- Abstract
The rDNA ITS sequences from two populations in China were studied and three analog species were discussed together. The whole sequences of rDNA ITS regions (including ITS-1,5.8S and ITS-2) of Tremella aurantialba were reported first time. The results showed that little difference in length between the sequences was found and the length was 467bp and 468bp, respectively. Tremella aurantialba and Tremella aurantia formed a separate stable branch in the topology trees, while Tremella mesenterica clustered on another clade. The relationship between two populations of Tremella aurantialba in Yunnan and Shanxi provinces and Tremella aurantia is closely related, and they can replace each other as the same medicine according to the rDNA ITS. The character of ITS sequences can be used for providing the molecular markers for identifying Tremella aurantialba and exploring its genetic basis of fungal sources.
