CRISPR/Cas9-mediated genome editing techniques and new breeding strategies in cereals – current status, improvements, and perspectives

Biotechnology Advances, Год журнала: 2023, Номер 69, С. 108248 - 108248

Опубликована: Сен. 2, 2023

Cereal crops, including triticeae species (barley, wheat, rye), as well edible cereals (wheat, corn, rice, oat, rye, sorghum), are significant suppliers for human consumption, livestock feed, and breweries. Over the past half-century, modern varieties of cereal crops with increased yields have contributed to global food security. However, presently cultivated elite crop were developed mainly optimal environmental conditions. Thus, it has become evident that taking into account ongoing climate changes, currently a priority should be given developing new stress-tolerant cultivars. It is necessary enhance accuracy methods time required generate cultivars desired features adapt change keep up world population expansion. The CRISPR/Cas9 system been powerful versatile genome editing tool achieve desirable traits, such high-yielding, stress-tolerant, disease-resistant transgene-free lines in major cereals. Despite recent advances, application faces several challenges, amount develop lines, laboriousness, limited number genotypes may used transformation vitro regeneration. Additionally, through restricted many countries, especially Europe New Zealand, due lack flexibility GMO regulations. This review provides comprehensive update researchers interested improving using gene-editing technologies, CRISPR/Cas9.
