CFo-III stoichiometry

[HOLLINGS at UBVMS.CC.BUFFALO.EDU]

Has there been any consensus reached at to the number of CFo-III
subunits found in the chloroplast proton-translocating ATP synthase/ATPase
complex?  I have references stating that there are five per complex and
other references that state there are eleven.

Thanks for your thoughts,
