Rice () is a globally important crop that plays a central role in maintaining food security. This scientific review examines the critical role of genetic disease resistance in protecting rice yields, dissecting at the molecular level how rice plants detect and respond to pathogen attacks while evaluating modern approaches to developing improved resistant varieties. The analysis covers single-gene-mediated and multi-gene resistance systems, detailing how on one hand specific resistance proteins, defense signaling components, and clustered loci work together to provide comprehensive protection against a wide range of pathogens and yet their production is severely impacted by pathogens such as (bacterial blight) and (rice blast). The discussion extends to breakthrough breeding technologies currently revolutionizing rice improvement programs, including DNA marker-assisted selection for accelerating traditional breeding, gene conversion methods for introducing new resistance traits, and precision genome editing tools such as CRISPR/Cas9 for enabling targeted genetic modifications. By integrating advances in molecular biology and genomics, these approaches offer sustainable solutions to safeguard rice yields against evolving pathogens.
水稻是一种在全球具有重要地位的作物,在保障粮食安全方面发挥着核心作用。本科学综述探讨了遗传抗病性在保护水稻产量方面的关键作用,从分子层面剖析水稻植株如何检测并应对病原体攻击,同时评估培育改良抗病品种的现代方法。分析涵盖单基因介导和多基因抗性系统,详细阐述了一方面特定抗性蛋白、防御信号成分和簇状基因座如何协同作用,为抵御多种病原体提供全面保护,但另一方面它们的产生又受到诸如稻瘟病菌(稻瘟病)和水稻白叶枯病菌(白叶枯病)等病原体的严重影响。讨论还延伸至当前正在彻底改变水稻改良计划的突破性育种技术,包括用于加速传统育种的DNA标记辅助选择、用于引入新抗性性状的基因转化方法以及诸如CRISPR/Cas9等用于进行靶向基因修饰的精确基因组编辑工具。通过整合分子生物学和基因组学的进展,这些方法为保护水稻产量免受不断进化的病原体侵害提供了可持续的解决方案。
