Movie 1
Real-time imaging of Ca2+ signals induced in Arabidopsis upon sensing odorants.
Ca2+ signals were induced in Arabidopsis by odorants released from insect-damaged plants.

Movie 2
Ca2+ signals in Arabidopsis upon sensing (Z)-3-hexenal.
Ca2+ signals were induced in the leaves that sensed (Z)-3-hexenal volatilized from (Z)-3-hexenal solution.

Movie 3
Cell-level analyses of Ca2+ signals induced by (Z)-3-hexenal.
Upon exposure to (Z)-3-hexenal, Ca2+ signals were firstly observed in guard cells (left movie), secondly in mesophyll cells (central movie), and finally in epidermal cells (right movie).

Movie 4
(Z)-3-hexenal-induced Ca2+ signals in leaves treated with abscisic acid.
In the mutants that are deficient in stomatal closures (slac1 and ost1), (Z)-3-hexenal-induced Ca2+ signals were not delayed even when abscisic acid was treated.
