Development of EST-SSR Markers for Cultivar Determination and Genetic Diversity Studies of Commercial Chrysanthemums in the Korean Floral Market
Image Image Image Image Image
Fig. 1 The biplot result between the number of unigenes and their corresponding sizes as a result of de novo assembly using standard type chrysanthemum short read sequences of ‘Jung Woon’ and ‘Seino Isei’.
Fig. 2 Frequency of polymorphic SSRs by SSR types originating from chrysanthemum unigene sequences.
Fig. 3 Exemplary images of PCR amplification for 22 chrysanthemum SSR loci, which produce multiple bands (A, C, E) and single band like pattern (B, D, F), which include KNOU_CRYSSR1 (A), KNOU_CRYSSR7 (B), KNOU_CRYSSR8 (C), KNOU_CRYSSR31 (D), KNOU_CRYSSR23 (E) and KNOU_CRYSSR42 (F). The DNA template of each PCR reaction for lane 1 is Argus; lane 2, Borami; lane 3, Mujigae; lane 4, Yes Ruby; lane 5, Baekseol; lane6, Baekson; lane7, Zinba; lane8, Sumi. PCR amplification results of Six SSR loci out of 22 are shown as examples. The PCR amplicon of each SSR locus is separated by capillary electrophoresis system and visualized as a virtual gel image, obtained from PROSize software (v.2.0).
Fig. 4 The PIC estimation of the chrysanthemum SSR marker of our study. (A) The correlation of PIC estimation between 8 and 56 chrysanthemum cultivars among the 8 KNOU_SSR markers. The dataset is fitted to linear or polynomial regression model. The equation and R-square value of the linear and polynomial model are shown lower and upper part of the figure respectively. (B) The PIC estimation of KNOU_CrySSR40 with randomly selected 8, 24 and 40 cultivars from the 56 chrysanthemums. In the given number of cultivars which are randomly selected from the 56 chrysanthemums, the PIC values are estimated independently.
Fig. 5 A UPGMA dendrogram based on dissimilarity indices from 8 SSR markers as to 56 commercial chrysanthemum cultivars. Numbers below each branches refer to dissimilarity indices from UPGMA algorithm and the tree length is equivalent to dissimilarity index value. The scale bar is indicated in the left bottom. The dotted line on the left is the point where the populations are specified as denoted by different alphabets in the right. More info for the cultivars are listed in the Supplementary Table 1.
