Abstract:
The strain was identified as Boeremia exigua var.exigua, which was collected form Jingyu County of Baishan City in Jilin, based on the morphological characteristics of the colony and conidia，rDNA-ITS,partial actin gene,beta-tubulin gene,RNA polymerase II second largest subunit gene,translation elongation factor 1 alpha gene,large subunit ribosomal RNA gene, the pathogenicity to young soybean, phylogenetic tree construction and analysis of the above 6 primers. It was the first report that Boeremia exigua var.exigua infected soybean in China.In the phylogenetic tree analysis results, rpb2 and TEF gene show a good discrimination in interspecies relationship, they are more suitable for identifying and studying intergenetic relationships of Boeremia.
