Genetic diversity of symbiotic cyanobacteria in Cycas revoluta (Cycadaceae) [PDF]
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.

Is Cycas revoluta (Cycadaceae) wind‐ or insect‐pollinated? [PDF]
Among the Cycadales (Cycadaceae and Zamiaceae), the Zamiaceae are known to be insect‐pollinated. In contrast, the Cycadaceae are still considered wind‐pollinated, although some doubt has been cast on several species, including Cycas revoluta. Using a large population of C. revoluta on Yonaguni Island (Okinawa, Japan), we performed exclusion experiments,
