[Study of the root nodules in some species of the Papilionaceae subfamily by scanning electron microscopy].
Nitrogen-fixing nodules from 16 species in 6 tribes of the sub-family Papilionaceae have been examined by scanning electron microscopy. The structure of infection threads was similar in all the studied papilionoid species except Lupinus polyphillus. In this species the infection threads were found in young nodules only. The morphology of bacterioids and the character of their "package" are determined by the host plant genotype. The obtained results are discussed in relation to the evolution of the legumes.
