| 1 | Volcanism at the Permian-Triassic Boundary in South China and Its Effects on Mass Extinction显示文摘This paper discusses the clayrocks widespread at the Permian-Triassic boundary, which are mostly of volcanic origin. Volcanogenetic textures, structures and minerals such as high-temperature quartz are found in clayrocks at the Permian-Triassic boundary in many places. Thousands of microspherules have been collected from the Boundary clayrocks, many of which exhibit the typical features of the process from melting to cooling and solidification. indicating that they were formed by volcanic eruption or extraterrestrial impact. Volcanic effects on the Permian-Triassic mass extinction may be reflected in conodonts, algae and ammonoids. The Boundary clayrocks are found in many Permian-Triassic sections along the coast of Tethys. Their orighin remains to be studied. | Yin Hongfu, Huang Siji, Zhang Kexin, Yang Fengqing, Ding Meihua, Bi Xianmei and Zhang Suxin China University of Geosciences, Wuhan, Hubei | 1989 | Acta Geologica Sinica(English Edition)1989，63，4： | 22 |
| 2 | A simplified decoding algorithm for multi-CRC polar codes显示文摘Polar codes represent one of the major breakthroughs in 5G standard,and have been proven to be able to achieve the symmetric capacity of binary-input discrete memoryless channels using the successive cancellation list(SCL)decoding algorithm.However,the SCL algorithm suffers from a large amount of memory overhead.This paper proposes an adaptive simplified decoding algorithm for multiple cyclic redundancy check(CRC)polar codes.Simulation results show that the proposed method can reduce the decoding complexity and memory space.It can also acquire the performance gain in the low signal to noise ratio region. | YANG Haifen YAN Suxin ZHANG Hao REN Yan HU Xiangdong LIN Shuisheng | 2020 | Journal of Systems Engineering and Electronics2020，31，1： | 5 |
| 3 | Generation of male-sterile soybean lines with the CRISPR/Cas9 system显示文摘Soybean [Glycine max(L.) Merr.] provides a rich source of plant protein and oil worldwide. The commercial use of transgenic technology in soybean has become a classical example of the application of biotechnology to crop improvement. Although genetically modified soybeans have achieved commercial success,hybrid soybean breeding is also a potential way to increase soybean yield. Soybean cytoplasmic malesterile(CMS) lines have been used in three-line hybrid breeding systems, but their application to exploiting soybean heterosis has been limited by rare germplasm resource of sterile lines. The generation of various genetic diversity male-sterile soybean lines will help to overcome the shortcoming. In this study,we used targeted editing of AMS homologs in soybean by CRISPR/Cas9 technology for the first time to generate stable male-sterile lines. Targeted editing of GmAMS1 resulted in a male-sterile phenotype,while editing of GmAMS2 failed to produce male-sterile lines. GmAMS1 functions not only in the formation of the pollen wall but also in the controlling the degradation of the soybean tapetum.CRISPR/Cas9 technology could be used to rapidly produce stable male-sterile lines, providing new sterile-line materials for soybean hybrid breeding systems. | Xiao Chen Suxin Yang Yaohua Zhang Xiaobin Zhu Xinjing Yang Chunbao Zhang Haiyan Li Xianzhong Feng | 2021 | The Crop Journal2021，9，6： | 3 |
| 4 | Timing of the terrestrial Permian-Triassic boundary biotic crisis:Implications from U-Pb dating of authigenic zircons显示文摘The Late Permian to Early Triassic transition represents one of the most important Phanerozoic mass extinction episodes. The cause of this event is still in debate between catastrophic and gradual mechanisms. This study uses the U-Pb method on zircons from the uppermost Permian/lowermost Triassic clay deposits at Chahe (Guizhou Province, SW China) to examine time constraints for this event. The results of both this and previous studies show that the ages of Bed 68a and 68c (the upper clay bed of the terrestrial Permian-Triassic boundary (PTB)) respectively are 252.6±2.8 and 247.5±2.8 Ma. This age (within the margin of error) almost accords with the upper clay bed (Bed 28) age of Meishan and the eruption age of Tunguss Basalt, and is so far the most accurate age obtained from terrestrial PTB. The claystone of Bed 68 was formed in the earliest Triassic. The biotic crisis occurred at nearly the same time in terrestrial and marine environments during Permian-Triassic interval; however the extinction patterns and processes are different. The extinction pattern of the terrestrial plants shows a major decline at the PTB after long-term evolution, followed by a retarded extinction of the relicts in the earliest Triassic. | YU JianXin LI HuiMin ZHANG SuXin YANG FengQing FENG QingLai | 2008 | Science China Earth Sciences2008，51，11： | 2 |
| 5 | The miR166 mediated regulatory module controls plant height by regulating gibberellic acid biosynthesis and catabolism in soybean显示文摘MicroRNAs(miRNAs)are endogenous small noncoding RNAs that play critical roles in regulating plant growth and development.Here,we used Short Tandem Target Mimic(STTM)technology to generate soybean(Glycine max(L.)Merr.)miRNA knockdown lines and identify miRNAs that regulate plant height,a key agronomic trait that affects yield.STTM166 successfully silenced miR166 in soybean and upregulated the expression of miR166 target genes,such as ATHB14-LIKE.The miR166 knockdown lines(GmSTTM166)displayed a reduced plant height phenotype.Moreover,GmSTTM166 plants contained lower levels of bioactive gibberellic acid(GA3)than wild-type plants,and application of exogenous GA partially rescued the dwarf phenotype of GmSTTM166.Knockdown of miR166 altered the expression of genes involved in GA biosynthesis and catabolism.Further analysis revealed that ATHB14-LIKE directly represses transcription of the GA biosynthesis genes Gm GA1 and Gm GA2,while activating transcription of the GA catabolic gene GIBBERLLIN 2 OXIDASE2(GmGA2ox2).Collectively,these results reveal a pivotal role for miR166 in the genetic control of plant height in soybean,thereby providing invaluable insights for molecular breeding to improve soybean yield. | Chen Zhao Jingjing Ma Yaohua Zhang Suxin Yang Xianzhong Feng Jun Yan | 2022 | Journal of Integrative Plant Biology2022，64，5： | 1 |

| 8 | Combining magnetocaloric and elastocaloric effects in a Ni45Co5Mn37In13 alloy显示文摘1.Introduction Refrigeration plays an essential role in nowadays society.However,conventional refrigeration based on vapor compression cooling shows high energy consumption,complicated structure and even environmental pollution.Searching for an environmentalfriendly and energy-saving refrigeration technology has become a matter of concern[1,2].In the past few decades,the solid-state refrigeration technologies mainly represented by magnetocaloric effect(MCE),electrocaloric effect(ECE)and elastocaloric effect(e CE)have been regarded as promising candidate to replace traditional vapor compression refrigeration technology owing to environmental friendliness and high efficiency[1-9]. | Pengtao Cheng Zhenjia Zhou Jiaxing Chen Zongbin Li Bo Yang Kun Xu Zhe Li Jun Li Zhengming Zhang Dunhui Wang Suxin Qian Youwei Du | 2021 | Journal of Materials Science & Technology2021，，35： | 0 |
| 9 | Drought-triggered repression of miR166 promotes drought tolerance in soybean显示文摘Drought stress limits agricultural productivity worldwide.Identifying and characterizing genetic components of drought stress-tolerance networks may improve crop resistance to drought stress.We show that the regulatory module formed by miR166 and its target gene,ATHB14-LIKE,functions in the regulation of drought tolerance in soybean(Glycine max).Drought stress represses the accumulation of miR166,leading to upregulation of its target genes.Optimal knockdown of miR166 in the stable transgenic line GmSTTM166 conferred drought tolerance without affecting yield.Expression of ABA signaling pathway genes was regulated by the miR166-mediated regulatory pathway,and ATHB14-LIKE directly activates some of these genes.There is a feedback regulation between ATHB14-LIKE and MIR166 genes,and ATHB14-LIKE inhibits MIR166 expression.These findings reveal that drought-triggered regulation of the miR166-mediated regulatory pathway increases plants drought resistance,providing new insights into drought stress regulatory network in soybean. | Chen Zhao Jingjing Ma Chen Yan Yu Jiang Yaohua Zhang Yudan Lu Ye Zhang Suxin Yang Xianzhong Feng Jun Yan | 2024 | The Crop Journal2024，12，1： | 0 |
