Rice is one of the important crops grown worldwide and is considered as an important crop for global food security. Rice is being affected by various fungal, bacterial and viral diseases resulting in huge yield losses every year. Deployment of resistance genes in various crops is one of the important methods of disease management. However, identification, cloning and characterization of disease resistance genes is a very tedious effort. To increase the life span of resistant cultivars, it is important to understand the molecular basis of plant host-pathogen interaction. With the advancement in rice genetics and genomics, several rice varieties resistant to fungal, bacterial and viral pathogens have been developed. However, resistance response of these varieties break down very frequently because of the emergence of more virulent races of the pathogen in nature. To increase the durability of resistance genes under field conditions, understanding the mechanismof resistance response and its molecular basis should be well understood. Some emerging concepts like interspecies transfer of pattern recognition receptors (PRRs) and transgenerational plant immunitycan be employed to develop sustainable broad spectrum resistant varieties of rice.
水稻是世界上重要的粮食作物之一，被认为是全球粮食安全的重要作物。水稻受到各种真菌、细菌和病毒病害的影响，每年因此导致大量减产。在各种作物中部署抗性基因是病害管理的重要方法之一。然而，抗病基因的鉴定、克隆和特征描述是一项非常繁琐的工作。为了增加抗性品种的使用寿命，了解植物-病原体相互作用的分子基础非常重要。随着水稻遗传学和基因组学的进步，已经开发出了几种对真菌、细菌和病毒病原体具有抗性的水稻品种。然而，由于自然界中病原体毒性更强的菌株的出现，这些品种的抗性反应经常失效。为了在田间条件下提高抗性基因的耐久性，应该充分了解抗性反应的机制及其分子基础。可以采用一些新出现的概念，如种间模式识别受体 (PRRs) 的转移和跨代植物免疫，来开发可持续的广谱抗水稻品种。
