| Outline of Annual Research Achievements |
The role ethylene signaling during haustorial development was continually invested using cell division marker. Spacial-temporal cell division during haustorium development was further observed using histochemical approach, which further supports our previous observation where ethylene signaling-mediated cell division is associated with haustorium development.
Transcriptomics for analysis of gene expressions along haustorial development in wild type and ethylene mutant ein2 is under progress. To examine whether ethylene signaling is activated through elevation of ethylene level, the ACC level was tested in the roots and haustorium after in-vitro haustoiurm induction.
A new ethylene responsive marker has been generated for visualizing cellular activation of ethylene signaling during haustorium development.
Various ethylene inhibitors were tested during parasitic plant infection to host plants and the effective treatments of those inhibitors on host prevention against plant parasite infection were evaluated.
