3PtHAK5, a candidate for mediating high-affinity K^+ uptake in the halophytic grass, Puccinellia tenuiflora显示文摘Puccinellia tenuiflora is a typical salt-excluding halophytic grass with strong salt-tolerance, which enhances tolerance by restricting Na^+influx as well as having a strong selectivity for K^+ over Na^+. The HAK5 K^+ transporters generally modulate effective K^+acquisition in plants, especially under low K^+ condition. In this study,Pt HAK5 from P. tenuiflora was isolated by RT-PCR and characterized using yeast complementation. The results showed Pt HAK5 consisted of 784 amino acids and shared over 80% homology with the identified high-affinity K^+ transporter HAK5 from other higher plants. The expression of PtHAK5 rescued the K^+ -uptake-defective phenotype of yeast strain CY162. In conclusion, PtHAK5 is a candidate for mediating high-affinity K^+ uptake under low K^+ conditions.Haili YANG Weidan ZHANG Weiwei CHAI Wenying WANG Li GAO Jing ZHANG Yongping WANG Suo-Min WANG 2018Frontiers of Agricultural Science and Engineering2018,5,1:1
4Analysis of Genomic Genetic Diversity of Cucurbit Aphidborne Yellows Virus显示文摘[Objectives]This study was conducted to investigate the molecular characteristics,genetic structure and evolutionary mechanism of cucurbit aphid-borne yellows virus(CABYV),which is of great significance for clarifying the epidemic laws of the disease in the field and formulating long-term sustainable control strategies.[Methods]120 melon leaves suspected to be infected with CABYV were randomly collected from Aksu City,Xinjiang.RT-PCR was used to detect the virus.MEGA 7.0 was used to construct a phylogenetic tree.DnaSP v5.10 was used to analyze the genetic diversity among different sequences,and RDP v.4.31 software was used to analyze possible recombination events of CABYV sequence.[Results]The detection rate of CABYV was 31.67%.A new CABYV-2 was isolated,sequenced and cloned from these positive samples.The length of the genome is 5497 bp,encoding six open reading frames.Compared with 23 CABYV strains isolated from different countries in NCBI database,CABYV-2 shared the highest homology with KR231942.1 and the lowest homology with JF939812.1.The results of evolutionary tree analysis showed that the 24 isolates were divided into two branches due to different geographical factors,including CABYV-2 and KR2319421,which were clustered together and belonged to branch 1.The results of genetic diversity and neutrality tests showed that CABYV was highly variable and the population was expanding.The results of recombination analysis showed that there were two recombinants,EU636992.1 and KR231949.1,which exacerbated the variation of CABYV.[Conclusions]The CABYV isolate from Aksu City,Xinjiang had the closest relationship with the Korean isolate KR231942.1,and the farthest relationship with the isolates from European countries.There were large genetic differences between the isolates of branch 1 and branch 2,and the recombination of CABYV in different hosts aggravated the variation of CABYV.Recombination and negative selection may be important reasons for the genetic variation of CABYV.Wei CHEN Lina NIU Zhengxiu CUI Yongping LUO Juan HE Min CHAI Maimaiti YUSHANJIANG 2022Agricultural Biotechnology2022,11,4:0

7A Pd_(2)L_(4) Metallacage-Cored Supramolecular Amphiphile and Its Application in Dual-Responsive Controllable Release显示文摘The construction of multi-responsive supramolecular systems for drug delivery is a challenging task.In this work,a Pd_(2)L_(4) metallacage 1·([BF_(4)]^(−))_(4) with four pyrene units was first designed and synthesized through coordination-driven self-assembly.After the introduction ofγ-CD,a supramolecular amphiphile 1–γ-CD was successfully constructed based on the host–guest molecular recognition betweenγ-CD and the pyrene unit of 1·([BF_(4)]^(−))_(4),which further self-assembled into dual-responsive supramolecular vesicles in aqueous solution.DOX·HCl was used as a model molecule to study the drug encapsulation and release behavior of the supramolecular vesicles.By adjusting the pH of the solution to acidic condition or adding a certain amount ofα-amylase,the vesicle structure was destroyed to achieve rapid and effective release of the drug molecules.This study provides an example for the rational design of efficient dual-responsive supramolecular nanocarriers,which have potential application value in the field of controlled drug delivery.Yongping Chai Peng Qin Xupeng Li Tai-Bao Wei Qi Lin You-Ming Zhang Hong Yao Wen-Juan Qu Bingbing Shi 2022Chinese Journal of Chemistry2022,40,20:0
8A paternal protein facilitates sperm RNA delivery to regulate zygotic development显示文摘Sperm contributes essential paternal factors,including the paternal genome,centrosome,and oocyte-activation signals,to sexual reproduction.However,it remains unresolved how sperm contributes its RNA molecules to regulate early embryonic development.Here,we show that the Caenorhabditis elegans paternal protein SPE-11 assembles into granules during meiotic divisions of spermatogenesis and later matures into a perinuclear structure where sperm RNAs localize.We reconstitute an SPE-11 liquid-phase scaffold in vitro and find that SPE-11 condensates incorporate the nematode RNA,which,in turn,promotes SPE-11 phase separation.Loss of SPE-11 does not affect sperm motility or fertilization but causes pleiotropic development defects in early embryos,and spe-11 mutant males reduce m RNA levels of genes crucial for an oocyte-to-embryo transition or embryonic development.These results reveal that SPE-11 undergoes phase separation and associates with sperm RNAs that are delivered to oocytes during fertilization,providing insights into how a paternal protein regulates early embryonic development.Dongdong Li Shijing Huang Yongping Chai Ruiqian Zhao Jing Gong Qiangfeng Cliff Zhang Guangshuo Ou Wenyu Wen 2023Science China(Life Sciences)2023,66,10:0
9CACA guidelines for holistic integrative management of glioma显示文摘Glioma of the brain is a kind of tumor originating from neuroglial cells.It is the most common primary intracranial tumor,accounting for~30%of all central nervous system tumors and 80% of malignant brain tumors.Glioma is characterized by high disability and recurrence rates.The disease seriously threatens the life of patients,afects their quality of life,and brings a heavy economic and psychological burden to patients,families,and society.With the progression of molecular genetic testing technology and the completion of various clinical trials,the classifcation scheme for glioma is increasingly well established.Diagnosis and treatment regimens,including traditional and new regimens,are becoming increasingly specialized and standardized.The purpose is to develop a clinical diagnosis and treatment guideline for glioma in the Chinese population suitable for Chinese doctors and the general population based on domestic and international glioma research progress.Thus,domestic practitioners in the feld can obtain current information and provide better service to patients with glioma,promoting the development of domestic clinical medicine and basic research on glioma.Daiming Fan Tao Jiang Wenbin Ma Chuanlu Jiang Yongping You Ying Mao Xiaoguang Qiu Chunsheng Kang Gang Li Qing Mao Xuejun Yang Zhiyong Qin Zhixiong Liu Weimin Wang Xinting Wei Wenbin Li Yunhui Liu Rutong Yu Xinguang Yu Dezhi Kang Yonggao Mou Lei Wang Wei Zhang Zhaoshi Bao Ruichao Chai Baoshi Chen Xing Fan Shengyu Fang Guanzhang Li Lianwang Li Shouwei Li Xing Liu Yanwei Liu Xia Shan Liang Wang Yinyan Wang Yu Wang Zheng Wang Zhiliang Wang Chenxing Wu Wei Yan Pei Yang Gan You Chuanbao Zhang Zhong Zhang Zheng Zhao 2022Holistic Integrative Oncology2022,1,1:0
