Poplar plants were exposed to 20uM air-borne methyl jasmonate (MJ)every 72 h for 4 weeks. In the short-term (72 h), MJ-treated plants either induced or increased part-specific expression of two genes, wound-inducible 4 and bark storage protein. Also, rapid part-specific changes in the abscisic acid (ABA) concentration occurred in the MJ-treated plants. In the long-term the MJ treatment resulted in part-specific alterations in protein and nitrogen concentration and, BSP and WIN4 accumulation. These results suggest that MJ is involved in the regulation of nitrogen metabolism.
