| 1 | Interference of CsGPA1,theα-submit of G protein,reduces drought tolerance in cucumber seedlings显示文摘The G proteinα-subunit,GPA1,is an integral component of several signaling pathways in plants,including response to abiotic stress.However,the molecular mechanism behind these processes remains largely unknown in the cucumber plant(Cucumis sativus L.).In order to further understand the role of CsGPA1 in cucumber under drought stress,changes in plant growth,physiological parameters,and gene expression of CsAQPs were all measured under water stress induced by polyethylene glycol(PEG)using wild type(WT)and CsGPA1-interference(RNAi)cucumber seedlings.Our results demonstrated that the RNAi plants had lower drought tolerance,displaying seriously withered leaves,lower relative growth rate,lower root-shoot ratio,and lower root activity under drought stress compared to WT plants.Physiological studies indicated that the suppression of CsGPA1 weakened drought stress tolerance due to higherwater loss rate in the leaves,higher levels of hydrogen peroxide(H2O2),increased malondialdehyde(MDA)content,lower free proline content,lower soluble sugar content,lower soluble protein content,and decreased antioxidant enzyme activities.qRT-PCR analysis demonstrated that the interference of CsGPA1 up-regulated the expression of most AQP genes(except for CsPIP2;3 in leaves)and down-regulated the expression of CsPIP1;2,CsPIP1;4,CsPIP2;1,and CsPIP2;4 in roots under drought stress when compared to WT plants.Our results demonstrated that CsGPA1 could function as a positive regulator in drought stress response by decreasing the accumulation of reactive oxygen species(ROS),improving permeable potentials,and reducing water loss in cucumber plants. | Yumei Liu Qinghua Du Longqiang Bai Mintao Sun Yansu Li Chaoxing He Jun Wang Xianchang Yu Yan Yan | 2021 | Horticultural Plant Journal2021，7，3： | 3 |
| 2 | Multifaceted regulatory functions of CsBPC2 in cucumber under salt stress conditions显示文摘BASIC PENTACYSTEINE(BPC)transcription factors are essential regulators of plant growth and development.However,BPC functions and the related molecular mechanisms during cucumber(Cucumis sativus L.)responses to abiotic stresses,especially salt stress,remain unknown.We previously determined that salt stress induces CsBPC expression in cucumber.In this study,Csbpc2 transgene-free cucumber plants were created using a CRISPR/Cas9-mediated editing system to explore CsBPC functions associated with the salt stress response.The Csbpc2 mutants had a hypersensitive phenotype,with increased leaf chlorosis,decreased biomass,and increased malondialdehyde and electrolytic leakage levels under salt stress conditions.Additionally,a mutated CsBPC2 resulted in decreased proline and soluble sugar contents and antioxidant enzyme activities,which led to the accumulation of hydrogen peroxide and superoxide radicals.Furthermore,the mutation to CsBPC2 inhibited salinity-induced PM-H+-ATPase and V-H+-ATPase activities,resulting in decreased Na+efflux and increased K+efflux.These findings suggest that CsBPC2 may mediate plant salt stress resistance through its effects on osmoregulation,reactive oxygen species scavenging,and ion homeostasis-related regulatory pathways.However,CsBPC2 also affected ABA signaling.The mutation to CsBPC2 adversely affected salt-induced ABA biosynthesis and the expression of ABA signaling-related genes.Our results indicate that CsBPC2 may enhance the cucumber response to salt stress.It may also function as an important regulator of ABA biosynthesis and signal transduction.These findings will enrich our understanding of the biological functions of BPCs,especially their roles in abiotic stress responses,thereby providing the theoretical basis for improving crop salt tolerance. | Shuzhen Li Mintao Sun Li Miao Qinghua Di Lijun Lv Xianchang Yu Yan Yan Chaoxing He Jun Wang Aokun Shi Yansu Li | 2023 | Horticulture Research2023，10，5： | 0 |
| 3 | Effects of Two Kinds of Arbuscular Mycorrhizal Fungi (AMF) Inoculums on Cucumber Seedlings Growth显示文摘To study the effects of AMF( arbuscular mycorrhizal fungi) inoculums on seedling growth of cucumber,vegetable seeds were inoculated with two kinds of AMF inoculums BF( mycorrhiza for plants) and VT( mycorrhiza for vegetables) from Czech Republic during sowing in trays in greenhouse. The root AMF infection rates in seedlings were 49. 30% and 37. 65% respectively after 35 d growth. The plant height,stem diameter,fresh and dry weight of those seedlings inoculated with BF and VT were higher than that in CK. Compared with the CK,VT inoculation significantly improved the root activity,chlorophyll content and photosynthetic rate of cucumber seedlings. Comprehensive analysis showed that VT could promote seedling growth of protected cucumber. | Sun Xiuxiu Jin Wenjuan Li Yansu Yan Yan Yu Xianchang He Chaoxing | 2016 | Plant Diseases and Pests2016，7，5： | 0 |
| 4 | Self-powered flexible fingerprint-recognition display based on a triboelectric nanogenerator显示文摘In the time of Internet of Things(IoT),alternating current electroluminescence(ACEL)has unique advantages in the fields of smart display and human–computer interaction.However,their reliance on external high-voltage AC power supplies poses challenges in terms of wearability and limits their practical application.This paper proposed an innovative scheme for preparing a feather triboelectric nanogenerator(F-TENG)using recyclable and environmentally friendly material.The highest open-circuit voltage,short-circuit current,and transferred charge of SF6-treated F-TENGs can reach 449 V,63μA,and 152 nC,which enables easy lighting of BaTiO_(3)^(-)doped ACEL devices.Using a human electrical potential,a single-electrode F-TENG is combined with ACEL device for self-powered fingerprint recognition display.These works achieve self-powered flexible wearable ACEL devices,which are not only efficient and portable but also have good application prospects in the human–computer interaction,functional displays,and wearable electronic devices. | Wandi Chen Haonan Wang Yibin Lin Xinyan Gan Heng Tang Yongai Zhang Qun Yan Tailiang Guo Xiongtu Zhou Chaoxing Wu | 2024 | Nano Research2024，17，4： | 0 |
| 5 | Timing Synchronization and Ranging in Networked UAV-Aided OFDM Systems显示文摘The space-air-ground network architecture integrates satellite systems,aerial networks,and terrestrial networks,where the unmanned aerial vehicle(UAV)communication in the air segment has attracted particular interest and demonstrated tremendous potential in both military and civilian applications.Orthogonal frequency division multiplexing(OFDM)can be an effective solution to provide high rate and reliable transmission in UAV communication systems because of its high spectral efficiency and robustness against frequency selective fading.We herein focus our attention on two critical issues in our proposed UAV aided OFDM system,i.e.,timing synchronization and ranging.Moreover,extensive simulations are conducted for evaluation.Finally,we design a real-world field test for verifying the effectiveness of our proposed multi-UAV OFDM communication system. | Chaoxing Yan Jingjing Wang Lingang Fu Chunxiao Jiang Ming Chen Yong Ren | 2018 | Journal of Communications and Information Networks2018，3，4： | 0 |
