We report a draft sequence for the genome of domesticated silkworm (Bombyx mori), covering 90.9% all known genes. Our estimated gene count is 18,510, which exceeds 13,379 genes reported Drosophila melanogaster. Comparative analyses to fruitfly, mosquito, spider, and butterfly reveal both similarities differences in content.
The silkworm, Bombyx mori L. (Lepidoptera: Bombycidae), an oligophagous insect that mainly feeds on mulberry leaves, is susceptible to entomopathogen infection when reared with tricuspid cudrania leaves. A total of 56 dominant bacterial strains, classified into 12 phylotypes based bacteriological properties and analysis 16S rRNA genes, were isolated from the intestine fourth fifth instar silkworm larvae. Ten seven exist in larvae leaves respectively. Four them are common two treatment...
To investigate whether Bombyx mori Linnaeus (Lepidoptera: Bombycidae) intestinal microorganism play a role in the host defence system against viral pathogens, lipase gene from silkworm bacterium Bacillus pumilus SW41 was characterized, and antiviral activity of its protein B. nucleopolyhedrovirus (BmNPV) tested. The has an open-reading frame 648 bp, which encodes 215-amino-acid enzyme with 34-amino-acid signal peptide. recombinant (without peptide) expressed purified by using Escherichia...
Dengue virus (DENV) causes a wide range of diseases in humans, from the acute febrile illness dengue fever (DF) to life-threatening haemorrhagic fever/dengue shock syndrome. We developed four real-time quantitative PCR assays for each serotype DENV based on computational analysis. These had high sensitivity and specificity without cross-reactivity serotypes. To evaluate performance these detecting typing clinical samples, we analysed 64 serum samples Guangdong during 2006. The results showed...
Enterocytozoon hepatopenaei, a spore-forming and obligate intracellular microsporidium, mainly infects shrimp results in growth retardation body length variation, causing huge economic losses to the Asian aquaculture industry. However, lack of full understanding surface proteins spores associated with host infection has hindered development technologies for detection EHP. In this study, EHP were extracted using improved SDS method, 130 identified via LC-MS/MS analysis. Bioinformatic analysis...
Triploid and pentaploid breeding is of great importance in agricultural production, but it not always easy to obtain double ploidy parents. However, fishes, chromosome diversiform, which may provide natural parental resources for triploid breeding. Both tetraploid hexaploid exist Schizothorax were thought belong different subfamilies with Percocypris fishes morphology, they are sister genera molecule. Fortunately, the hybrid have been successfully obtained by hybridization wangchiachii (♀,...
Plant surface is colonised with a vast community of non-pathogenic epiphytic microorganisms which play an important role in host defence. In the present study, we reported fungus from mulberry leaf that showed antagonistic effect against powdery mildew fungal pathogen Phyllactinia sp. This novel isolate yeast-like was identified as Pseudozyma aphidis CNm2012 based on morphologic and phylogenetic analysis. According to our research, P. directly acted conidia via parasitism caused conidial...
Abstract The occurrence of an epidemic outbreak a powdery mildew disease on mulberry in Yunnan province, China, is reported. Its symptoms are characteristic for mildews and visible as white pathches covering the abaxial surfaces leaves leading to chlorosis necrosis. pathogen morphologically barely distinguishable from Phyllactinia moricola . However, it exhibits several new morphological characteristics which 2–3 conidia could be formed short chains at apex conidiophores produce two germ...
Serratia marcescens is a common bacterium well-known for the red secondary metabolite prodigiosin. However, color mutants have long been described. Non-pigmented strains can be found to exist both naturally and under laboratory conditions. It unclear why S. loses prodigiosin synthesis capacity in certain In present study, we find that spontaneous arise within few generations (about five passages) rapidly replace wild-type parent cells 24 passages), which indicates growth advantage of former....
Serratia marcescens SCQ1 is a red-pigmented bacterium isolated from silkworm larva with septicemia. Pigment-deficient spontaneous mutants arise when S. incubated under relatively stable laboratory conditions for long time. Here, we present the complete genome sequence of and resequenced genomes four pigment mutants.
