Non-human primates (NHPs) are phylogenetically close to humans, with many similarities in terms of physiology, anatomy, immunology, as well as neurology, all of which make them excellent experimental models for biomedical research. Compared with developed countries in America and Europe, China has relatively rich primate resources and has continually aimed to develop NHPs resources. Currently, China is a leading producer and a major supplier of NHPs on the international market. However, there are some deficiencies in feeding and management that have hampered China's growth in NHP research and materials. Nonetheless, China has recently established a number of primate animal models for human diseases and achieved marked scientific progress on infectious diseases, cardiovascular diseases, endocrine diseases, reproductive diseases, neurological diseases, and ophthalmic diseases, etc. Advances in these fields via NHP models will undoubtedly further promote the development of China's life sciences and pharmaceutical industry, and enhance China's position as a leader in NHP research. This review covers the current status of NHPs in China and other areas, highlighting the latest developments in disease models using NHPs, as well as outlining basic problems and proposing effective to better utilize NHP resources and further foster NHP research in China. 展开更多

Genome editing technologies have revolutionized the field of plant science by enabling targeted modification of plant genomes and are emerging as powerful tools for both plant gene functional analyses and crop improvement. Although homology-directed repair(HDR)is a feasible approach to achieve precise gene replacement and base substitution in some plant species, the dominance of the non-homologous end joining pathway and low efficiency of HDR in plant cells have limited its application. Base editing has emerged as an alternative tool to HDR-mediated replacement, facilitating precise editing of plant genome by converting one single base to another in a programmable manner without a doublestranded break and a donor repair template. In this review, we summarize the latest developments in base-editing technologies as well as their underlying mechanisms. We review current applications of these technologies in plant species. Finally, we address the challenges and future perspectives of this emerging technology in plants. 展开更多

Soybean(Glycine max(L.) Merr.) is a non-native and non-staple crop in sub-Saharan Africa(SSA) with potential to be a commercial crop owing to its wide range of uses as food, feed,and industrial raw material. Soybean was first introduced to SSA by Chinese traders in the19 th century and was cultivated as an economic crop as early as 1903 in South Africa. In the past four decades, soybean cultivation area and production in SSA has increased exponentially, from about 20,000 ha and 13,000 t in the early 1970 s to 1,500,000 ha and2,300,000 t in 2016. Soybean yield has been stagnant in SSA for decades at about 1.1 t ha^(-1),much lower than the world average, representing one of the most challenging issues in the soybean industry in SSA. The low soybean yield in SSA can be attributed to the use of poorperforming varieties and to the limited application of fertilizers and rhizobial inoculants in soils with no history of soybean production. South Africa, Nigeria, Zambia, and Uganda are the leading soybean producers in SSA. Soybean research in SSA is conducted by international and national research institutions, including IITA, national soybean improvement programs, universities, and the private sector. Between 1970 and 2011, 195 soybean varieties were released by IITA, private breeders, and national soybean improvement programs in SSA. This paper reviews the history and current state of soybean production and of the utilization and adoption of tropical varieties in SSA, addresses the major soybean yield-limiting factors across the region, and discusses the potential of the soybean industry in SSA. It also highlights soybean improvement efforts and lessons learned from previous soybean improvement efforts and the current progress of some national soybean improvement programs in SSA. Opportunities for scaling up tropical soybean as a major crop across SSA countries are promising. 展开更多

Investment in agricultural capital construction is an important factor in improving China's agricultural productivity and international competitiveness. In recent years,the attention to the investment in agricultural capital construction has been lifted to a strategic height. However,there is still little research on the investment in agricultural capital construction. From the perspective of investment of different ministries and commissions,this paper systematically analyzed current situations,problems,and came up with recommendations for the investment in the agricultural capital construction. According to the results,( i) from 1983 to the present,China's investment in agricultural capital construction experienced three stages. Especially after 2010,the scale of investment in agricultural capital construction was huge,and it showed a rapid increasing trend;( ii) the investment in agricultural capital construction is characterized by " multi-sector investment,different departments having different investment priorities and investment scale in different periods";( iii) some investment projects are overlapping between departments,local areas are weak in providing support funds,project construction standard is single,and there are problems of attaching importance to the application,belittling the management,stressing the construction,belittling the maintenance,and serious brain drain;( iv) different departments have accumulated certain experience in long-term exploration. For example,they pay more attention to the refinement and differentiation of projects,focus on the development of targeted poverty alleviation,pay more attention to the " quality" of investment,and pay more attention to the transformation of agricultural production methods. Based on current situations and problems,it came up with recommendations including promoting the integration of funds for investment and project integration,strengthening the personnel cultivation,ensuring simultaneous construction and management of projects,stressing the maintenance after project construction,exploring new modes for project design,management,investment,and financing,and enhancing the support for special investment projects. 展开更多

Metabolic-associated fatty liver disease(MAFLD)is one of the most common chronic liver diseases worldwide.In recent years,the occurrence rate of MAFLD has been on the rise,mainly due to lifestyle changes,high-calorie diets,and imbalanced dietary structures,thereby posing a threat to human health and creating heavy social and economic burdens.With the development of 16S sequencing and integrated multi-omics analysis,the role of the gut microbiota(GM)and its metabolites in MAFLD has been further recognized.The GM plays a role in digestion,energy metabolism,vitamin synthesis,the prevention of pathogenic bacteria colonisation,and immunoregulation.The gut-liver axis is one of the vital links between the GM and the liver.Toxic substances in the intestine can enter the liver through the portal vascular system when the intestinal barrier is severely damaged.The liver also influences the GM in various ways,such as bile acid circulation.The gut-liver axis is essential in maintaining the body’s normal physiological state and plays a role in the onset and prognosis of many diseases,including MAFLD.This article reviews the status of the GM and MAFLD and summarizes the GM characteristics in MAFLD.The relationship between the GM and MAFLD is discussed in terms of bile acid circulation,energy metabolism,micronutrients,and signalling pathways.Current MAFLD treat ments targeting the GM are also listed. 展开更多
