ABSTRACT
The full-length cDNA of bystin isoform 1 (PmBys1) of the giant tiger shrimp Penaeus monodon was characterized. It was 1553â¯bp in length containing an ORF of 1365â¯bp corresponding to a polypeptide of 454 amino acids. The level of PmBys1 mRNA in ovaries was greater than that in other tissues of females and in testes of males in both juveniles and wild broodstock (Pâ¯<â¯.05). In non-ablated wild female broodstock, PmBys1 mRNA significantly and progressively increased in ovaries from stage I of development, peaking at stage IV (Pâ¯<â¯.05). Its level in stages I-IV of eyestalk-ablated broodstock was greater than that in non-ablated broodstock (Pâ¯<â¯.05). Injection of exogenous serotonin (50⯵g/g body weight) into 18-month-old shrimp resulted in a significantly increase of ovarian PmBys1 mRNA at 6-48â¯h post injection (hpi) (Pâ¯<â¯.05). PmBys1 protein (52â¯kDa) was found in ovarian stages I-V of non-ablated wild broodstock and II-IV of ablated wild broodstock, respectively. Along with the 52â¯kDa band, immunoreactive bands of 50 and 43â¯kDa were also observed in ovarian stages II-IV of both non-ablated and ablated broodstock and in ovaries of post-spawning broodstock. The 43 KDa band was not observed in ovarian stage I of wild female broodstock or in premature juveniles. PmBys1 protein was localized in the ooplasm of previtellogenic oocytes, nucleo-cytoplasmic compartments of vitellogenic oocytes and cortical rods of mature oocytes in wild broodstock. The results implied a possible role for PmBys1 during ovarian development in P. monodon.
