Mycorrhizal fungi and N-Fixation

I gather that the nodules were cut open because I inquired about the interior
color and got an answer -- yellow. We have had a response from a worker in
India who is going to try to replicate the results. I have also received a
suggestion that some tomatoes form tubers, which is interesting all by itself.
The person who reported the results said that each of her tomato plants was of
a different variety, reducing in my view the significance that those more
distant from the beans did not have root swellings. I think we are going to
have to let this one ride unless we get some results from the folks in India.
The more information I have, the less likely it seems that we can conclude
anything from this report.

I've worked on rhizobia, N2-fixation, N-transfer by VAM from soil to the host,
and also with tomato but never have seen nodules on tomato except nematodes. I
suspect they may have actually observed root knot nematode on tomato and
confused it with rhizobia. Were x-sections made of the tissue or rhizobium
cultured from surface disinfected nodules? I'm skeptical also. Dr. Bob Ames.
