Ixerides Japonicae

To others who have generously sent material of various species, and to the directors of the numerous botanical gardens who have generously sent seeds of many species, we also wish to express our gratitude. We are also much indebted to Mr. Ernest Jund for valuable assistance in growing the cultures and in making the cyto logical preparations, and to the Park Naturalist, Yosemite National Park, and his assistants for their generous cooperation in germinating the seeds of the more difficult species.

“…참취족에 속하는 참취속(Aster)에는 약 400여종이 주로 북반구에 분포하고 있으며 지리적 분포 에 따라 형태적 변이가 매우 다양한 것으로 알려져 있다 (Richard and Rieseberg, 1999). Kitamura(1937)는 한국, 중 국 및 일본 등 동아시아지역의 광의의 참취속 식물에 대한 연 구를 통해, 관모(pappus)의 길이에 근거하여 Kalimeris Cass., Heteropappus Less., Gymnaster Kitamura(syn. Miyamayomena Kitamura) 등 3개의 속으로 세분하였다.…”

This study was carried out to decide ITS (internal transcribed spacer) sequence of some Korean native Aster species and to resolve their relationship among Korean native Aster, including Kalimeris, Gymnaster, Heteropappus genus separated from Aster in a previously study based on the pappus length. We registered 11 ITS sequences of Aster species including A. glehni to GenBank and those sequences were used for the cluster analysis with Kalimeris species. The size of ITS1 was varied from 248 to 256 bp, while ITS2 was varied from 220 to 222 bp. The G + C content of the ITS region ranged from 49.4 to 53.5%. Pairwise comparison results showed that the substitution rate of ITS1 and ITS2 region was 9% and 10%, respectively. Kalimeris sensu strict substitution rate was lower than that of Aster sensu strict species. The strict consensus parsimonious cluster analysis showed A. tripolium is the first branching from the clade and the next is A. scaber. The Kalimeris species except for the A. hispidus were grouped into the same clade with high bootstrap value (91%) within Aster. Gymnaster and Heteropappus that has been classified by morphological characters were also grouped into broad sense Aster clade. These results implied these three genera could be merged together into Aster based on the ITS sequences.
