| 1 | Fermented soybean meal improves the growth performance, nutrient digestibility, and microbial flora in piglets显示文摘In order to increase nutritive values of soybean meal(SBM), 3 species of microbes were used to ferment SBM. Through a 3 x 3 orthogonal design and parameter measurements of soybean peptide and antinutritional factor contents in the fermented soybean meal(FSBM), it was estimated that the best microbial proportion of Bacillus subtilis, Hansenula anomala and Lactobacillus casei was 2:1:2 for SBM fermentation(P < 0.05). The further piglet feeding experiment showed that 10% FSBM substitute for SBM had no significant effect on growth performance of suckling piglets(d 7-28)(P> 0.05). However, newlyweaned piglets(d 28-38) fed 10% FSBM and different levels of plasma protein obtained higher average daily gain(ADG) and feed conversion ratio(FCR), compared with those without FSBM but with 6% plasma protein(P < 0.05). Piglets(d 38-68) fed diets supplemented with FSBM and soybean protein concentrate(SBPC) at 3.75% and 7.5% respectively increased nutrient digestibility,fecal enzyme activity and lactic acid bacteria counts, and decreased fecal Escherichia coli counts(P < 0.05), compared with the control. These data indicated that FSBM had positive effects on nutrient digestibility and fecal microflora for piglets. | Lin Yuan Juan Chang Qingqiang Yin Min Lu Yuanran Di Ping Wang Zhixiang Wang Erzhu Wang Fushan Lu | 2017 | Animal Nutrition2017，，1： | 31 |

| 3 | Postharvest Treatment with β-Aminobutyric Acid Induces Resistance Against Dry Rot Caused by Fusarium sulphureum in Potato Tuber显示文摘The effectiveness of postharvest β-aminobutyric acid (BABA) treatment was studied for inducing resistance against dry rot caused by Fusarium sulphureum in tubers and slices of two potato cultivars (resistant cultivar Shepody and susceptible cultivar Xindaping). The results showed that BABA at 100 mmol L-1 significantly reduced lesion diameter in inoculated both tubers and slices. The chemical at 100 mmol L-1 showed an effective reduction in infection ability of F. sulphureum inoculated 48 and 72 h after treatment in slices of resistant cultivar, and 72 and 96 h in susceptible ones. BABA increased the activitives of peroxidase (POD), polyphenoloxidase (PPO) and phenylalanine ammonialyase (PAL), and accumulated the contents of lignin, flavonoids and phenolics in slices. The resistant cultivar had a stronger resistant response than the susceptible one. These findings suggest that the BABA treatment can induce the resistance in potato tubers, however, the inducing degree depends on the original level of resistance present in each cultivar. | YIN Yan LI Yong-cai BI Yang CHEN Song-jiang LI Ying-chao YUAN Li WANG Yi WANG Di | 2010 | Agricultural Sciences in China2010，9，9： | 24 |
| 4 | Rice CYP703A3, a cytochrome P450 hydroxylase, is essential for development of anther cuticle and pollen exine显示文摘Anther cuticle and pollen exine act as protective envelopes for the male gametophyte or pollen grain, but the mechanism underlying the synthesis of these lipidic polymers remains unclear. Previously, a tapetum‐expressed CYP703A3, a putative cytochrome P450 fatty acid hydroxylase, was shown to be essential for male fertility in rice(Oryza sativa L.). However,the biochemical and biological roles of CYP703A3 has not been characterized. Here, we observed that cyp703a3‐2 caused by one base insertion in CYP703A3 displays defective pollen exine and anther epicuticular layer, which differs from Arabidopsis cyp703a2 in which only defective pollen exine occurs. Consistently, chemical composition assay showed that levels of cutin monomers and wax components were dramatically reduced in cyp703a3‐2 anthers. Unlike the wide range of substrates of Arabidopsis CYP703A2, CYP703A3 functions as an in‐chain hydroxylase only for a specific substrate, lauric acid, preferably generating 7‐hydroxylated lauric acid. Moreover, chromatin immunoprecipitation and expression analyses revealed that the expression of CYP703A3 is directly regulated by Tapetum Degeneration Retardation, a known regulator of tapetum PCD and pollen exine formation. Collectively, our results suggest that CYP703A3 represents a conserved and diversified biochemical pathway for in‐chain hydroxylation of lauric acid required for the development of male organ in higher plants. | Xijia Yang Di Wu Jianxin Shi Yi He Franck Pinot Bernard Grausem Changsong Yin Lu Zhu Mingjiao Chen Zhijing Luo Wanqi Liang Dabing Zhang | 2014 | Journal of Integrative Plant Biology2014，56，10： | 21 |

| 15 | Candidate genes involved in the biosynthesis of lignan in Schisandra chinensis fruit based on transcriptome and metabolomes analysis显示文摘Schisandra chinensis Turcz.(Baill.) is a plant species with fruits that have been well known in Far Eastern medicine for a long time. It has traditionally been used as a stimulating and fortifying agent in cases of physical exhaustion and to inhibit fatigue.The major bioactive compounds found in S. chinensis are lignans with a dibenzocyclooctadiene skeleton, but little is known about their biosynthesis in plants. S. chinensis is the ideal medicinal plant for studying the biosynthesis of lignans, especially the dibenzocyclooctadiene skeleton. Genomic information for this important herbal plant is unavailable. To better understand the lignan biosynthesis pathway, we generated transcriptome sequences from the fruit during ripening and performed de novo sequence assembly, yielding136 843 unique transcripts with N50 of 1778 bp. Putative functions could be assigned to 41 824 transcripts(51.57%) based on BLAST searches against annotation databases including GO(Gene ontology) and KEGG(Kyoto Encyclopedia of Genes and Genomes). Furthermore, 22 candidate cytochrome P450 genes and 15 candidate dirigent proteins genes that were most likely involved in the lignan biosynthesis pathway were discovered based on transcriptome sequencing of S. chinensis. The genomic data obtained from S. chinensis, especially the identification of putative genes involved in the lignan biosynthesis pathway, will facilitate our understanding of lignan biosynthesis at the molecular level. The lignan metabolite profiles were analyzed by metabolomes, the accumulation patterns of 30 metabolites involved in the lignan pathway were studied. Co-expression network of lignan contents and transcriptional changes showed355 strong correlations(correlation coefficient, R^2 > 0.9) between 21 compounds and 153 transcripts. Furthermore, the comprehensive analysis and characterization of the genes involved in lignan pathways and the metabolite profiles of lignans are expected to provide better insight regarding the diversity of the chemical composition, synthetic characteristics, and regulatory mechanisms of this medical herb. | CHEN Chun-Yu LIU Shu-Ying YAN Yan YIN Le DI Peng LIU Hui-Min LIU Hong-Zhang | 2020 | Chinese Journal of Natural Medicines2020，18，9： | 5 |
| 16 | Construction of NH2-MIL-125(Ti)/Bi2WO6 composites with accelerated charge separation for degradation of organic contaminants under visible light irradiation显示文摘Photocatalysis is considered as an ideal strategy for water pollution treatment.However,it remains challenging to design a highly efficient photo-catalytic system through regulating the charge flow via a precise approach.In this work,a novel NH2-MIL-125(Ti)/Bi2WO6 composite was constructed via self-assembly growing Bi2WO6 nanosheets on NH2-MIL-125(Ti)material.The characterization results demonstrated that NH2-MIL-125(Ti)was successfully incorporated into Bi2WO6 and the photoexcited carriers could be efficiently separated and transferred between the two components.NH2-MIL-125(Ti)/Bi2WO6 composites displayed enhanced photocatalytic activity for the removal of rhodamine B(RhB)and tetracycline(TC)under visible light irradiation,and the optimal weight ratio of NH2-MIL-125(Ti)was determined to be 7 wt%.The introduction of NH2-MIL-125(Ti)into Bi2WO6 could raise the absorption of visible light,accelerate the separation and transfer of charge carriers,and boost photocatalytic activity.This research presents a wide range of possibilities for the further development of novel composites in the field of environment purification. | Sheng Yin Yong Chen Ming Li Qingsong Hu Yi Ding Yifan Shao Jun Di Jiexiang Xia Huaming Li | 2020 | Green Energy & Environment2020，5，2： | 5 |
| 17 | Distinct immune signatures discriminate between asymptomatic and presymptomatic SARS-CoV-2^(pos)subjects显示文摘Increasing numbers of SARS-CoV-2-positive(SARS-CoV-2^(pos))subjects are detected at silent SARS-CoV-2 infection stage(SSIS).Yet,SSIS represents a poorly examined time-window wherein unknown immunity patterns may contribute to the fate determination towards persistently asymptomatic or overt disease.Here,we retrieved blood samples from 19 asymptomatic and 12 presymptomatic SARS-COV-2^(pos)subjects,47 age/gender-matched patients with mild or moderate COVID-19 and 27 normal subjects,and interrogated them with combined assays of 44-plex CyTOF,RNA-seq and Olink.Notably,both asymptomatic and presymptomatic subjects exhibited numerous readily detectable immunological alterations,while certain parameters including more severely decreased frequencies of CD107a^(low)classical monocytes,intermediate monocytes,non-classical monocytes and CD62L^(hi)CD8^(+)Tnaive cells,reduced plasma STC1 level but an increased frequency of CD4^(+)NKT cells combined to distinguish the latter.Intercorrelation analyses revealed a particular presymptomatic immunotype mainly manifesting as monocytic overactivation and differentiation blockage,a likely lymphocyte exhaustion and immunosuppression,yielding mechanistic insights into SSIS fate determination,which could potentially improve 5ARS-CoV-2 management. | Shanhe Yu Caixia Di Shijun Chen Mingquan Guo Jiayang Yan Zhaoqin Zhu Li Liu Ruixue Feng Yinyin Xie Ruihong Zhang Juan Chen Mengxi Wang Dong Wei Hai Fang Tong Yin Jinyan Huang Saijuan Chen Hongzhou Lu Jiang Zhu Jieming Qu | 2021 | Cell Research2021，31，11： | 4 |

| 19 | Molecular and Epidemiological Characterization of Infant Botulism in Beijing, China显示文摘Laboratory-based pathogen isolation, identification, and toxicity determination were performed on samples from a suspected case of infant botulism. Mice injected with cultures generated from the enema sample and ingested Powered infant formula(PIF) presented typical signs of botulism. Antitoxins to polyvalent botulinum neurotoxins(BoNTs) and monovalent BoNT type B antitoxin had protective effects. Clostridium botulinum isolated from the enema and residual PIF samples were positive for type B toxin. Pulsed-field gel electrophoresis(PFGE) revealed that the two strains of C. botulinum isolated from the two samples produced indistinguishable pulsotypes. These findings confirmed this case of type B infant botulism associated with the ingestion of PIF contaminated by type B C. botulinum spores. | DONG Yin Ping WANG Wei JIANG Tao XU Jin HAN Chun Hui YAN Shao Fei Séamus Fanning LI Ying MA Xiao Chen ZHANG Di ZHAO Yao ZENG Biao LI Feng Qin | 2017 | Biomedical and Environmental Sciences2017，30，6： | 4 |
