Advancements in genomics have dramatically accelerated the research on medicinal plants,and the development of herbgenomics has promoted the“Project of 1K Medicinal Plant Genome”to decipher their genetic code.However,it is difficult to obtain their high-quality whole genomes because of the prevalence of polyploidy and/or high genomic heterozygosity.Whole genomes of 123 medicinal plants were published until September 2022.These published genome sequences were investigated in this review,covering their classification,research teams,ploidy,medicinal functions,and sequencing strategies.More than 1,000 institutes or universities around the world and 50 countries are conducting research on medicinal plant genomes.Diploid species account for a majority of sequenced medicinal plants.The whole genomes of plants in the Poaceae family are the most studied.Almost 40%of the published papers studied species with tonifying,replenishing,and heat-cleaning medicinal effects.Medicinal plants are still in the process of domestication as compared with crops,thereby resulting in unclear genetic backgrounds and the lack of pure lines,thus making their genomes more difficult to complete.In addition,there is still no clear routine framework for a medicinal plant to obtain a high-quality whole genome.Herein,a clear and complete strategy has been originally proposed for creating a high-quality whole genome of medicinal plants.Moreover,whole genome-based biological studies of medicinal plants,including breeding and biosynthesis,were reviewed.We also advocate that a research platform of model medicinal plants should be established to promote the genomics research of medicinal plants.

The fundamental theory of traditional Chinese medicine and the consideration in its research strategy

Frontiers of Medicine 2011年第2期5卷 208-211页

作者： Zhenji Li Chunbo Xu World Federation of Chinese Medicine Societies Beijing 100101China

Stressing the uniqueness and complexity of traditional Chinese medicine(TCM)theory system,this paper analyzes the characteristics of TCM as a discipline from four perspectives:scientific nature,fundamental theory,clinical practice,and pharmacological action.It suggests that when the research strategy of TCM theory is designed,the core theory of TCM should be emphasized on the theoretical research on TCM original thinking theory,TCM theory,Chinese materia medica and formulas,acupuncture and moxibustion,meridians and collaterals,and other related fields.researchers and practitioners should ensure that the basic research on TCM theory is based on clinical practice,research methods(both traditional and contemporary)are exploited,and methodological innovation is underscored.The rule of TCM development should be followed and the characteristics and advantages of TCM carried forward.Meanwhile,the methods and theory of contemporary science and technology should be exploited to fulfill the goal of inheriting,enriching,and developing the fundamental theory of TCM.

Recent progress in research and design concepts for the characterization,testing,and photocatalysts for nitrogen reduction reaction

Carbon Energy 2023年第3期5卷 19-74页

The reduction of molecular nitrogen(N_(2))to ammonia(NH_(3))under mild conditions is one of the most promising studies in the energy field due to the important role of NH_(3)in modern industry,production,and life.The photocatalytic reduction of N_(2)is expected to achieve clean and sustainable NH_(3)production by using clean solar energy.To date,the new photocatalysts for photocatalytic reduction of N_(2)to NH_(3)at room temperature and atmospheric pressure have not been fully developed.The major challenge is to achieve high light-absorption efficiency,conversion efficiency,and stability of photocatalysts.Herein,the methods for measuring produced NH_(3)are compared,and the problems related to possible NH_(3)pollution in photocatalytic systems are mentioned to provide accurate ideas for measuring photocatalytic efficiency.The recent progress of nitrogen reduction reaction(NRR)photocatalysts at ambient temperature and pressure is summarized by introducing charge transfer,migration,and separation in photocatalytic NRR,which provides a guidance for the selection of future photocatalyst.More importantly,we introduce the latest research strategies of photocatalysts in detail,which can guide the preparation and design of photocatalysts with high NRR activity.

The Association between researchers’Conceptions of research and Their Strategic research Agendas

引用

Journal of Data and Information Science 2020年第4期5卷 56-74页

Purpose:In studies of the research process,the association between how researchers conceptualize research and their strategic research agendas has been largely overlooked.This study aims to address this gap.Design/methodology/approach:This study analyzes this relationship using a dataset of more than 8,500 researchers across all scientific fields and the globe.It studies the associations between the dimensions of two inventories:the Conceptions of research Inventory(CoRI)and the Multi-Dimensional research Agenda Inventory—Revised(MDRAI-R).Findings:The findings show a relatively strong association between researchers’conceptions of research and their research agendas.While all conceptions of research are positively related to scientific ambition,the findings are mixed regarding how the dimensions of the two inventories relate to one another,which is significant for those seeking to understand the knowledge production process better.research limitations:The study relies on self-reported data,which always carries a risk of response bias.Practical implications:The findings provide a greater understanding of the inner workings of knowledge processes and indicate that the two inventories,whether used individually or in combination,may provide complementary analytical perspectives to research performance indicators.They may thus offer important insights for managers of research environments regarding how to assess the research culture,beliefs,and conceptualizations of individual researchers and research teams when designing strategies to promote specific institutional research focuses and strategies.Originality/value:To the best of the authors’knowledge,this is the first study to associate research agendas and conceptions of research.It is based on a large sample of researchers working worldwide and in all fields of knowledge,which ensures that the findings have a reasonable degree of generalizability to the global population of researchers.
