Transferability Test of SSR Markers Developed from Allium sativum to other Allium Species

다국어 초록 (Multilingual Abstract)

The genus Allium which is one of the biggest plant genera comprises around 750 species that show the various morphological and ecological diversity with various taxonomic and geographical groups. The species of genus Allium has not been clearly distinguished because of extraordinary large amount of variation. We developed 8 simple sequence repeat markers (SSRs) which showed polymorphism within A. sativum accessions, but it was insufficient in transferability analysis of other Allium species. In this regard, we finally selected 50 primer pairs which was applicable to other Allium species adding to 8 primer pairs. According to results from application of 50 SSR markers to 9 Allium species, the average number of alleles ranged from 1.400 (A. porrum) to 1.889 (A. tuberrosum) and A. tuberosum (2n=32) has maximum 9 alleles. The lowest transferability value was 42.0% ( A. cepa and A. chinense) while A. sativum showed 96.7%. The A. porrum conceived to be close relationship to A. sativum as Allium subgenera revealed higher transferability (73%) rather than other Allium species. According to PCA analysis, three groups were divergent, and the A. fistulosum and A. sativum revealed the distinct groups and the rest 7 species formed another group.
