Paracoccus sp. Arc7-R13, a silver nanoparticles (AgNPs) synthesizing bacterium, was isolated from Arctic Ocean sediment. Here we describe the complete genome of Paracoccus sp. Arc7-R13. The complete genome contains 4,040,012?bp with 66.66?mol%?G?+?C content, including one circular chromosome of 3,231,929?bp (67.45?mol%?G?+?C content), and eight plasmids with length ranging from 24,536?bp to 199,685?bp. The genome contains 3835 protein-coding genes (CDSs), 49 tRNA genes, as well as 3 rRNA operons as 16S-23S-5S rRNA. Based on the gene annotation and Swiss-Prot analysis, a total of 15 genes belonging to 11 kinds, including silver exporting P-type ATPase (SilP), alkaline phosphatase, nitroreductase, thioredoxin reductase, NADPH dehydrogenase…
Ilyonectria mors-panacis is a serious disease hampering the production of Panax notoginseng, an important Chinese medicinal herb, widely used for its anti-inflammatory, anti-fatigue, hepato-protective, and coronary heart disease prevention effects. Here, we report the first Illumina-Pacbio hybrid sequenced draft genome assembly of I. mors-panacis strain G3B and its annotation. The availability of this genome sequence not only represents an important tool toward understanding the genetics behind the infection mechanism of I. mors-panacis strain G3B but also will help illuminate the complexities of the taxonomy of this species.
Nematode-trapping fungi (NTF) are a large and diverse group of fungi, which may switch from a saprotrophic to a predatory lifestyle if nematodes are present. Different fungi have developed different trapping devices, ranging from adhesive cells to constricting rings. After trapping, fungal hyphae penetrate the worm, secrete lytic enzymes and form a hyphal network inside the body. We sequenced the genome of Duddingtonia flagrans, a biotechnologically important NTF used to control nematode populations in fields. The 36.64 Mb genome encodes 9,927 putative proteins, among which are more than 638 predicted secreted proteins. Most secreted proteins are lytic enzymes, but more…
Populus alba is widely distributed and cultivated in Europe and Asia. This species has been used for diverse studies. In this study, we assembled a de novo genome sequence of P. alba var. pyramidalis (= P. bolleana) and confirmed its high transformation efficiency and short transformation time by experiments. Through a process of hybrid genome assembly, a total of 464 M of the genome was assembled. Annotation analyses predicted 37 901 protein-coding genes. This genome is highly collinear to that of P. trichocarpa, with most genes having orthologs in the two species. We found a marked expansion of gene families related to histone and the…
To better understand the immune system of shrimp, this study combined PacBio isoform sequencing (Iso-Seq) and Illumina paired-end short reads sequencing methods to discover full-length immune-related molecules of the Pacific white shrimp, Litopenaeus vannamei. A total of 72,648 nonredundant full-length transcripts (unigenes) were generated with an average length of 2545 bp from five main tissues, including the hepatopancreas, cardiac stomach, heart, muscle, and pyloric stomach. These unigenes exhibited a high annotation rate (62,164, 85.57%) when compared against NR, NT, Swiss-Prot, Pfam, GO, KEGG and COG databases. A total of 7544 putative long noncoding RNAs (lncRNAs) were detected and 1164 nonredundant…
