Thirty-six strains of endophytic Colletotrichum species were isolated from leaves of Bletilla ochracea Schltr. (Orchidaceae) collected from 5 sites in Guizhou, China. Seventeen different species, including 7 new species (namely C. bletillum, C. caudasporum, C. duyunensis, C. endophytum, C. excelsum-altitudum and C. guizhouensis and C. ochracea), 8(More)
The first doubled haploid (DH) population of Porphyra haitanensis was created by crossing a wild-type line with a red type, artificial pigmentation, mutant line, by means of single somatic cell clone cultivation. Six quantitative traits (frond length (FL), frond width (FW), frond thickness (FT), fresh weight (W), growth rate of frond length (LGR), and(More)
Investigation of the production and structural characteristics of the extracellular polysaccharides (ECPS) released by diatoms according to nutrient status is urgently necessary for our understanding of the roles of ECPS in aquatic ecosystem. In this study, the effects of N and P depletion and variable nutrient sources on the production and structural(More)
Investigation of how diatoms cope with the rapid fluctuations in iron bioavailability in marine environments may facilitate a better understanding of the mechanisms underlying their ecological success, in particular their ability to proliferate rapidly during favorable conditions. In this study, using in vivo biochemical markers and whole-cell iTRAQ-based(More)
Three new species of Phomopsis causing leaf spots on multiple hosts in Gutianshan Nature Reserve are characterized and illustrated. Phylogenetic analyses and morphological characteristics are employed to justify the introduction of the new species. The phylogenetic relationships of the three new species were inferred by analyses based on combined(More)
Brown tides caused by the excessive growth of the pelagophyte Aureococcus anophagefferens have occurred frequently in Qinhuangdao, China, since 2009. In this study, the temporal and spatial variations of A. anophagefferens and Minutocellus polymorphus were analyzed using real-time fluorescent quantitative PCR. The relationship between nutrient contents and(More)
Our initial RNA sequencing (RNA-seq) revealed that the Serum amyloid A1 (SAA1) gene was differentially expressed in the mammary glands of lactating Holstein cows with extremely high versus low phenotypic values of milk protein and fat percentage. To further validate the genetic effect and potential molecular mechanisms of SAA1 gene involved in regulating(More)
(2015) Characterizing the Interactions Among a Dinoflagellate, Flagellate and Bacteria in the Phycosphere of Alexandrium tamarense (Dinophyta). A small flagellate alga was isolated from the phycosphere of a toxic red tide dinoflagellate Alexandrium tamarense. Phylogenetic analysis and ultrastructural observations demonstrated that the small flagellate alga(More)
