Outline of Final Research Achievements

Linalool had anti-bacterial activity against citrus canker (Xcc) and is highly accumulated in the leaves and mature fruits of Ponkan mandarin with the field resistance to Xcc. Satsuma mandarin had 3 linalool synthase genes in the genome and their transcription increased in response to wounding and the attacks of bacterial and fungi. Transgenic orange leaves harboring transgene of linalool synthase suppressed the growth of Xcc and accumulated high transcripts of pathogen related genes, indicating that linalool might be involved in the induction of non-host resistance in citrus.
