I see two or possibly 3 types of cell/organism in the image. I took the liberty of editing the original to mark cell types A,B,C. Which cells are you unsure of? I would agree that some appear to be storage cells as stated by Mr. Baumann. This would be the cell labeled A in my edited version. As to the other cells I am unsure and B and C could possibly be the same cell type just at different fields of depth. I would almost like to say it resembles a nematode but I dont see some details one might expect. A possible alternative would be an Oomycete of some form.

Partha Pratim Dhar

Dear David and Baumann, Thank you for your comment. Would you please send me any literature of Baumann? I think it is a new dimension. Regards

Thomas W. Baumann

Dear Partha

I am rather an expert of 'caffeine plants' than of maize. Nevertheless I refer you to the studies of Viktor B Ivanov dealing with the maize root. Here one link and the title of one of his articles:

Doklady Biological Sciences Volume: 245 Issue: 1-6 Pages: 766-768 Published: 1979

Unfortunately, I do not have access to his publications published in Russian journals.

Here his email-address (I hope he is still alive!):

I believe that H.-W. Dehne-Prof.Dr.agr.Dr.rer.hort.habil.

Can you help with identification .

Thank you all very much for your valuable suggestions. I tried in different literature and found similar structures inside the roots. They are mentioned to be DSE sclerotia (Dark Septate Endophytic sclerotia). These are Fungal organisms.
