and its sexually compatible relatives. FDA’s authority and specific guidance continues to be relevant for safety assessment of foods derived from these new plant varieties.
