Abstract:
The ultrastructures of hypocotyls of resistant and susceptible wild soybeans infected with zoospores of Phytophthora sojae from 3 to 72 h after inoculation were observed using transmission electron microscopy in this paper. The results showed that the cell structures of the susceptible wild soybean were seriously destroyed with the inoculation time from 3 to 36 h, but those of the resistant one were almost intact. The sediments on the cell wall of the resistant soybean could be seen at 48 h after inoculation, but no sediments could be seen for the susceptible one and its cell wall began to degrade to some extent. Although there was plasmolysis at 72 h after inoculation, the cell structures were almost intact for the resistant wild soybean. However, there were nearly no intact cell structures for the susceptible ones. The results could provide theoretical basis on cytology for clarification of pathogenic mechanism of P. sojae to wild soybeans.
