Construction of plant expression vector of Pseudopleuronectes americanus antifreeze protein gene

TL;DRAbstract

The Pseudopleuronectes americanus antifreeze protein gene was synthesized and control sequences were added such as 35S promoter and nos terminator that can facilitate the transcription and fi sequence and Kozak sequence that can improve the expression in translation level, the high expression cassette of antifreeze protein was constructed. This cassette was connected to pBI121.1 and finally got the high expression vector pBRTSAFP introduced into the maize callus. The expression of gus gene that linked to the antifreeze protein gene was detected, and the results was that the gus gene can express strongly and instantaneously.
