| 1 | Characterization of small RNAs from Ulva prolifera by high-throughput sequencing and bioinformatics analysis显示文摘The seaweed Ulva prolifera exists in 2 different states; attached to rocks or free-floating. However, there is little difference between the structures of the 2 states. U. prolifera thalli show significant differences in growth rate, with the attached thalli growing at a normal rate and free-floating thalli growing at a much faster rate. This raised the possibility that the growth of the two states may be regulated differently. miRNAs are important post-transcriptional regulators. In higher plants and animals, miRNAs have been extensively studied but they have been rarely studied in algae. To identify U. prolifera miRNAs and to investigate their possible roles in proliferation, we constructed and sequenced small RNA (sRNA) libraries from U. prolifera. Our results show that U. prolifera has a complex small RNA system that might play important roles in various processes. | HUANG AiYou WANG GuangCe HE LinWen NIU JianFeng ZHANG BaoYu | 2011 | Chinese Science Bulletin2011，56，27： | 3 |
| 2 | Identification and bioinformatics analysis of pseudogenes from whole genome sequence of Phaeodactylum tricornutum显示文摘Pseudogenes share sequence similarities with functional genes,but in general they have lost their protein-coding ability.The identification of pseudogenes is a very important step in genome annotation.Phaeodactylum tricornutum is a marine diatom that is rich in polyunsaturated fatty acids(PUFAs).The genome of P.tricornutum has been completely sequenced.To identify pseudogenes in P.tricornutum,we developed a pipeline to discover and characterize pseudogenes.We identified a total of 1654 'true' processed pseudogenes,714 duplicated pseudogenes and 4729 pseudogene fragments.The results of the bioinformatics analysis indicated that the genome sequence of P.tricornutum contained many pseudogenes and pseudogene fragments. | JI ChangMian HUANG AiYou LIU WenLing PAN GuangHua WANG GuangCe | 2013 | Chinese Science Bulletin2013，58，9： | 2 |

| 9 | Distorted aryl homochirality controlled byβ-sheet folding显示文摘Distortion of planar aromatics occurs in the fused rings conjugated with bulky substituents,which generates racemic enantiomers with high transformation energy barriers.However,direct synthesis of homochiral distorted aryl compounds is a very challenging task.Here,we presented a molecular folding strategy to control distorted aryl homochirality.Amino acids and their derivatives conjugated on the polycyclic aromatic hydrocarbons including benzenes,naphthalenes and triphenylenes,which formed parallelβ-sheet arrays through intramolecular hydrogen bonds.The folding behavior enabled distorted or twisted geometry of aromatics,of which the handedness was associated with the absolute chirality of amino acids.X-ray crystallography,theoretical calculations and circular dichroism spectroscopy verified the distorted homochirality in the solid and solution phase.The relatively small rotational barrier between the enantiomers made the molecule sensitive to the environment and thus realized the solvent-controlled chiral inversion.Theβ-sheet folding strategy can be widely used in polycyclic aromatic hydrocarbons with various functions,which provided a promising strategy to control inherent chirality of aromatics with adaptive chiroptical responses. | Yunying Xu Aiyou Hao Pengyao Xing | 2023 | Chinese Chemical Letters2023，34，11： | 0 |
| 10 | Metabolomic and proteomic responses of Phaeodactylum tricornutum to hypoxia显示文摘Diatoms are important contributors to global net primary productivity,and play a crucial role in the biogeochemical cycles of carbon,phosphorus,nitrogen,iron,and silicon.Currently in some regions in the ocean,there’s a trend that carbon content is high while oxygen concentration is low,and the underlying mechanisms of diatoms’response to low oxygen environments are worth investigating.Phaeodactylum tricornutum is a model diatom whose genome has been sequenced;it provides a universal molecular toolbox and a stable transgenic expression system.Therefore,the study of the responses of P.tricornutum to low oxygen has not only fundamental research significance but also important ecologic al significance.In this study,growth rates were determined and proteomic analysis and metabolomic analysis were performed to examine P.tricornutum responses under different oxygen concentrations(2%oxygen concentration for hypoxic condition and 21%oxygen concentration for the normal condition(sterilized air)).Results show that the hypoxic environment inhibited the growth of P.tricornutum.In the hypoxic conditions,P.tricornutum could reset its metabolism pathways,including enhancement in lipid utilization,replenishment of tricarboxylic acid(TCA)cycle through the glyoxylic acid cycle,and down-regulation of photorespiration to reduce energy waste.Additionally,the stress resistance mechanism was activated to facilitate the adaptation to low oxygen conditions.This study helps to reveal the different metabolic changes to hypoxia of diatom from that of higher plants,which might be ascribed to their different habitats and needs further exploration in the future. | Peipei ZHAO Qinghua WU Xuekui XIA Shiyi GUO Sizhong SHEN Yujue WANG Aiyou HUANG | 2022 | Journal of Oceanology and Limnology2022，40，5： | 0 |
| 11 | Helical secondary structures and supramolecular tilted chirality in N-terminal aryl amino acids with diversified optical activities显示文摘Helix structures at atomic/molecular level have not been found in self-assembled peptide seque nce with less than three residues.Asβ-sheet supramolecular secondary structures have been discovered in solidstate amino acids,we here report the conjugation of simple N-terminal aryl protecting group could give rise to helical supramolecular secondary structures in solid-state,which determines the optical activities of the adjacent aryl groups.The carboxylic acid-involved asymmetric H-bonds in N-te rminal aryl amino acids induce the emergence of super-helical structures of amino acid residues and aryl groups.In most cases,supramolecular tilted chirality of aryl groups is opposite to that of amino acid sequences,of which handedness and helical pitch are determined by the H-bond modalities.Determining correlation between supramolecular tilted chirality of aryl segments and their chiroptical activities is firstly unveiled,which was verified by the computational results based on density functional theory.Most aryl amino acids self-assembled by nanoprecipitation method via crystallization induced self-assembly into rigid one-dimensional microstructures with ultra-high Young's modulus.This study reveals the generic existence of chiral supramolecular structure s in aggregated amino acid derivatives and gives an in-depth investigation into the structural-property relationships,which could guide the rational design and screening of chiroptical supramolecular materials. | Zhuoer Wang Aiyou Hao Pengyao Xing | 2021 | Chinese Chemical Letters2021，32，4： | 0 |
| 12 | Gas phase ethylene polymerization over SiO_(2)-supported organosilyl chromate UCC S-2 catalyst using a high-speed stirred-autoclave reactor显示文摘Although an important industrial catalyst for producing high density polyethylene,the SiO_(2)-supported organosilyl chromate UCC S-2 catalyst has not been fully investigated compared with the SiO_(2)-supported oxo chromium Phillips catalyst.In this work,gas phase ethylene polymerization by S-2 catalysts(Cat-1,Cat-2,and Cat-3)was carried out in a high-speed stirredautoclave reactor.The effects of temperature,time,and pressure on kinetics,activity,and product properties were studied.All kinetics were typical built-up types with slow decay.Compared to the simple physical mixtures of Cat-1 and Cat-2,Cat-3 showed higher activity and its product had a broader molecular weight distribution,indicating new active species induced during blending of Cat-1 and Cat-2 in n-hexane.The innovation by a simple catalyst technology created a new application to meet market demands. | Liuzhong LI Aiyou HAO Ruihua CHENG Boping LIU | 2011 | Frontiers of Chemical Science and Engineering2011，5，1： | 0 |
| 13 | Fmoc-protected amino acids as luminescent and circularly polarized luminescence materials based on charge transfer interaction显示文摘Fluorenylmethyloxycarbonyl(Fmoc)-protected amino acids are effective building blocks in self-assembled architectures at hierarchical levels,which however show limited luminescent properties and chiroptical activities.Here we introduce a charge-transfer strategy to build two-component luminescent materials with emerged circularly polarized luminescence properties.A library of Fmoc-amino acids was built,which selectively form charge-transfer complexes with the electron-deficient acceptor.Embedding in amorphous polymer matrix or physical grinding could trigger the charge-transfer luminescence with adjusted wavelengths in a general manner.X-ray diffraction results suggest the multiple binding modes between donor and acceptor.And,the solution-processed coassembly could selectively exhibit circularly polarized luminescence with high dissymmetry g-factors.This work illustrates a noncovalent charge-transfer strategy to construct luminescent and chiroptical organic composites based on the easy-accessible and economic chiral N-terminal aromatic amino acids. | Yiran Xia Aiyou Hao Pengyao Xing | 2022 | Chinese Chemical Letters2022，33，11： | 0 |
