A Clinical Study of Japanese Cedar (Cryptomeria japonica) Pollen-Induced Asthma [PDF]
Background: Grass and birch pollens are known to induce asthma. However there are few reports about other pollen-induced asthma. Japanese cedar is the most common allergen in rhinitis in Japan but is controversial on whether it can provoke asthma ...

Cryptomeria japonica: Japanese Cedar
The tree keeps a billowy pyramidal form on one central trunk until close to maturity when the crown opens up into an irregular, narrow oval. It will reach a height of about 50 feet and spread about 20 feet. Old specimens can develop trunks to three feet

Inferring the demographic history of Japanese cedar, Cryptomeria japonica, using amplicon sequencing. [PDF]
The evolution of a species depends on multiple forces, such as demography and natural selection. To understand the trajectory and driving forces of evolution of a target species, it is first necessary to uncover that species' population history, such as past and present population sizes, subdivision and gene flow, by using appropriate genetic markers ...

Japanese Cedar (Cryptomeria japonica) Pollinosis in Jeju, Korea: Is It Increasing? [PDF]
Jeju is an island in South Korea located in a temperate climate zone. The Japanese cedar tree (JC) has become the dominant tree species while used widely to provide a windbreak for the tangerine orchard industry. An increase in pollen counts precedes atopic sensitization to pollen and pollinosis, but JC pollinosis in Jeju has never been studied.
