The use of resistant cultivars is the most effective strategy for controlling coffee leaf rust caused by the fungus Hemileia vastatrix. To assist the development of such cultivars, amplified fragment-length polymorphism (AFLP) markers linked to two loci of coffee resistance to races I and II as well as pathotype 001 of H. vastatrix were converted to sequence-characterized amplified region (SCAR) and cleaved amplified polymorphic site (CAPS) markers. In total, 2 SCAR markers and 1 CAPS marker were validated in resistant and susceptible parents as well as in 247 individuals from the F2 population. The efficiency of these markers for marker-assisted selection (MAS) was evaluated in F2:3 and backcross (BCrs2) populations genotyped with the developed markers and phenotyped with race II of H. vastatrix. The markers showed 90% efficiency in MAS. Therefore, the developed markers, together with molecular markers associated with other rust resistance genes, were used for F3:4 and BCrs3 coffee selection. The selected plants were analyzed using two markers associated with coffee berry disease (CBD) resistance, aiming for preventive breeding. MAS of F3:4 and BCrs3 individuals with all resistance loci was feasible. Our phenotypic and genotypic approaches are useful for the development of coffee genotypes with multiple genes conferring resistance to coffee leaf rust and CBD.

Fusarium wilt caused by Fusarium oxysporum f. sp. cubense (Foc) is one of the most destructive diseases in banana farming worldwide. Knowledge of the factors of genetic diversity and virulence of the pathogen contributes to the development of resistant cultivars and management strategies based on exclusion. In this study, phenotypic traits such as virulence and aggressiveness in a sample of 52 Foc isolates were analyzed and their relationship to the presence of putative effectors of gene SIX (Secreted in Xylem) pathogenicity homologs was verified. The similarity matrix revealed three isolates that were closest to the standard Foc race 1 strain. Isolates 229A and 218A were selected according to their aggressiveness profile in ‘Grand Naine’ and ‘Prata-Anã’, respectively, to replace the standard isolate of race 1 in the resistance screening process carried out by the breeding program. Two homologs of the SIX8 gene, SIX8a and SIX8b, are present in isolates of Foc from Brazil, and the SIX8b gene correlates with avirulence in the cultivar ‘Grand Naine’ (Cavendish). These results are important to support the banana genetic breeding program by identifying sources of resistance to Foc and contributing to the establishment of the function of SIX effector proteins.

Este trabalho teve como objetivo caracterizar molecularmente genótipos elite, e recomendados, de bananeira, por meio de marcadores RAPD e microssatélites. Foram utilizados 47 primers de RAPD e 34 primers de microssatélites. Foi também conduzido um ensaio de contaminação, utilizando-se o primer AGMI 24-25, cuja variedade Tropical foi considerada a amostra-padrão, e as cultivares Caipira e Prata Graúda como contaminantes. Os marcadores permitiram separar as cultivares de acordo com a origem e a constituição genômica e definiram padrões moleculares para algumas cultivares avaliadas. As cultivares Garantida, Preciosa e Pacovan Ken apresentaram alta similaridade genética com ambos marcadores. O primer AGMI 24-25 demonstrou alta capacidade discriminatória de genótipos em ensaios de contaminação.

O objetivo deste trabalho foi quantificar a variabilidade genética entre e dentro de populações de caroá (Neoglaziovia variegata), por meio de marcadores "random amplified polymorphic DNA" (RAPD). Foram analisados 180 genótipos de caroá, provenientes dos municípios de Guanambi, Juazeiro e Valente, no Estado da Bahia. Foi observado elevado polimorfismo entre as populações de caroá. As dissimilaridades genéticas entre os genótipos variaram de 0,08 a 0,95, com média de 0,44.Avariância molecular mostrou que 56% da variação total foi explicada pelas diferenças entre indivíduos dentro de locais. As diferenças entre municípios explicaram 17% da variação total, enquanto as diferenças entre locais dentro dos municípios explicaram 26% da variação.

A infertilidade masculina é caracterizada pela baixa produção de espermatozoides decorrente de diversos fatores, sendo um dos principais a varicocele, doença geralmente assintomática que possui relação negativa com a fertilidade do homem, por acarretar redução do volume testicular e diminuição da produção e qualidade espermática. Nestes casos deve-se realizar o exame físico por meio de palpação, e solicitar o espermograma do paciente. Pois sabe-se que a avaliação da qualidade seminal constitui um exame imprescindível para investigar as possíveis causas da infertilidade dos casais. Portanto, objetivou-se por meio deste artigo de revisão bibliográfica expor as causas e tratamento da varicocele e, compreender o seu potencial impacto sobre a fertilidade masculina. Para orientar esta revisão crítica de literatura, foram utilizados procedimentos de seleção de artigos e revisão bibliográfica baseados em meta-análises. A busca foi realizada em bases de dados como: Google Acadêmico e Scielo. Constatou-se que a varicocele é o achado clínico mais comum entre homens inférteis. O diagnóstico definitivo baseia-se na redução do volume testicular e/ou veias testiculares proeminentes. A detecção da doença e o tratamento rápido demonstra sucesso em mais de 90% dos casos. Conclui-se que a cirurgia de correção da varicocele é indicada como tratamento mais adequado, podendo melhorar a fertilidade.
