| 1 | RLINl,encoding a putative coproporphyrinogen Ⅲ oxidase,is involved in lesion initiation in rice显示文摘Lesion mimic is necrotic lesions on plant leaf or stem in the absence of pathogenic infection,and its exact biological mechanism is varied.By a large-scale screening of our T-DNA mutant population,we identified a mutant rice lesion initiation 1(rlin1),which was controlled by a single nuclear recessive gene.Map-based cloning revealed that RLIN1 encoded a putative coproporphyrinogen Ⅲ oxidase in tetrapyrrole biosynthesis pathway.Sequencing results showed that a G to T substitution occurred in the second exon of RLIN1 and led to a missense mutation from Asp to Tyr.Ectopic expression of RLIN1 could rescue rlin1 lesion mimic phenotype.Histochemical analysis demonstrated that lesion formation in rlin1 was light-dependent accompanied by reactive oxygen species accumulated.These results suggest that tetrapyrrole participates in lesion formation in rice. | Changhui Sun Linchuan Liu Jiuyou Tang Aihong Lin Fantao Zhang Jun Fang Genfa Zhang Chengcai Chu | 2011 | Journal of Genetics and Genomics2011，38，1： | 31 |
| 2 | H_2O_2-induced Leaf Cell Death and the Crosstalk of Reactive Nitric/Oxygen Species显示文摘In plants, the chloroplast is the main reactive oxygen species (ROS) producing site under high light stress. Catalase (CAT), which decomposes hydrogen peroxide (H2O2), is one of the controlling enzymes that maintains leaf redox homeostasis. The catalase mutants with reduced leaf catalase activity from different plant species exhibit an H2O2-induced leaf cell death phenotype. This phenotype was differently affected by light intensity or photoperiod, which may be caused by plant species, leaf redox status or growth conditions. In the rice CAT mutant nitric oxide excess 1 (noe1), higher H2O2 levels induced the generation of nitric oxide (NO) and higher S-nitrosothiol (SNO) levels, suggesting that NO acts as an important endogenous mediator in H2O2-induced leaf cell death. As a free radical, NO could also react with other intracellular and extracellular targets and form a series of related molecules, collectively called reactive nitrogen species (RNS). Recent studies have revealed that both RNS and ROS are important partners in plant leaf cell death. Here, we summarize the recent progress on H2O2-induced leaf cell death and the crosstalk of RNS and ROS signals in the plant hypersensitive response (HR), leaf senescence, and other forms of leaf cell death triggered by diverse environmental conditions. | Yiqin Wang Aihong Lin Gary J.

| 3 | Three-Dimensional Water Quality Model Based on FVCOM for Total Load Control Management in Guan River Estuary,Northern Jiangsu Province显示文摘Guan River Estuary and adjacent coastal area(GREC) suffer from serious pollution and eutrophicational problems over the recent years.Thus,reducing the land-based load through the national pollutant total load control program and developing hydrodynamic and water quality models that can simulate the complex circulation and water quality kinetics within the system,including longitudinal and lateral variations in nutrient and COD concentrations,is a matter of urgency.In this study,a three-dimensional,hydrodynamic,water quality model was developed in GREC,Northern Jiangsu Province.The complex three-dimensional hydrodynamics of GREC were modeled using the unstructured-grid,finite-volume,free-surface,primitive equation coastal ocean circulation model(FVCOM).The water quality model was adapted from the mesocosm nutrients dynamic model in the south Yellow Sea and considers eight compartments:dissolved inorganic nitrogen,soluble reactive phosphorus(SRP),phytoplankton,zooplankton,detritus,dissolved organic nitrogen(DON),dissolved organic phosphorus(DOP),and chemical oxygen demand.The hydrodynamic and water quality models were calibrated and confirmed for 2012 and 2013.A comparison of the model simulations with extensive dataset shows that the models accurately simulate the longitudinal distribution of the hydrodynamics and water quality.The model can be used for total load control management to improve water quality in this area. | ZHANG Li LIN Weibo LI Keqiang SHENG Jianming WEI Aihong LUO Feng WANG Yan WANG Xiulin ZHANG Longjun | 2016 | Journal of Ocean University of China2016，15，2： | 1 |

| 6 | The Application of Acidic Electrolyzed Water to Grape Cultivation in the Southern Regions显示文摘Experimental studies have shown that AEW( Acidic Electrolyzed Water) plays a strong role in killing grape virus,and it has instantaneous,broad-spectrum,efficient,safe and non-residual fungicidal properties. The results show that spraying AEW,and spraying alkaline electrolyzed water first and then AEW,can play a good role in controlling the virus damage of grape downy mildew,Botrytis cinerea,anthracnose,grape Alternaria spot,and anthrachose of grape,with foliar control effect of 93. 5%,96. 2%,93. 20%,100% and 87. 9%,respectively,and ear control effect of 88%,92%,84%,84% and 72%,respectively. AEW can replace pesticide,and can promote the average grape weight and sugar degree. | Haihua TU Naixiong TANG Nianqian KANG Jian ZHOU Aihong LIN | 2016 | Asian Agricultural Research2016，8，7： | 0 |
| 7 | Design of an Active Flexible Spine for Wall Climbing Robot Using Pneumatic Soft Actuators显示文摘Wall climbing robots can be used to undertake missions in many unstructured environments.However,current wall climbing robots have mobility difficulties such as in the turning or accelarating.One of the main reasons for the limitations is the poor flexibility of the spines.Soft robotic technology can actively enable structure deformation and stiffness varations,which provides a solution for the design of active flexible spines.This research utilizes pneumatic soft actuators to design a flexible spine with the abilities of actively bending and twisting by each joint.Using bending and torsion moment equilibriums,respectively,from air pressure to material deformations,the bending and twisting models for a single actuator with respect to different pressure are obtained.The theoretical models are verified by finite-element method simulations and experimental tests.In addition,the bending and twisiting motions of single joint and whole spine are analytically modeled.The results show that the bionic spine can perform desired deformations in accordance with the applied pressure on specified chambers.The variations of the stiffness are also numerically assessed.Finally,the effectiveness of the bionic flexible spine for actively producing sequenced motions as biological spine is experimentally validated.This work demonstrated that the peneumatic spine is potential to improve the spine flexibility of wall climbing robot. | Guangming Chen Tao Lin Gabriel Lodewijks Aihong Ji | 2023 | Journal of Bionic Engineering2023，20，2： | 0 |
