| 1 | A 2-kb Mycovirus Converts a Pathogenic Fungus into a Beneficial Endophyte for Brassica Protection and Yield Enhancement显示文摘Mycoviruses are viruses that infect fungi,and hypovirulence-associated mycoviruses have the potential to control fungal diseases.However,it is unclear how mycovirus-mediated hypovirulent strains live and survive in the field,and no mycovirus has been applied for field crop protection.In this study,we found that a previously identified small DNA mycovirus(SsHADV-1)can convert its host,Sclerotinia sclerotiorum,from a typical necrotrophic pathogen to a beneficial endophytic fungus.SsHADV-1 downregulates the expression of key pathogenicity factor genes in S.sclerotiorum during infection.When growing in rapeseed,the SsHADV-1-infected strain DT-8 significantly regulates the expression of rapeseed genes involved in defense,hormone signaling,and circadian rhythm pathways.As a result,plant growth is promoted and disease resistance is enhanced.Field experiments showed that spraying DT-8 at the early flowering stage can reduce the disease severity of rapeseed stem rot by 67.6%and improve yield by 14.9%.Moreover,we discovered that SsHADV-1 could also infect other S.sclerotiorum strains on DT-8-inoculated plants and that DT-8 could be recovered from dead plants.These findings suggest that the mycoviruses may have the ability to shape the origin of endophytism.Our discoveries suggest that mycoviruses may influence the origin of endophytism and may also offer a novel strategy for disease control in which mycovirus-infected strains are used to improve crop health and release mycoviruses into the field. | Hongxiang Zhang Jiatao Xie Yanping Fu Jiasen Cheng Zheng Qu Zhenzhen Zhao Shufen Cheng Tao Chen Bo Li Qianqian Wang Xinqiang Liu Binnian Tian David B.Collinge Daohong Jiang | 2020 | Molecular Plant2020，13，10： | 9 |

| 3 | INTEGRAL EQUATION METHOD'S APPLICATION IN HOLE-EDGE STRESS OF COMPOSITE MATERIAL PLATE WITH DIFFERENT SHAPED HOLES显示文摘The strength of composite plate with different hole-shapes is always one of the most important but complicated issues in the application of the composite material.The holes will lead to mutations and discontinuity to the structure.So the hole-edge stress concentration is always a serious phenomenon.And the phenomenon makes the structure strength decrease very quickly to form dangerous weak points.Most partial damage begins from these weak points.According to the complex variable functions theory,the accurate boundary condition of composite plate with different hole-shapes is founded by conformal mapping method to settle the boundary condition problem of complex hole-shapes.Composite plate with commonly hole-shapes in engineering is studied by several complex variable stress function.The boundary integral equations are founded based on exact boundary conditions.Then the exact hole-edge stress analytic solution of composite plate with rectangle holes and wing manholes is resolved.Both of offset axis loadings and its influences on the stress concentration coefficient of the hole-edge are discussed.And comparisons of different loads along various offset axis on the hole-edge stress distribution of orthotropic plate with rectangle hole or wing manhole arc madc.It can bc concluded that hole-edge with continuous variable curvatures might help to decrease the stress concentration coefficient;and smaller angle of outer load and fiber can decrease the stress peak value. | LI Cheng ZHENG Yanping | 2008 | Chinese Journal of Mechanical Engineering2008，21，6： | 3 |

| 6 | Nitrogen‐doped tin oxide electron transport layer for stable perovskite solar cells with efficiency over 23%显示文摘Tin oxide has made a major breakthrough in high-efficiency perovskite solar cells(PSCs)as an efficient electron transport layer by the low-temperature chemical bath deposition method.However,tin oxide often contains pernicious defects,resulting in unsatisfactory performance.Herein,we develop high-quality tin oxide films via a nitrogen-doping strategy for high-efficiency and stable planar PSCs.The aligned energy level at the interface of doped SnO_(2)/perovskite,more excellent charge extraction and reduced nonradiative recombination contribute to the enhanced efficiency and stability.Correspondingly,the power conversion efficiency of the devices based on N‐SnO_(2) film increases to 23.41% from 20.55% of the devices based on the pristine SnO_(2).The N-SnO_(2) devices show an outstanding stability retaining 97.8% of the initial efficiency after steady-state output at a maximum power point for 600s under standard AM1.5G continuous illumination without encapsulation,while less than 50% efficiency remains for the devices based on pristine SnO_(2).This simple scalable strategy has shown great promise toward highly efficient and stable PSCs. | Yanping Mo Chao Wang Xuntian Zheng Peng Zhou Jing Li Xinxin Yu Kaizhong Yang Xinyu Deng Hyesung Park Fuzhi Huang Yi‐Bing Cheng | 2022 | Interdisciplinary Materials2022，1，2： | 0 |
