Transferred the NP-1 gene into C. ellipsoidea by electroporation with high efficiency expression vector pBinUΩNP1. PCR, Southern blot and Northern dot blot analysis of the G418resistant alga strains indicated the stable integration and correct transcription of NP-1 in C. ellipsoidea genome. In vitro antagonistic assays showed the proper expression of defense gene in C. ellipsoidea. Transgenic C. ellipsoidea is antagonistic to gram negative bacteria—Bacillus subtonic, gram positive bacteria—Escherichiacoli and fungi—Fusarium oxysporum to some extent.
