Actin is a highly conserved protein that is found in all eukaryotic cells, and has been widely used as an internal control gene in gene expression studies. In this study, we cloned an actin gene (named Ecβ-actin) from Exopalaemon carinicauda and determined its expression levels. The full-length cDNA of Ecβ-actin was 1335 bp long, comprising a 1131-bp ORF encoding 376 amino acids, a 65-bp 5'-UTR, and a 139-bp 3'-UTR with a poly(A) tail.

Analysis of ITS1 sequences and genetic relationships between populations of ridgetail white prawn, Exopalaemon carinicauda, in the East China Sea

X. Z. Zhang, Cheng, X. Q., Yu, Y. X., Shen, H., and Wan, X. H., “Analysis of ITS1 sequences and genetic relationships between populations of ridgetail white prawn, Exopalaemon carinicauda, in the East China Sea”, vol. 14, pp. 12316-12322, 2015.

Internal transcribed spacer 1 (ITS1) sequences from wild-type Exopalaemon carinicauda (N = 124) from the East China Sea were amplified and sequenced. Sequences were polymorphic and ranged from 388 to 583 bp in length. The average content of GC in sequences was significantly higher than that of AT. Altogether, 604 mutant sites with 123 haplotypes were detected; 46.7% were polymorphic sites. The genetic diversity index of population Y was highest, and the lowest was population X.

Isolation and characterization of polymorphic microsatellite loci in the ridgetail white prawn Exopalaemon carinicauda

S. W. Jia, Liu, P., Li, J., Li, J. T., and Pan, L. Q., “Isolation and characterization of polymorphic microsatellite loci in the ridgetail white prawn Exopalaemon carinicauda”, vol. 12, pp. 2816-2820, 2013.

The ridgetail white prawn Exopalaemon carinicauda is one of the major economic shrimp species cultured in China. In this study, 30 microsatellite loci were isolated and characterized for the ridgetail white prawn E. carinicauda using a microsatellite-enriched library. Polymorphisms were tested in 30 individuals from a single wild population. The number of alleles at each locus ranged from 2 to 14. The observed and expected heterozygosities varied from 0.1000 to 0.8000 and from 0.2299 to 0.9228, respectively. The PIC value ranged from 0.2002 to 0.8939.
