Simple sequence repeats (SSRs) are becoming a choice of markers in fish genetic research due to their abundance in the genome, co-dominant nature, high polymorphism and ability to reproduce. Thus, in this review, we have discussed regarding SSRs markers developed in fishes using different techniques. These markers have been used for revealing genetic(More)
Toll-like receptor 22 (TLR22) is present in teleost but not in mammals. Among Indian farmed carps, Catla catla is relatively more resistant than Labeo rohita to Argulus siamensis lice infection. TLR22 is believed to be associated with innate immunity against ectoparasite infection. To investigate the TLR22 mediated immunity against argulosis, we have cloned(More)
Because little is known about the function of Sox2 (Sry-related box-2) in teleosts, the objective of this study was to clone and characterize Sox2 complementary DNA (cDNA) from the testis of Indian major carp, Labeo rohita (rohu). The full-length cDNA contained an open reading frame of 936 nucleotides bearing the typical structural features.(More)
Recent advances in gene editing techniques have not been exploited in farmed fishes. We established a gene targeting technique, using the CRISPR/Cas9 system in Labeo rohita, a farmed carp (known as rohu). We demonstrated that donor DNA was integrated via homologous recombination (HR) at the site of targeted double-stranded nicks created by CRISPR/Cas9(More)
The myostatin (MSTN) is a known negative growth regulator of skeletal muscle. The mutated myostatin showed a double-muscular phenotype having a positive significance for the farmed animals. Consequently, adequate information is not available in the teleosts, including farmed rohu carp, Labeo rohita. In the absence of experimental evidence, computational(More)
The high-throughput sequencing technology provides a platform for revealing the expressed genes within a tissue at a specific time. The giant freshwater prawn, Macrobrachium rosenbergii, is an economically important species, which is surviving in a wide-range of salinity. In this study, to understand the physiological mechanism of adaptability with respect(More)
We previously characterized the β-actin gene promoter of Indian domesticated rohu carp (Labeo rohita) and made a reporter construct via fusion to green fluorescence protein (GFP) cDNA. In this study, the same construct was used to breed transgenic rohu fish. About 20% of the transgenic offspring showed ubiquitous expression of the reporter GFP gene. In a(More)
