Identification and characterization of a Penaeus monodon lymphoid cell-expressed receptor for the yellow head virus.
The yellow head virus is a positive-sense, single-stranded RNA virus that causes significant mortality in farmed penaeid shrimp. This study sought to isolate and characterize the receptor protein used by the virus to gain entry into Penaeus monodon Oka (lymphoid) organ cells, a primary target of yellow head virus infections. Virus overlay protein binding assay on Oka organ membrane preparations...
متن کاملDifferentially expressed genes in Penaeus monodon hemocytes following infection with yellow head virus.
A cDNA microarray composed of 2,028 different ESTs from two shrimp species, Penaeus monodon and Masupenaeus japonicus, was employed to identify yellow head virus (YHV)-responsive genes in hemocytes of P. monodon. A total of 105 differentially expressed genes were identified and grouped into five different clusters according to their expression patterns. One of these clusters, which comprised fi...
متن کاملA Circo-Like Virus Isolated from Penaeus monodon Shrimps
A virus with a circular Rep-encoding single-stranded DNA (ssDNA) (CRESS-DNA) genome (PmCV-1) was isolated from Penaeus monodon shrimps in Vietnam. The gene structure of the 1,777-nucleotide (nt) genome was similar to that of circoviruses and cycloviruses, but the nucleic acid and protein sequence identities to these viruses were very low.
متن کاملPenaeus monodon caspase is targeted by a white spot syndrome virus anti-apoptosis protein.
Caspases play a central and evolutionarily conserved role in mediating and executing apoptosis. Here, we report the cloning and characterization of a caspase from Penaeus monodon, Pm caspase. The full-length Pm caspase cDNA is 1386bp, encoding a polypeptide of 304 amino acids with a calculated molecular mass of 34.3kDa. BLASTP analysis against the NCBI nr database showed that Pm caspase is simi...
متن کاملGill-associated virus of Penaeus monodon prawns: an invertebrate virus with ORF1a and ORF1b genes related to arteri- and coronaviruses.
A 20089 nucleotide (nt) sequence was determined for the 5' end of the (+)-ssRNA genome of gill-associated virus (GAV), a yellow head-like virus infecting Penaeus monodon prawns. Clones were generated from a approximately 22 kb dsRNA purified from lymphoid organ total RNA of GAV-infected prawns. The region contains a single gene comprising two long overlapping open reading frames, ORF1a and ORF1...
