| 1 | Relationship between gene expression and the accumulation of catechin during spring and autumn in tea plants (Camellia sinensis L.)显示文摘The tea plant(Camellia sinensis L.)is an important commercial crop with remarkably high catechin concentrations.Tea is popular worldwide given the plant's health benefits.Catechins are the main astringent substance in tea and are synthesized mainly via the phenylpropanoid pathway.In this study,eight cultivars of tea plants harvested both in spring and autumn were used to investigate differences in catechin concentrations by using high-performance liquid chromatography.The expression levels of genes associated with catechin biosynthesis were investigated using reverse transcription-quantitative polymerase chain reaction.The results indicated that the total catechin(TC)concentrations were significantly higher in tea plants harvested in autumn than in those harvested in spring,based on higher concentrations of epigallocatechin(EGC)in autumn tea(P<0.01).The expression of the genes phenylalanine ammonia-lyase(PAL),flavanone 3-hydroxylase(F3H),flavonoid 3′,5′-hydroxylase(F3′5′H),dihydroflavonol 4-reductase(DFR),and anthocyanidin synthase(ANS)is closely related to the TC content of tea plants in both spring and autumn.Positive correlations between PAL,cinnamate 4-hydroxylase(C4H),F3H,and DFR expression and EGC accumulation in autumn tea were identified,with correlation coefficients of 0.710,0.763,0.884,and 0.707,respectively.A negative correlation between ANS expression level and EGC concentrations in tea plants harvested in spring was noted(r=−0.732).Additionally,negative correlations between F3H and ANS expression levels and the catechin content were identified in spring tea,whereas the correlations were positive in autumn tea.Significant differences in the F3H and ANS expression levels between spring and autumn tea indicate that F3H and ANS are potentially key genes affecting catechin accumulation in tea plants. | Min Liu Heng-lu Tian Jian-Hua Wu Ren-Rong Cang Run-Xian Wang Xiao-Hua Qi Qiang Xu Xue-Hao Chen | 2015 | Horticulture Research2015，2，1： | 10 |
| 2 | Research on power-supply cost of regional power system under carbon-peak target显示文摘With the establishment of the carbon-peak target by 2030,the direction of carbon emission reduction in China’s energy system has been further clarified.As the industry with the largest proportion of carbon emissions in China,the lowcarbon transformation of the electric power industry is critical to realize the carbon-peak target.Current research mostly focuses on technical analysis or system cost accounting of the carbon-peak realization path at the national level.There is a lack of targeted research on regional power systems with complex inter-regional power flow exchange and limited energy resource development.Simultaneously,the calculation of the system cost lacks the perspective of the life cycle and ignores the inertia of the stock and change inertia of incremental disturbance.From the perspective of the life cycle,this study proposes a calculation model of power supply cost for regional power systems according to the carbon-peak target,analyzes the realization path of the carbon target from an economic perspective,and provides references for the path selection and policy formulation of system transformation. | Jingyi Wang Min Cang Xiaomeng Zhai Shuang Wu Xi Cheng Lei Zhu | 2022 | Global Energy Interconnection2022，5，1： | 1 |
| 3 | Optimal scheduling of a township integrated-energy system using the adjustable heat-electricity ratio model显示文摘With the expansion and implementation of rural revitalization strategies,there is a constant need for new energy sources for the construction of new townships.Consequently,integrated energy systems with the interconnection and interaction of multiple energy sources are developing rapidly.Biomass energy,a renewable green energy source with low pollution and wide distribution,has significant application potential in integrated energy systems.Considering the application of biomass energy in townships,this study established an integrated biomass energy system and proposed a model to optimize its operation.Lowest economic cost and highest clean energy utilization rate were considered as the objective functions.In addition,a plan was suggested to adjust the heat-electricity ratio based on the characteristics of the combined heat and power of the biomass.Finally,a simulation analysis conducted for a town in China was discussed,demonstrating that the construction of a township integrated-energy system and the use of biomass can significantly reduce operating costs and improve the energy utilization rate.Moreover,by adjusting the heat-electricity ratio,the economic cost was further reduced by 6.70%,whereas the clean energy utilization rate was increased by 5.14%. | Quan Chen Jingyi Wang Min Cang Xiaomeng Zhai Xi Cheng Shuang Wu Dongwei Li | 2024 | Global Energy Interconnection2024，7，1： | 0 |
