The present application relates to a kind of dsRNA of
prawn SGLT1
gene and its application.The target sequence of the dsRNA is derived from the coding sequence corresponding to the
transmembrane region outside loop,
intracellular loop or
extracellular loop of
sodium-dependent glucose
cotransporter SGLT1
gene coding
protein.The dsRNA of
prawn SGLT1
gene provides a new molecular means for preventing and controlling acute
hepatopancreas necrosis disease.The dsRNA molecule can be synthesized by
in vitro transcription or prokaryotic / eukaryotic expression
system, and can be further constructed to contain the sequence
expression cassette, recombinant vector and recombinant
bacteria.The dsRNA molecule of the present application is small in molecular weight, biodegradable, and will not cause environmental
pollution or
drug residue, with the advantages of safety,
environmental protection, high efficiency and scale production, etc., and can be used as a new
biological agent or
feed additive for preventing and controlling
Vibrio parahaemolyticus AHPND infection.
