1Effects of citrus tree-shape and spraying height of small unmanned aerial vehicle on droplet distribution显示文摘In order to explore the droplet penetration of spraying with unmanned aerial vehicle(UAV)on citrus trees with different shapes,the tests were carried out at different working heights.The material was five years old Cocktail grapefruit(Citrus paradisi cv.Cocktail)grafted on Trafoliata(Poncirus trifoliata L.Raf.)and the type of UAV sprayer used was the 3W-LWS-Q60S.A solution of 300 times Ponceau 2R diluents liquid instead of pesticide was used for citrus fields spraying and the droplets were collected by paper cards.Droplets deposition parameters were extracted and analyzed using digital image processing after scanning the cards.The results showed that:1)For the trees with round head shape canopy,the droplet depositions of the upper,middle and lower layers had a significant difference at 0.05 level.The droplet deposition had the best effect when the working height was 1.0 m,where the average droplet deposition densities were 39.97 droplets/cm2 and the average droplet size was 0.30 mm,but the droplet coverage(3.19%)was lower than that at the working height of 1.5 m(4.27%).2)Under three different working heights of UAV,the tree with open center shape can obtain higher droplet deposition density at all three layers than that with the round head shape canopy.It was especially prominent when the working height was 1.0 m,as the middle layer increased by 49.92%.However,the higher range of droplet deposition density meant larger fluctuation and dispersion.3)The open center shape canopy and the 1.0 m working height obviously improved the droplet coverage rate and droplet density in the citrus plant.For these parameters of open center shape citrus tree,there was no obvious difference in the front and rear direction,but in the left and middle part of the tree crown,the difference reached a 0.05 significant level.Considering droplet deposition characteristics and the spray uniformity,the UAV performed better when working on open center shape plants at a 1.0 m working height.Zhang Pan Deng Lie Lyu Qiang He Shaolan Yi Shilai Liu Yande Yu Yongxu Pan Haiyang 2016International Journal of Agricultural and Biological Engineering2016,9,4:37

3De novo assembly of a Chinese soybean genome显示文摘Soybean was domesticated in China and has become one of the most important oilseed crops. Due to bottlenecks in their introduction and dissemination, soybeans from different geographic areas exhibit extensive genetic diversity. Asia is the largest soybean market; therefore, a high-quality soybean reference genome from this area is critical for soybean research and breeding.Here, we report the de novo assembly and sequence analysis of a Chinese soybean genome for 'Zhonghuang 13' by a combination of SMRT, Hi-C and optical mapping data. The assembled genome size is 1.025 Gb with a contig N50 of 3.46 Mb and a scaffold N50 of 51.87 Mb. Comparisons between this genome and the previously reported reference genome(cv. Williams82) uncovered more than 250,000 structure variations. A total of 52,051 protein coding genes and 36,429 transposable elements were annotated for this genome, and a gene co-expression network including 39,967 genes was also established. This high quality Chinese soybean genome and its sequence analysis will provide valuable information for soybean improvement in the future.Yanting Shen Jing Liu Haiying Geng Jixiang Zhang Yucheng Liu Haikuan Zhang Shilai Xing Jianchang Du Shisong Ma Zhixi Tian 2018Science China(Life Sciences)2018,61,8:11
4Developing superior alleles of yield genes in rice by artificial mutagenesis using the CRISPR/Cas9 system显示文摘Rice yield is an important and complex agronomic trait controlled by multiple genes.In recent decades,dozens of yield-associated genes in rice have been cloned,many of which can increase production in the form of loss or degeneration of function.However,mutations occurring randomly under natural conditions have provided very limited genetic resources for yield increases.In this study,potentially yield-increasing alleles of two genes closely associated with yield were edited artificially.The recently developed CRISPR/Cas9system was used to edit two yield genes:Grain number 1a(Gn1a)and DENSE AND ERECT PANICLE1(DEP1).Several mutants were identified by a target sequence analysis.Phenotypic analysis confirmed one mutant allele of Gn1a and three of DEP1 conferring yield superior to that conferred by other natural high-yield alleles.Our results demonstrate that favorable alleles of the Gnla and DEP1 genes,which are considered key factors in rice yield increases,could be developed by artificial mutagenesis using genome editing technology.Liyu Huang Ru Zhang Guangfu Huang Yanxia Li Getachew Melaku Shilai Zhang Haitao Chen Yanjuan Zhao Jing Zhang Yesheng Zhang Fengyi Hu 2018The Crop Journal2018,6,5:8
5Detection of Huanglongbing(citrus greening) based on hyperspectral image analysis and PCR显示文摘Huanglongbing (HLB, citrus greening) is one of the most serious quarantine diseases of citrus worldwide. To monitor in real-time, recognize diseased trees, and efficiently prevent and control HLB disease in citrus, it is necessary to develop a rapid diagnostic method to detect HLB infected plants without symptoms. This study used Newhall navel orange plants as the research subject, and collected normal color leaf samples and chlorotic leaf samples from a healthy orchard and an HLB-infected orchard, respectively. First, hyperspectral data of the upper and lower leaf surfaces were obtained, and then the polymerase chain reaction (PCR) was used to detect the HLB bacterium in each leaf. The PCR test results showed that all samples from the healthy orchard were negative, and a portion of the samples from the infected orchard were positive. According to these results, the leaf samples from the orchards were divided into disease-free leaves and HLB-positive leaves, and the least squares support vector machine recognition model was established based on the leaf hyperspectral reflectance. The effect on the model of the spectra obtained from the upper and lower leaf surfaces was investigated and different pretreatment methods were compared and analyzed. It was observed that the HLB recognition rate values of the calibration and validation sets based on upper leaf surface spectra under 9-point smoothing pretreatment were 100% and 92.5%, respectively. The recognition rate values based on lower leaf surface spectra under the second-order derivative pretreatment were also 100% and 92.5%, respectively. Both upper and lower leaf surface spectra were available for recognition of HLB-infected leaves, and the HLB PCR-positive leaves could be distinguished from the healthy by the hyperspectral modeling analysis. The results of this study show that early and nondestructive detection of HLBinfected leaves without symptoms is possible, which provides a basis for the hyperspectral diagnosis of citrus with HLB.Kejian WANG Dongmei GUO Yao ZHANG Lie DENG Rangjin XIE Qiang LV Shilai YI Yongqiang ZHENG Yanyan MA Shaolan HE 2019Frontiers of Agricultural Science and Engineering2019,6,2:3
6The tea plant CsLHT1 and CsLHT6 transporters take up amino acids, as a nitrogen source, from the soil of organic tea plantations显示文摘Organic tea is more popular than conventional tea that originates from fertilized plants.Amino acids inorganic soils constitute a substantial pool nitrogen(N)available for plants.However,the amino-acid contents in soils of tea plantations and how tea plants take up these amino acids remain largely unknown.In this study,we show that the amino-acid content in the soil of an organic tea plantation is significantly higher than that of a conventional tea plantation.Glutamate,alanine,valine,and leucine were the most abundant amino acids in the soil of this tea plantation.When 15 N-glutamate was fed to tea plants,it was efficiently absorbed and significantly increased the contents of other amino acids in the roots.We cloned seven CsLHT genes encoding amino-acid transporters and found that the expression of CsLHT1,CsLHT2,and CsLHT6 in the roots significantly increased upon glutamate feeding.Moreover,the expression of CsLHT1 or CsLHT6 in a yeast amino-acid uptake-defective mutant,22Δ10α,enabled growth on media with amino acids constituting the sole N source.Amino-acid uptake assays indicated that CsLHT1 and CsLHT6 are H^(+)-dependent high-and low-affinity amino-acid transporters,respectively.We further demonstrated that CsLHT1 and CsLHT6 are highly expressed in the roots and are localized to the plasma membrane.Moreover,overexpression of CsLHT1 and CsLHT6 in Arabidopsis significantly improved the uptake of exogenously supplied 15 N-glutamate and 15 N-glutamine.Taken together,our findings are consistent with the involvement of CsLHT1 and CsLHT6 in amino-acid uptake from the soil,which is particularly important for tea plants grown inorganic tea plantations.Fang Li Chunxia Dong Tianyuan Yang Shilai Bao Wanping Fang William J.Lucas Zhaoliang Zhang 2021Horticulture Research2021,8,1:3
7Identification of Key Genes for the Ultrahigh Yield of Rice Using Dynamic Cross-tissue Network Analysis显示文摘Significantly increasing crop yield is a major and worldwide challenge for food supply and security.It is well-known that rice cultivated at Taoyuan in Yunnan of China can produce the highest yield worldwide.Yet,the gene regulatory mechanism underpinning this ultrahigh yield has been a mystery.Here,we systematically collected the transcriptome data for seven key tissues at different developmental stages using rice cultivated both at Taoyuan as the case group and at another regular rice planting place Jinghong as the control group.We identified the top 24 candidate high-yield genes with their network modules from these well-designed datasets by developing a novel computational systems biology method,i.e.,dynamic cross-tissue(DCT)network analysis.We used one of the candidate genes,Os SPL4,whose function was previously unknown,for gene editing experimental validation of the high yield,and confirmed that Os SPL4 significantly affects panicle branching and increases the rice yield.This study,which included extensive field phenotyping,cross-tissue systems biology analyses,and functional validation,uncovered the key genes and gene regulatory networks underpinning the ultrahigh yield of rice.The DCT method could be applied to other plant or animal systems if different phenotypes under various environments with the common genome sequences of the examined sample.DCT can be downloaded from http://gffzz188fe103f8f1460asknkfo66b5q5b6qkn.ffgz.tsg.suse.edu.cn/ztpub/DCT.Jihong Hu Tao Zeng Qiongmei Xia Liyu Huang Yesheng Zhang Chuanchao Zhang Yan Zeng Hui Liu Shilai Zhang Guangfu Huang Wenting Wan Yi Ding Fengyi Hu Congdang Yang Luonan Chen Wen Wang 2020Genomics, Proteomics & Bioinformatics2020,18,3:2
8Genome and Comparative Transcriptomics of African Wild Rice Oryza Iongistaminata Provide Insights into Molecular Mechanism of Rhizomatousness and Self-Incompatibility显示文摘Dear Editor, Oryza Iongistaminata is an African wild rice species with AA genome type possessing special traits that are highly valued for improving cultivated rice,such as strong resistance to biotic and abiotic stresses (Song et al.,1995) for improving resistance of cultivars,rhizomatousness for perennial breeding (Glover et al.,2010),and self-incompatibility (SI) for new ways to produce hybrid seeds (Ghesquiere,1986).Deciphering the genome of O.longistaminata will be the key to uncovering the mechanism of these hallmark traits and improving cultivated rice.Yesheng Zhang Shilai Zhang Hui Liu Binying Fu Lijuan Li Min Xie Yue Song Xin Li Jing Cai Wenting Wan Ling Kui Hui Huang Jun Lyu Yang Dong Wensheng Wang Liyu Fluang Jing Zhang Qinzhong Yang Qinfi Shan Qiong Li Wangqi Huang Dayun Tao Muhua Wang Mingsheng Chen Yeisoo Yu Rod A.

9Genomes of 12 fig wasps provide insights into the adaptation of pollinators to fig syconia显示文摘Figs and fig pollinators are one of the few classic textbook examples of obligate pollination mutualism.The specific dependence of fig pollinators on the relatively safe living environment with sufficient food sources in the enclosed fig syconia implies that they are vulnerable to habitat changes.However,there is still no extensive genomic evidence to reveal the evolutionary footprint of this long-term mutually beneficial symbiosis in fig pollinators.In fig syconia,there are also non-pollinator species.The non-pollinator species differ in their evolutionary and life histories from pollinators.We conducted comparative analyses on 11 newly sequenced fig wasp genomes and one previously published genome.The pollinators colonized the figs approximately 66.9 million years ago,consistent with the origin of host figs.Compared with nonpollinators,many more genes in pollinators were subject to relaxed selection.Seven genes were absent in pollinators in response to environmental stress and immune activation.Pollinators had more streamlined gene repertoires in the innate immune system,chemosensory toolbox,and detoxification system.Our results provide genomic evidence for the differentiation between pollinators and nonpollinators.The data suggest that owing to the long-term adaptation to the fig,some genes related to functions no longer required are absent in pollinators.Jinhua Xiao Xianqin Wei Yi Zhou Zhaozhe Xin Yunheng Miao Hongxia Hou Jiaxing Li Dan Zhao Jing Liu Rui Chen Liming Niu Guangchang Ma Wenquan Zhen Shunmin He Jianxia Wang Xunfan Wei Weihao Dou Zhuoxiao Sui Haikuan Zhang Shilai Xing Miao Shi Dawei Huang 2021Journal of Genetics and Genomics2021,48,3:1
10Haem Oxygenase 1 is a potential target for creating etiolated/albino tea plants (Camellia sinensis) with high theanine accumulation显示文摘Theanine content is highly correlated with sensory quality and health benefits of tea infusion.The tender shoots of etiolated and albino tea plants contain higher theanine than the normal green tea plants and are valuable materials for high quality green tea processing.However,why these etiolated or albino tea plants can highly accumulate theanine is largely unknown.In this study,we observed an Arabidopsis etiolated mutant hy1–100(mutation in Haem Oxygenase 1,HO1)that accumulated higher levels of glutamine(an analog of theanine).We therefore identified CsHO1 in tea plants and found CsHO1 is conserved in amino acid sequences and subcellular localization with its homologs in other plants.Importantly,CsHO1 expression in the new shoots was much lower in an etiolated tea plants‘Huangkui’and an albino tea plant‘Huangshan Baicha’than that in normal green tea plants.The expression levels of CsHO1 were negatively correlated with theanine contents in these green,etiolated and albino shoots.Moreover,CsHO1 expression levels in various organs and different time points were also negatively correlated with theanine accumulation.The hy1–100 was hypersensitive to high levels of theanine and accumulated more theanine under theanine feeding,and these phenotypes were rescued by the expression of CsHO1 in this mutant.Transient knockdown CsHO1 expression in the new shoots of tea plant using antisense oligonucleotides(asODN)increased theanine accumulation.Collectively,these results demonstrated CsHO1 negatively regulates theanine accumulation in tea plants,and that low expression CsHO1 likely contributes to the theanine accumulation in etiolated/albino tea plants.Ziping Chen Shijia Lin Tingting Chen Mengxue Han Tianyuan Yang Yan Wang Shilai Bao Zhougao Shen Xiaochun Wan Zhaoliang Zhang 2023Horticulture Research2023,10,2:0
11The ABA synthesis enzyme allele OsNCED2^(T)promotes dryland adaptation in upland rice显示文摘Upland rice shows dryland adaptation in the form of a deeper and denser root system and greater drought resistance than its counterpart,irrigated rice.Our previous study revealed a difference in the frequency of the OsNCED2 gene between upland and irrigated populations.A nonsynonymous mutation(C to T,from irrigated to upland rice)may have led to functional variation fixed by artificial selection,but the exact biological function in dryland adaptation is unclear.In this study,transgenic and association analysis indicated that the domesticated fixed mutation caused functional variation in OsNCED2,increasing ABA levels,root development,and drought tolerance in upland rice under dryland conditions.OsNCED2-overexpressing rice showed increased reactive oxygen species-scavenging abilities and transcription levels of many genes functioning in stress response and development that may regulate root development and drought tolerance.OsNCED2^(T)-NILs showed a denser root system and drought resistance,promoting the yield of rice under dryland conditions.OsNCED2^(T)may confer dryland adaptation in upland rice and may find use in breeding dryland-adapted,water-saving rice.Liyu Huang Yachong Bao Shiwen Qin Min Ning Qinyan Li Qingmao Li Shilai Zhang Guangfu Huang Jing Zhang Wensheng Wang Binying Fu Fengyi Hu 2024The Crop Journal2024,12,1:0
12The C_ν for calculating the shock temperatures of water below 80 GPa显示文摘The shock temperatures of water under 35-50 GPa are firstly measured by the optical pyrometry technique. Cν is a constant below 51 GPa (Cν=7.07R), and increases with the temperature above 51 GPa (Cν=(5.76+3.84×10-4T)R). From our calculation, the dissociation has little effect on Cν. But the electron is essential to the Cν calculation.PENG XiaoJuan LIU FuSheng Zhang ShiLai ZHANG MingJian JING FuQian 2011Science China(Physics,Mechanics & Astronomy)2011,54,8:0
