[Objectives] The paper was to clone and analyze bioinformatics of ndk gene from Vibrio alginolyticus. [Methods] A pair of specific primers was designed based on the ndk gene sequence of V. alginolyticus HY9901. The full length of ndk gene was amplified by PCR and bio informatics analysis was performed. MEGA 5.0 software was used to construct NDK phylogenetic tree by neighbor-joining method. SWISS-MODEL program was used to obtain the three-dimensional structural model of single subunit from NDK protein. [Results] The ndk gene, molecular structural formula C7CB Hlow N]92 02J4 S7, was 426 bp in total, encoding 141 amino acids, with the theoretical molecular weight of 15.871 99 kD and the theoretical pl value of 5.13. The prediction results of protein subcellular localization, Signal? 5. 0, TMHMM Server 2.0 and SoftBerry-Psite showed that NDK mainly existed in the cytoplasm, and the protein was unstable and hydrophobic. There was neither signal peptide cleavage site, nor transmembrane region and KEGG metabolic pathway. The amino acid sequence had two protein kinase C phosphorylation sites, a casein kinase II phosphorylation site, a N-myristoylation site, three microbody C-terminal target signal sites, and a nucleoside diphosphate kinase active site. Homology analysis showed that the NDK of V. alginolyticus had high homology with that of V. diabolicus, with a similarity of 98.58%. Analysis of the structural functional domain revealed that the protein had one NDK structural functional domain. The prediction results of secondary structure showed that the a-helix, random coil, [3-sheet and extended strand accounted for 53.19%, 28.37%, 7.09% and 11.35%, respectively. Analysis of NDK protein via STRING database demonstrated that the proteins interacting with NDK protein were NrdA, NrdB, GmK, CmK, TmK, PyrG, PyrH, RelA, FolE and SpoT. [Conclusions] The study plays a positive role in the prevention and control of vibriosis and the improvement of the current aquaculture environment. [ABSTRACT FROM AUTHOR]

In northern China's agro-pastoral ecotone, there are conflicts between agricultural industry and ecological construction resource competition, and also problems urgently to be solved for economic growth and sustainable ecological improvement. Taking the development concept of "lucid waters and lush mountains being mountains of gold and silver" as the guiding principle of prioritizing ecological and green development, this paper studied the strategies for prioritizing ecological construction with consideration of economic development of agricultural industry from the perspective of opportunity cost. Through the analysis of opportunity cost, externality, and Pareto optimal theory, and using the calculation method of the unit equivalent factor value of terrestrial ecological service function, this paper calculated the ecological service value of forest, grassland, and farmland. It found that the ecological value of forest and grassland per unit area was greater than the ecological value of agricultural industry. This indicates that the opportunity cost of farmland for ecological construction was less than that of agricultural industry. Based on the theoretical and quantitative analysis, it came up with recommendations for establishing a comprehensive system for prioritizing ecological construction with consideration of agricultural industry development and establishing and improving the incentive mechanism of ecological construction.

The results show that the export trade volume of cocoon silk of China and Southeast Asia is decreasing while fluctuating,but it is difficult for other regions to replace their export trade status in the world market. The development trend of the replacement of the silkworm cocoon trade by the raw silk trade is presented. The cocoon silk trade of China and Southeast Asia is characterized by dislocation competition. China’s raw silk export trade is competitive and has become the leader of the raw silk export camp. This paper further analyzes the changes and complementarities of the cocoon silk trade competitiveness between China and Southeast Asia. [ABSTRACT FROM AUTHOR]

Due to the differences in regional resources level, economic development level and government support strength, there are clear regional differences in the development of China's agricultural producer service industry. Based on the data of agricultural producer services from 31 provinces in China from 2003 to 2016, the spatial differences in the development level of China's agricultural producer services were measured in this paper using the Theil index. The results showed that there are significant spatial differences in China's agricultural producer services, and regional differences are the main reason for the overall differences. To reveal the influencing factors of the spatial differences in the level of development of China's agricultural producer services, theoretical analysis was conducted in this paper from four aspects: location factors, economic factor, policy factor and technical factors. Using the panel data from 2003 to 2016, empirical research was carried out. It was found that regional economic development level and government support strength are the main factors affecting the differences in the development level of agricultural producer services in China.

[Objectives] This study was conducted to gain an in-depth understanding of the research status of fields related to soil aggregates. [ Methods] The academic papers published from 2001 to 2020 in the field of soil aggregates were searched in the CNKI database serving as the statistical source using the subject terms "soil" and "aggregate" under advanced search, and visually analyzed by bibliometric statistical methods, from the perspectives of the annual number of published papers, the number of papers published by authors, and highly cited papers. [ Results] The trend of the number of published papers in the past 20 years was mainly divided into three stages; 2001 -2007, 2008 - 2016, and 2017 -2020. There were 192 first authors in the literature related to soil aggregates. The authors with the top 3 published papers were Wang Erli, 2hang 2hengxiong, Li Yangbing, and Yang Yonghui (tied for third). Three highly cited papers were published in journals related to "ecology", and the top 10 most cited papers focused on the "formation and stability" of soil aggregates and the relationship between aggregates and soil organic matter and biochar. [ Conclusions] This study can provide reference for further research on soil aggregates. [ABSTRACT FROM AUTHOR]

Vocational colleges attach great importance to labor education. Specialized courses are an effective way to cultivate students' labor quality, and the integration of labor education in specialized courses plays an important role in the overall cultivation of students' moral quality and practical ability. Combined with the teaching practice of landscape technology specialty, labor education is integrated into the teaching of Plant Cultivation and Maintenance, and certain results have been achieved. In this paper, the course content "grafting propagation" was analyzed from the aspects of overall teaching design, teaching implementation process, teaching effect and reflection improvement, so as to provide reference for other contents of this major or other majors to carry out integrated teaching.

[Objectives] The paper was to establish a molecular biological method for identification of bacterial strains. [Methods] The thalli of standard bacterial strains existing in the laboratory were collected and genomic DNA was extracted for amplification of 16S rDNA and gyrB gene. The 16S rDNA and gyrB gene sequences were obtained after sequencing. Sequences were aligned and analyzed via EzBioCloud and NCBI database, and phylogenetic trees were constructed to determine the species relationship of strains. Meantime, they were compared with known strains. [Results] This method could identify 5 standard strains accurately to the species level. The 16S rDNA and gyrB gene sequences were aligned and analyzed in EzBioCloud database and NCBI database. The strain with the max score was consistent with the known strain. And the query cover and ident were both above 99%. [Conclusions] The established molecular biological method for identification of bacterial strains by 16S rDNA and gyrB gene has good accuracy, which effectively solves the problem that the laboratory identification of bacteria relies on traditional methods and the accuracy can not be guaranteed, and further improves the identification ability of laborator)' bacterial strains.
