2Synthesis and fluorescence properties of a 1,3-disubstituted thiacalix[4]arene crown-5 armed with phenothiazine moieties显示文摘A new thiacalix[4]arene phenothiazine derivative(2) based on a thiacalix[4]crown with a 1,3-alternate conformation has been synthesized and characterized. In THF-water mixture, Compound 2 exhibits a strong fluorescence emission, with a large Stokes shift(λex/em = 357 nm/505 nm, Δλ = 148 nm), which helps to avoid interference in excitation and emission. For the metal ions tested, the fluorescence of Compound 2 was quenched only by Fe3+ and Cr3+ ions. Evidence for the hydrolysis reaction promoted by the metal ions is given by X-ray crystallography, mass spectra(MS), infrared(IR) spectra, and fluorescence spectroscopy data.Qiang Sun Lan Mu Xi Zeng Jianglin Zhao Takehiko Yamato Jianxin Zhang 2015Science China Chemistry2015,58,3:1
3Identification of S-genotypes and a novel S-RNase in 84 native Chinese pear accessions显示文摘The Chinese pear(Pyrus spp.)exhibits typical gametophytic self-incompatibility(GSI),which inhibits self-crossing and promotes outcrossing,similar to other fruit species in the Rosaceae family.Thus,S-compatible cultivars are required in pear orchards to ensure successful pollination and stable yields.In this study,84 native Chinese pear accessions were genotyped by allele-specific PCR using one pair allele consensus primers and 29 pairs of S-allele-specific primers that were designed in this study.After cloning and sequencing the PCR products,the S-genotypes of all 84 pear accessions,including wild and cultivated accessions,were determined.The reported 34 S-alleles and a novel S-allele were isolated from these pear accessions.These S-alleles were expressed specifically in the style.Sequence analysis identified that six pear cultivars originated in China shared the same S-RNases with P.communis(Pc).These findings supported the hypothesis that oriental and occidental Pyrus spp.may share the same pool of alleles at the S-locus.A novel S-RNase was isolated in ‘Putiandouli’,‘Daguoshanli’,‘Yunhongli1,and‘Dianli’and deposited as S67-RNase under accession number MT773568.Furthermore,the deduced amino acid sequences exhibited high similarity(99.56%)to S32-RNase in Malus.The high similarity between S-RNase in Pyrus and Malus indicated that the existence of S-RNase could have predated speciation between Pyrus and Malus.Furthermore,S-allele information was rearranged in Asian and European pears to provide information for selecting the best pollinator for widely cultivated pear cultivars in China.This information is useful for pear production,cross-breeding,and understanding the mechanism of the self-incompatibility reaction.Min He Lufei Li Ying Xu Jianxin Mu Zhihua Xie Chao Gu Shaoling Zhang 2022Horticultural Plant Journal2022,8,6:1

5High-precision measurements of the inter-annual evolution for Urumqi Glacier No.1 in eastern Tien Shan,China显示文摘High-precision measuring of glacier evolution remains a challenge as the available global and regional remote sensing techniques cannot satisfactorily capture the local-scale processes of most small-and medium-sized mountain glaciers.In this study,we use a high-precision local remote sensing technique,long-range terrestrial laser scanning(TLS),to measure the evolution of Urumqi Glacier No.1 at an annual scale.We found that the dense point clouds derived from the TLS survey can be used to reconstruct glacier surface terrain,with certain details,such as depressions,debris-covered areas,and supra-glacial drainages can be distinguished.The glacier experienced pronounced thickness thinning and continuous retreat over the last four mass-balance years(2015−2019).The mean surface slope of Urumqi Glacier No.1 gradually steepened,which may increase the removal of glacier mass.The glacier was deeply incised by two very prominent primary supra-glacial rivers,and those rivers presented a widening trend.Extensive networks of supra-glacial channels had a significant impact on accelerated glacier mass loss.High-precision measuring is of vital importance to understanding the annual evolution of this type of glacier.ChunHai Xu ZhongQin Li JianXin Mu PuYu Wang FeiTeng Wang 2021Research in Cold and Arid Regions2021,13,6:0
6Effect of topography on the changes of Urumqi Glacier No.1 in the Chinese Tianshan Mountains显示文摘Topography plays an important role in determining the glacier changes.However,topography has often been oversimplified in the studies of the glacier changes.No systematic studies have been conducted to evaluate the relationship between the glacier changes and topographic features.The present study provided a detailed insight into the changes in the two branches(east branch and west branch)of Urumqi Glacier No.1 in the Chinese Tianshan Mountains since 1993 and systematically discussed the effect of topography on the glacier parameters.This study analyzed comprehensive recently observed data(from 1992/1993 to 2018/2019),including mass balance,ice thickness,surface elevation,ice velocity,terminus,and area,and then determined the differences in the changes of the two branches and explored the effect of topography on the glacier changes.We also applied a topographic solar radiation model to analyze the influence of topography on the incoming shortwave radiation(SW_(in))across the entire glacier,focusing on the difference in the SW_(in) between the two branches.The glacier mass balance of the east branch was more negative than that of the west branch from 1992/1993 to 2018/2019,and this was mainly attributed to the lower average altitude of the east branch.Compared with the west branch,the decrease rate of the ice velocity was lower in the east branch owing to its relatively increased slope.The narrow shape of the west branch and its southeast aspect in the earlier period resulted in a larger glacier terminus retreat of the west branch.The spatial variability of the SW_(in) across the glacier surface became much larger as altitude increased.The SW_(in) received by the east branch was slightly larger than that received by the west branch,and the northern aspect could receive more SW_(in),leading to glacier melting.In the future,the difference of the glacier changes between the two branches will continue to exist due to their topographic differences.This work is fundamental to understanding how topographic features affect the glacier changes,and provides information for building different types of relationship between the glacier area and ice volume to promote further studies on the basin-scale glacier classification.LI Hongliang WANG Puyu LI Zhongqin JIN Shuang XU Chunhai MU Jianxin HE Jie YU Fengchen 2022Journal of Arid Land2022,14,7:0
