1.Soybeanlectin reduced while peanut lectin increased the fluidity of fatty acyl chains and glycerol backbone, which was related with their hydrophobicity.
2.Results: trnL gene of chloroplast and lectin gene of soybean and zein 10 gene of maize were revealed positive by PCR when using DNAs extraction by modified CTAB method as templates, while lectin and zein 10 were revealed negative by PCR amplifying of several DNA samples prepared by SDS method.
3.Methods: DNAs of soybean, maize, tomato, potato and the processed products from these materials were extracted by using modified CTAB method or SDS method, and then were used as templates for PCR amplifying trnL gene of chloroplast as well as lectin gene of soybean and zein 10 gene of maize.
