Outline of Final Research Achievements

In order to uncover controling system of jasmonate signaling pathway, we attempted to find out UDP-glucose independent transglucosylation enzyme, and OsBGlu1 was picked up to afford 12-glucopyranosyl jasmonic acid and 12-glucopuranosyljasmonoyl L-isoleucine. The biological activities of jasmonic acid, 12-hydroxyjasmonoyl L-isoleucine and 12-glucopyranosyljasmonoyl L-isoleucine were comparied, which revealed that jasmonic acid has most effective activity and 12-hydroxyjasmonoyl L-isoleucine has the lowest activity. Thus, our project showed that transglucosylation reaction mediated by OsBGlu1 is important pathway to control the activity of jasmonic acid.
