| 1 | Nucleocytoplasmic Trafficking of the Arabidopsis WD40 Repeat Protein XIW1 Regulates ABI5 Stability and Abscisic Acid Responses显示文摘WD40 repeat-containing proteins(WD40 proteins)serve as versatile scaffolds for protein-protein interac-tions,modulating a variety of cellular processes such as plant stress and hormone responses.Here we report the identification of a WD40 protein,XIW1(for XPO1-interacting WD40 protein 1),which positively regulates the abscisic acid(ABA)response in Arabidopsis.XIW1 is located in the cytoplasm and nucleus.We found that it interacts with the nuclear transport receptor XPO1 and is exported by XPO1 from the nucleus.Mutation of XIW1 reduces the induction of ABA-responsive genes and the accumulation of ABA Insensitive 5(ABI5),causing mutant plants with ABA-insensitive phenotypes during seed germination and seedling growth,and decreased drought stress resistance.ABA treatment upregulates the expression of XIW1,and both ABA and abiotic stresses promote XIW1 accumulation in the nucleus,where it interacts with ABI5.Loss of XIW1 function results in rapid proteasomal degradation of ABI5.Taken together,these findings suggest that XIW1 is a nucleocytoplasmic shuttling protein and plays a positive role in ABA responses by interacting with and maintaining the stability of ABI5 in the nucleus. | Xuezhong XU Wang Wan Guobin Jiang Yue Xi Haijian Huang Jiajia Cai Yanan Chang Cheng-Guo Duan Satendra KMangrauthia Xinxiang Peng Jian-Kang Zhu Guohui Zhu | 2019 | Molecular Plant2019，12，12： | 8 |
| 2 | Mining the key regulatory genes of chicken inosine 5'-monophosphate metabolism based on time series microarray data显示文摘IMP(inosine 5'-monophosphate) is a compound that enhances the flavor of poultry meat.IMP has become a new breeding trait to improve poultry meat quality.We tried to identify several potential regulatory genes,and construct their predicted regulatory relationships.Time series gene expression profiles of thigh muscle tissues of Rugao chicken,a famous indigenous breed in China,were performed for analysis of genes that are co-expressed or correlated with the concentration of IMP.We found 15 crucial co-expression genes,which are Hspa2,Pten,Gabpa,Bpi,Mkl1,Srf,Cd34,Hspa4,Etv6,Bmpr2,Gde1,Igfbp5,Cd28,Pecam1 and Gja1,that may directly or indirectly regulate IMP metabolism.Eventually,we computed the correlation coefficient between 19 IMP Genes and 15 CGs(15co-expression genes),and we identified and constructed a predicted regulation network.In conclusion,variation of IMP concentration was primarily connected with the muscle development process.During this process,15 CGs were identified that may have significant influence on IMP metabolism.In particular,Bmpr2,Pten and co-expression genes correlated with Entpd8 might play important roles in regulating IMP de novo synthesis,decomposition and salvage synthesis. | Teng Ma Lu Xu Hongzhi Wang Jing Chen Lu Liu Guobin Chang Guohong Chen | 2015 | Journal of Animal Science and Biotechnology2015，6，3： | 6 |
| 3 | Molecular cloning and expression patterns of the cholesterol side chain cleavage enzyme(CYP11A1) gene during the reproductive cycle in goose(Anas cygnoides)显示文摘Background: CYP11A1, a gene belonging to the family 11 of cytochrome P450, encodes a crucial steroidogenic enzyme that catalyzes the initial step in the production of all classes of steroids. Many studies show that CYP11A1 plays a role in ovary function. However, the role of CYP11A1 in goose reproductive cycle remains largely unknown.Results: In this study, full-length CYP11A1 c DNA of Zhedong goose was obtained using reverse transcription polymerase chain reaction(RT-PCR) and rapid amplification of c DNA ends(RACE). The c DNA consisted of a 96-base pair(bp) 5′untranslated region(UTR), a 179-bp 3′UTR and a 1509-bp open reading frame. The open reading frame encodes a putative 503 amino acid protein that shares high homology with CYP11A1 of other birds. The amino acid sequence possesses conserved domains of the P450 superfamily, which include the steroid-binding domain and the heme-binding region. Real-time quantitative polymerase chain reaction(q PCR) analysis revealed CYP11A1 mR NA was expressed ubiquitously in every Zhedong goose tissue analyzed, including the heart, liver, glandular stomach,lung, spleen, kidney, intestinum tenue, intestinum crassum, cerebrum, cerebellum, muscle, oviduct, pituitary,hypothalamus and ovary.. The relatively low levels of CYP11A1 m RNA were detected in pituitary, ovary and oviduct tissues at ovulation when compared with levels at oviposition. Interestingly, higher expression was observed in ovary and oviduct tissues during brooding. Lastly, higher m RNA expression of Yangzhou geese was detected during the ovulation period than that of Zhedong geese.Conclusions: Our findings reveal the sequence characterization and expression patterns of the CYP11A1 gene during the goose reproductive cycle, which may provides correlative evidence that CYP11A1 expression is important in reproduction activity. | Qi Xu Yadong Song Yang Chen Ran Liu Yang Zhang Yang Li Zhengyang Huang Wenming Zhao Guobin Chang Guohong Chen | 2016 | Journal of Animal Science and Biotechnology2016，7，2： | 2 |
| 4 | The analysis of genetic diversity and differentiation of six Chinese cattle populations using microsatellite markers显示文摘A total of 321 individuals from six cattle populations of four species in a bovine subfamily in China were studied using 12 pairs of mi- crosatellite markers. The genetic diversities within and between populations were calculated. The phylogenetic trees were constructed by (δμ) 2 and DA distances, and the divergence times between populations were estimated by (δμ) 2. Altogether, 144 microsatellite alleles were detected including 24 private alleles and nine shared alleles. Chinese Holstein had the largest number of private alleles (10), whereas, Bohai black and Buffalo had the smallest number of private alleles (2). Chinese Holstein showed the highest genetic variability. Its ob- served number of alleles (Na), mean effective number of alleles (MNA), and mean heterozygosity (He) were 7.7500, 4.9722, and 0.7719, respectively, whereas, the Buffalo and Yak showed low genetic variability. In the phylogenetic trees, Luxi and Holstein grouped first, followed by Bohai and Minnan. Yak branched next and buffalo emerged as the most divergent population from other cattle populations. Luxi and Bohai were estimated to have diverged 0.039-0.105 million years ago (MYA), however, buffalo and Holstein diverged 0.501-1.337 MYA. The divergence time of Yak versus Minnan, Holstein and buffalo was 0.136-0.363, 0.273-0.729, and 0.326-0.600 MYA, respectively. | Yongjiang Mao Hong Chang Zhangping Yang Liu Zhang Ming Xu Guobin Chang Wei Sun Guangming Song Dejun Ji | 2008 | Journal of Genetics and Genomics2008，35，1： | 2 |

| 11 | The First Crested Duck Genome Reveals Clues to Genetic Compensation and Crest Cushion Formation显示文摘The Chinese crested(CC)duck is a unique indigenous waterfowl breed,which has a crest cushion that affects its survival rate.Therefore,the CC duck is an ideal model to investigate the genetic compensation response to maintain genetic stability.In the present study,we first generated a chromosome-level genome of CC ducks.Comparative genomics revealed that genes related to tissue repair,immune function,and tumors were under strong positive selection,indicating that these adaptive changes might enhance cancer resistance and immune response to maintain the genetic stability of CC ducks.We also assembled a Chinese spot-billed(Csp-b)duck genome,and detected the structural variations(SVs)in the genome assemblies of three ducks(i.e.,CC duck,Csp-b duck,and Peking duck).Functional analysis revealed that several SVs were related to the immune system of CC ducks,further strongly suggesting that genetic compensation in the anti-tumor and immune systems supports the survival of CC ducks.Moreover,we confirmed that the CC duck originated from the mallard ducks.Finally,we revealed the physiological and genetic basis of crest traits and identified a causative mutation in TAS2R40 that leads to crest formation.Overall,the findings of this study provide new insights into the role of genetic compensation in adaptive evolution. | Guobin Chang Xiaoya Yuan Qixin Guo Hao Bai Xiaofang Cao Meng Liu Zhixiu Wang Bichun Li Shasha Wang Yong Jiang Zhiquan Wang Yang Zhang Qi Xu Qianqian Song Rui Pan Lingling Qiu Tiantian Gu Xinsheng Wu Yulin Bi Zhengfeng Cao Yu Zhang Yang Chen Hong Li Jianfeng Liu Wangcheng Dai Guohong Chen | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
| 12 | Proteomic and phosphoproteomic analysis reveal threonine deficiency increases hepatic lipid deposition in Pekin ducks via reducing STAT phosphorylation显示文摘Dietary threonine(Thr)deficiency enhances triglyceride(TG)deposition in the liver of Pekin ducks,which injures hepatic function and impairs growth performance.However,the underlying molecular mechanisms remain unclear.In the present study,we investigated the effects of dietary Thr deficiency on the expressions of proteins and phosphoproteins in liver of Pekin ducks,to identify the underlying molecular changes.A total of 300 one-day-old ducklings were divided into 3 groups with 10 replicates of 10 birds.All ducks were fed corn-wheat-peanut meal diets containing 0.46%,0.71%,and 0.96%Thr,respectively,from 1 to 21 days of age.Growth performance,serum parameters,hepatic TG content,and expression of genes involved in lipid metabolism of Pekin ducks were determined.A Thr deficiency group(Thr-D,0.46%Thr)and a Thr sufficiency group(Thr-S,0.71%Thr)were selected for subsequent proteomic and phosphoproteomic analysis.The results showed that Thr-D reduced the growth performance(P<0.001),and increased the plasma concentrations of cholesterol,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,and hepatic TG(P<0.05).Thr-D increased gene expression related to fatty acid and TG synthesis(P<0.05).A total of 176 proteins and 259 phosphosites(containing 198 phosphoproteins)were observed to be differentially expressed as a result of Thr-D.The upregulated proteins were enriched in the pathway related to amino acid metabolism,peroxisome.The down-regulated proteins were enriched in linolenic and arachidonic acid metabolism,and the Janus kinase-signal transducer and activator of transcription(JAK-STAT)signaling pathway.The upregulated phos-phoproteins were enriched in the pathways related to fatty acid biosynthesis,fructose and mannose metabolism,and glycolysis/gluconeogenesis.Thr-D reduced the phosphorylation of STAT1 at S729 and STAT3 at S728,and expression of STAT5B.In contrast,Thr-D increased non-receptor tyrosine-protein kinase(TYK2)expression and STAT1 phosphorylation at S649.Taken together,dietary Thr-D increased hepatic TG accumulation by upregulating the expression of genes and proteins,and phosphoproteins related to fatty acid and triglyceride synthesis.Furthermore,these processes might be regulated by the JAK-STAT signaling pathway,especially the phosphorylation of STAT1 and STAT3. | Yong Jiang Zhong Zhuang Wenqia Jia Zhiguo Wen Ming Xie Hao Bai Yulin Bi Zhixiu Wang Guobin Chang Shuisheng Hou Guohong Chen | 2023 | Animal Nutrition2023，，2： | 0 |
