| 1 | Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light. | lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu | 2017 | Science Bulletin2017，62，21： | 6 |
| 2 | Comparative transcriptome analysis of different nitrogen responses in low-nitrogen sensitive and tolerant maize genotypes显示文摘Although previous researches have greatly increased our general knowledge on plant responses to nitrogen(N)stress,a comprehensive understanding of the different responses in crop genotypes is still needed.This study evaluated 304 maize accessions for low-N tolerance under field conditions,and selected the low-N sensitive Ye478 and low-N tolerant Qi319 for further investigations.After a 5-day low-N treatment,the typical N-deficient phenotype with yellowing older leaves was observed in Ye478 but not in Qi319.After the 5-day low-N stress,16 RNA libraries from leaf and root of Ye478 and Qi319 were generated.The differentially expressed genes(DEGs)in the root of Qi319 up-regulated by special N deficiency were mainly enriched in energy-related metabolic pathways,including tricarboxylic acid metabolic process and nicotinamide metabolic process.Consistent with yellowing older leaves only observed in Ye478,the special N deficiency-responsive DEGs related to thylakoid,chloroplast,photosynthetic membrane,and chloroplast stroma pathways were repressed by low-N stress in Ye478.A total of 216 transcription factors(TFs),including ZmNLP5,were identified as special N deficiencyresponsive TFs between Qi319 and Ye478,indicating the importance of transcriptional regulation of N stress-responsive pathway in different tolerance to low-N stress between crop genotypes.In addition,15 miRNAs were identified as DEGs between Qi319 and Ye478.Taken together,this study contributes to the understanding of the genetic variations and molecular basis of low-N tolerance in maize. | DU Qing-guo YANG Juan Shah Syed Muhammad Sadiq YANG Rong-xin YU Jing-juan LI Wen-xue | 2021 | Journal of Integrative Agriculture2021，20，8： | 5 |
