We report a draft sequence for the genome of the domesticated silkworm (Bombyx mori), covering 90.9% of all known silkworm genes. Our estimated gene count is 18,510, which exceeds the 13,379 genes reported for Drosophila melanogaster. Comparative analyses to fruitfly, mosquito, spider, and butterfly reveal both similarities and differences in gene content.
Plant microRNAs (miRNAs) have been shown to play critical roles in regulating gene expression at the post-transcriptional level. In this study, we employed high throughput sequencing combined with computational analysis to survey miRNAomes from the seedlings of rice under normal conditions and treatments of H(2)O(2) that result in oxidative stress.(More)
Representing a basal branch of arachnids, scorpions are known as 'living fossils' that maintain an ancient anatomy and are adapted to have survived extreme climate changes. Here we report the genome sequence of Mesobuthus martensii, containing 32,016 protein-coding genes, the most among sequenced arthropods. Although M. martensii appears to evolve(More)
Two MdERFs (ethylene-response factors) were isolated from ripening apple (Malusxdomestica Borkh. cv. Golden Delicious) fruit. The features of their conserved motifs indicated that MdERF1 and MdERF2 belong to group VII and group IX categories in Arabidopsis, respectively. MdERF1 was expressed predominantly in ripening fruit, although a small degree of(More)
Cold-induced changes of gene expression and metabolism are critical for plants to survive freezing. Largely by changing gene expression, exposure to a period of non-freezing low temperatures increases plant tolerance to freezing-a phenomenon known as cold acclimation. Cold also induces rapid metabolic changes, which provide instant protection before(More)
Microsporidia are a group of intracellular parasites with an extremely compact genome and there is no confirmed evidence that retroelements are parasitised in these organisms. Using the dataset of 200,000 genomic shotgun reads of the silkworm pebrine Nosema bombycis, we have identified the eight complete N. bombycis long-terminal repeat retrotransposon(More)
Herpes simplex virus type 1 (HSV-1) is a widespread human pathogen that causes severe diseases, but there are not effective and safe drugs in clinical therapy besides acyclovir (ACV) and related nucleoside analogs. In this study, two new venom peptides from the scorpion Heterometrus petersii were identified with effective inhibitory effect on HSV-1(More)
Adsorptions of congo red and direct red 80 onto activated carbon/surfactant from aqueous solution were optimized. The Box-Behnken design (BBD) has been employed to analyze the effects of concentration of surfactant, temperature, pH, and initial concentration of the dye in the adsorption capacity. Their corresponding experimental data could be evaluated(More)
TaGW2-6A, cloned in earlier research, strongly influences wheat grain width and TKW. Here, we mainly analyzed haplotypes of TaGW2-6B and their effects on TKW and interaction with haplotypes at TaGW2-6A. About 2.9 kb of the promoter sequences of TaGW2-6B and TaGW2-6D were cloned in 34 bread wheat cultivars. Eleven SNPs were detected in the promoter region of(More)
Mulberry is an important cultivated plant that has received the attention of biologists interested in sericulture and plant-insect interaction. Morus notabilis, a wild mulberry species with a minimal chromosome number is an ideal material for whole-genome sequencing and assembly. The genome and transcriptome of M. notabilis were sequenced and analyzed. In(More)
