종의장거리산포는집단의확산과집단간개체의흐름에중요한역할을한다. 본연구는독도에서발견된식물을형태학적특징과핵및엽록체DNA의분자마커를이용하여종을식별한결과, 참빗살나무(노박덩굴과)로확인되었다. 얕은토양층과험준한지형등입지적으로열악한대양섬인독도에서목본의분포는의미있는결과이며, 향후외부유입종의지속적인모니터링이요구된다.

Paternal inheritance of plastid genome was confirmed by PCR-sequencing in the interspecific cross between Actinidia arguta and A. deliciosa. Both coding region and spacer region in the plastid DNA were PCR amplified, restriction digested, or sequenced. PC

Developmental changes of chlorophyll-protein complexes (CPs) and plastid membrane proteins in greening mung bean cotyledons and the effect of spermine thereon were examined by SDS-polyacrylamide gel electrophoresis. The changes in the amounts of CPs became larger with the progress of greening and light-harvesting chlorophyll a/b protein (LHCP) was the main CP in the early greening stage up to 48 h. As the greening proceeded, chlorophyll-protein of the photosystem I (CPI) accumulated. Application of spermine were effective in accumulating CPs of the thylakoid membrane in the early phase of greening. In the profiles of the plastid membrane proteins, quantitative and qualitative changes were observed with the onset of greening up to 72 h. 56 kD protein of major intensity was observed in all greened chloroplasts and 24 kD protein increased remarkablly in both control and spermine-treated cotyledons. The thylakoids from spermine-treated cotyledons showed higher amounts of thylakoid proteins as compared to the controls. The results suggest that spermine may play a role in the regulation of plastid development and stabilizes the membrane function during greening.
