Microsatellites are popular molecular markers in genetic and evolutionary studies. Their mutational dynamics have been extensively studied in humans and fruit flies, but few data were available in fish. By genotyping 55 individuals of a F1 pedigree, we investigated the mutation rates and patterns of 49 microsatellites in one of the most important fresh(More)
Parvalbumins are extremely abundant in fish muscle and play an important role in muscle relaxation. In this study, two parvalbumin genes (PVALB1 and PVALB2) were cloned from Asian seabass (Lates calcarifer). The cDNAs for PVALB1 and PVALB2 were 840 and 667 bp respectively. Both genes consisted of five exons and four introns, encoded 109 amino acids, and(More)
Quantitative trait loci (QTL) affecting growth traits have previously been mapped in linkage groups (LG) 2, 3 and 23 of Barramundi (Lates carcalifer), but these QTL have not been verified in different genetic backgrounds and environments. Here, we report the identification and verification of QTL for growth traits on LG2, 3, 10 and 23 in F(1) families(More)
We determined the complete mtDNA nucleotide sequence of Lates calcarifer using the shotgun sequencing method. The mitochondrial DNA (mtDNA) was 16,535 base pairs (bp) in length, and contained 13 protein coding genes, 22 transfer RNAs, 2 ribosomal RNAs, and one major noncoding control region (CR). The CR was unusually short at only 768 bp. A striking feature(More)
Microsatellites are useful markers for genetic mapping and linkage analysis because they are highly polymorphic, abundant in genomes and relatively easily scored with polymerase chain reaction (PCR). A rapid genotyping system for microsatellites was developed, which included multiplex PCRs, multiple use of Hydrolink gels, automated fluorescent detection of(More)
The caudal fin represents a fundamental design feature of fishes and plays an important role in locomotor dynamics in fishes. The shape of caudal is an important parameter in traditional systematics. However, little is known about genes involved in the development of different forms of caudal fins. This study was conducted to identify and map quantitative(More)
Ventricular myocytes from neonatal Wistar rats were cultured with 80% Dulbecoo's modified Eagle medium and 20% fetal bovine serum. An appropriate amount of xanthine and xanthine oxidase was added to the culture medium to increase the content of free radicals in cardiac cells. Variation in action potential and input impedance of cardiac myocytes indicated(More)
Fractal dimension (FD) has been proved useful in quantifying the complexity of dynamical signals in biology and medicine. In this study, we measured FDs of human electroencephalographic (EEG) signals at different levels of handgrip forces. EEG signals were recorded from five major motor-related cortical areas in eight normal healthy subjects. FDs were(More)
