Molecular cloning and characterization of prophenoloxidase gene in swimming crab Portunus trituberculatus.
Phenoloxidase (PO), a melanin-synthesizing enzyme, found as a zymogen (proPO) in hemolymp, plays an important role in arthropod defence. In this study, a prophenoloxidase (proPO) cDNA was cloned from the haemocytes of swimming crab Portunus trituberculatus by a reverse-transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA end (RACE) method. Analysis of the nucleotide ...
متن کاملScreening of genes related to ovarian development in the swimming crab, Portunus trituberculatus, by suppression subtractive hybridization.
The swimming crab, Portunus trituberculatus, is an important marine animal and is widely cultured in China. In the present study, suppression subtractive hybridization was applied to identify the differentially expressed genes in the ovaries of mature and immature P. trituberculatus. One hundred and seventy six expressed sequence tag (ESTs) were identified, of which 100 were down-regulated, and...
متن کاملTranscriptome Analysis of Portunus trituberculatus in Response to Salinity Stress Provides Insights into the Molecular Basis of Osmoregulation
BACKGROUND The swimming crab, Portunus trituberculatus, which is naturally distributed in the coastal waters of Asia-Pacific countries, is an important farmed species in China. Salinity is one of the most important abiotic factors that influence not only the distribution and abundance of crustaceans, it is also an important factor for artificial propagation of the crab. To better understand the...
متن کاملFeeding ecology of blue swimming crab, Portunus segnis (Forskal, 1775) in Coastal waters of Chabahar, (Oman Sea)
Feeding habits of the blue swimming crab, Portunus segnis were studied in the coastal waters of Chabahar (Oman Sea) during the period from January 2015 to June 2015. The stomach contents of 623 crabs (included 138 males and 125 females) were analyzed. Their contents appeared to consist of mainly large quantities fish (48.2 %), crustaceans (19 %) and molluscs (15.7 %), also small quantities of s...
متن کاملReproductive biology of blue swimming crab, Portunus segnis (Forskal, 1775) in coastal waters of Persian Gulf and Oman Sea, Iran
A reproductive biology study of blue swimming crab, Portunus segnis (Forskal, 1775) in the northern Persian Gulf and Oman Sea, was conducted from May 2010 to October 2011. The results showed that the annual sex ratio is not M: F=1:1, with 51.9 % female. All the five stages of ovarian development of P. segnis were observed throughout the year. The size of ovigerous crabs varied from 103 to 155...
