Microsatellite-associated heterosis in hatchery-propagated stocks of the shrimp Penaeus stylirostris
Correlation between DNA microsatellite heterozygosity and growth rate was investigated in two hatchery-propagated stocks of the shrimp Penaeus stylirostris, which had been genetically isolated from wild founders for 17 generations, and from each other for five more generations. Presumed demographic history of these populations suggested that they were maintained at small effective population si...
متن کاملPersistence of Penaeus stylirostris densovirus delays mortality caused by white spot syndrome virus infection in black tiger shrimp (Penaeus monodon)
BACKGROUND Persistent infection of Penaeus stylirostris densovirus (PstDNV) (also called IHHNV) and its non-infectious inserts in the black tiger shrimp, Penaeus monodon (P. monodon) genome are commonly found without apparent disease. Here, we introduced the method of multiplex PCR in order to differentiate shrimp with viral inserts from ones with the infectious virus. The method allowed us to ...
متن کاملTranscriptional analysis of Penaeus stylirostris densovirus genes.
Penaeus stylirostris densovirus (PstDNV) genome contains three open reading frames (ORFs), left, middle, and right, which encode a non-structural (NS) protein, an unknown protein, and a capsid protein (CP), respectively. Transcription mapping revealed that P2, P11 and P61 promoters transcribe the left, middle and right ORFs. NS transcript uses the D1/A1 donor/acceptor sites for splicing and has...
متن کاملkuruma shrimp, Penaeus japonicus
A filamentous form of mollicute-like bacterium was detected during a routine health survey of wild adult kuruma shrimp Penaeus japonicus. The kuruma shrimp were native to Japan and were imported to Korea. The histology showed no pathological changes. Transmission electron microscopy revealed extensive infections of hepatopancreatic epithelial cells by a pleomorphic, filamentous intracellular ba...
متن کاملThe lipopolysaccharide and beta-1,3-glucan binding protein gene is upregulated in white spot virus-infected shrimp (Penaeus stylirostris).
Pattern recognition proteins such as lipopolysaccharide and beta-1,3-glucan binding protein (LGBP) play an important role in the innate immune response of crustaceans and insects. Random sequencing of cDNA clones from a hepatopancreas cDNA library of white spot virus (WSV)-infected shrimp provided a partial cDNA (PsEST-289) that showed similarity to the LGBP gene of crayfish and insects. Subseq...
