Folk dance teaching has a far-reaching impact on inheriting the traditional folk culture and it also reflects the diversified school-running idea of higher education. Folk dance art is an art form that has been inherited for nearly a thousand years. In college dance teaching, teachers need to be fully aware of the profound significance of inheriting folk dance art and culture and recognize some problems in the process of inheriting folk dance culture in current college dance teaching in China, formulate scientific and reasonable infiltration strategies and strengthen students cognition of traditional folk dance culture in combination with local characteristics so as to give full play to the important task of inheriting traditional culture in colleges and universities and carry forward traditional folk dance culture.展开更多

The potential way to relieve this issue is to expand the donor pool via extending the donor criteria and make full use of all available grafts. The concept of “no-donor” liver transplantation allows grafts to be recovered from other liver recipients. This review summarizes the current clinical practice of “no-donor” liver transplantation, focusing on the experiences of Chinese transplant teams. Domino liver transplantation was introduced by Furtado in 1995 and implemented later in 2013 in China, and novel donor indications including some essential-to-treat inherited metabolic liver-based diseases have emerged. The concept of cross-auxiliary domino liver transplantation brings a further expansion of the domino liver graft pool, and the first pair of liver transplantation performed “rigorously without donation” was accomplished in our center in 2018. Our experience with this original transplantation procedure is hereby reviewed. In order to further promote and make successful “no-donor” liver transplantation, close co-operation between researchers, surgeons, physicians, organ procurement organizations, as well as ethical committees is required.展开更多

Using reciprocal cross, self-cross, and backcross, we have constructed various groups to seek the genetic law and mechanisms of tomato locule formation, for modifying the tomato breeding theory. The parental and the resulting FI and F2 generations have been used to examine the heredity of the locule number. The results showed that few-locule was incompletely dominant. The data from backcross demonstrated a significant effect on the locule number, whereas, the reciprocal cross showed an insignificant effect. Not surprisingly, the locule number was controlled by nuclear genomes, not by exogenous substances. The model that inherited the locule number belonged to the additive-dominant model： additive effects played a very important role and were partially dominant. In addition, the results revealed that the locule number in tomato was mainly controlled by a single gene, whereas, it was modulated by a number of other genes. Finally, the general inheritability and narrow inheritability of the locule number were 69.44% and 52.98%, respectively.展开更多

文摘Sugarcane is recognized as the fifth largest crop globally,supplying 80%of sugar and 40%of bioenergy production.However,sugarcane genetic research has significantly lagged behind other crops due to its complex genetic background,high ploidy(8-13×),aneuploidy,limited flowering,and a long growth cycle(more than one year).Cross breeding began in 1887 following the discovery that sugarcane seeds could germinate.Both self-and cross-pollination and selection were conducted by sugarcane breeders,but new cultivars were often eliminated due to disease susceptibility.Within the Saccharum genus,different species possess variable numbers of chromosomes.Wild sugarcane species intercrossed with each other,leading to development of the‘Nobilization’breeding strategy,which significantly improved yield,sucrose,fiber content,and disease resistance,and accelerated genetic improvement of cultivars.In recent years,scientific achievements have also been made in sugarcane genome sequencing,molecular marker development,genetic linkage map construction,localization of quantitative trait locus(QTL),and trait-associated gene identification.This review focuses on the progress in sugarcane genetic research,analyzes the technical difficulties faced,presents opportunities and challenges,and provides guidance and references for future sugarcane genetics research and cultivar breeding.Finally,it offers directions for future on sugarcane genetics.
文摘Inside a small shop on Lhasa's Barkhor Street,Namgyal Dorje,a young man born after 1995,delicately embeds copper wire across a wooden board.Although not born into a traditi onal Thangka pain ting family,Namgyal Dorje uses copper wire and enamel glaze to push the boundaries of traditional Thangka art-both in innovation and accessibility.

文摘Intergenerational inheritance of stress memory plays a crucial role in plant adaptation to environmental changes,particularly in the context of spaceflight,where plants may serve as a food source for humans on long-duration missions.However,the intergenerational genetic effects of spaceflight-induced stress memory in plants remain unclear.In this study,we assessed the cross-generational genetic effects of spaceflight stress memory using the rice mutant B10,identified during the SJ-10 return satellite mission.Our results showed that the oxidative stress effects induced by spaceflight persisted until the M5 generation in rice.We found that the rice genome remained unstable post-spaceflight,leading to alterations in genome methylation levels.Additionally,we observed significant changes in the methylation levels of transposons,suggesting their involvement in the intergenerational inheritance of spaceflight-induced stress memory.Furthermore,we identified thousands of differentially expressed genes(DEGs)and differentially alternatively spliced(DAS)genes induced by spaceflight stress memory across multiple rice generations.Notably,differentially methylated cytosines were more abundant in non-expressed genes than in DEGs or DAS genes.A substantial number of DEGs and DASs related to oxidative stress were identified,primarily involved in the generation and scavenging of reactive oxygen species.This study also presented report on the response of alternative splicing events in rice to spaceflight stress.Moreover,our findings revealed that genome methylation was associated with gene expression but not with DAS.In conclusion,our study provides comprehensive insights into the intergenerational inheritance of spaceflight-induced stress in rice and may contribute to uncovering novel mechanisms of oxidative stress-induced genomic instability and epigenetic regulation in plant stress inheritance.
文摘"Peaceful liberation,democratic reform,the establishment of the Autonomous Region...Every step of change occurred in Xizang has opened a window for cultural inheritance,"said Jorga,China’s first doctorate of Tibetan music,in an interview.His story embodies the sixty-year journey of Xizang’s ethnic music-from melodies once cherished deep within the plateau to a resonant voice now heard on the world stage.
