| 1 | Accumulation of carotenoids and expression of carotenoid biosynthesis genes in fruit flesh during fruit development in two Cucurbita maxima inbred lines显示文摘Mesocarp color is an important agronomic trait of Cucurbita maxima and is determined mainly by the contents and compositions of the carotenoids.The two inbred lines with significant differences in fruit flesh color were used in the study,the orange’312-1’and white’98-2’.Changes in seven carotenoid contents and compositions in the flesh of fruit produced by inbred lines’312-1’and’98-2’were analyzed during fruit development.The expression of eight key carotenoid biosynthesis genes in the fruit flesh were investigated during five fruit development stage in two inbred lines.As the flesh color intensified,the orange flesh color of’312-1’was determined mainly by the increased contents of lutein,β-carotene and zeaxanthin and the lack of carotenoid accumulation led to the formation of white flesh in’98-2’fruit.The expression of the LCY-e and CHYb genes was significantly stronger in’312-1’than in’98-2’,and their expression was strongly correlated with lutein andβ-carotene contents during fruit development.This study provides a deep understanding of the molecular mechanism of carotenoid biosynthesis in fruit flesh and provides a basis for additional studies on the highly refined improvement of squash quality. | Yusong Luo Chaojie Wang Manman Wang Yunli Wang Wenlong Xu Hongyu Han Zhichao Wang Yujuan Zhong Hexun Huang Shuping Qu | 2021 | Horticultural Plant Journal2021，7，6： | 3 |

| 4 | 外来入侵物种在青藏高原的入侵性和生态影响不一致显示文摘在全球变化背景下,管控入侵物种是一项具有挑战性的工作。这主要由于从入侵物种的入侵性推断它们的生态危害存在很大的不确定性。更确切地说,入侵性和生态危害的关系可能依赖于所研究的生态系统,同时这种关系还没有在像青藏高原这样独特的高寒生态系统中被研究过。在这项研究中,我们在青藏高原东南部的一个样带上调查了32种入侵植物。我们将这些入侵物种的生态危害分解为分布范围(R)、局部丰度(A)和个体对本地植物群落的影响(E)3个组分,并研究了植物性状对这些组分的相对贡献。研究结果表明,入侵植物的入侵性(R×A)和其所产生的危害(R×A×E)没有相关性。这表明这些入侵植物的入侵性不能反映它们对本地群落生态危害的严重性。在青藏高原,R和A共同驱动了入侵性,而R单独驱动了生态危害。植物性状并没有通过这3个组分驱动入侵性和生态危害,只有果实类型(主要是浆果)影响了E。我们的结果表明,驱动入侵性和生态危害的组分的不匹配导致了入侵植物的入侵性不能反映它们的生态危害。因此,关于入侵物种的管控应该优先考虑那些分布广泛的物种或者已经被证实会对本地物种产生负面影响的物种。 | Shuping Guan Pengdong Chen Xingle Qu Xiaolan Wang Shuopeng Wang Haiying Li Jiangping Fang Yi Wang Jiarui Chen Wei Huang Evan Siemann | 2023 | Journal of Plant Ecology2023，16，6： | 0 |
| 5 | The associations between the environmental exposure to polychlorinated biphenyls (PCBs) and breast cancer risk and progression显示文摘Polychlorinated biphenyls(PCBs) are chlorinated biphenyl compounds with wide applications in the industry.In spite of a ban on their production in the late 1970s,PCBs,as a group of POPs,are still persistent and widely spread in the environment,posing potential threats to human health.The role of PCBs as etiologic agents for breast cancer has been intensively explored in a variety of in vivo,animal and epidemiologic studies.Initial investigations indicated higher levels of PCBs in mammary tissues or sera corresponded to the occurrence of breast cancer,but later studies showed no positive association between PCB exposure and breast cancer development.More recent data suggested that the CYP1A1 m2 polymorphisms might add increased risk to the etiology of breast cancer in women with environmental exposure to PCBs.PCBs are implicated in advancing breast cancer progression,and our unpublished data reveals that PCBs activate the ROCK signaling to enhance breast cancer metastasis.Therefore,the correlation between PCB exposure and breast cancer risk warrants further careful investigations. | LIU SiJin ,ZHANG ShuPing,QU Chen,LIU Wei & DU YuGuo State Key Laboratory of Environmental Chemistry and Ecotoxicology Research Center for Eco-Environmental Sciences,Chinese Academy of Sciences,Beijing 100085,China | 2010 | Science China Chemistry2010，53，5： | 0 |
