ABSTRACT=<p>Terpene synthase (<italic>TPS</italic>) is related to the production of aromatic substances, but there are few studies on the impact of abiotic stress on <italic>TPS</italic> and its molecular mechanism, especially in peaches. This study found that salt resistance and abscisic acid (ABA) sensitivity of transgenic tomatoes were enhanced by overexpression of <italic>PpTPS1</italic>. Moreover, it was found that <italic>PpTPS1</italic> interacted with and antagonized the expression of the <italic>bZIP</italic> transcription factor <italic>ABA INSENSITIVE 5</italic> (<italic>PpABI5</italic>), which is thought to play an important role in salt suitability. In addition, <italic>PpTCP1</italic>, <italic>PpTCP13</italic>, and <italic>PpTCP15</italic> were found to activate the expression of <italic>PpTPS1</italic> by yeast one-hybrid (Y1H) and dual-luciferase assays, and they could also be induced by ABA. In summary, <italic>PpTPS1</italic> may be involved in the ABA signaling regulatory pathway and play an important role in salt acclimation, providing a new reference gene for the improvement of salt resistance in peaches.</p>
