Streptomyces associated with root nodules ofCoriariain New Zealand

Abstract
Sections through root nodules of all seven species of Coriaria found in New Zealand showed the presence of a mycelial endophyte with hyphae less than 1 μ in diameter. These hyphae were embedded in the peripheral cytoplasm of infected cortical cells and produced numerous swollen branches which were radially arranged within the cell. The symbiotic association therefore differs anatomically from those described for other non-leguminous plants. Isolations from active nodules consistently yielded Streptomyces.
