| 摘 要： | 类病变突变体是植物在无显著逆境或损伤情况下以及未受到病原物危害时叶片上自然形成的类似病斑的一类突变体。水稻类病变突变体的产生常伴有抗病性的增强,其中涉及到防御相关基因的表达。相关研究主要集中于各种突变体的定位和克隆以及突变体的抗病性和抗病机制。综述了水稻类病变突变基因的性状及抗病性的研究进展,特别是对水稻类病变突变体形成原因、遗传特性、调控途径进行了梳理,并提出对水稻抗病育种的展望,以期为进一步分析类病变突变体的各种机制奠定理论基础,并为水稻育种提供参考。

| Abstract: | Lesion mimic mutants are similar with naturally-formed scab on rice leaves without significant stress or damage and without exposure to pathogens. The cause of lesion mimic traits in rice is often accompanied by increased resistance to disease, which involves the expression of defense-related genes. The related research mainly focuses on the localization and cloning of various mutants, as well as the disease resistance and its mechanism. We reviewed the research progress in lesion mimic mutant gene traits and disease resistance in rice, especially explaining the causes, genetic characteristics and regulatory pathways of lesion mimic mutants in rice, and expecting to improve rice breeding for disease resistance as well. All these will lay a theoretical foundation for further analysis of various mechanisms of lesion mimic mutants and providing some reference for rice breeding. |
