title: GTR1 is a jasmonic acid and jasmonoyl-l-isoleucine transporter in Arabidopsis thaliana.
abstract: Jasmonates are major plant hormones involved in wounding responses. Systemic wounding responses are induced by an electrical signal derived from damaged leaves. After the signaling, jasmonic acid (JA) and jasmonoyl-l-isoleucine (JA-Ile) are translocated from wounded to undamaged leaves, but the molecular mechanism of the transport remains unclear. Here, we found that a JA-Ile transporter, GTR1, contributed to these translocations in Arabidopsis thaliana. GTR1 was expressed in and surrounding the leaf veins both of wounded and undamaged leaves. Less accumulations and translocation of JA and JA-Ile were observed in undamaged leaves of gtr1 at 30 min after wounding. Expressions of some genes related to wound responses were induced systemically in undamaged leaves of gtr1. These results suggested that GTR1 would be involved in the translocation of JA and JA-Ile in plant and may be contributed to correct positioning of JA and JA-Ile to attenuate an excessive wound response in undamaged leaves.
