13. SSR-based genetic analysis of sweet corn inbred lines using artificial neural networks
Abstract Studies on genetic diversity and population structure provide basic information at the molecular level, which is a key input for breeding programs of crop species. This study evaluated the genetic diversity of 12 elite lines of sweet corn, using 20 microsatellite markers. To determine the genetic differentiation among lines, we used an artificial ne

14. Agronomic and molecular characterization of wild germplasm Saccharum spontaneum for sugarcane and energycane breeding purposes
ABSTRACT: Among the species related to sugarcane, Saccharum spontaneum (L.) is a wild species with the greatest potential as a source of genetic variation to cope with biomass production in harsh environments. Due to its high yield, early vigor, ratooning ability, low input requirements and tolerance to various biotic and abiotic stresses, sugarcane breeders

15. DNA fingerprinting based on SSR amplification profiles for Piper species identification (Piperaceae)
ABSTRACT DNA fingerprinting based on SSR amplification profiles was applied to native species of Piper from the Atlantic Forest to compare the utility of this type of molecular marker with the morphological characters traditionally applied in Piper taxonomy and identification. Fifty-one SSR markers developed for four species of Piper native to Asia and Mesoa

16. Association between molecular markers and behavioral phenotypes in the immatures of a butterfly
Abstract Newly hatched caterpillars of the butterfly Heliconius erato phyllis routinely cannibalize eggs. In a manifestation of kin recognition they cannibalize sibling eggs less frequently than unrelated eggs. Previous work has estimated the heritability of kin recognition in H. erato phyllis to lie between 14 and 48%. It has furthermore been shown that the

17. Genetic diversity in Brazilian soybean germplasm
Abstract Genetic diversity is an essential factor for the success of any plant breeding program and should be considered to ensure genetic gain through breeding. In Brazil, research on the genetic diversity and population structure of soybean is required since the species is an important commodity of the country. The study addressed the genetic diversity and

18. A conventional PCR for differentiating common taeniid species of dogs based on in silico microsatellite analysis
ABSTRACT Canine taeniids are among the major tapeworms with remarkable medical and economic significance. Reliable diagnosis and differentiation of dog taeniids using simple and sensitive tools are of paramount importance for establishing an efficient surveillance system. Microsatellites as abundant unique tandem repeats of short DNA motifs are useful geneti

19. Evaluation of total flavonoid content and analysis of related EST-SSR in Chinese peanut germplasm
Abstract As important antioxidants and secondary metabolites in peanut seeds, flavonoids have great nutritive value. In this study, total flavonoid contents (TFC) were determined in seeds of 57 peanut accessions from the province of Hebei, China. A variation of 0.39 to 4.53 mg RT g-1 FW was found, and eight germplasm samples containing more than 3.5 mg RT g-

20. Genome-wide association study of pre-harvest sprouting resistance in Chinese wheat founder parents
Abstract Pre-harvest sprouting (PHS) is a major abiotic factor affecting grain weight and quality, and is caused by an early break in seed dormancy. Association mapping (AM) is used to detect correlations between phenotypes and genotypes based on linkage disequilibrium (LD) in wheat breeding programs. We evaluated seed dormancy in 80 Chinese wheat founder pa

21. Identification and validation of novel EST-SSR markers in olives
ABSTRACT: The olive (Olea europaea L.) is a leading oil crop in the Mediterranean area. Limited information on the inheritance of agronomic significant traits hinders progress in olive breeding programs, which encourages the development of markers linked to the traits. In this study, we report on the development of 46 olive simple sequence repeat (SSR) marke

22. The genetic diversity among strawberry breeding resources based on SSRs
ABSTRACT: Cultivated strawberry (Fragaria × ananassa Duch.) is a high value horticultural crop. In this study, the genetic diversity of 160 strawberry accessions was determined using five highly polymorphic simple sequence repeat (SSR) markers. Sixty different alleles were identified, with allele frequencies in the range of 0.006 to1. Similarity scores were

23. Mapping and allelic sequencing of a long sterile lemma trait in rice
ABSTRACT Some outer floral organs are unique in gramineous plants, like the sterile lemma and rudimentary glume in rice. However, their development mechanisms are still poorly understood. In this study, we used 4 mutants with long sterile lemma (LSL), named JF11, JF12, JF13 and JNY-7, to be crossed with Aijiaonante (AJNT) and Nipponbare (NIP), respectively.

24. Universal tail sequence-SSR applied to molecular characterization of tropical maize hybrids
ABSTRACT The development of efficient and low-cost genotyping methods is essential to precise genetic characterization of cultivars. Here, we present a system based on fluorescently labeled universal tail sequence primers (UTSP) to resolve microsatellite (SSR) markers as an alternative for molecular fingerprinting of maize. A set of 20 SSRs using the UTSP pr
