Plants usually keep resistance(R)proteins in a static state under normal conditions to avoid autoimmunity and save energy for growth,but R proteins can be rapidly activated upon perceiving pathogen invasion.Pib,the first cloned blast disease R gene in rice,encoding a nucleotide-binding leucine-rich repeat(NLR)protein,mediates resistance to the blast fungal(Magnaporthe oryzae)isolates carrying the avirulence gene AvrPib.However,the molecular mechanisms about how Pib recognizes AvrPib and how it is inactivated and activated remain largely unclear.In this study,through map-based cloning and CRISPR-Cas9 gene editing,we proved that Pib contributes to the blast disease resistance of rice cultivar Yunyin(YY).Furthermore,an SH3 domain-containing protein,SH3P2,was found to associate with Pib mainly at clathrin-coated vesicles in rice cells,via direct binding with the coiled-coil(CC)domain of Pib.Interestingly,overexpression of SH3P2 in YY compromised Pib-mediated resistance to M.oryzae isolates carrying AvrPib and Pib-AvrPib recognition-induced cell death.SH3P2 competitively inhibits the self-association of the Pib CC domain in vitro,suggesting that binding of SH3P2 with Pib undermines its homodimerization.Moreover,SH3P2 can also interact with AvrPib and displays higher affinity to AvrPib than to Pib,which leads to dissociation of SH3P2 from Pib in the presence of AvrPib.Taken together,our results suggest that SH3P2 functions as a“protector”to keep Pib in a static state by direct interaction during normal growth but could be triggered off by the invasion of AvrPib-carrying M.oryzae isolates.Our study reveals a new mechanism about how an NLR protein is inactivated under normal conditions but is activated upon pathogen infection.

Global food security is threatened by rice blast disease caused by the filamentous fungus Magnaporthe oryzae.An understanding of rice resistance mechanisms is fundamental to developing strategies for disease control.In this review,we summarize recent advances in pathogen-associated molecular pattern-triggered immunity,effector-triggered immunity,defense regulator-mediated immunity,and effects of nutrient elements on rice blast resistance.We outline strategies used for breeding rice cultivars with improved disease resistance.We also present the major research challenges for rice blast disease resistance and propose approaches for future investigation.

Plant Diseases and Pests 2017年第2期8卷 26-33页

作者： Wang Hui Su Yuan Liu Chao Wang Yi Yang Jing Li Chengyun State Key Laboratory for Conservation and Utilization of Bio-Resources in Yunnan Yunnan Agricultural University

The structure similarity of secreted proteins in rice blast fungus Magnaporthe oryzae and its host Oryza sativa was analyzed. One thousand two hundred and forty one proteins were predicted as secreted proteins using four algorithms based on 11 074 proteins in genome of M. oryzae. One hundred and forty six secreted proteins（ 11. 8% of M. oryzae secretome） were aligned with 116 rice proteins（ 0. 21% of 56 278 rice proteins） using blast search on rice genome. One hundred sixteen rice similar proteins participated in rice cell wall modification（ cell wall associated enzymes） and signal transduction（ proteases）. These results imply that both cell wall involved proteins and signal transduction are probably hijacks pathway between host pants and pathogenic fungi. Because these proteins are highly conserved among fungi and plants,the express patterns of these protein coding genes during the interaction process are valuable to study in detail.

应用我国7个鉴别品种,鉴定了1980～1981年由我省7个地区37个县（市）采集分离的387个有效单孢菌株,区分为7群29个小种,其中ZB群为优势小种群,ZB;为优势小种。 1975～1978年福建省稻瘟病菌生理小种区系组成相似,至1981年便发生了变化。... 详细信息

应用我国7个鉴别品种,鉴定了1980～1981年由我省7个地区37个县（市）采集分离的387个有效单孢菌株,区分为7群29个小种,其中ZB群为优势小种群,ZB;为优势小种。 1975～1978年福建省稻瘟病菌生理小种区系组成相似,至1981年便发生了变化。但主要小种类型并无什么变化,而是小种组成比和地理分布范围的变更。其特点是侵染我省大面积栽培的珍尢系统品种的ZB群小种迅速增加,地理分布范围扩大。至1981年全省7个地区均以ZB群为优势小种群,ZB;上升为优势小种,取代了过去致病力弱的优势小种ZG;。文中还对稻瘟病菌的变异和稳定性作了讨论。关键词:稻瘟病菌;生理小种;中国鉴别品种;珍龙系统品种实践证明,利用抗病品种是防治稻瘟病的一项经济有效的措施,但品种抗性与稻瘟病菌的变异、小种区系组成的变化密切相关。因此,稻瘟病菌生理小种区系组成的变化及其消长规律的研究,是抗瘟育种品种布局和品种坑性变化预测的重要基础工作。在1973～1978年对我省稻瘟病菌生理小种研究的基础上,本文报导了1980～1981年福建稻瘟病菌生理小种的鉴定和1978、1981年小种区系组成的变化情况。
