| 1 | Phytophthora sojae Effector PsAvh240 Inhibits Host Aspartic Protease Secretion to Promote Infection显示文摘Plants secrete defense molecules into the extracellular space (the apoplast) to combat attacking microbes. However, the mechanisms by which successful pathogens subvert plant apoplastic immunity remain poorly understood. In this study, we show that PsAvh240, a membrane-localized effector of the soybean pathogen Phytophthora sojae, promotes P. sojae infection in soybean hairy roots. We found that PsAvh240 interacts with the soybean-resistant aspartic protease GmAP1 in planta and suppresses the secretion of GmAP1 into the apoplast. By solving its crystal structure we revealed that PsAvh240 contain six a helices and two WY motifs. The first two a helices of PsAvh240 are responsible for its plasma membrane-localization and are required for PsAvh240's interaction with GmAP1. The second WY motifs of two PsAvh240 molecules form a handshake arrangement resulting in a handshake-like dimer. This dimerization is required for the effector's repression of GmAP1 secretion. Taken together, these data reveal that PsAvh240 localizes at the plasma membrane to interfere with GmAP1 secretion, which represents an effective mechanism by which effector proteins suppress plant apoplastic immunity. | Baodian Guo Haonan Wang Bo Yang Wenjing Jiang Maofeng Jing Haiyang Li Yeqiang Xia Yuanpeng Xu Qinli Hu Fangfang Wang Feng Yu Yan Wang Wenwu Ye Suomeng Dong Weiman Xing Yuanchao Wang | 2019 | Molecular Plant2019,12,4: | 12 |
| 2 | A rejection sampling algorithm for off-centered discrete Gaussian distributions over the integers显示文摘Dear editor,Discrete Gaussian sampling,that is,sampling from a discrete Gaussian dist ribution Dwith parameterσ>0 and center c∈R^n over an ndimensional lattice A,has been considered by the cryptography research community as one of the fundamental building blocks of kittice-based cryptography[1,2].The simplest lattice is the onedimensional integer lattice Z.Sampling from a discrete Gaussian distribution DZ,σ,c over the integoTs Z,denoted by SampleZ,is an important sub-problem of discrete Gaussian sampling,where parameterσ>0 and ccnter c∈R. | Yusong DU Baodian WEI Huang ZHANG | 2019 | Science China(Information Sciences)2019,62,3: | 2 |
| 3 | RING PROXY SIGNATURES显示文摘Proxy signatures have been used to enable the transfer of digital signing power within some context and ring signatures can be used to provide the anonymity of a signer. By combining the functionalities of proxy signatures and ring signatures, this paper introduces a new concept, named ring proxy signature, which is a proxy signature generated by an anonymous member from a set of potential signers. The paper also constructs the first concrete ring proxy signature scheme based on the provably secure Schnorr's signatures and two ID-based ring proxy signature schemes. The security analysis is provided as well. | Wei Baodian Zhang Fangguo Chen Xiaofeng | 2008 | Journal of Electronics(China)2008,25,1: | 1 |
| 4 | The Phytophthora effector Avh241 interacts with host NDR1-like proteins to manipulate plant immunity显示文摘Plant pathogens rely on effector proteins to suppress host innate immune responses and facilitate colonization.Although the Phytophthora sojae RxLR effector Avh241 promotes Phytophthora infection,the molecular basis of Avh241 virulence remains poorly understood.Here we identified non-race specific disease resistance 1(NDR1)-like proteins,the critical components in plant effector-triggered immunity(ETI)responses,as host targets of Avh241.Avh241 interacts with NDR1 in the plasma membrane and suppresses NDR1-participated ETI responses.Silencing of GmNDR1s increases the susceptibility of soybean to P.sojae infection,and overexpression of GmNDR1s reduces infection,which supports its positive role in plant immunity against P.sojae.Furthermore,we demonstrate that GmNDR1 interacts with itself,and Avh241 probably disrupts the self-association of GmNDR1.These data highlight an effective counter-defense mechanism by which a Phytophthora effector suppresses plant immune responses,likely by disturbing the function of NDR1 during infection. | Bo Yang Sen Yang Baodian Guo Yuyin Wang Wenyue Zheng Mengjun Tian Kaixin Dai Zehan Liu Haonan Wang Zhenchuan Ma Yan Wang Wenwu Ye Suomeng Dong Yuanchao Wang | 2021 | Journal of Integrative Plant Biology2021,63,7: | 1 |
| 5 | Selectively unforgeable but existentially forgeable signature schemes and applications显示文摘This paper gives definitions,constructions and applications of signature schemes,which are selectively unforgeable but existentially forgeable(SUEF).We formalize the special notion under conditions of chosen message attack(CMA) and known message attack(KMA).Then two general constructions are presented with two concrete examples.We apply the SUEF secure signature schemes to an elementary authentication mechanism,the challenge-response mechanism,to obtain a basic deniable authentication method.The method is presented as a deniable message transmission(MT) authenticator in the extension framework of Raimondo. | TIAN HaiBo ZHANG FangGuo CHEN XiaoFeng WEI BaoDian | 2013 | Science China(Information Sciences)2013,56,1: | 1 |

| 8 | One AES S-box to increase complexity and its cryptanalysis显示文摘It is well known that the algebraic expression of ASS S-box is very simple and only 9 terms are involved. Hence, AES security is suspected although there is no vulnerability on it so far. To eliminate the weakness of extremely small terms in the algebraic expression of AES S-box, one improved AES S-box is proposed, which preserves the algebraic degree invariable but significantly increases the number of its algebraic expression terms from 9 to 255. At the same time, Boolean function has good characters in balance and strict avalanche criterion (SAC), etc. Finally, it is proved that the improved AES S-box scheme is secure gainst the powerful known differential and linear cryptanalysis. | Liu Jingmei Wei Baodian Wang Xinmei | 2007 | Journal of Systems Engineering and Electronics2007,18,2: | 1 |
