1A Robust CRISPR/Cas9 System for Convenient, High-Efficiency Multiplex Genome Editing in Monocot and Dicot Plants显示文摘CRISPR/Cas9 染色体指向系统被用于许多种类。然而,为植物报导的 mostCRISPR/Cas9 系统能仅仅修改一个或一些指向地点。这里,我们报导一个柔韧的 CRISPR/Cas9 向量系统,利用植物 codon 优化了 Cas9 基因,为方便、高效率的复合染色体在 monocot 和 dicot 植物编辑。我们设计了基于 PCR 的过程很快产生多重 sgRNA 表达式盒子,它能在一个轮由金门结扎或吉布森汇编克隆被装配进二进制 CRISPR/Cas9 向量。与这个系统,我们与 85.4% 变化评估的一般水准在米饭编辑了 46 个目标地点,主要在 biallelic 和同型结合的地位。我们推想在米饭的大约 16% 同型结合的变化通过相应基于再结合的修理跟随的非相应的加入结束的机制被产生。我们也获得了一致 biallelic,在 Arabidopsis T 1 植物的异质接合、同型结合、妄想的变化。在米饭和 Arabidopsis 的指向的变化是可继承的。我们在 T 0 米饭和 T 1 由同时的指向的 Arabidopsis 植物多重(多达八) 一个基因家庭,在一条 biosynthetic 小径的多重基因,或在单个基因的多重地点的成员。这个系统为为基本研究和基因改进在植物学习多重基因和基因家庭的功能提供了一个万用的工具箱。Xingliang Ma Qunyu Zhang Qinlong Zhu Wei Liu Yan Chen Rong Qiu Bin Wang Zhongfang Yang Heying Li Yuru Lin Yongyao Xie Rongxin Shen Shuifu Chen Zhi Wang Yuanling Chen Jingxin Guo Letian Chen Xiucai Zhao Zhicheng Dong Yao-Guang Liu 2015Molecular Plant2015,8,8:272
2Development of "Purple Endosperm Rice" by Engineering Anthocyanin Biosynthesis in the Endosperm with a High-Efficiency Transgene Stacking System显示文摘Anthocyanins 在主食庄稼的 anthocyanin 生合成的高抗氧化剂活动,和工程例如米饭(Oryza sativa L.) ,能为改进人的健康提供支持健康的食物。然而,为 biofortification 设计新陈代谢的小径仍然保持困难,并且因为它的 biosynthetic 小径的复杂基因规章的网络,在米饭内乳设计 anthocyanin 生产的以前的尝试失败了。在这研究,我们为叠的 transgene 开发了一个高效率的向量系统并且使用了它在米饭内乳设计 anthocyanin 生合成。我们做了包含内乳特定的倡导者驾驶的八 anthocyanin 相关的基因(从从薄荷科植物的玉米和六结构的基因 ?的二规章的基因) 的构造,加为标记切除的一个可选的标记和基因。有这构造的米饭的转变产生了新奇 biofortified germplasm 紫色内乳瑞斯(用汉语的叫的 Zijingmi ) ,它在内乳有高 anthocyanin 内容和抗氧化剂活动。这 anthocyanin 生产源于 transgenes 和产生激活的表示(或改进) 13 内长的 anthocyanin 生合成基因的表示,那是 silenced 或在野类型的米饭内乳在底层表示。这研究为叠的 transgene 提供一个有效、万用的工具箱并且为一条复杂生物小径的成功的工程表明它的使用,建议为在工厂的农学的特点的合成生物学和改进的这个工具箱的潜在的用途。Qinlong Zhu Suize Yu Dongchang Zeng Hongmei Liu Huicong Wang Zhongtang Yang Xianrong Xie Rongxin Shen Jiantao Tan Heying Li Xiucai Zhao Qunyu Zhang Yuanling Chen Jingxing Guo Letian Chen Yao-Guang Liu 2017Molecular Plant2017,10,7:47
3From Golden Rice to aSTARice:Bioengineering Astaxanthin Biosynthesis in Rice Endosperm显示文摘Carotenoids are important phytonutrients with antioxidant properties,and are widely used in foods and feedstuffs as Supplements.Astaxanthin,a red-colored ketocarotenoid,has strong antioxidant activity and thus can benefit human health.However,astaxanthin is not produced in most higher plants.Here we report the bioengineering of astaxanthin biosynthesis in rice endosperm by introducing four synthetic genes,sZmPSY1,sPaCrtl,sCrBKT,and sHpBHY,which encode the enzymes phytoene synthase,phytoene desaturase,β-carotene ketolase,and β-carotene hydroxylase,respectively.Transgneic overexpression of two (sZmPSY1 and sPaCrtl),three (sZmPSY1,sPaCrtl and sCrBKT),and all these four genes driven by rice endosperm-specific promoters established the Carotenoid/ketocarotenoid/astaxanthin biosynthetic pathways in the endosperm and thus resulted in various types of germplasm,from the yellow-grained β-caro- tene-enriched Golden Rice to orange-red-grained Canthaxanthin Rice and Astaxanthin Rice,respectively. Grains Of Astaxanthin Rice were enriched with astaxanthin in the endosperm and had higher antioxidant activity.These results proved that introduction of a minimal set of four transgenes enables de novo biosynthesis of astaxanthin in therice endosperm.This work provides a Successful example for synthetic biology in plants and biofortification in crops;the biofortified rice products generated by this study could be consumed as health-promoting foods and processed tO produce dietary supplements.Qinlong Zhu Dongchang Zeng Suize Yu Chaojun Cui Jiamin Li Heying Li Junyu Chen Runzhao Zhang Xiucai Zhao Letian Chen Yao-Guang Liu 2018Molecular Plant2018,11,12:35
4Multi-step formation, evolution, and functionalization of new cytoplasmic male sterility genes in the plant mitochondrial genomes显示文摘新基因起源是授与 phenotypic 变化和生物差异的 genomic 革新的主要来源。在植物的新 mitochondrial 基因的产生可以引起细胞质的男绝育(厘米) ,它能支持 outcrossing 和增加健康。然而, mitochondrial 基因怎么在结构和功能发源并且演变,仍然保持不清楚。米饭厘米的野未成功的类型被 mitochondrial 基因 WA352c (以前命名的 WA352 ) 授与并且广泛地在混合米饭繁殖被利用了。这里,我们重建由 11 mitochondrial genomic recombinant 的鉴定和分析的 WA352c 的进化轨道在野、栽培的米饭与 WA352c 有关组织。我们推断这些结构在野米饭 Oryza rufipogon,结合的 substoichiometric 变和顺序变化的 mitochondrial 染色体在保存 mitochondrial 序列之中通过多重重新整理产生了。我们鉴别二表示了,但是在这些结构之中的 nonfunctional protogenes,和他们能发展进功能的厘米基因经由的表演定序能减轻蛋白质的自我禁止的潜力的变化。这些顺序变化将资助蛋白质与编码原子核的 mitochondrial 蛋白质 COX11 交往的能力,在花药 tapetum 和男绝育导致早熟的规划房间死亡。而且,我们证明把 COX11 相互作用领域编码为这些 WA352c 相关的基因的序列经历了在进化期间净化选择。我们经由在结构,顺序,拷贝数字,和功能包含渐渐的变化的 multi-recombination/protogene formation/functionalization 机制为新厘米基因的形成和进化建议一个模型。Huiwu Tang Xingmei Zheng Chuliang Li Xianrong Xie Yuanling Chen Letian Chen Xiucai Zhao Huiqi Zheng Jiajian Zhou Shan Ye Jingxin Guo Yao-Guang Liu 2017Cell Research2017,27,1:11
5Predictors of healthcare-seeking behavior among Chinese patients with irritable bowel syndrome显示文摘AIM To analyze predictors of healthcare-seeking behavior among Chinese patients with irritable bowel syndrome(IBS) and their satisfaction with medical care.METHODS Participating patients met IBS Rome Ⅲ criteria(excluding those with organic diseases) and were enrolled in an IBS database in a tertiary university hospital. Participants completed IBS questionnaires in face-to-face interviews. The questionnaires covered intestinal and extra-intestinal symptoms, medical consultations, colonoscopy,medications, and self-reported response to medications during the whole disease course and in the past year. Univariate associations and multivariate logistic regression were used to identify predictors for frequent healthcareseeking behavior(≥ 3 times/year), frequent colonoscopies(≥ 2 times/year), long-term medications, and poor satisfaction with medical care.RESULTS In total, 516 patients(293 males, 223 females) were included. Participants' average age was 43.2 ± 11.8 years. Before study enrollment, 55.2% had received medical consultations for IBS symptoms. Ordinary abdominal pain/discomfort(non-defecation) was an independent predictor for healthcare-seeking behavior(OR = 2.07, 95%CI: 1.31-3.27). Frequent colonoscopies were reported by 14.7% of patients(3.1 ± 1.4 times per year). Sensation of incomplete evacuation was an independent predictor for frequent colonoscopies(OR = 2.76, 95%CI: 1.35-5.67). During the whole disease course, 89% of patients took medications for IBS symptoms, and 14.7% reported they were satisfied with medical care. Patients with anxiety were more likely to report dissatisfaction with medical care(OR = 2.08, 95%CI: 1.20-3.59). In the past year, patients with severe(OR = 1.74, 95%CI: 1.06-2.82) and persistent(OR = 1.66, 95%CI: 1.01-2.72) IBS symptoms sought medical care more frequently.CONCLUSION Chinese patients with IBS present high rates of frequent healthcare-seeking behavior, colonoscopies, and medications, and low satisfaction with medical care. Intestinal symptoms are major predictors for healthcare-seeking behavior.Wenjuan Fan Dong Xu Min Chang Liming Zhu Guijun Fei Xiaoqing Li Xiucai Fang 2017World Journal of Gastroenterology2017,23,42:5
6Shortened snRNA promoters for efficient CRISPR/Cas-based multiplex genome editing in monocot plants显示文摘Dear Editor,CRISPR(clustered regularly interspaced short palindromic repeats)/Cas genome editing is a powerful tool for introducing specific mutations in organisms including plants.The system is composed of a nuclease such as Cas9 or Cas12a and an engineered single-guide RNA(sgRNA)incorporating a target sequence(Li et al.,2019).A Cas9/sgRNA complex recognizes its target site in the genome,resulting in a mutation at that site.Yu Hao Wubei Zong Dongchang Zeng Jingluan Han Shuifu Chen Jianian Tang Zhe Zhao Xiaojuan Li Kun Ma Xianrong Xie Qinlong Zhu Yuanling Chen Xiucai Zhao Jingxin Guo Yao-Guang Liu 2020Science China(Life Sciences)2020,63,6:4

10Anatomical berry characteristics during the development of grape berries with different shapes显示文摘The aim of this study was to characterize the changes in berry anatomy during the development of grape(Vitis vinifera L.,and Vitis vinifera×Vitis labrusca)with different shapes.Paraffin sectioning was used to examine the structural parameters of the cells.The results revealed that,with the development of berries,the transverse and longitudinal diameters of the flesh cells gradually increased,revealing certain regularity.However,the transverse and longitudinal diameters of the epidermal and sub-epidermal cells were different between varieties,reflecting the specificity of the varieties.The growth of the transverse and longitudinal diameters of the berries was found to be completed in the early stage of development.A combination of correlation analysis and size analysis for each cell layer revealed that,due to the small crosssectional area of the epidermal and sub-epidermal cells,the influence of these cells on the transverse and the longitudinal diameters of the berries would be small.In conclusion,the longitudinal and transverse diameters of the grape berries were mainly determined by the longitudinal and transverse diameters of the flesh cells.The different shapes of the grape berries could mainly be attributed to the different growth rates of the flesh cells in the longitudinal and transverse directions.These different rates of growth led to different lengths and widths of the berry.Chuan Zhang Xiucai Fan Chonghuai Liu Jinggui Fang 2021Horticultural Plant Journal2021,7,4:1

15Stereocontrol during the radical polymerization of methyl methacrylates with combined Lewis acids:Aluminium trichloride(AlCl_3) and iron dichloride tetrahydrate显示文摘The radical polymerization of methyl methacrylate(MMA) was carried out in the presence of combined Lewis acids of the AlCl3-FeCl2 system.Compared with the polymerization produced in the presence of single Lewis acids,AlCl3 or FeCl2,the MMA polymerization in the presence of AlCl3-FeCl2 composite in CHCl3 or 1-butanol produced a polymer with a higher isotacticity and in toluene produced a polymer with a much higher isotacticity(mm=50%) .The molecular weight and polydispersity of PMMA in the presence of Lewis acids were similar with those in the absence of Lewis acids,although Lewis acids decelerate the polymerization of MMA.The effects of the Lewis acids were greater in a solvent with a lower polarity.A possible stereocontrol mechanism of the polymerization was proposed.The Lewis acid composite of AlCl3-FeCl2 readily formed a complex with growing species.These complexes possessed apparent bulkiness that changes the direction of monomer addition to the growing radical center.SANG Qian,FENG Ying ,DONG XiuCai & ZHAO JiRuo Key Laboratory of Rubber-Plastics,Ministry of Education Qingdao University of Science and Technology,Qingdao 266042,China 2010Science China Chemistry2010,53,5:1
