Abstract

CRISPR–Cas genome editing technology developed from prokaryotes has transformed the molecular biology of plants past all assumptions. CRISPR–Cas, which is distinguished by its resilience, relatively high specificity, and easy implementation, enables specific genetic modification of crops, allowing for the creation of germplasms with favorable characters and the development of innovative, highly efficient agricultural systems. Moreover, many new biotechnologies in the framework of CRISPR–Cas platforms have bolstered basic research as well as synthetic biology toolkit of plants. In this article, initially, we provide a brief overview of CRISPR–Cas gene editing, emphasis on the modern, most specific gene-editing techniques, such as prime and base editing. Following that, the major role of CRISPR–Cas in plants in enhancing pesticide and disease resistance, quality, yield, breeding, and faster domestication are next discussed. In this review, we discuss the current advancements in plant biotechnology linked to CRISPR–Cas, such as CRISPR–Cas gene control, reagent conveyance, multiplexed gene editing, directed evolution, and mutagenesis. In the end, we talk about how this innovative technology may be used in the future.
