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.

The regulation of gene expression is to have relations to the assembly of the DNA binding proteins which bind to DNA to initiate the transcription. Some of these proteins have the ability to promote bending or looping of DNA. The FIS protein regulates gene expression in Escherichia coli by this property of bending DNA. There are many researches to discover the mechanism of FIS protein binds to DNA. However the experiment data only show the supposititious results and figure out the model of FIS-DNA complex structure. This research uses molecular dynamics simulation to compute the detail of the interaction between FIS and DNA. We observed FIS prominently affects the DNA bending by the type of local bending. Analyzing the DNA structure properties, roll and slide, also demonstrates the local bending type and region. The hydrogen bonds between FIS and DNA are analyzed to compare with the experiment data. Finally we compute the binding free energy between FIS and DNA to estimate the result of simulation and compare with the value of λ-repressor-DNA complex.
