| 1 | Pm67, a new powdery mildew resistance gene transferred from Dasypyrum villosum chromosome 1V to common wheat(Triticum aestivum L.)显示文摘Powdery mildew, caused by the biotrophic fungus Blumeria graminis f. sp. tritici(Bgt), is a global disease that poses a serious threat to wheat production. To explore additional resistance gene, a wheatDasypyrum villosum 1 V#5(1 D) disomic substitution line NAU1813(2 n = 42) with high level of seedling resistance to powdery mildew was used to generate the recombination between chromosomes 1 V#5 and1 D. Four introgression lines, including t1 VS#5 ditelosomic addition line NAU1815, t1 VL#5 ditelosomic addition line NAU1816, homozygous T1 DL·1 VS#5 translocation line NAU1817, and homozygous T1 DS·1 VL#5 translocation line NAU1818 were developed from the selfing progenies of 1 V#5 and 1 D double monosomic line that derived from F1 hybrids of NAU1813/NAU0686. All of them were characterized by fluorescence in situ hybridization, genomic in situ hybridization, 1 V-specific markers analysis, and powdery mildew tests at different developmental stages. A new powdery mildew resistance gene named Pm67 was physically located in the terminal bin(FL 0.70–1.00) of 1 VS#5. Lines with Pm67 exhibited seedling stage immunity and tissue-differentiated reactions at adult plant stage. The sheaths, stems, and spikes of the Pm67 line were still immune, but the leaves showed a low degree of susceptibility.Microscopic observation showed that most penetration attempts were stopped in association with papillae on the sheath, and colonies cannot form conidia on the susceptible leaf of Pm67 line at adult plant stage, suggesting that the defence layers of the Pm67 line is tissue-differentiated. Thus, the T1 DL·1 VS#5 translocation line NAU1817 provides a new germplasm in wheat breeding for improvement of powdery mildew resistance. | Ruiqi Zhang Chuanxi Xiong Huanqing Mu Ruonan Yao Xiangru Meng Lingna Kong Liping Xing Jizhong Wu Yigao Feng Aizhong Cao | 2021 | The Crop Journal2021，9，4： | 3 |

| 7 | Production,purification and activity evaluation of three novel antioxidant peptides obtained from grass carp(Ctenopharyngodon idella)scale waste by microbial protease BaApr1 hydrolysis显示文摘In this study,an alkaline protease BaApr1 from the Bacillus altitudinis W3 was chosen to hydrolysis grass carp(Ctenopharyngodon idella)scales.The hydrolysate of alkaline protease BaApr1 exhibited the best antioxidant activity compared to other protease hydrolysates.The optimal hydrolysis conditions for BaApr1 were an enzyme dosage of 1250 U/g,a hydrolysis time of 7 h,a pH of 9.5 and a temperature of 50℃.Three novel peptides were purified using ultrafiltration,anion exchange chromatography,gel filtration chromatography and ultra-performance liquid chromatography,and their sequences were identified as Tyr-Val-Gln-Ala-Gly-Ala-Ala-Gly-Ala-Ala-Ala-His(SHP2),Val-Lys-Leu-Tyr-Val-Leu-Leu-Val-Pro(SHP4),and Val-Gln-Val-Leu-Ala-Gly-Pro-Val-Val-Lys-Leu-Tyr(SHP5)with molecular weights of 1086.53 Da,1043.69 Da and 1285.79 Da,respectively.Among them,SHP2 exhibited the highest scavenging activity on DPPH;(EC_(50)4.08 mg/mL),ABTS+;(EC_(50)0.23 mg/mL)and HO;(EC_(50)2.78 mg/mL),and the strongest reducing power.Additionally,SHP5 can significantly inhibit lipid peroxidation in the linoleic acid system.In conclusion,three peptides isolated from scales of hydrolysate of grass carp showed great antioxidant activity and might be used as potential food ingredients and pharmaceuticals. | Shuang Li Qiaopeng Tian Tiantian Meng Zhengbing Guan Yujie Cai Xiangru Liao | 2022 | Systems Microbiology and Biomanufacturing2022，2，3： | 1 |
| 8 | Quorum systems for intrusion-tolerance based on trusted timely computing base显示文摘Quorum systems have been used to solve the problem of data consistency in distributed fault-tolerance systems. But when intrusions occur, traditional quorum systems have some disadvantages. For example, synchronous quorum systems are subject to DOS attacks, while asynchronous quorum systems need a larger system size (at least 3f+1 for generic data, and f fewer for self-verifying data). In order to solve the problems above, an intrusion-tolerance quorum system (ITQS) of hybrid time model based on trust timely computing base is presented (TTCB). The TTCB is a trust secure real-time component inside the server with a well defined interface and separated from the operation system. It is in the synchronous communication environment while the application layer in the server deals with read-write requests and executes update-copy protocols asynchronously. The architectural hybridization of synchrony and asynchrony can achieve the data consistency and availability correctly. We also build two kinds of ITQSes based on TTCB, i.e., the symmetrical and the asymmetrical TTCB quorum systems. In the performance evaluations, we show that TTCB quorum systems are of smaller size, lower load and higher availability. | Hua Zhou Xiangru Meng Li Zhang Xiangdong Qiao | 2010 | Journal of Systems Engineering and Electronics2010，21，1： | 0 |
