Genetic diversity of symbiotic cyanobacteria in Cycas revoluta (Cycadaceae) [PDF]
FEMS Microbiology Ecology, 2012 The diversity of cyanobacterial species within the coralloid roots of an individual and populations of Cycas revoluta was investigated based on 16S rRNA gene sequences. Sixty-six coralloid roots were collected from nine natural populations of cycads on Kyushu and the Ryukyu Islands, covering the entire distribution range of the species.
