| 1 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019，12，3： | 15 |
| 2 | Activation of Mitochondrial orf355 Gene Expression by a Nuclear-Encoded DREB Transcription Factor Causes Cytoplasmic Male Sterility in Maize显示文摘Coordination between mitochondria and the nucleus is crucial for fertility determination in plants with cytoplasmic male sterility(CMS).Using yeast one-hybrid screening,we identified a transcription factor,ZmDREB1.7,that is highly expressed in sterile microspores at the large vacuole stage and activates the expression of mitochondria-encoded CMS gene orf355.Δpro,a weak allele of ZmDREB1.7 with the loss of a key unfolded protein response(UPR)motif in the promoter,partially restores male fertility of CMS-S maize.ZmDREB1.7 expression increases rapidly in response to antimycin A treatment,but this response is attenuated in theΔpro allele.Furthermore,we found that expression of orf355 in mitochondria activates mitochondrial retrograde signaling,which in turn induces ZmDREB1.7 expression.Taken together,these findings demonstrate that positive-feedback transcriptional regulation between a nuclear regulator and a mitochondrial CMS gene determines male sterility in maize,providing new insights into nucleus-mitochondria communication in plants. | Senlin Xiao Jie Zang Yuanrong Pei Jie Liu Juan Liu Wei Song Zi Shi Aiguo Su Jiuran Zhao Huabang Chen | 2020 | Molecular Plant2020，13，9： | 10 |
| 3 | Human bronchial epithelial cell injuries induced by fine particulate matter from sandstorm and non-sandstorm periods:Association with particle constituents显示文摘Epidemiological studies have demonstrated the exacerbation of respiratory diseases following sandstorm-derived particulate matter(PM) exposure.The presence of anthropogenic and biological agents on the sandstorm PM and the escalation of PM < 2.5 μm(PM2.5)pollution in China have led to serious concerns regarding the health effects of PM2.5during Asian sandstorms.We investigated how changes in PM2.5composition,as the weather transitioned towards a sandstorm,affected human airway epithelial cells.Six PM2.5samples covering two sandstorm events and their respective background and transition periods were collected in Baotou,an industrial city near the Gobi Desert in China.PM samples from all three periods had mild cytotoxicity in human bronchial epithelial cell line BEAS-2B,which was positively correlated with the contents of polycyclic aromatic hydrocarbons and several metals.All PM samples potently increased the release of interleukin-6(IL-6) and interleukin-8(IL-8).Endotoxin in all samples contributed significantly to the IL-6 response,with only a minor effect on IL-8.Cr was positively correlated with both IL-6 and IL-8 release,while Si was only associated with the increase of IL-6.Our study suggests that local agricultural and industrial surroundings in addition to the sandstorm play important roles in the respiratory effects of sandstorm-derived PM. | Bin Wang Ning Li Furong Deng Nicholas Buglak George Park Shu Su Aiguo Ren Guofeng Shen Shu Tao Xinbiao Guo | 2016 | Journal of Environmental Sciences2016，28，9： | 9 |
| 4 | Longitudinal distributions of two formation pathways of biogenic gases in continental deposits: A case study from Sebei 1 gas field in the Qaidam Basin, western China显示文摘The distribution of two formation pathways of biogenic methane, acetate fermentation and reduction of CO2, has been extensively studied. In general, CO2 reduction is the dominate pathway in marine envi- ronment where acetate is relatively depleted because of SRB consuming. While in terrestrial freshwater or brackish environment, acetate fermentation is initially significant, but decreases with increasing buried depth. In this paper, character of biogenic gases is profiled in the XS3-4 well of the Sebei 1 gas field in the Sanhu depression, Qaidam Basin. It indicates that those two pathways do not change strictly with increasing buried depth. CO2 reduction is important near the surface (between 50 m and 160 m), and at the mesozone (between 400 and 1650 m). While acetate fermentation is the primary pathway at two zones, from 160 to 400 m and from 1650 to 1700 m. δ 13C of methane generated in those two acetate fermentation zones varies greatly, owing to different sediment circumstances. At the sec- ond zone (160-400 m), δ 13C1 ranges from ?65‰ to ?30‰ (PDB), because the main deposit is mudstone and makes the circumstance confined. At the fourth zone of the well bottom (1650-1700 m), δ 13C1 is lighter than ?65‰ (PDB). Because the deposit is mainly composed of siltstone, it well connects with outer fertile groundwater and abundant nutrition has supplied into this open system. The high con- centration of acetate is a forceful proof. δ 13C of methane would not turn heavier during fermentation, owing to enough nutrition supply. In spite of multi-occurrence of acetate fermentation, the commercial gas accumulation is dominated by methane of CO2-reduction pathway. A certain content of alkene gases in the biogenic gases suggests that methanogensis is still active at present. | SHUAI YanHua ZHANG ShuiChang ZHAO WenZhi SU AiGuo WANG HuiTong | 2007 | Science China Earth Sciences2007，50，2： | 5 |
| 5 | Geochemical evidence for strong ongoing methanogenesis in Sanhu region of Qaidam Basin显示文摘Sanhu depression of Qaidam Basin is the largest biogenic gas production region in China.Headspace samples were collected from two wells in this region,and hydrogen and propylene compounds were detected in these samples with a certain concentration.The stable hydrogen isotope ratio of H 2 is relatively light (-700‰--820‰).The stable carbon isotope ratio of propylene ranges from -27‰ to -40‰,which coincides with the rule of change of the stable carbon isotope of kerogen at the corresponding horizon.The characteristic analysis of sediments,structures,and Ar and He components in the region indicates that these microelement compounds are the product of degradation of organic substances by microorganisms,rather than from the mantle source,inorganic reaction or other sources.Detection of these components provides solid evidence for the strong ongoing methanogenesis in this region. | YanHua Shuai ShuiChang Zhang AiGuo Su HuiTong Wang BaoYuan Cai Hui Wang | 2010 | Science China Earth Sciences2010，53，1： | 5 |
| 6 | Identification of a locus associated with genic male sterility in maize via EMS mutagenesis and bulked-segregant RNA-seq显示文摘Genic male sterility(GMS) is one of the most important resources for exploiting heterosis in crop breeding, so that identifying genomic loci regulating GMS is desirable. However, many regulatory genes controlling GMS have not yet been characterized in maize, owing partly to a lack of genetic materials. We generated a recessive male-sterile maize mutant in the Jing 724 genetic background via ethyl methanesulfonate treatment, and found the male sterility to be due to a single gene mutation. Bulk-segregant RNA sequencing of three replicates indicated that one genomic region located at the end of chromosome 4 was associated with the observed mutant phenotype. Among genes with nonsynonymous mutations,Zm00001 d053895(bHLH51) showed abolished expression in the sterile bulks and was annotated as a bHLH transcription factor orthologous to Arabidopsis AMS, suggesting an association with the male sterility of the mutant. Kompetitive Allele-Specific PCR assays further validated the exclusive correlation of male sterility with the single C-to-T mutation in the fifth exon. The new maize mutant and the potential SNP locus provide novel genetic material for investigating the molecular mechanism underlying tapetal development and may facilitate the improvement of hybrid production systems. | Zi Shi Wen Ren Yanxin Zhao Xiaqing Wang Ruyang Zhang Aiguo Su Shuai Wang Chunhui Li Jiarong Wang Shuaishuai Wang Yunxia Zhang Yulong Ji Wei Song Jiuran Zhao | 2021 | The Crop Journal2021，9，6： | 4 |

| 8 | Biogas charging and dissipating process and its accumulation in the Sebei gasfield,Qaidam Basin,China显示文摘The Sebei gasfield is the largest biogas accumulation found in China and many reservoirs and seal rocks superposed on a syndepositional anticline in Quaternary.The biogas charging and dissipating process and its distribution have been a research focus for many years.The authors suggest a diffusing and accumulating model for the biogas,as they find that the shallower the gas producer,the more methane in the biogas,and the lighter stable carbon isotope composition of methane.Based on the diffusing model,diffused biogas is quantitatively estimated for each potential sandy reservoir in the gasfield,and the gas charging quantity for the sandy reservoir is also calculated by the diffused gas quantity plus gas reserve in-place.A ratio of diffusing quantity to charging quantity is postulated to describe biogas accumulating state in a sandy reservoir,if the ratio is less than 0.6,the reservoir forms a good gas-pool and high-production layer in the gasfield,which often occurs in the reservoirs deeper than 900 m;if the ratio is greater than 0.6,a few gas accumulated in the reservoir,which frequently exists in the reservoirs shallower than 900 m.Therefore,a biogas accumulation model is built up as lateral direct charging from gas source for the sands deeper than 900 m and indirect charging from lower gas-bearing sands by diffusion at depth shallower than 900 m.With this charging and diffusion quantitative model,the authors conducted re-evaluation on each wildcat in the central area of the Qaidam Basin,and found many commercial biogas layers. | JIN Qiang 1,CHENG FuQi 1,2 ,SU AiGuo 3 ,ZHU GuangYou 3 ,WANG Li 1 &CAO Qian 1 1 China University of Petroleum,Dongying,Shandong 257061,China 2 Geological Institute of Shengli Oilfield,SINOPEC,Dongying,Shandong 257015,China 3 Petroleum Exploration and Development Institute,PetroChina,Beijing 100083,China | 2008 | Science China Earth Sciences2008，51，S1： | 2 |
| 9 | Source of nutrient substrates for microbes in deep biosphere and characteristics of biogenic gas source rock显示文摘To understand the biogas formation in geological basins, the present work investigated the reactive organic matter in sediments of the Sanhu depression of Qaidam Basin, a prolific region of biogenic gases with a proved reserve of 300 bil steres. The ROC (reactive organic carbon) was obtained by ultrasonic extraction from sediment samples in the solution of 6 mol/L HCl and 5% K2SO4. To investigate the effect of early diagenesis, parts of the samples were heated at 80°C before extraction. The results showed that the ROC content at a constant temperature decreased with increasing burial depths, which should be attributed to the microbial consumption. For the same sample, the ROC content heated at 80°C was dramatically higher than the unheated. The increment of the ROC content for some samples was as high as 200% in the experiment. The dramatically increasing ROC by thermal action should be the major nutrient substrate for the deep biospheres in most geological basins. There is a positive correlation between the reactive organic carbon (ROC) and the traditional insoluble organic carbon (TOC), not only for its absolute content of the ROC, but also for the 'ROC' produced in thermal action, all of these are clearly related with TOC. These data showed that higher abundance of organic matter can contribute more to the reactive organic matter, and is more favorable to the formation of biogenic gases. In the Sanhu depression of Qaidam Basin, more than 85% of the biogenic gas reserves occur in the lower layers (K5-K13) with a relatively high abundance of organic matter. The exploration has provided further evidence that deposits with higher abundance of organic matter are effective biogas source rocks. | SHUAI YanHua ZHANG ShuiChang CHEN JianPing SU AiGuo | 2010 | Science China Earth Sciences2010，53，8： | 2 |
