| 2 | The Ulva prolifera genome reveals the mechanism of green tides显示文摘The genome of green microalgae has rarely been reported.Ulva prolifera is a green microalga that has received much attention.Despite research articles about U.prolifera in recent years,we know very little about its genome.Therefore,the 87.9-Mb haploid genome(containing 10311 protein-coding genes)of U.prolifera was studied,and the genome was compared with that of U.mutabilis,which is the only published Ulva species.Results showed that the two species are closely related.A phylogenetic tree was constructed among U.prolifera and other green algae available in GenBank,revealing the evolutionary status of U.prolifera in Chlorophyta.To understand why U.prolifera could grow rapidly,we identified some genes related to growth,such as those involved in cell division,phosphorylation,and cell proliferation.In addition,genes related to stress resistance were found,which supports the notion that U.prolifera grows vigorously in nature.These results help to characterize green tides from a new perspective and reveal some important insight into the biology of U.prolifera. | Yuan HE Songdong SHEN Dachun YU Yehua WANG Jiao YIN Zongling WANG Yuantu YE | 2021 | Journal of Oceanology and Limnology2021，39，4： | 1 |
| 3 | Effects of light and salinity on carotenoid biosynthesis in Ulva prolifera显示文摘Ulva prolifera is a green alga that plays an important role in green tides.Carotenoid biosynthesis is a basic terpenoid metabolism that is very important for maintaining normal life activities in algae.In this study,we first reported the complete sequences of all genes in the 2-C-methyl-D-erythritol 4-phosphate(MEP)pathway,which is the only carotenoid synthesis pathway in U.prolifera.Then,we compared these genes with those of other species.Additionally,by detecting the carotenoid contents and expression levels of key genes participating in carotenoid biosynthesis in U.prolifera under three different light(1000 lx,5000 lx and 12000 lx)and salinity(12,24 and 40)regimes,we found that carotenoid synthesis could be influenced by light and salinity,such that low light and high salinity could promote the synthesis of carotenoids.The results showed that the expression levels of genes involved in the MEP and the downstream pathway could affect the biosynthesis of carotenoids at the molecular level.This study contributes to a better understanding of the roles of genes participating in carotenoid biosynthesis in U.prolifera and the environmental regulation of these genes. | Yuan He Yuantu Ye Songdong Shen | 2020 | Acta Oceanologica Sinica2020，39，10： | 1 |
| 4 | Biological manipulation of eutrophication in West Yangchen Lake显示文摘This paper aims to share findings on nonclassical biomanipulation from a field study on eutrophic West Yangcheng(WY)Lake.In the forty years before 2009,cyanobacteria frequently bloomed in WY Lake,an event which has not occurred since 2009.The stocking density of filter-feeding carp was estimated to be more than 50 g/m^(3) in July after 2009,approximately double the amount observed before 2009,and the ratio of silver carp to bighead carp(SBR)increased from 0.8 to more than 1.6.Compared with the water quality between 2004 and 2007,the total nitrogen(TN)and the chlorophyll-a(Chl-a)concentration decreased while total phosphorus(TP)and transparency(SD)increased significantly after 2009(P<0.05).The decreasing Chl-a concentration was observed in Jul,Jun,May,Jul,and Mar in 2009,2010,2011,2016,and 2017,respectively.The Chl-a concentration was significantly negatively correlated with TP(P<0.05),and no significant correlation with TN was observed(P>0.05).A significant negative correlation was observed between fish yield and SD(P<0.05).The results also showed that filter-feeding carp more effectively restrained algae growth when SD was low.These results indicated that a high density of filter-feeding fish with increased SBR interfered with the driving effects of nutrients and temperature on the growth of algal biomass and then restrained bloom of algae.It may be necessary to take SD into consideration for determining the appropriate fish stocking density for the biomanipulation of algae. | Chunfang Cai Jie He Wen Chen Junbiao Zhang Qianqian Wang Xuehong Song Yuantu Ye Yongling Wang Ping Wu Xiamin Cao | 2019 | Aquaculture and Fisheries2019，4，5： | 0 |
