Abstract
Nitrogen-fixing bacterial isolate from the intercellular spaces of tom ato root cortical cells was studied for the location of nif genes on t he chromosomal or plasmid DNA. The bacterial isolate showed two plasmi ds of approximate molecular sizes of 220 and 120 kb. Klebsiella pneumo niae nif HDK probe hybridized with the chromosomal DNA and not with th e plasmid DNA thereby showing that nif genes are localised on the chro mosomal DNA.
