Mycorrhizal association contributes to plant growth, influencing tolerance to abiotic stresses such as water deficit. There is considerable variation in infection by arbuscular mycorrhizal fungi (AMF) in cultivars of the same crop, but there is little information regarding these differences in wheat. The objective of this work was to evaluate the influence of water deficit on the arbuscular mycorrhizal association in wheat genotypes in the Cerrado region and the association between soil attributes and mycorrhizal colonization. The experiment was conducted in a no-till system, using different water regimes. The experimental design was a randomized block with subdivided plots scheme, with 12 treatments and 3 repetitions. The plots consisted of 4 wheat genotypes and the subplots included 3 water regimes. Mycorrhizal colonization, soil microbial biomass carbon, total soil organic carbon, easily extractable glomalin-related soil protein, spore number and AMF species diversity were evaluated. Mycorrhizal colonization was not influenced by wheat genotypes, but it was favored by the higher water regime, being 44.8% higher when compared to the lower water regime. The soil moisture was positively correlated with the soil attributes with the exception of the number of AMF spores. The community of AMF associated with wheat genotypes was similar, comprising of 12 species, predominantly Claroideoglomus etunicatum and Glomus macrocarpum. The low variation among wheat genotypes for AMF diversity suggests no selective influence of the plants on the AMF community in the area of the study. Water regime was shown to be a dominant factor in mycorrhizal association. MenosMycorrhizal association contributes to plant growth, influencing tolerance to abiotic stresses such as water deficit.

A bioinformática e a genômica trabalham com bases de dados fora do padrão tradicional ou clássico que, por sua vez, caracterizam-se pela organizacão tabular e pelo tratamento destas em SGBDRs. Arquivos de genótipos são exemplos de bases de dados não clássicas e são caracterizados por serem gerados como arquivos textos, com dados desbalanceados, com alta dimensionalidade e por ocuparem muito espaço, entre outros aspectos. Os SGBDRs não têm se mostrado uma boa solucão para o tratamento de tais bases e, portanto, o presente trabalho busca avaliar o desempenho relativo entre bancos de dados NoSQL que representam duas famílias de diferentes modelo de dados, a partir de cenários de teste para a manipulação de arquivos de genótipo. |
