The sirtuin family of class III histone deacetylases (HDACs) is named after their homology to yeast silent information regulator 2 (SIR2). SIR2 and its mammalian derivatives (SIRT1-7) play a central role in gene silencing, cell cycle, aging and metabolism. Here we reported cDNA cloning, chromosome mapping,expression and evolutional analysis of sirtuin genes(More)
BACKGROUND The rice leaf folder (RLF), Cnaphalocrocis medinalis (Guenee) (Lepidoptera: Pyralidae), is one of the most destructive pests affecting rice in Asia. Although several studies have been performed on the ecological and physiological aspects of this species, the molecular mechanisms underlying its developmental regulation, behavior, and insecticide(More)
This paper describes a new species of chigger mite (ACARI: Trombiculidae), Gahrliepia cangshanensis n. sp., from rodents in southwest China. The specimens were collected from Yunnan red-backed voles, Eothenomys miletus (Thomas, 1914), and a Chinese white-bellied rat, Niviventer confucianus (Milne-Edwards, 1871) in Yunnan Province. The new species is unique(More)
Three bacterial strains, Arthrobacter sp. NB1, Serratia sp. NB2 and Stenotrophomonas sp. NB3, were isolated from contaminated sludge by using nitrobenzene as a sole source of carbon and nitrogen. It was observed that all three strains could degrade nitrobenzene at 400 mg/L initial concentration and mixed-cultivation of these strains could enhance the(More)
Blood-sucking lice (suborder Anoplura) parasitize eutherian mammals with 67% of the 540 described species found on rodents. The five species of blood-sucking lice that infest humans and pigs have fragmented mitochondrial genomes and differ substantially in the extent of fragmentation. To understand whether, or not, any life-history factors are linked to(More)
The suborder Anoplura contains 540 species of blood-sucking lice that parasitize over 840 species of eutherian mammals. Fragmented mitochondrial (mt) genomes have been found in the lice of humans, pigs, horses and rats from four families: Pediculidae, Pthiridae, Haematopinidae and Polyplacidae. These lice, eight species in total, are from the same major(More)
CREB3L4 (cAMP response element binding protein3 like 4) belongs to mammalian CREB/ATF subfamily transcription factors featuring a unique putative transmembrane domain lined to the bZIP region in their C-terminals. We report here the cloning of porcine CREB3L4 and its alternative splicing variant. The open reading frame of normal CREB3L4 covers 1,188 bp and(More)
The white-backed planthopper (WBPH), Sogatella furcifera (Horváth) is a serious pest causing grievous damage to rice plants. In the present study, inter-simple sequence repeats were employed to investigate the genetic diversity of 108 samples from 27 WBPH geographic populations in China. Ten primers were screened out with 147 amplified bands, average(More)
Chitinase is used to degrade chitin in insect cuticles and the peritrophic matrix. In this study, the full-length cDNA sequence of a Cht gene (SfCht7) was identified and characterized from the white-black planthopper, Sogatella furcifera. The SfCht7 cDNA was 3148bp, contained an open reading frame of 2877bp and encoded 958 amino acids with a predicted(More)
