| 1 | Intra-annual stem diameter growth of Tamarix ramosissima and association with hydroclimatic factors in the lower reaches of China's Heihe River显示文摘High-resolution observations of cambial phenology and intra-annual growth dynamics are useful approaches for understanding the response of tree growth to climate and environmental change. During the past two decades, rapid socioeconomic development has increased the demand for water resources in the oases of the middle reaches of the Heihe River in northwestern China, and the lower reaches of the Heihe River have changed from a perennial river to an ephemeral stream with a decreased and degraded riparian zone. Tamarisk(Tamarix ramosissima) is the dominant shrub species of the desert riparian forest. In this study, the daily and seasonal patterns of tamarisk stem diameter growth, including the main period of tree ring formation, were examined. Observations concerning the driving forces of growth changes, along with implications for the ecology of the dendrohydrological area and management of desert riparian forests in similar arid regions, are also presented. The diurnal-seasonal activity of stem diameter and the dynamics of growth ring formation were studied using a point dendrometer and micro-coring methods during the 2012 growing season in shrub tamarisk in a desert riparian forest stand in the lower reaches of the Heihe River in Ejin Banner, Inner Mongolia of northwestern China. Generally, the variation in diurnal diameter of tamarisk was characterized by an unstable multi-peak pattern, with the cumulative stem diameter growth over the growing season following an S-shaped curve. The period from late May to early August was the main period of stem diameter growth and growth-ring formation. Among all of the hydroclimatic factors considered in this study, only groundwater depth was significantly correlated with stem diameter increment during this period. Therefore, for the dendrochronological study, the annual rings of the tamarisk can be used to reconstruct processes that determine the regional water regime, such as river runoff and fluctuations in groundwater depth. For the management of desert riparian forests, suitable groundwater depths must be maintained in the spring and summer to sustain tree health and a suitable stand structure. | ShengChun XIAO HongLang XIAO XiaoMei PENG QuanYan TIAN | 2014 | Journal of Arid Land2014，6，4： | 10 |
| 2 | Unraveling a genetic roadmap for improved taste in the domesticated apple显示文摘Although taste is an important aspect of fruit quality, an understanding of its genetic control remains elusive in apple and other fruit crops. In this study, we conducted genomic sequence analysis of 497 Malus accessions and revealed erosion of genetic diversity caused by apple breeding and possible independent domestication events of dessert and cider apples. Signatures of selection for fruit acidity and size, but not for fruit sugar content, were detected during the processes of both domestication and improvement. Furthermore, we found that single mutations in major genes affecting fruit taste, including Ma1, MdTDT, and MdSOT2, dramatically decrease malate, citrate, and sorbitol accumulation, respectively, and correspond to important domestication events. Interestingly, Ma1 was identified to have pleiotropic effects on both organic acid content and sugar:acid ratio, suggesting that it plays a vital role in determining fruit taste. Fruit taste is unlikely to have been negatively affected by linkage drag associated with selection for larger fruit that resulted from the pyramiding of multiple genes with minor effects on fruit size. Collectively, our study provides new insights into the genetic basis of fruit quality and its evolutionary roadmap during apple domestication, pinpointing several candidate genes for genetic manipulation of fruit taste in apple. | Liao Liao Weihan Zhang Bo Zhang Ting Fang Xiao-Fei Wang Yarning Cai Collins Ogutu Lei Gao Gang Chen Xiaoqing Nie Jinsheng Xu Quanyan Zhang Yiran Ren Jianqiang Yu Chukun Wang Cecilia H.Deng Baiquan Ma Beibei Zheng Chun-Xiang You Da-Gang Hu Richard Espley Kui Lin-Wang Jia-Long Yao Andrew C.Allan Awais Khan Schuyler S.Korban Zhangjun Fei Ray Ming Yu-Jin Hao Li Li Yuepeng Han | 2021 | Molecular Plant2021，14，9： | 5 |
| 3 | Genome-Wide Identification, Characterization, and Expression Analysis of Calmodulin-Like Proteins(CMLs) in Apple显示文摘Calcium(Ca^(2+)), a crucial second messenger in plants, is involved in diverse signaling pathways including biotic and abiotic stress responses. However, the functions of most calcium sensors including calcium-dependent protein kinases(CDPKs), calmodulins(Ca Ms), calmodulinlike proteins(CMLs), and calcineurin B-like proteins(CBLs) remain limited in plants, particularly in woody plants. Currently, a total of 83 CMLs and seven Ca Ms were discovered in the apple genome in this study. Functional domain analysis showed that these CMLs and Ca Ms contain a highly conserved EF-hand motif. q RT-PCR assays indicated that these CMLs were expressed ubiquitously in apple, including in the roots, stems,leaves, flowers, and fruits, and also possessed spatial specificity. Finally, most of these CMLs were induced by hormonal and abiotic stress, suggesting their potential roles in the regulation of growth, development, and the stress response in apple. In summary, our findings provide potential evidence that apple CMLs may be involved in abiotic stress and the regulation of plant growth and development. | ZHANG Quanyan LIU Xiaojuan LIU Xin WANG Jiahui YU Jianqiang HU Dagang HAO Yujin | 2017 | Horticultural Plant Journal2017，3，6： | 3 |
| 4 | Stem radial growth indicate the options of species,topography and stand management for artificial forests in the western Loess Plateau, China显示文摘An understanding of the differences in artificial forest between tree species,slope aspects,and management options in arid environments is fundamentally important for efficient management of these artificial systems;however,few studies have quantified the spatial and temporal differences in stem radial growth of trees in the arid western Loess Plateau of China.Using dendrochronology,we assessed the growth of three woody species(the native shrub Reaumuria soongorica,the exotic shrub Tamarix ramosissima and tree Platycladus orientalis)by measuring the annual stem radial increment.We also describe the long-term growth trends and responses to climatic factors on slopes with different aspects during periods with and without irrigation.We found that precipitation during the main growing season was significantly positively correlated with ring growth for all three species and both slope aspects.In addition,supplemental water(e.g.,irrigation,rainwater harvesting)greatly relieved drought stress and promoted radial growth.Our results suggest that as the main afforestation species in the Loess Plateau used for soil and water conservation,P.orientalis is more suitable than T.ramosissima under rain-fed conditions.However,a landscape that combined a tree(P.orientalis)with a shrub(R.soongorica)and grassland appears likely to represent the best means of ecological restoration in the arid western Loess Plateau. | ShengChun Xiao XiaoMei Peng QuanYan Tian Gong Zhu | 2019 | Research in Cold and Arid Regions2019，11，3： | 2 |
| 5 | Interfacial design of silicon/carbon anodes for rechargeable batteries:A review显示文摘Silicon(Si)has been studied as a promising alloying type anode for lithium-ion batteries due to its high specific capacity,low operating potential and abundant resources.Nevertheless,huge volume expansion during alloying/dealloying processes and low electronic conductivity of Si anodes restrict their electrochemical performance.Thus,carbon(C)materials with special physical and chemical properties are applied in Si anodes to effectively solve these problems.This review focuses on current status in the exploration of Si/C anodes,including the lithiation mechanism and solid electrolyte interface formation,various carbon sources in Si/C anodes,such as traditional carbon sources(graphite,pitch,biomass),and novel carbon sources(MXene,graphene,MOFs-derived carbon,graphdiyne,etc.),as well as interfacial bonding modes of Si and C in the Si/C anodes.Finally,we summarize and prospect the selection of carbonaceous materials,structural design and interface control of Si/C anodes,and application of Si/C anodes in all-solid-state lithium-ion batteries and sodium-ion batteries et al.This review will help researchers in the design of novel Si/C anodes for rechargeable batteries. | Quanyan Man Yongling An Chengkai Liu Hengtao Shen Shenglin Xiong Jinkui Feng | 2023 | Journal of Energy Chemistry2023，，1： | 2 |

| 7 | Dynamic games for secure and resilient control system design显示文摘Modern control systems are featured by their hierarchical structure composed of cyber,physical and human layers.The intricate dependencies among multiple layers and units of modern control systems require an integrated framework to address cross-layer design issues related to security and resilience challenges.To this end,game theory provides a bottom-up modeling paradigm to capture the strategic interactions among multiple components of the complex system and enables a holistic view to understand and design cyber-physical-human control systems.In this review,we first provide a multi-layer perspective toward increasingly complex and integrated control systems and then introduce several variants of dynamic games for modeling different layers of control systems.We present game-theoretic methods for understanding the fundamental tradeoffs of robustness,security and resilience and developing a cross-layer approach to enhance the system performance in various adversarial environments.This review also includes three quintessential research problems that represent three research directions where dynamic game approaches can bridge between multiple research areas and make significant contributions to the design of modern control systems.The paper is concluded with a discussion on emerging areas of research that crosscut dynamic games and control systems. | Yunhan Huang Juntao Chen Linan Huang Quanyan Zhu | 2020 | National Science Review2020，7，7： | 2 |
| 8 | Genome-wide identification and expression analyses of homeodomain-leucine zipper family genes reveal their involvement in stress response in apple(Malus×domestica)显示文摘The homeodomain-leucine zipper(HD-Zip)family has been shown to perform amultitude of functions during plant development and stress responses;however,the familymembers and functions have not been identified in apple(Malus×domestica).In this study,83 HD-Zips(MdHDZs)were identified in the apple genome.They were assembled into four subgroups according to the classification in Arabidopsis,where MdHDZs in the same subgroup had similar gene structures and conserved protein motifs.Putative cis-element analysis of MdHDZs promoter regions uncovered numerous elements related to the response of stress and plant hormones.In addition,twelve transcripts of the MdHDZs showed different expression patterns under salt,drought,low temperature and ABA stresses by quantitative reverse transcription-PCR(qRT-PCR)assay.To further explore the function of MdHDZs in apple,MdHDZ3 was selected to verify its function under salt,low temperature and ABA stresses;and genetic transformation was used to obtain MdHDZ3 transgenic apple calli.The results demonstrated that MdHDZ3 increased sensitivity to salt,low temperature and abscisic acid in apple calli,suggesting that MdHDZ3 plays an important role in response to stresses.Subcellular localization and three-dimensional structural analysis revealed that MdHDZ3 was a nuclear-localized protein.Taken together,these findings provide potential information for further identification of HD-Zip proteins in apple. | Quanyan Zhang Tao Chen Xun Wang Jiahui Wang Kaidi Gu Jianqiang Yu Dagang Hu Yujin Hao | 2022 | Horticultural Plant Journal2022，8，3： | 1 |

| 13 | Microcoring and dendrometer-detected intra-annual wood formation of Populus euphratica in the Ejina Oasis,northwestern China显示文摘Seasonal stem radial growth and wood formation of trees have become research hotspots because of their significance for dendroclimatological and dendroecological studies. However, until recently, these studies concentrated on coniferous tree species in high-altitude and high-latitude regions, while detailed information on arid-zone riparian forests is scarce. The main focus of this study is to monitor the intra-annual dynamics of radial growth and tree ring formation in a deciduous species, Populus euphratica. In 2013, we combined the dendrometer and microcoring methods to study this species in the riparian forest of the Ejina Oasis, in arid northwestern China. Vessel enlargement began in early May, and the maximum rate of cell production occurred in early June. The cell division then ceased from early to mid-July. The dendrometer method failed to reliably detect the date of growth initiation and cessation, but succeeded to detect the time of maximum growth rate just like the microcoring method did. We found that weekly stem radial increment data described xylem growth more accurately than daily datasets. Based on correlation analysis among climatic and hydrologic variables, and weekly stem radial increment, weekly ring width increase dataset, the depth to groundwater was the main factor that limited tree ring growth. From a practical perspective, such studies of intra-annual wood formation can provide empirical guidance for seasonal water allocations within a river basin. | XiaoMei Peng ShengChun Xiao GuoDong Cheng QuanYan Tian HongLang Xiao | 2017 | Research in Cold and Arid Regions2017，9，1： | 1 |

| 16 | Processes of runoff in seasonally-frozen ground about a forested catchment of semiarid mountains显示文摘Climate warming increases the variability in runoff of semiarid mountains where seasonally-frozen ground is widely distributed.However,what is not well understood are the processes of runoff,hydrological drivers,and freeze-thaw cycles in seasonally-frozen ground in semiarid mountains.To understand how freeze-thaw cycles affect runoff processes in seasonally-frozen ground,we monitored hydrological processes in a typical headwater catchment with seasonally-frozen ground in Qilian Mountain,China,from 2002 to 2017.We analyzed the responses of runoff to temperature,precipitation,and seasonally-frozen ground to quantify process characteristics and driving factors.The results show that annual runoff was 88.5 mm accounting for 25.6%of rainfall,mainly concentrated in May to October,with baseflow of 36.44 mm.Peak runoff occurred in June,August,and September,i.e.,accounting for spring and summer floods.Runoff during the spring flood was produced by a mix of rainfall,melting snow,and melting seasonally-frozen ground,and had a significant correlation with air temperature.Runoff was mainly due to precipitation accumulation during the summer flood.Air temperature,average soil temperature at 0−50 cm depth,and frozen soil depth variable explained 59.60%of the variation of runoff in the thawing period,while precipitation variable explained 21.9%.Thawing-period runoff and soil temperature had a>0.6 correlation coefficient(P<0.05).In the rainfall-period,runoff was also affected by temperature,soil moisture,and precipitation,which explained 33.6%,34.1%and 18.1%,respectively.Our results show that increasing temperature and precipitation will have an irreversible impact on the hydrological regime in mountainous basins where seasonally-frozen ground is widely distributed. | PengFei Lin ZhiBin He Jun Du LongFei Chen Xi Zhu QuanYan Tian | 2020 | Research in Cold and Arid Regions2020，12，5： | 1 |
| 17 | Meta-Transcriptome Profiling of Novel Invasive Pest Spodoptera frugiperda in Yunnan,China显示文摘Dear Editor,The fall army worm,Spodoptera frugiperda(Lepidoptera:Noctuidae),a highly agricultural destructive pest of cereals,is originally rampant in tropical and subtropical America(Kenis et al.2019).The caterpillars of this moth feed on more than 350 plant species(Harrison et al.2019),including several economically important cultivated grasses such as maize,rice,sorghum and sugarcane,severely threatening the food security(Cock et al.2017).Spodoptera frugiperda is recognized to comprise two morphologically identical but genetically distinct strains with different host range.The'rice strain^R strain,RS)is thought to preferentially feed on rice and various pasture grasses,while the‘com strain,(C strain,CS)on maize,cotton and sorghum(Juarez et al.2012).Unable to tolerate freezing temperature,S.frugiperda is seldom reported outside of America.However,since its first detection in Nigeria in 2016,several congruent reports from African countries about sudden and severe upsurges of S.frugiperda raised the alarm that S.frugiperda is continuously expanding their range to become truly threat(Goergen et al.2016). | Junming Shi Weiwei Li Yunyu Wang Quanyan Chen Fei Deng | 2020 | Virologica Sinica2020，35，2： | 0 |
| 18 | Effect of Predictive Nursing Intervention on Patients with Postpartum Hemorrhage after Cesarean Section显示文摘Objective:To study the effect of predictive nursing intervention on patients with postpartum hemorrhage after cesarean section.Methods:84 delivery women who had been hospitalized for cesarean section from July 2016 to July 2017 were recruited.They were divided into experimental and reference groups by random number table method.Each group had 42 cases.Among them,the reference group adopted the routine nursing mode.On this basis,the experimental group adopted the predictive nursing intervention mode.The amount of postpartum hemorrhage and the causes of bleeding in two groups were compared and analyzed.Results:The volume of postpartum hemorrhage in two hours and 24 hours after operation in the experimental group were lesser compared to reference group.Compared with the reference group,the proportion of postpartum hemorrhage causes,such as incision bleeding,uterine atony bleeding,placental bleeding and vascular rupture bleeding was lower in the experimental group.Besides,the delivery women and family members in the experimental group had higher total satisfaction compared to reference group.The difference between two groups was significance(p<0.05).Conclusion:The results showed that predictive nursing intervention model plays an important role in the nursing of postpartum hemorrhage after cesarean section and should be popularized and applied in clinical practice. | Pu Quanyan | 2018 | Journal of Clinical and Nursing Research2018，2，2： | 0 |
