The enzyme catalyses a step in the formation of (3E)-4,8-dimethylnona-1,3,7-triene, a key signal molecule in induced plant defense mediated by the attraction of enemies of herbivores [1]. Nerolidol is a naturally occurring sesquiterpene found in the essential oils of many types of plants.
divalent metal ion cofactor is required for enzyme activity, KM-value for Mg2+: 0.47 mM. Mg2+ and Mn2+ give substantial activity, with Mg2+ at 5 mM giving the highest activity

transcripts are detected in the leaf and sheath tissue of 2-week-old uninjured maize plants, but none is found in the roots. After 16 h of herbivory by Egyptian cotton leafworm larvae, transcript levels in the leaves of maize cv B73 are induced about 8-fold. The tps1 transcript levels in the maize cv Delprim are high even in uninjured plants and are only marginally elevated by herbivory. In older plants (3 months), moderate levels of transcript are present in leaves of both herbivore-treated and untreated plants of both cultivars. 16 hours after the initiation of herbivore damage, there is a significant elevation in transcript level

The maize gene terpene synthase 1 encodes a sesquiterpene synthase catalyzing the formation of (E)-beta-farnesene, (E)-nerolidol, and (E,E)-farnesol after herbivore damage
