“…Multiplexing, or the simultaneous targeting of many genes with a single molecular construct, is one of the added benefits of the CRISPR/Cas9 system. Both individual transcription units and polycistronic forms of multiple sgRNAs can be inserted (Čermák et al, 2017;Rezk et al, 2023;Sattar et al, 2023). Many experiments have been reported in bread wheat using different explants with different transformation methods, such as electroporated microspores (Bhowmik et al, 2018), PEGtransfected protoplasts Zhang et al, 2017), cell suspension Agrobacterium transformation (Upadhyay et al, 2013), immature embryos and immature embryo Agrobacterium transformation (Howells et al, 2018;Singh et al, 2018), immature embryos, immature embryo particle bombardment transformation (Gil-Humanes et al, 2017;Wang et al, 2018;Hamada et al, 2018).…”

Sustainable agriculture is essential to attain food security and address increasing climate change concerns. Population, abiotic and biotic stresses and limited agricultural water supplies and land are important barriers to cereal crops production, in addition to extreme weather. These factors influence their quality and productivity. Therefore, there is a pressing need for effective methods of food production under these conditions. For many individuals in low- and middle-income nations, cereals represent a key food source. Developing cereal crops with enhanced flexibility, high yields, and the ability to tolerate these biotic and abiotic problems is therefore essential. Modern OMICS techniques, next-generation sequencing, bioinformatics tools and the most recent improvements in genome editing tools (GET) have made targeted mutagenesis conceivable. By altering a crop variety's endogenous genome, which is free of any foreign genes, genome editing (GE) enhances the crop variety. Therefore, crops that have undergone GE but have not integrated foreign genes are not considered genetically modified organisms (GMOs) in a number of countries. GE is being used by researchers to promote the nutritional value of cereal crops and increase their tolerance to biotic and abiotic stresses. This review critically discusses the activities of GET, the role of bioinformatics tools and its application to sustainable agriculture for cereal crops.

“…Over half of the world's population consumes rice ( Oryza sativa L.) as their primary food; for over 3.5 billion people, rice accounts for 20 % of their daily caloric intake ( Naomi and Ziska, 2019 , Rezk et al, 2023 ). Regardless, 90 % of the world's production comes from over 100 countries in Asia ( Bandumula, 2018 ).…”

Rice (Oryza sativa L.) is an essential food for half of the global population and is vital in maintaining global food security. Climate change, increasing population and recent incident of COVID pandemic has generated financial burden and threaten the global food security. Due to theses factors rice cultivation also has to face significant challenges. frequent weather changes pose a considerable challenge to agricultural planning, which was previously relaying on consistent seasonal variations. In this context, rice cultivation is particularly sensitive to cold, where its development and productivity inhibited by low temperatures (< 18 °C). Developing rice varietes with low temprature tolerence and good yield potential is one of the major goals of current breeding efforts of plant scientists. For this purpose, short duration and early rice varieties are most favorable to avoid cold stress and yield more in less number of days. this study was designed to investigate the effect of low temperatures on different rice varieties. the study was designed to identify low temprature tolerent genotypes with early and regular cultivation. For this, thirty-four genotypes were evaluated in two gorwing seasons (2018–2019) with four different sowing times. Statistically sowing time showed significant interaction between all yield contributing parameters. The data indicate that exposure to low temperatures during the reproductive phase prolongs the maturation period of the crop, also length of the panicle and the fertility of the spikelets drops, resulting in a significant decrease in the production of sensitive varieties. Some varieties are more sensitive to cold stress compared to others. In the Egyptian context, Giza176, Sakha104, and Sakha107 are recommended for early cultivation, while the genotypes Giza 179, Sakha101, Sakha104, and GZ 9730-1-1-1-1 are indicated for the normal cultivation period. The Sakha104 variety is particularly notable, as it is recommended for both purposes. In addition, the data obtained in this study provide valuable information for selecting rice varieties suitable for double cropping in the North Delta of Egypt. This study also contributes to the existing literature, providing insights into the resilience of rice cultivation in the face of climate change.
