13. Growth, phenology, and seed viability between glyphosate-resistant and glyphosate-susceptible hary fleabane
ABSTRACT Glyphosate is the herbicide most used worldwide. In cropping systems that rely on repeated applications of glyphosate or cultivate genetically modified soyabean crop, there are numerous cases of glyphosate resistant weeds, including Conyza bonariensis. Differences among competitive ability of Conyza spp. have been found. However, little information

14. Genome-wide analysis of EgEVE_1, a transcriptionally active endogenous viral element associated to small RNAs in Eucalyptus genomes
Abstract Endogenous viral elements (EVEs) are the result of heritable horizontal gene transfer from viruses to hosts. In the last years, several EVE integration events were reported in plants by the exponential availability of sequenced genomes. Eucalyptus grandis is a forest tree species with a sequenced genome that is poorly studied in terms of evolution a

15. New biotechnological tools to accelerate scab-resistance trait transfer to apple
Abstract Apple is a fruit crop cultivated worldwide. Apple orchards are exposed to a diverse set of environmental and biological factors that affect the productivity and sustainability of the culture. Many of the efforts and costs for apple production rely on reducing the incidence of fungal diseases, and one of the main diseases is apple scab caused by the

16. Increasing the resistance of common bean to white mold through recurrent selection
ABSTRACT White mold, caused by Sclerotinea sclerotiorum (Lib.) de Bary is one of the most important diseases of the common bean (Phaseolus vulgaris L.) worldwide. Physiological resistance and traits related to disease avoidance such as architecture contribute to field resistance. The aim of this study was to verify the efficiency of recurrent selection in ph

17. Classification of physiological races of Fusarium oxysporum f. sp. phaseoli in common bean
Fusarium wilt, caused by Fusarium oxysporum Schlecht. f. phaseoli Kendrick and Snyder (FOP), is a major disease of common bean, causing large economic losses. Genetic resistance is one of the main mechanisms of pathogen control, and knowledge of the physiological variability is fundamental in breeding for resistant cultivars. Thus, a method of pathogen class

18. Propuesta de descriptores para Acca sellowiana (Berg.) Burret
The feijoa plants [Acca sellowiana (Berg.) Burret] is one of the most valued genetic resource plants underutilized from Uruguay and Brazil. This tree is endemic of a narrow area of South America, comprising the northeast of Uruguay and the south of Brazil. Beyond the fact that it has edible fruits, cultivation is limited to domestic scale or small orchards.

19. Large-scale analysis of NBS domain-encoding resistance gene analogs in Triticeae
Proteins containing nucleotide binding sites (NBS) encoded by plant resistance genes play an important role in the response of plants to a wide array of pathogens. In this paper, an in silico search was conducted in order to identify and characterize members of NBS-encoding gene family in the tribe of Triticeae. A final dataset of 199 sequences was obtained

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. A Química na agricultura: perspectivas para o desenvolvimento de tecnologias sustentáveis
Food production and preservation of the environment are among the challenges faced by contemporary society. In Brazil, as in most parts of the world, the possibility of increasing the agricultural area is limited by several factors. Thus, an increase in productivity through the application of innovative technologies is regarded as the best solution to overco

22. Epistasia na herança da resistência do milho ao gorgulho Sitophilus zeamais (Coleoptera: Curculionidae) / Epistasis in the inheritance of maize resistance to Sitophilus zeamais (Coleoptera: Curculionidae)
Considerado um dos aspectos mais complexos da genética quantitativa, a epistasia tem sido ignorada pelos melhoristas nos estudos de herança dos caracteres, principalmente os da herança da resistência de plantas a insetos, que são de difícil obtenção. No milho, a principal praga de grãos é o Sitophilus zeamais (Coleoptera: Curculionidae), devido a s

23. Avaliação de plantas transgênicas de laranja doce (Citrus sinensis) e transformação genética de laranja azeda (Citrus aurantium) para resistência ao Citrus tristeza virus (CTV) / Evaluation of sweet orange (Citrus sinensis) transgenic plants and genetic transformation of sour orange (Citrus aurantium) for the resistance to Citrus tristeza virus (CTV)
Citrus tristeza virus (CTV) ocorre em quase todas as áreas produtoras de citros do mundo. O controle da doença se baseia, principalmente, no uso de porta-enxertos tolerantes e na premunização das copas. A obtenção de copas de laranjas doces ou de porta-enxerto de laranja azeda transgênicos resistentes ao CTV permitiria retornar a um uso mais intensivo

Estabelecimento de um patossistema modelo e análise da interação molecular planta-patógeno entre Eucalyptus grandis e Puccinia psidii Winter por meio da técnica de RNA-Seq. / Establishment of a model pathosystem and analysis of the molecular plant-pathogen interaction between Eucalyptus grandis and Puccinia psidii Winter
More than 20 million hectares are destined to Eucalyptus plantations worldwide and Brazil has the second largest planted area. The International Eucalyptus Genome Network, EUCAGEN, was created in 2007 in order to perform genomic research on Eucalyptus. Brazil provided the biological material from the model tree (Brasuz) to have the complete genome sequenced
