1. Selection strategies in a segregating passion fruit population aided by classic and molecular techniques
ABSTRACT Combining the use of agronomic, disease-resistance, and molecular informationcan greatly contribute to genetic progress in breeding programs. This study was developed to estimate the genetic distance between genotypes derived from backcrosses and their parents using morphoagronomic and molecular information and information pertaining to resistance t

2. Genome composition and pollen viability of Jatropha (Euphorbiaceae) interspecific hybrids by Genomic In Situ Hybridization (GISH)
Abstract Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F1 and BC1F1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybrid

3. Comparative genome analysis of the SPL gene family reveals novel evolutionary features in maize
Abstract SPLs are plant-specific transcription factors that play important regulatory roles in plant growth and development. Systematic analysis of the SPL family has been performed in numerous plants, such as Arabidopsis, rice, and Populus. However, no comparative analysis has been performed across different species to examine evolutionary features. In this

4. New insights into genomic selection through population-based non-parametric prediction methods
ABSTRACT: Genome-wide selection (GWS) is based on a large number of markers widely distributed throughout the genome. Genome-wide selection provides for the estimation of the effect of each molecular marker on the phenotype, thereby allowing for the capture of all genes affecting the quantitative traits of interest. The main statistical tools applied to GWS

5. Triple categorical regression for genomic selection: application to cassava breeding
ABSTRACT: Genome-wide selection (GWS) is currently a technique of great importance in plant breeding, since it improves efficiency of genetic evaluations by increasing genetic gains. The process is based on genomic estimated breeding values (GEBVs) obtained through phenotypic and dense marker genomic information. In this context, GEBVs of N individuals are c

6. SNP markers associated with soybean partial resistance to Phytophthora sojae
Abstract Phytophthora root and stem rot is one of the most aggressive diseases in soybean crop. The use of resistant cultivars is the main strategy to reduce losses caused by the pathogen. This study aims to identify SNP markers associated with genes or QTLs that provide soybean with partial resistance to Phytophthora sojae. A total of 169 soybean cultivars

7. Heterologous Expression of a Putative ClpC Chaperone Gene Leads to Induction of a Host Metabolite
Genome mining provides exciting opportunities for the discovery of natural products. However, in contrast to traditional bioassay-guided approaches, challenges of genome mining include poor or no expression of biosynthetic gene clusters (BGCs). Additionally, given that thousands of BGCs are now available through extensive genome sequencing, how does one sele

8. PREDIÇÃO DE VALORES FENOTÍPICOS E GENOTÍPICOS VIA RR-BLUP/GWS E REDES NEURAIS
RESUMO A seleção genômica ampla (Genome Wide Selection - GWS) utiliza simultaneamente o efeito de milhares de marcadores cobrindo todo o genoma para predizer o valor genético genômico dos indivíduos no processo de seleção. Os possíveis benefícios de seu uso são a redução do ciclo de melhoramento, propiciando maior ganho por unidade de tempo e di

9. Linkage disequilibrium levels and allele frequency distribution in Blanco Orejinegro and Romosinuano Creole cattle using medium density SNP chip data
Abstract The linkage disequilibrium (LD) between molecular markers affects the accuracy of genome-wide association studies and genomic selection application. High-density genotyping platforms allow identifying the genotype of thousands of single nucleotide polymorphisms (SNPs) distributed throughout the animal genomes, which increases the resolution of LD ev

10. Quantity, organization, and distribution of chloroplast microsatellites in all species of Eucalyptus with available plastome sequence
Abstract In this study, we quantify and document the distribution and organization of cpSSRs in the chloroplast genome of 31 Eucalyptus species. Our sample included all previously sequenced plastomes of Eucalyptus species available from the NCBI online database. We processed the complete cpDNA sequences and identified mono-, di-, tri-, tetra-, penta-, and he

11. Characterization and expression of the ABC family (G group) in ‘Dangshansuli’ pear (Pyrus bretschneideri Rehd.) and its russet mutant
Abstract The plant genes encoding ABCGs that have been identified to date play a role in suberin formation in response to abiotic and biotic stress. In the present study, 80 ABCG genes were identified in ‘Dangshansuli’ Chinese white pear and designated as PbABCGs. Based on the structural characteristics and phylogenetic analysis, the PbABCG family genes

12. Improved reverse transcription-polymerase chain reaction assay for the detection of flaviviruses with semi-nested primers for discrimination between dengue virus serotypes and Zika virus
BACKGROUND The genus Flavivirus includes a variety of medically important viruses, including dengue virus (DENV) and Zika virus (ZIKV), which are most prevalent in Brazil. Because the clinical profile of patients affected by different DENV serotypes or ZIKV may be similar, the development of new methods that facilitate a rapid and accurate diagnosis is cru
