| 2 | Some comments on general research methodology显示文摘Dear editors,The methodological introduction on family medicine and community health research1 provides general practitioners(GPs)with a good guide on general research method-ology,principles,procedures and examples.All of these have laid a good foundation for the development of general medical research in China.However,considering the actual situation,GPs still have some difficulties in applying these research methods. | Lingping Zhu | 2019 | Family Medicine and Community Health2019，7，3： | 0 |
| 3 | Characterization of Rheum palmatum mitochondrial genome and comparative analysis among Caryophyllales species显示文摘Objective:This work aimed to report the first complete mitochondrial genome(mitogenome)of Rheum palmatum,summarize the features of Caryophyllales mitogenomes,and to reveal the potential of utilizing the mitogenomes of R.palmatum and other Caryophyllales species for inferring phylogenetic relationships and species identification.Methods:Both Illumina short reads and PacBio HiFi reads were utilized to obtain a complete mitogenome of R.palmatum.A variety of bioinformatics tools were employed to characterize the R.palmatum mitogenome,compare the reported mitogenomes in Caryophyllales and conduct phylogenetic analysis.Results:The mitogenome of R.palmatum was assembled into a single master circle of 302,993 bp,encoding 35 known protein-coding genes,18 transfer RNA genes,and three ribosome RNA genes.A total of 249 long repeats and 49 simple sequence repeats were identified in this mitogenome.The sizes of mitogenomes in Caryophyllales varied from 253 kb to 11.3 Mb.Among them,23 mitogenomes were circular molecules,one was linear,and one consisted of relaxed circles,linear molecules,and supercoiled DNA.Out of the total mitogenomes,11 were single-chromosome structure,whereas the remaining 14 were multi-chromosomal organizations.The phylogenetic analysis is consistent with both the Engler system(1964)and the Angiosperm Phylogeny Group III system.Conclusions:We obtained the first mitogenome of R.palmatum,which consists of a master circle.Mitogenomes in Caryophyllales have variable genome sizes and structures even within the same species.Circular molecules are still the dominant pattern in Caryophyllales.Single-chromosome mitogenomes account for nearly a half of all the mitogenomes in Caryophyllales,in contrast to previous studies.It is feasible to utilize mitochondrial genomes for inferring phylogenetic relationships and conducting species identification. | Longlong Gao Lijun Hao Wenjie Xu Tianyi Xin Chi Song Yulin Lin Lingping Zhu Jingyuan Song | 2023 | Acupuncture and Herbal Medicine2023，3，4： | 0 |
| 4 | Tetraketide α-pyrone reductases in sporopollenin synthesis pathway in Gerbera hybrida:diversification of the minor function显示文摘The structurally robust biopolymer sporopollenin is the major constituent of the exine layer of pollen wall and plays a vital role in plant reproductive success.The sporopollenin precursors are synthesized through an ancient polyketide biosynthetic pathway consisting of a series of anther-specific enzymes that are widely present in all land plant lineages.Tetraketideα-pyrone reductase 1(TKPR1)and TKPR2 are two reductases catalyzing the final reduction of the carbonyl group of the polyketide synthase-synthesized tetraketide intermediates to hydroxylatedα-pyrone compounds,important precursors of sporopollenin.In contrast to the functional conservation of many sporopollenin biosynthesis associated genes confirmed in diverse plant species,TKPR2’s role has been addressed only in Arabidopsis,where it plays a minor role in sporopollenin biosynthesis.We identified in gerbera two non-anther-specific orthologues of AtTKPR2,Gerbera reductase 1(GRED1)and GRED2.Their dramatically expanded expression pattern implies involvement in pathways outside of the sporopollenin pathway.In this study,we show that GRED1 and GRED2 are still involved in sporopollenin biosynthesis with a similar secondary role as AtTKPR2 in Arabidopsis.We further show that this secondary role does not relate to the promoter of the gene,AtTKPR2 cannot rescue pollen development in Arabidopsis even when controlled by the AtTKPR1 promoter.We also identified the gerbera orthologue of AtTKPR1,GTKPR1,and characterized its crucial role in gerbera pollen development.GTKPR1 is the predominant TKPR in gerbera pollen wall formation,in contrast to the minor roles GRED1 and GRED2.GTKPR1 is in fact an excellent target for engineering male-sterile gerbera cultivars in horticultural plant breeding. | Lingping Zhu Teng Zhang Teemu H.Teeri | 2021 | Horticulture Research2021，8，1： | 0 |
