| Zusammenfassung: | © 2020 The Authors New Phytologist © 2020 New Phytologist Trust. Analysis of the updated reference tomato genome found 34 full-length TPS genes and 18 TPS pseudogenes. Biochemical analysis has now identified the catalytic activities of all enzymes encoded by the 34 TPS genes: one isoprene synthase, 10 exclusively or predominantly monoterpene synthases, 17 sesquiterpene synthases and six diterpene synthases. Among the monoterpene and sesquiterpene and diterpene synthases, some use trans-prenyl diphosphates, some use cis-prenyl diphosphates and some use both. The isoprene synthase is cytosolic; six monoterpene synthases are plastidic, and four are cytosolic; the sesquiterpene synthases are almost all cytosolic, with the exception of one found in the mitochondria; and three diterpene synthases are found in the plastids, one in the cytosol and two in the mitochondria. New trans-prenyltransferases (TPTs) were characterised; together with previously characterised TPTs and cis-prenyltransferases (CPTs), tomato plants can make all cis and trans C10 , C15 and C20 prenyl diphosphates. Every type of plant tissue examined expresses some TPS genes and some TPTs and CPTs. Phylogenetic comparison of the TPS genes from tomato and Arabidopsis shows expansions in each clade of the TPS gene family in each lineage (and inferred losses), accompanied by changes in subcellular localisations and substrate specificities |
