Calcium ion (Ca2+)
is a signal molecule that plays crucial roles in plant secondary metabolism. In
order to explore the signaling mechanism of endophytic fungal elicitors (Penicilliumcommune 2J1) for promoting essential oil accumulation in Cinnamomumlongepaniculatum, changes in the contents of Ca2+ and
essential oil were investigated after the addition of elicitors to the C.longepaniculatum cultures. The essential oil contents in C.longepaniculatum cells were increased
upon addition of the CaCl3 into the culture. The concentration of Ca2+ was suppressed and the essential oil contents decreased after the Ca2+ channel blocker (LaCl3) was added into the cell cultures. LaCl3 did not completely inhibit essential oil accumulation in C.longepaniculatum cells
induced by endophytic fungal elicitors. Based on these experimental results, adding
elicitors were found to significantly increase Ca2+ concentration
and essential oil synthesis in C.longepaniculatum cells. Reliable
evidence that Ca2+ can effectively mediate endophytic fungal
elicitors to promote essential oil synthesis in C.longepaniculatum cells
is presented in this study. It is further demonstrated that endophytic fungal
elicitors may facilitate essential oil synthesis
in C.longepaniculatum suspension cells through other signal
transduction pathways.
