| 1 | Influence of genotypes and environmental factors on leaf triterpenoid content and growth of Cyclocarya paliurus显示文摘Cyclocarya paliurus, an economically valuable tree species, has traditionally been used as a nutraceutical food or medicine in China. However, limited information is available on its genotype selection and cultivation under a wide range of environmental conditions for growth and targeted health-promoting substances. We studied the effects of genotype and environment, and their interaction on leaf triterpenoid content and tree growth for 12 genotypes of C. paliurus grown at four sites. We quantified the correlation between leaf triterpenoid accumulation and tree growth. The contents of cyclocaric acid B, cyclocarioside I, and arjunolic acid ranged from 0.06 to 3.89, 0 to 3.71, and 0.65 to 8.86 mg g^-1, respectively. Three individual triterpenoids were primarily influenced by genotype (variation ranged from 53.7 to 68.0%), while environment accounted for most of the variation in total triterpenoid content and tree growth (71.3–89.5%). Most tested environmental parameters were significantly correlated to total triterpenoid content, but not to the contents of the individual triterpenoids measured. Growth in tree height and diameter at breast height were significantly negatively correlated with total triterpenoid content but were non-significantly correlated with individual triterpenoid contents. We conclude that genotypic selection, manipulation of environmental conditions, and implementation of appropriate silvicultural operations would be important strategies for increasing the accumulation of health-promoting phytochemicals. | Bo Deng Shengzuo Fang Xulan Shang Xiangxiang Fu Wanxia Yang | 2019 | Journal of Forestry Research2019，30，3： | 7 |
| 2 | Natural variations in flavonoids and triterpenoids of Cyclocarya paliurus leaves显示文摘Cyclocarya paliurus is widely distributed in subtropical areas of China.Secondary metabolites in the leaves,including flavonoids and triterpenoids,provide protection against diseases such as hyperlipidemia,diabetes,hypertension,and hypoimmunity.In this study,343 C.paliurus leaves were collected from 32 distinct populations covering most of the main distribution,to deduce the response of flavonoids and triterpenoids to seven environmental factors.Principal component analysis was performed using seven flavonoid and six triterpenoid compounds.The results show that altitude,latitude,and longitude significantly contributed to variations in total flavonoid and triterpenoid contents.In addition,the interaction of these metabolites was extensively correlated with environment changes,and therefore should be considered during selection and cultivation. | Caowen Sun Xulan Shang Haifen Ding Yanni Cao Shengzuo Fang | 2021 | Journal of Forestry Research2021，32，2： | 6 |
| 3 | Variation of soil enzyme activity and microbial biomass in poplar plantations of different genotypes and stem spacings显示文摘To improve the productivity of poplar plantations, a field experiment of split-plot design with four tree spacings and three poplar clones was established, and four soil enzyme activities and microbial biomass were monitored in the trial.Soil enzyme activities, in most cases,were significantly higher in topsoil(0–10 cm) than in lower horizons(10–20 cm).Soil cellulase, catalase and protease activities during the growing season were higher than during the non-growing season, while invertase activity followed the opposite trend.Soil invertase, cellulase and catalase activities varied by poplar clone but soil protease activity did not.Cellulase and protease activities in the plantation at 5×5 m spacing were significantly higher than in the other spacings.The highest catalase activity was recorded at 6×6 m spacing.At the same planting density, invertase activity was greater in square spacings than in rectangular spacings.Soil microbial biomass was also significantly affected by seedling spacing and poplar clone.The mean soil MBC was significantly lower in topsoil than in the lower horizon, while MBN showed the opposite pattern.Significantly positive correlations were observed among soil cellulase, protease and catalase activities(p<0.01), whereas soil invertase activity was negatively and significantly correlated with cellulase, protease and catalase activities(p<0.01).Soil microbial biomass and enzyme activities were not correlated except for a significantly negative correlation between soil MBC and catalase activities.Variations in soil enzyme activity and microbial biomass in different poplar plantations suggest that genotype and planting spacing should be considered when modeling soil nutrient dynamics and managing for long-term site productivity. | Ye Li Liping Zhang Shengzuo Fang Ye Tian Jiao Guo | 2018 | Journal of Forestry Research2018，29，4： | 5 |

| 12 | Whole-genome Duplication Reshaped Adaptive Evolution in A Relict Plant Species,Cyclocarya paliurus显示文摘Cyclocarya paliurus is a relict plant species that survived the last glacial period and shows a population expansion recently.Its leaves have been traditionally used to treat obesity and diabetes with the well-known active ingredient cyclocaric acid B.Here,we presented three C.paliurus genomes from two diploids with different flower morphs and one haplotype-resolved tetraploid assembly.Comparative genomic analysis revealed two rounds of recent whole-genome duplication events and identified 691 genes with dosage effects that likely contribute to adaptive evolution through enhanced photosynthesis and increased accumulation of triterpenoids.Resequencing analysis of 45 C.paliurus individuals uncovered two bottlenecks,consistent with the known events of environmental changes,and many selectively swept genes involved in critical biological functions,including plant defense and secondary metabolite biosynthesis.We also proposed the biosynthesis pathway of cyclocaric acid B based on multi-omics data and identified key genes,in particular gibberellinrelated genes,associated with the heterodichogamy in C.paliurus species.Our study sheds light on evolutionary history of C.paliurus and provides genomic resources to study the medicinal herbs. | Yinquan Qu Xulan Shang Ziyan Zeng Yanhao Yu Guoliang Bian Wenling Wang Li Liu Li Tian Shengcheng Zhang Qian Wang Dejin Xie Xuequn Chen Zhenyang Liao Yibin Wang Jian Qin Wanxia Yang Caowen Sun Xiangxiang Fu Xingtan Zhang Shengzuo Fang | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 1 |
