hi everybody..!

i am now doing a project abt transforming ornamental plants 
1)Anthurium 
2)Begonia

i using agrobacterium mediated transformation..
this bacteria had x-gluc (beta-glucuronidase gene) as a reporter gene..!
so i am doing Gus assay to detect the presence of the dis-armed T-DNA in 
the plant cell..!
however the ctrl explants which not infected with the bacteria have 
positive result for the GUS assay....
