13. 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.

14. Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Abstract Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 reco

15. Quantitative trait locus mapping associated with earliness and fruit weight in tomato
ABSTRACT The flowering time is regarded as an important factor that affects yield in various crops. In order to understand how the molecular basis controlling main components of earliness in tomato (Solanum lycopersicum L.), and to deduce whether the correlation between fruit weight, days to flowering and seed weight, is caused by pleiotropic effects or gene

16. Evaluation of SRAP markers for mapping of Pisum sativum L.
Abstract Linkage maps have become important tools for genetic studies. With the aim of evaluating the SRAP (sequence-related amplified polymorphism) technique for linkage mapping in Pisum sativum L., a F2 mapping population derived from an initial cross between cvs. DDR11 and Zav25 were generated. A total of 25 SRAP primer combinations were evaluated in 45 F

17. Characterization of the genetic environment of the bla KPC-2 gene among Klebsiella pneumoniae isolates from a Chinese Hospital
Abstract Infection caused by carbapenem-resistant Klebsiella pneumoniae has become a major healthcare threat and KPC-2 enzyme is a dominant factor mediating carbapenems resistance in K. pneumoniae. This study was designed to determine the genetic environment of bla KPC-2, which prevailed in clinical K. pneumoniae isolates recovered in Huashan Hospital, Shang

18. Developing a common bean core collection suitable for association mapping studies
Because of the continuous introduction of germplasm from abroad, some collections have a high number of accessions, making it difficult to explore the genetic variability present in a germplasm bank for conservation and breeding purposes. Therefore, the aim of this study was to quantify and analyze the structure of genetic variability among 500 common bean a

19. Development and validation of new SSR markers from expressed regions in the garlic genome
Only a limited number of simple sequence repeat (SSR) markers is available for the genome of garlic (Allium sativum L.) despite the fact that SSR markers have become one of the most preferred DNA marker systems. To develop new SSR markers for the garlic genome, garlic expressed sequence tags (ESTs) at the publicly available GarlicEST database were screened f

20. Characterization and mapping of a spotted leaf mutant in rice (Oryza sativa)
Spotted leaf mutant belongs to a class of mutants that can produce necrotic lesions spontaneously in plants without any attack by pathogens. These mutants have no beneficial effect on plant productivity but provide a unique opportunity to study programmed cell death in plant defense responses. A novel rice spotted leaf mutant (spl30) was isolated through low

21. Genetic structure of Argentinean hexaploid wheat germplasm
The identification of genetically homogeneous groups of individuals is an ancient issue in population genetics and in the case of crops like wheat, it can be valuable information for breeding programs, genetic mapping and germplasm resources. In this work we determined the genetic structure of a set of 102 Argentinean bread wheat (Triticum aestivum L.) elite

23. Desenvolvimento de um modelo para construção de mapas genéticos em autopoliploides, com aplicações em cana-de-açúcar / Development of a model to build genetic maps in autopolyploides, with applications in sugarcane
Autopolyploid species are extremely important in agriculture. However, the complex structure of their genomes is not well understood. Despite all advances in genetic mapping of autotetraploids, the vast majority of the models used for autopolyploid species with high ploidy level, such as sugarcane, are approximations of those used in diploid organisms. Thus,

24. Modelos mistos no mapeamento genético de fatores de risco cardiovascular em famílias brasileiras usando dados de SNPs / Mixed models in genetic mapping of the cardiovascular risk factors in brazilian families using SNPs data
O estudo de doenças complexas, tais como hipertensão e glicemia, é de grande importância na área médica, pois essas doenças afetam muitas pessoas no mundo e seu padrão de variação envolve componentes ambientais, genéticos e suas possíveis interações. Para o mapeamento de genes a amostragem do genoma humano é feita por meio de plataformas de ma
