| Research Abstract |
In this study, the transcription profiles of host genes induced by rhizobial, arbuscular mycorrhizal and dual inoculations were analyzed to elucidate the host genes involving in the establishment of the dual symbiosis in soybean root. We found that 34 genes of host plant were induced commonly by rhizobial, mycorrhizal and dual inoculations, suggesting that these genes are essential for establishing dual symbiosis. The gene expression of type1 metallothionein and CPRD49 were examined using real-time RT-PCR. It was ascertained that the expression of type1 metallothionein gene was significantly induced in the root nodule and mycorrhizal root of soybean. We tried to examine the spatial expression patterns of type1 metallothionein gene in the transgenic hairy roots using promoter-gus gene fusions.
