1Plantations of native shrub species restore soil microbial diversity in the Horqin Sandy Land, northeastern China显示文摘Caragana microphylla Lam., a leguminous shrub species, plays an important role in revegetation in the degraded ecosystems of the Horqin Sandy Land, Northeastern China. Large areas planted with this shrub have been artificially established as sand binders for soil protection, which might change the composition of soil bacterial communities with the development of sand dune stabilization. In this paper, we investigated the diversity and composition of native soil bacterial communities in the C. microphylla plantation for sand fixation using polymerase chain reaction with denaturing gradient gel electrophoresis(PCR-DGGE) to understand the influence of this plantation on sandy soil ecosystem development. We collected soil samples from plantations with an age sequence of 0, 9, 16, and 26 years, as well as from the natural community, to identify the differences among soil bacterial communities. The result showed that bacterial abundance and community composition in the sandy land were affected by the age of the C. microphylla plantation. Moreover, bacterial diversity decreased with increasing plantation age, and the composition of the bacterial community in the 26-year plantation was similar to that in the natural community. Phylogenetic analysis of bands excised from the DGGE gels showed that members of alpha Proteobacterium, gamma Proteobacterium, Gemmatimonadetes and Chloroflexi were dominant in the sandy land. The stabilization of moving sand dune and development of sand-fixed plantation resulted in an increase of soil fertility, which could drive the structural evolvement of soil bacterial community, and it needs over 20 years for the soil bacterial community to form a stable structure, similar to the case for the natural vegetation.DeMing JIANG ChengYou CAO Ying ZHANG ZhenBo CUI XiaoShu HAN 2014Journal of Arid Land2014,6,4:5

3Supramolecular control over LCST behavior of hybrid macrocyclic system based on pillar[5]arene and crown ether显示文摘A hybrid system containing a pillar[5]arene unit and ten crown ether moieties was developed.The LCST behavior and thermo-responsive ness were successfully introduced into this pillar[5]arene-crown ether system.Both host-guest interactions and salting-out effect displayed great effects in realizing the supramolecular control over LCST properties and the rmo-re sponsiveness.Compa red with the individual macrocycles,this hybrid macrocycle system dramatically amplified the supramolecular control effect over LCST behavior.Yan Deng Xing Li Chengyou Han Shengyi Dong 2020Chinese Chemical Letters2020,31,12:0
