Hybrids of Populus ciliata x maximowiczii are very vigorous and outperform both the parents in growth performance and yield. Genetic evaluation of 24 of these interspecific hybrids along with the two mother trees ( Populus ciliata), and five male-parent ( Populus maximowiczii) genotypes was carried out using the AFLP marker assay. Eight AFLP primer combinations detected 428 markers, of which 280 (66%) were polymorphic. Genetic relationships within the samples were evaluated by generating the similarity matrix based on Jaccard's coefficient. The phenetic dendrograms, as well as the PCO plots, separated the hybrids and the two parent species into three distinct clusters. The hybrids grouped closer to the P. ciliata (female parent) cluster as compared to the P. maximowiczii (male parent) cluster. The hybrid cluster contained internal groupings, which correlated to some extent with growth performance. The four best performing hybrids (42m1, 65m1, 23m2, Cm2-5-20/91) formed a distinct sub-cluster. Data from a single primer combination was sufficient for distinguishing the hybrids from the parents and assigning paternity. The hybrids showed 22 markers that were absent in P. ciliata but were monomorphically present in all the hybrids, suggesting outcrossing and common paternity. Further, these 22 markers were found in all the P. maximowiczii genotypes confirming it as the male parent. These male-specific markers can be converted to SCAR markers and used for rapid screening of the P.ciliata x maximowiczii hybrids. The primer combination E-AAC x M-CAA was identified as most suitable for ascertaining true hybridity. AFLP proves to be a useful tool for screening of P. ciliata x maximowiczii hybrids at the early stages of development.

Some Artemisia herbs are used for medicinal purposes. In particular, A. princeps and A. argyi are classified as 'Aeyup' and are used as important medicinal material in traditional Korean medicine. On the other hand, A. capillaris and A. iwayomogi, which are classified as 'Injinho' and 'Haninjin', respectively, are used for other purposes distinct from those of 'Aeyup'. However, sometimes 'Aeyup' is not clearly discriminated from 'Injinho' and/or 'Haninjin'. Furthermore, Artemisia capillaris and/or A. iwayomogi have been used in place of A. princeps and A. argyi. In this study, we developed an efficient method to discriminate A. argyi and A. princeps from other Artemisia plants. The RAPD (random amplified polymorphic DNA) method efficiently discriminated various Artemisia herbs. In particular, non-specific primer 329 (5'-GCG AAC CTC C-3'), which shows polymorphism among Artemisia herbs, amplified 838 bp products, which are specific to A. princeps and A. argyi only. Based on nucleotide sequence of the primer 329 product, we designed a Fb (5'-CAT CAA CCA TGG CTT ATC CT-3') and R7 (5'-GCG AAC CTC CCC ATT CCA-3') primer-set to amplify a 254 bp sized SCAR (sequence characterized amplified regions) marker, through which A. princeps and A. argyi can be efficiently discriminated from other Artemisia herbs, particularly, A. capillaris and A. iwayomogi.

Molecular sex identification is important in studying sex control, sex determination, and all-female breeding in half-smooth tongue sole (Cynoglossus semilaevis). In the present study, a female-specific AFLP marker was isolated from Cynoglossus semilaevis by AFLP technique using the selective primer combination E-ACT/M-CAA. This marker was re-amplified, recovered from the agarose gels, cloned and sequenced. Bioinformatic analysis indicated that the length of the product was 791 bp, and the sequence showed no similarity to any known sequences deposited in the GenBank database using BLASTn. According to the DNA sequence of the female-specific AFLP marker, specific PCR primers were designed and PCR amplification was performed on 100 sex-known individuals of C. semilaevis (50 females and 50 males each). A specific band 324 bp in length was present in all females but absent in all males (except for one male), indicating that the female-specific AFLP marker was successfully converted into female-specific SCAR (sequence characterized amplified regions) marker. The sex analysis of 3-day-old C. semilaevis individuals using this female-specific SCAR marker indicated that the female ratio was 41.7%. The female-specific SCAR marker developed in this study allowed simple, reliable, and rapid molecular sex identification using small amounts of fin tissue without sacrifice of C. semilaevis especially at early stage of development.
