[Advances in genome editing and lodging resistance in sugarcane].

Sugarcane (Saccharum spp.) is an important cash crop that provides about 90% of sugar and 40% of bioethanol in China. Due to its large genome and complicated genetic background, conventional breeding is difficult to achieve efficient genetic improvement of sugarcane. Genome editing is a disruptive technology in life sciences, enabling precise and efficient modification of target genes. From zinc-finger nucleases (ZFNs) to transcription activator-like effector nucleases (TALENs), the CRISPR/Cas system and the derived base editing and prime editing, these technologies have greatly advanced genetic research and upgraded biological breeding. With the decoding of the sugarcane genome, genome editing has provided a new technical means for the genetic improvement of polyploid sugarcane. This article provides a comprehensive review of the trajectory of genome editing in plants, the optimization of the CRISPR/Cas system, the genetic transformation status of sugarcane, the development of sugarcane genomics, and the application of genome editing in sugarcane. It focuses on exploring the application prospects of genome editing in breeding lodging-resistant sugarcane varieties. This review aims to provide valuable references for promoting the use of genome editing in sugarcane breeding.
