To investigate the potential of double-stranded RNA interferencing with gene expression in Dunaliella salina, a plasmid pBIRNAI-Dsa was constructed to express hairpin RNA (hpRNA) containing sequences homologous to phytoene desaturase gene (pds), a key gene in carotenoid biosynthesis, and transformed into D. salina by electroporation. The relative(More)
BACKGROUND Pyropia haitanensis and P. yezoensis are two economically important marine crops that are also considered to be research models to study the physiological ecology of intertidal seaweed communities, evolutionary biology of plastids, and the origins of sexual reproduction. This plastid genome information will facilitate study of breeding,(More)
By using in vitro PCR method, C-phycocyanin operon of Arthrospira platensis FACHB341 was cloned and characterized. The operon consists of 427 bp ussB, 519 bp cpcB gene, 111 bp igsB-A region, 489 bp cpcA gene, 184 bp ussH region and 357 bp cpcH gene. Promoter prediction and signal scan show that there are putative promoter sequences and regulatory elements(More)
Pyropia yezoensis is a model organism often used to investigate the mechanisms underlying stress tolerance in intertidal zones. The digital gene expression (DGE) approach was used to characterize a genome-wide comparative analysis of differentially expressed genes (DEGs) that influence the physiological, developmental or biochemical processes in samples(More)
The complete mitochondrial genome (mitogenome) of a red alga, Pyropia haitanensis Chang et Zheng, a circular-mapping molecule, was determined to be 37,023 bp. The overall AT content of the mitogenome is 69.32%. It contains 54 genes, including 49 conserved genes, 4 intronic reading frames, and an additional free-standing open reading frame. The rnl gene and(More)
Pyropia yezoensis Ueda, belonging to the Bangiales order Rhodophyte, is economically important seaweed distributed along the coastal region of the northwest Pacific. In this study, we report the complete mitochondrial DNA sequences of P. yezoensis. The entire genome comprised 41,688 bp with circular organization, which is the longest among the red algae(More)
The number of Circulating Tumor Cells (CTCs) in blood provides an indication of disease progression and tumor response to chemotherapeutic agents. Hence, routine detection and enumeration of CTCs in clinical blood samples have significant applications in early cancer diagnosis and treatment monitoring. In this paper, we investigate two classifiers for(More)
A generic pedestrian detector trained from generic datasets cannot solve all the varieties in different scenarios, thus its performance may not be as good as a scene-specific detector. In this paper, we propose a new approach to automatically train scene-specific pedestrian detectors based on track lets (chains of tracked samples). First, a generic(More)
BACKGROUND The seagrass Zostera marina is a monocotyledonous angiosperm belonging to a polyphyletic group of plants that can live submerged in marine habitats. Zostera marina L. is one of the most common seagrasses and is considered a cornerstone of marine plant molecular ecology research and comparative studies. However, the mechanisms underlying its(More)
The complete chloroplast genome of Gracilariopsis lemaneiformis was recovered from a Next Generation Sequencing data set. Without quadripartite structure, this chloroplast genome (183,013 bp, 27.40% GC content) contains 202 protein-coding genes, 34 tRNA genes, 3 rRNA genes, and 1 tmRNA gene. Synteny analysis showed plasmid incorporation regions in(More)
