“…However, multiplex CRISPR/Cas9-mediated metabolic engineering was performed to increase soybean isoflavone content and resistance to soybean mosaic virus [60]. In addition, researchers from Universidad de la República and Instituto Nacional de Investigación Agropecuaria (INIA) used CRISPR to develop glyphosate-resistant soybean [61,128], while the Brazilian company Tropical Melhoramento & Genética and the Israeli company Evogene collaborated to develop a soybean resistant to a plant nematode that destroys crops and decreases crop yields (https://www.evogene.com/, accessed on 17 November 2021).…”

Climate change and the need to feed an increasing population undermines food production and safety, representing the reasons behind the development of a new agriculture that is much more sustainable, productive and accessible worldwide. Genome editing and, in particular, clustered regularly interspaced palindromic repeats/CRISPR-associated protein (CRISPR/Cas) tools will play a major role in plant breeding to address these concerns. CRISPR/Cas includes a series of genome editing tools relying on the recognition and cleavage of target DNA/RNA sequences to introduce specific mutations.

“…The development of gene-edited herbicide-tolerant yam accessions can effectively alleviate the weed challenge while alleviating crop phytotoxicity due to the reduced need for repeated use of chemical herbicides. Among the potential target gene orthologues in yam include the EPSPS (5-enolpyruvylshikimate-3-phosphate), ACCase (acetyl-coenzyme A carboxylase), ALS (acetolactate synthase) genes ( Dong et al, 2021 ). As Syombua et al (2021) discussed, genome engineering strategies also hold immense potential for improving the yield and nutritional quality of yams.…”

Sustainable intensification of agriculture in Africa is essential for accomplishing food and nutritional security and addressing the rising concerns of climate change. There is an urgent need to close the yield gap in staple crops and enhance food production to feed the growing population. In order to meet the increasing demand for food, more efficient approaches to produce food are needed. All the tools available in the toolbox, including modern biotechnology and traditional, need to be applied for crop improvement. The full potential of new breeding tools such as genome editing needs to be exploited in addition to conventional technologies. Clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas)-based genome editing has rapidly become the most prevalent genetic engineering approach for developing improved crop varieties because of its simplicity, efficiency, specificity, and easy to use. Genome editing improves crop variety by modifying its endogenous genome free of any foreign gene. Hence, genome-edited crops with no foreign gene integration are not regulated as genetically modified organisms (GMOs) in several countries. Researchers are using CRISPR/Cas-based genome editing for improving African staple crops for biotic and abiotic stress resistance and improved nutritional quality. Many products, such as disease-resistant banana, maize resistant to lethal necrosis, and sorghum resistant to the parasitic plant Striga and enhanced quality, are under development for African farmers. There is a need for creating an enabling environment in Africa with science-based regulatory guidelines for the release and adoption of the products developed using CRISPR/Cas9-mediated genome editing. Some progress has been made in this regard. Nigeria and Kenya have recently published the national biosafety guidelines for the regulation of gene editing. This article summarizes recent advances in developments of tools, potential applications of genome editing for improving staple crops, and regulatory policies in Africa.

“…However, a vast improvement has been achieved through CRISPR/Cas9-mediated genome editing-utilizing the same Cas9 enzyme flexibly using different guide RNAs targeting various specific gene targets, allowing genetic material to be added, removed, or altered at particular locations in the genome (Jaganathan et al 2018). Application of these techniques has the potential to result in the development of nontransgenic modified crops with the desired trait (Dong et al 2021;Wang et al 2021). Having a more economical and faster approach opens the possibility of employment of HR crop technologies into minor or smaller area crops, where fewer traditional herbicide options exist today.…”

Western United States and Canada perspective: are herbicide-resistant crops the solution to herbicide-resistant weeds?

Herbicide-resistant (HR) crops are widely grown throughout the United States (U.S.) and Canada. These crop-trait technologies can enhance weed management and therefore can be an important component of integrated weed management (IWM) programs. Concomitantly, evolution of HR weed populations has become ubiquitous in agricultural areas where HR crops are grown. Nevertheless, crop cultivars with new or combined (stacked) HR traits are continuing to be developed and commercialized. This review, based on a symposium held at the Western Society of Weed Science annual meeting in 2021, examines the impact of HR crops on HR weed management in the U.S. Great Plains, U.S. Pacific Northwest, and the Canadian Prairies over the past 25 years, and their past and future contributions to IWM. We also provide an industry perspective on the future of HR crop development and their role in resistance management. Expanded options for HR traits in both major and minor crops are expected. With proper stewardship, HR crops can reduce herbicide-use intensity and help reduce selection pressure on weed populations. However, their proper deployment in cropping systems must be carefully planned by considering a diverse crop rotation sequence with multiple HR and non-HR crops and maximizing crop competition to effectively manage HR weed populations. Based on past experiences in the cultivation of HR crops and associated herbicide use in the western U.S. and Canada, they have been important determinants of both the selection and management of HR weeds.
