Resumo: Realizou-se o levantamento de fungos associados a plantas invasoras na cultura do café instalada em experimento tipo FACE no Brasil cujo aparato, instalado em anéis de 10 m de diâmetro, mantém a concentração de CO2 a 200 ppm acima da concentração no ambiente. As avaliações de espécies com sintoma de doença foram realizadas aos 18, 55, 103, 129, 162 e 186 dias após o início da operação do FACE. Amostras de tecido vegetal foram coletadas e observadas em microscópio ótico e estereoscópico para identificação dos agentes causais através de chaves taxonômicas. Os resultados obtidos mostraram que a maioria das espécies invasoras e fungos associados ocorreram tanto nos tratamentos que recebem como nos que não recebem aplicação de CO2. O número máximo de espécies observadas foi de seis e a associação mais frequente, independente do tratamento foi a ocorrência do gênero Bipolaris em Brachiaria decumbens. |

Crop improvement efforts aiming at increasing crop production (quantity, quality) and adapting to climate change have been subject of active research over the past years. But, the question remains 'to what extent can breeding gains be achieved under a changing climate, at a pace sufficient to usefully contribute to climate adaptation, mitigation and food security?'. Here, we address this question by critically reviewing how model-based approaches can be used to assist breeding activities, with particular focus on all CGIAR (formerly the Consultative Group on International Agricultural Research but now known simply as CGIAR) breeding programs. Crop modeling can underpin breeding efforts in many different ways, including assessing genotypic adaptability and stability, characterizing and identifying target breeding environments, identifying tradeoffs among traits for such environments, and making predictions of the likely breeding value of the genotypes. Crop modeling science within the CGIAR has contributed to all of these. However, much progress remains to be done if modeling is to effectively contribute to more targeted and impactful breeding programs under changing climates. In a period in which CGIAR breeding programs are undergoing a major modernization process, crop modelers will need to be part of crop improvement teams, with a common understanding of breeding pipelines and model capabilities and limitations, and common data standards and protocols, to ensure they follow and deliver according to clearly defined breeding products. This will, in turn, enable more rapid and better-targeted crop modeling activities, thus directly contributing to accelerated and more impactful breeding efforts.
