1Control of Bird Feeding Behavior by Tannin1 through Modulating the Biosynthesis of Polyphenols and Fatty Acid-Derived Volatiles in Sorghum显示文摘Bird predation during seed maturation causes great loss to agricultural production.In this study,through GWAS analysis of a large-scale sorghum germplasm diversity panel,we identified that Tannin1,which encodes a WD40 protein functioning in the WD40/MYB/bHLH complex,controls bird feeding behavior in sorghum.Metabolic profiling analysis showed that a group of sorghum accessions preferred by birds contain mutated tan1-a/b alleles and accumulate significantly lower levels of anthocyanins and condensed tannin compounds.In contrast,a variety of aromatic and fatty acid-derived volatiles accumulate at significantly higher levels in these bird-preference accessions.We subsequently conducted both sparrow feeding and sparrow volatile attractant assays,which confirmed,respectively,the antifeedant and attractant functions of these differentially accumulated metabolites.In addition,the connection between the biosynthesis pathway of anthocyanin and proanthocyanidin and the pathway of fatty acid–derived volatile biosynthesis was demonstrated by discovering that Tannin1 complex modulates fatty acid biosynthesis by regulating the expression of SbGL2 in sorghum,thus affecting the accumulation of fatty acid-derived volatiles.Taken together,our study identified Tannin1 as the gene underlying the major locus controlling bird feeding behavior in sorghum,illustrating an example of the identification of an ecologically impactful molecular mechanism from field observation and providing significant insights into the chemistry of bird–plant ecological interactions.Peng Xie Jiayang Shi Sanyuan Tang Chengxuan Chen Aimal Khan Fengxia Zhang Ying Xiong Chao Li Wei He Guodong Wang Fumin Lei Yaorong Wu Qi Xie 2019Molecular Plant2019,12,10:8
2Long-distance ranging with high precision using a soliton microcomb显示文摘Laser-based light detection and ranging(lidar)plays a significant role in both scientific and industrial areas.However,it is difficult for existing lidars to achieve high speed,high precision,and long distance simultaneously.Here,we demonstrate a high-performance lidar based on a chip-scaled soliton microcomb(SMC)that can realize all three specialties simultaneously.Aided by the excellent properties of ultrahigh repetition rate and the smooth envelope of the SMC,traditional optical frequency comb(OFC)-based dispersive interferometry is heavily improved and the measuring dead zone induced by the mismatch between the repetition rate of the OFC and resolution of the optical spectrum analyzer is totally eliminated.Combined with an auxiliary dual-frequency phase-modulated laser range finder,the none-dead-zone measurable range ambiguity is extended up to 1500 m.The proposed SMC lidar is experimentally implemented in both indoor and outdoor environment.In the outdoor baseline field,real-time,high-speed(up to 35 k Hz)measurement of a long distance of^1179 m is achieved with a minimum Allan deviation of 5.6μm at an average time of 0.2 ms(27 nm at an average time of 1.8 s after high-pass filtering).The present SMC lidar approaches a compact,fast,high-precision,and none-dead zone long-distance ranging system,aimed at emerging applications of frontier basic scientific research and advances in industrial manufacturing.JINDONG WANG ZHIZHOU LU WEIQIANG WANG FUMIN ZHANG JIAWEI CHEN YANG WANG JIHUI ZHENG SAI T.CHU WEI ZHAO BRENT E.LITTLE XINGHUA QU WENFU ZHANG 2020Photonics Research2020,8,12:8

4Ultrasonication-assisted and gram-scale synthesis of Co-LDH nanosheet aggregates for oxygen evolution reaction显示文摘Electrochemical water splitting(EWS)is a highly clean and efficient method for high-purity hydrogen production.Unfortunately,EWS suffers from the sluggish and complex oxygen evolution reaction(OER)kinetics at anode.At present,the efficient,stable,and low-cost non-precious metal based OER electrocatalyst is still a great and long-term challenge for the future industrial application of EWS technology.Herein,we develop a simple and fast approach for gram-scale synthesis of flower-like cobalt-based layered double hydroxides nanosheet aggregates by ultrasonic synthesis,which show outstanding electrocatalytic performance for the oxygen evolution reaction in alkaline media,such as preeminent stability,small overpotential of 300 mV at 10 mA·cm^−2 and small Tafel slope of 110 mV·dec^−1.Tian-Jiao Wang Xiaoyang Liu Ying Li Fumin Li Ziwei Deng Yu Chen 2020Nano Research2020,13,1:5
5Highly pathogenic avian influenza H5N1 Clade 2.3.2.1c virus in migratory birds,2014–2015显示文摘A novel Clade 2.3.2.1c H5N1 reassortant virus caused several outbreaks in wild birds in some regions of China from late 2014 to 2015.Based on the genetic and phylogenetic analyses,the viruses possess a stable gene constellation with a Clade 2.3.2.1c HA,a H9N2-derived PB2 gene and the other six genes of Asian H5N1-origin.The Clade 2.3.2.1c H5N1 reassortants displayed a high genetic relationship to a human H5N1 strain(A/Alberta/01/2014).Further analysis showed that similar viruses have been circulating in wild birds in China,Russia,Dubai(Western Asia),Bulgaria and Romania(Europe),as well as domestic poultry in some regions of Africa.The affected areas include the Central Asian,East Asian-Australasian,West Asian-East African,and Black Sea/Mediterranean flyways.These results show that the novel Clade 2.3.2.1c reassortant viruses are circulating worldwide and may have gained a selective advantage in migratory birds,thus posing a serious threat to wild birds and potentially humans.Yuhai Bi Jianjun Chen Zhenjie Zhang Mingxin Li Tianlong Cai Kirill Sharshov Ivan Susloparov Alexander Shestopalov Gary Wong Yubang He Zhi Xing Jianqing Sun Di Liu Yingxia Liu Lei Liu Wenjun Liu Fumin Lei Weifeng Shi George F.

7An application of the LTP_DSEF model to heavy precipitation forecasts of landfalling tropical cyclones over China in 2018显示文摘Recently, a track-similarity-based Dynamical-Statistical Ensemble Forecast(LTP_DSEF) model has been developed in an attempt to predict heavy rainfall from Landfalling Tropical cyclones(LTCs). In this study, the LTP_DSEF model is applied to predicting heavy precipitation associated with 10 LTCs occurring over China in 2018. The best forecast scheme of the model with optimized parameters is obtained after testing 3452 different schemes for the 10 LTCs. Then, its performance is compared to that of three operational dynamical models. Results show that the LTP_DSEF model has advantages over the three dynamical models in predicting heavy precipitation accumulated after landfall, especially for rainfall amounts greater than 250 mm. The model also provides superior or slightly inferior heavy rainfall forecast performance for individual LTCs compared to the three dynamical models. In particular, the LTP_DSEF model can predict heavy rainfall with valuable threat scores associated with certain LTCs, which is not possible with the three dynamical models. Moreover, the model can reasonably capture the distribution of heavier accumulated rainfall, albeit with widespread coverage compared to observations. The preliminary results suggest that the LTP_DSEF model can provide useful forecast guidance for heavy accumulated rainfall of LTCs despite its limited variables included in the model.Zuo JIA Fumin REN Dalin ZHANG Chenchen DING Mingjen YANG Tian FENG Boyu CHEN Hui YANG 2020Science China Earth Sciences2020,63,1:3
8Incomplete lineage sorting and introgression in the diversification of Chinese spot-billed ducks and mallards显示文摘Incomplete lineage sorting and introgression are 2 major and nonexclusive causes of specieslevel non-monophyly.Distinguishing between these 2 processes is notoriously difficult because they can generate similar genetic signatures.Previous studies have suggested that 2 closely related duck species,the Chinese spot-billed duck Anas zonorhyncha and the mallard A.platyrhynchosvjere polyphyletically intermixed.Here,we utilized a wide geographical sampling,multilocus data and a coalescent-based model to revisit this system.Our study confirms the finding that Chinese spot-billed ducks and Mallards are not monophyletic.There was no apparent interspecific differentiation across loci except those at the mitochondrial DNA(mtDNA)control region and the Z chromosome(CHD1Z).Based on an isolation-with-migration model and the geographical distribution of lineages,we suggest that both introgression and incomplete lineage sorting might contribute to the observed non-monophyly of the 2 closely related duck species.The mtDNA introgression was asymmetric,with high gene flow from Chinese spot-billed ducks to Mallards and negligible gene flow in the opposite direction.Given that the 2 duck species are phenotypically distinctive but weakly genetically differentiated,future work based on genomescale data is necessary to uncover genomic regions that are involved in divergence,and this work may provide further insights into the evolutionary histories of the 2 species and other waterfowls.Wenjuan WANG Yafang WANG Fumin Lei Yang LIU Haitao WANG Jiakuan Chen 2019Current Zoology2019,65,5:2
9Rapid phenotypic evolution with shallow genomic differentiation during early stages of high elevation adaptation in Eurasian Tree Sparrows显示文摘Known as the‘third polar region’,the Qinghai-Tibet Plateau represents one of the harshest highland environments in the world and yet a number of organisms thrive there.Previous studies of birds,animals and humans have focused on well-differentiated populations in later stages of phenotypic divergence.The adaptive processes during the initial phase of highland adaptation remain poorly understood.We studied a human commensal,the Eurasian Tree Sparrow,which has followed human agriculture to the Qinghai-Tibet Plateau.Despite strong phenotypic differentiation at multiple levels,in particular in muscle-related phenotypes,highland and lowland populations show shallow genomic divergence and the colonization event occurred within the past few thousand years.In a one-month acclimation experiment investigating phenotypic plasticity,we exposed adult lowland tree sparrows to a hypoxic environment and did not observe muscle changes.Through population genetic analyses,we identified a signature of polygenic adaptation,whereby shifts in allele frequencies are spread across multiple loci,many of which are associated with muscle-related processes.Our results reveal a case of positive selection in which polygenic adaptation appears to drive rapid phenotypic evolution,shedding light on early stages of adaptive evolution to a novel environment.Yanhua Qu Chunhai Chen Ying Xiong Huishang She Yong E Zhang Yalin Cheng Shane DuBay Dongming Li Per G P Ericson Yan Hao Hongyuan Wang Hongfeng Zhao Gang Song Hailin Zhang Ting Yang Chi Zhang Liping Liang Tianyu Wu Jinyang Zhao Qiang Gao Weiwei Zhai Fumin Lei 2020National Science Review2020,7,1:2
10Positioning taxonomic research for the future显示文摘Why do taxonomists matter? The work of taxonomists is often understated if not completely misunderstood. Without taxonomists, organisms cannot be accurately identified, neither can these organisms be given universally accepted names, and reliably positioned in the phylogenetic tree of life. Thanks to the work of taxonomists over the last 269 years since Carl Linnaeus established the binomial system, we can now measure the health and wealth of our biodiversity in a refined, science-based inventory prescribed by stringent nomenclatural rules.Deyuan Hong Wenying Zhuang Min Zhu Keping Ma Xiaoquan Wang Dawei Huang Yalin Zhang Guodong Ren Wenjun Bu Wanzhi Cai Dong Ren Ding Yang Aiping Liang Fengyan Bai Runzhi Zhang Fumin Lei Shuqiang Li Hongzhi Kong Lei Cai Yucheng Dai Chaodong Zhu Qisen Yang Jun Chen Zhongli Sha Jianping Jiang Jing Che Donghui Wu Jiatang Li Qiang Wang Xinli Wei Ming Bai Xingyue Liu Xuexin Chen Gexia Qiao 2022Zoological Systematics2022,47,3:2

14Taxonomy of the White-browed Shortwing(Brachypteryx montana)complex on mainland Asia and Taiwan:an integrative approach supports recognition of three instead of one species显示文摘Background: The White-browed Shortwing(Brachypteryx montana) is widespread from the central Himalayas to the southeast Chinese mainland and the island of Taiwan, the Philippines and Indonesia. Multiple subspecies are recognised, and several of these have recently been suggested to be treated as separate species based on differences in morphology and songs.Methods: We here analyse plumage, morphometrics, songs, two mitochondrial and two nuclear markers, and geographical distributions of the two mainland Asian taxa B. m. cruralis and B. m. sinensis and the Taiwan Residents B. m. goodfellowi.Results: We conclude that these differ congruently in morphology, songs and DNA. Male B. m. goodfellowi is the most divergent in plumage(sexually monomorphic, unlike the two others; male similar to female), and B. m. cruralis and B. m. sinensis differ in male plumage maturation. The song of B. m. cruralis is strongly divergent from the others, whereas the songs of B. m. sinensis and B. m. goodfellowi are more similar to each other. Brachypteryx m. sinensis and B. m. goodfellowi are sisters, with an estimated divergence time 4.1 million years ago(mya; 95% highest posterior distribution [HPD] 2.8–5.5 mya), and B. m. cruralis separated from these two 5.8 mya(95% HPD 4.1–7.5 mya). We also report notable range extensions of B. m. sinensis as well as sympatry between this taxon and B. m. cruralis in Sichuan Province, China. Brachypteryx m. montana from Java is found to be more closely related to Lesser Shortwing(B. leucophris) and Rusty-bellied Shortwing(B. hyperythra) than to the mainland Asian and Taiwan Residents taxa.Conclusion: Our data support a recent proposal to treat the three mainland Asian and Taiwan Residents taxa as three species, separate from B. montana sensu stricto: B. cruralis(central Himalayas to south central China and south Vietnam), B. sinensis(north central to southeastern part of China's Mainland) and B. goodfellowi(Taiwan Island).Per Alstrom Pamela C.Rasmussen Canwei Xia Magnus Gelang Yang Liu Guoling Chen Min Zhao Yan Hao Chao Zhao Jian Zhao Chengte Yao James A.Eaton Robert Hutchinson Fumin Lei Urban Olsson 2018Avian Research2018,9,4:1

19In situ generation and detection of methyl radical by voltammetry显示文摘In persulfate-acetate, dimethyl sulfoxide or tert-butyl alcohol systems, in situ generation and detection of methyl free radical are realized with voltammetry. It includes the following successive processes. The persulfate S2O82 is polarographically reduced via one-electron addition to sulfate radical SO4, the SO4 initiates chain reaction with acetate, dimethyl sulfoxide, or tert-butyl alcohol on the electrode surface to produce a methyl radical, and one-electron reduction of the methyl radical yields its polarographic reduction wave. In comparison with the known techniques such as ultraviolet radiolysis coupling with electron spin resonance, etc., the proposed method is simple, sensitive and selective.SONG Junfeng CHEN Zhaopeng GUO Wei WANG Fumin 2003Chinese Science Bulletin2003,48,11:1
20Association of plasminogen activator inhibitor-1 4G/5G promoter polymorphism with recurrent cerebral infarction in China’s North Jiangsu Province显示文摘BACKGROUND: Many international studies have shown that plasminogen activator inhibitor-1 (PAI-1) 4G/5G promoter polymorphism does not increase the risk for cerebral infarction. OBJECTIVE: Using PCR methodology and agarose electrophoresis to detect PAI-1 4G/5G promoter polymorphism in patients with recurrent cerebral infarction in the North Jiangsu Province of China, and to compare results with healthy subjects and patients with first-occurrence cerebral infarction in the same region. DESIGN, TIME AND SETTING: Non-randomized, concurrent, control trial. A total of 122 cerebral infarction patients were admitted to Xuzhou Medical College Hospital's Department of Neurology and Xuzhou Central Hospital’s Department of Neurology between July 2003 and August 2006. PARTICIPANTS: The patients consisted of 63 males and 59 females, aged (62 ± 10) years. They were divided into first-occurrence (n = 58) and recurrence (n = 64) groups. In addition, 50 healthy subjects that underwent physical examination in the outpatient department, including 26 males and 24 females, aged (60 ±12) years, were selected as controls. METHODS AND MAIN OUTCOME MEASURES: PAI-1 4G/5G promoter polymorphism was detected and analyzed using PCR methodology and agarose electrophoresis. RESULTS: Significant differences were determined in terms of genotypic frequency and allele frequency of PAI-1 4G/5G promoter polymorphism, in patients with first-occurrence or recurrent cerebral infarction, when compared with healthy subjects (P < 0.05). There was, however, no significant difference between the first-occurrence and recurrence groups (P > 0.05). CONCLUSION: PAI-1 4G/5G promoter polymorphism is genetic risk factor for cerebral infarction in China. However, it may be associated with recurrence of cerebral infarction in patients from the North Jiangsu Province of China.Deqin Geng Jijun Zhu Guofang Chen Xianbi Tang Qiaoyun Yang Jizhen Li Fumin Liu 2008Neural Regeneration Research2008,3,7:1
