Carotenoid content is the primary determinant of fruit color that affects nutritional value and appearance in tomato. Phytoene synthase (PSY) is the key regulatory enzyme in the carotenoid biosynthesis pathway. Absent function of PSY1 in tomato fruit results in yellow flesh phenotype. We, here, report that two different transcripts, a wild-type (Psy1) and a(More)
Diseases have been the bottle-neck to sustainable development of sturgeon cultivation. Bacterial septicemia that caused mass mortalities of sturgeons is still prevalent in Shanxi and Yunnan provinces in China. The epidemiology and pathogenicity of the disease were investigated. Four predominant isolates of bacteria were isolated from Siberian sturgeons(More)
The use of Bacillus probiotics has been demonstrated as a promising method in the biocontrol of bacterial diseases in aquaculture. However, the molecular antibacterial mechanism of Bacillus still remains unclear. In order to explore the antibacterial mechanism of the potential antagonistic Bacillus amyloliquefaciens strain G1, comparative proteomics between(More)
Saprolegnia species have been implicated for significant fungal infections of both living and dead fish as well as their eggs. In the present study, an oomycete water mould (strain HP) isolated from yellow catfish (Peleobagrus fulvidraco) eggs suffering from saprolegniosis was characterized both morphologically and from ITS sequence data. It was initially(More)
Recent studies have revealed that the use of probiotics is an alternative to control marine aeromonas. However, few probiotics are available against Aeromonas hydrophila infections in eels. In the present study, a potential antagonistic strain G1 against the eel-pathogenic A. hydrophila was isolated from sediment underlying brackish water. Its extracellular(More)
Recent studies have revealed that the use of bdellovibrios is an alternative to control bacteriosis. However, no bdellovibrios are available against Aeromonas hydrophila infections in sturgeons. In the present study, a potential Bdellovibrio strain F16 was isolated from sturgeon gut samples, using a sturgeon-pathogenic A. hydrophila as the prey bacterium.(More)
Vibriosis has become a major global economic problem in freshwater-farmed whiteleg shrimp (Penaeus vannamei). The prevention and control of vibriosis are now priority research topics. In this study, a pathogenic strain (QH) was isolated from vibriosis-infected freshwater-farmed P. vannamei that resulted in leg yellowing and was identified as a Vibrio(More)
Bacteriosis has become a major economic problem in the farming of the Pacific white shrimp Penaeus vannamei. However, no definitive data are available about Proteus penneri infection in cultured P. vannamei and its control. In this study, a virulent strain NC was isolated from diseased P. vannamei suffering from red body disease and identified as a P.(More)
