Many terrestrial plants respond to flooding with enhanced ethylene production. The roots of flooded plants produce 1-aminocyclopropane-1-carboxylic acid (ACC), which is transported from the root to the shoot, where it is converted to ethylene. In the roots, ACC is synthesized by ACC synthase, which is encoded by a multigene family. Previously, we identified two ACC synthase genes of tomato that are involved in flooding-induced ethylene production. Here, we report the cloning ofLE-ACS7 , a new tomato ACC synthase with a role early during flooding but also in the early wound response of leaves. The promoter ofLE-ACS7 is tagged by aSol3 transposon. ASol3 transposon is also present in the tomato polygalacturonase promoter to which it conferred regulatory elements. Thus,Sol3 transposons may affect the regulation ofLE-ACS7 and may be involved in the communication between the root and the shoot of waterlogged tomato plants.
