Finger millet (Eleusine coracana L. Gaertn.) is an important cereal crop in eastern Africa and southern India with excellent grain storage capacity and the unique ability to thrive in extreme environmental conditions. In this study, we analyzed the genetic diversity and population structure of finger millet using 12 developed microsatellites. By sequencing 815 clones from an SSR-enriched genomic DNA library, we obtained 12 polymorphic SSR markers, which also revealed successful amplicons in finger millet accessions. Using the developed SSR markers, we estimated genetic diversity and population structure among 76 finger millet accessions in Asia, Africa, and unknown origins. The number of alleles ranged from 2 to 9, with an average of 3.3 alleles. The mean values of observed heterozygosity and expected heterozygosity were 0.27 and 0.35, respectively. The average polymorphism information content was 0.301 in all 76 finger millet accessions. AMOVA analysis showed that the percentage of molecular variance among the populations was 1%, that among individuals was 5%, and that within individuals was 94%. In STRUCTURE analysis, the 76 finger millet accessions were divided into two subpopulations which had an admixture of alleles. There was a correspondence among PCoA, AMOVA, and population structure. This study may form the basis for a finger millet breeding and improvement program.

Chemical Constitutions and Antioxidant Activities of Tomato Leaf Extracts
Kyung Jun Lee, Gi-An Lee, Kyung-Ho Ma, Sebastin Raveendar, Yang-Hee Cho, Jung-Ro Lee, Jong-Wook Chung
Plant Breed. Biotech. 2016;4(3):362-372.   Published online August 31, 2016

The present study aimed to determine the contents of five flavonols and two glycoalkaloids as well as the antioxidant activities of leaf ethanol extracts of 50 tomato accessions. The antioxidant activity was assessed using different tests: 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), 2,2-diphenyl-1-picryl hydrazyl (DPPH), nitric oxide (NO), and total polyphenol content (TPC). Flavonols and glycoalkaloids contents were determined using a high performance liquid chromatography-diode array detector system. Among five flavonols and two glycoalkaloids, naringenin and tomatine were detected in tomato leaves at high concentrations. Of the 50 tomato accessions, IT 229711, IT2365203, and IT 207224 were found to have the highest contents of quercetin, kaempferol, and tomatine, respectively. Leaf extract of IT189949 exhibited the highest relative antioxidant capacity index (RACI). Among the five flavonols, myricetin showed positive correlations with DPPH, ABTS, and NO, while isorhamnetin had positive correlation with DPPH. These results will expand the chemical constitution database and provide information on tomato leaves. They are valuable for the development of functional foods or feed-additives.

Genetic Diversity and Population Structure of Rubus Accessions Using Simple Sequence Repeat Markers
Kyung Jun Lee, Gi-An Lee, Hee-Kyoung Kang, Jung-Ro Lee, Sebastin Raveendar, Myoung-Jae Shin, Yang-Hee Cho, Kyung-Ho Ma
Plant Breed. Biotech. 2016;4(3):345-351.   Published online August 31, 2016

Sixty-nine Rubus accessions were analyzed to determine the genetic relationships using simple sequence repeat (SSR) markers. Twenty-three SSR markers generated a total of 351 alleles from all accessions, with an average of 15.3 alleles per locus. The average value of polymorphism information content was 0.76, ranging from 0.52 to 0.91. As a result of population structure analysis, 69 Rubus accessions of six Rubus species were subdivided into six subpopulations. Four subpopulations included distinct Rubus species accessions; pop2 (Rubus crataegifolius var. subcuneatus, 2 accessions), pop3 (R. crataegifolius Bunge., 18 accessions), pop4 (R. fruticosus L., 3 accessions) and pop6 (R. coreanus Miq., 36 accessions) while The pop1 and pop5 mainly included R. idaeus L. and R. parvifolius L., respectively. In cluster analysis, 69 Rubus accessions were divided into three groups. Group I contained 35 Rubus accessions, which consisted of six Rubus species. Groups II and III had 30 and 4 Rubus accessions, respectively. They consisted of only R. coreanus. The uncertain diversity of species and artificial groups of the Rubus genus has created confusion with respect to the correct classification of the species at both commercial and scientific levels. The results of the present study will provide basic information for phylogeny, taxonomy and breeding programs of Rubus species.

Genetic Diversity and Population Structure of Asian Tomato Accessions Based on Simple-Sequence Repeats
Sebastin Raveendar, Jong-Wook Chung, Gi-An Lee, Jung-Ro Lee, Kyung-Jun Lee, Myoung-Jae Shin, Yang-Hee Cho, Kyung-Ho Ma
Plant Breed. Biotech. 2016;4(3):306-314.   Published online August 31, 2016

Tomato (Solanum lycopersicum L.) is one of the most economically important plants in the family Solanaceae. Understanding its genetic diversity of accessions is vital for additional collection of tomato germplasms. The
objective
of this study was to determine the genetic diversity and population structure of 355 tomato accessions from Asia using 18 simple-sequence repeats (SSRs). A total of 176 alleles were detected at an average of ten alleles per SSR locus. The average major allele frequency and polymorphic information content were 0.69 and 0.39, respectively. Model-based structure analysis revealed two subpopulations (88%), including admixtures (11%) in the 355 Asian tomato accessions, consistent with clustering results based on genetic distance. The overall FST value was 0.135, indicating a moderate differentiation between the inferred subpopulations. Analysis of molecular variance showed that the genetic variance among geographical groups was less than 6%, in contrast to 86% of genetic variance among individuals. The results from this study will provide important information for future germplasm conservation and improvement programs for tomato.

Genetic Diversity Among Korean Rice Landraces (Oryza sativa L.) Based on Characters and SSR Markers
Kyung Jun Lee, Jong-Ro Lee, Gi-An Lee, Ho Sun Lee, Soon Ik Kwon, Yong-Gu Cho, Yang-Hee Cho, Kyung-Ho Ma, Sok-Young Lee, Jong-Wook Chung
Plant Breed. Biotech. 2015;3(3):216-225.   Published online September 30, 2015
DOI: https://doi.org/10.9787/PBB.2015.3.3.216

In order to estimate genetic diversity of Korean rice landraces, rice characters and SSR markers of 76 rice germplasms were analyzed. Of 12 rice characters, amylose content (AC) showed as largest variance (4.9 to 28.9%), whereas grain length (GL) showed as the lowest variance (4.4 to 5.9 mm). In principal component analyses (PCA), the first principal component explained 60.3% of total variance, in which culm length (CL) and growth period (GP) showed as positive variance and AC showed as negative variance. The second principal component explained an additional 22.4% of the total variance, in which GP and AC showed highly positive variables and CL showed a negative variable. Forty nine SSR markers produced a total of 473 alleles with an average of 9.65 alleles. Polymorphism information content (PIC) was in the range of 0.11 to 0.93. Average observed heterozygosity ranged from 0.12 to 0.39, with an average value of 0.61. As a result of STRUCTURE analysis, 76 Korean rice landraces showed two subpopulations. In clustering analysis, rice characters and SSR markers were clustered into four groups and three groups, respectively. However, they were not significant different from each other. These results provided insight into the characteristics of Korean rice landraces, thus improving our knowledge on rice breeding.
