| 内容記述 | Cuscuta species is one of the most widespread group of parasitic plants that subsist on various plant species. Since their host plants include economically important crops, understanding the molecular basis of parasitism of Cuscuta species is of critical importance to crop production. We previously investigated the dose-response relationship of the rates of seed germination, seedling growth and parasitism to determine the ion-beam irradiation dose suitable for producing a large scale of population harboring mutants. The parasitism was clearly inhibited when the seeds were irradiated at a dose higher than 100 Gy. Unexpectedly, however, there was little inhibition of seed germination by irradiation, although seedling growth was affected by higher doses of irradiation. To elucidate the different response of parasitism, seed germination and seedling growth by high doses of irradiation, we investigated the effects of irradiation using the in vitro experimental system, the haustorium development by tactile stimuli and blue light irradiation. The results showed that high doses of irradiation had an especially severe impact on the formation of the haustorial primordia with a high level of DNA replication. High doses of irradiation seemed to have no or less effect on seed germination and seedling growth. Since ion-beam irradiation causes an inhibition of accurate DNA replication, the findings suggest that the seed germination and seedling growth of C. campestris may be less involved in DNA replication. | |||||
