The New Strategy for Disease Resistance Sugarcane（Saccharum officinarum L.） Breeding Based on Pathogenic-effect Proteins

Sugarcane（Saccharum officinarum L.） diseases are important factors restricting the growth of sugarcane and the development of the sugarcane industry, and the selection and promotion of sugarcane disease-resistant varieties is an effective means for the high-quality and sustainable development of the sugarcane industry. However, the traditional breeding of sugarcane disease-resistant varieties has limitations, such as difficulties in the mining of high-quality genes and the validation of their functions. Effector proteins are small-molecule proteins secreted by pathogenic bacteria to assist their colonization of the host, and analyzing the interaction between pathogenic bacterial effector proteins and the plant immune system is of great significance in guiding the improvement of disease-resis-tant varieties in sugarcane. This review discusses the response network of the host immune system and the related strategies of pathogens to evade or destroy the host immune system by secreting effector proteins to successfully colonize the infection, and based on this, suggests related ideas for designing and adapting new disease-resistant varieties of sugarcane.
