We characterized 7 highly pathogenic avian influenza A(H5N1) viruses isolated from poultry in China during 2009-2012 and found that they belong to clade 2.3.4 but do not fit within the 3 defined subclades. Antigenic drift in subtype H5N1 variants may reduce the efficacy of vaccines designed to control these viruses in poultry.
We characterized two novel highly pathogenic H5N6 influenza viruses isolated from Chinese poultry in 2013. Genomic analysis showed that both isolates were reassortants, and derived their genes from H5 and H6 subtype viruses found in poultry in China. The virulence of the two isolates was examined in chickens and mice, and both isolates were found to be(More)
BACKGROUND Although extensive data demonstrates that the majority of H6 duck isolates belonged to a single H6N2 virus lineage with a single gene constellation in southern China from 2000 to 2005, the prevalence of H6N2 virus in poultry in Eastern China is largely unknown. RESULTS Epidemiology revealed that H6N2 viruses were the most frequently detected(More)
We address the problem of co-channel interference (CCI) in wireless mesh networks based on the IEEE802.11s extension. The carrier sensing mechanism deployed in those networks insufficiently addresses the CCI problem, causing the hidden and exposed node problems; consequently degrading the throughput and latency. In this paper, we show how beamforming(More)
One hundred and thirty-six bla OXA-51-negative strains were identified from 1,067 Acinetobacter calcoaceticus–A. baumannii complex (ACB complex) isolates, which were collected during October 2010 to March 2013 from 15 general hospitals in 10 cities throughout Zhejiang Province, China. Seven of the 136 bla OXA-51-negative ACB complex isolates were New Delhi(More)
The family of DNA binding with one finger (DOF) transcription factors is plant specific, and these proteins contain a highly conserved domain (DOF domain) of 50-52 amino acids that includes a C2C2-type zinc finger motif at the N-terminus that is known to function in a number of plant processes. Here, we characterized 20 DOF genes in the important ornamental(More)
Trihelix transcription factors are thought to feature a typical DNA-binding trihelix (helix-loop-helix-loop-helix) domain that binds specifically to the GT motif, a light-responsive DNA element. Members of the trihelix family are known to function in a number of processes in plants. Here, we characterize 20 trihelix family genes in the important ornamental(More)
The homeodomain-leucine zipper (HD-Zip) transcription factor family is a key transcription factor family and unique to the plant kingdom. It consists of a homeodomain and a leucine zipper that serve in combination as a dimerization motif. The family can be classified into four subfamilies, and these subfamilies participate in the development of hormones and(More)
