Our goal is to acquire critical molecular data on the Asian soybean rust (ASR) infection process in susceptible and resistant soybean cultivars. To define specific molecular events in the soybean plant that are associated with ASR resistance and susceptibility, we detected gene expression over a 7-day time course in both ASR- and mock-infectecd leaves from susceptible and resistant (Rpp2) cultivars by using Affymetrix Soybean GeneChip microarrays. Statistical analysis showed that l ,516 and 894 genes in the susceptible and resistant cultivars, respectively, significantly changed expression. Most genes were differentially expressed within the first 3 days after infection (dai), followed by a 2-day time period in which very few genes were differentially exprcssed. After 4 dai, host gene expression diverged again between mock- and ASR-infected leaves. Arabidopsis homologs were identified for 1,302 and 773 differentially regulated genes in the susceptible and resistant cultivars, respectively, which allowed us to perform functional classification. These analyses revealed that genes with functions in metabolism and disease/defense were statistically overrepresented in both the susceptible and resistant cultivars gene lists. ASR-regulated genes involved in signal transduction and energy generation were overrepresented in the susceptible cultivar, while genes with functions in transport and transcription were overrepresented in the resistant cultivar. ASR-regulated genes involved in post-transcriptional regulation or with no known function were underrepresented in both cultivar?, and genes involved in cell structure, growth and development, and protein synthesis appeared to be underrepresented in the resistant cultivar.

Título em inglês: Soybean seeds inoculation with Bradyrhizobium at pre-sowing. |
|
Conteúdo: |
O objetivo deste trabalho foi avaliar o efeito da inoculação de Bradyrhizobium em pré-semeadura de soja e o efeito do tratamento das sementes com fungicidas na nodulação. Foram usados controles sem inoculação, que receberam ou não a aplicação de 200 kg ha-1 de N. A inoculação em pré-semeadura mostrou desempenho igual à inoculação padrão quanto à nodulação, produção de matéria seca, produtividade de grãos e acúmulo de nitrogênio nos tecidos e grãos da soja. Entretanto, quando as sementes foram tratadas com fungicidas, houve redução da nodulação e da produtividade. |
