Outline of Final Research Achievements

Tomato yellow leaf curl virus (TYLCV) is a causal agent of tomato yellow disease and lead to devastating crop loss. Curing this disease is almost impossible but sometimes "recovery" can be seen at a high temperature. "Recovery" is a phenomenon that show no symptoms with new leaves from plants that show symptoms. Therefore, it may be possible to establish a novel method to cure virus-infected plants. In this experiments, about half number of tomato plants showed recovery at 30℃. But the recovered leaves showed accumulation of viral genomic DNA, suggesting that "recovery" is not the result of disappearance of the virus.
