COMMENTARY

LITERATURE

evolution

Cananga odorata var. fruticosa

-

the enzyme belongs to the terpene sythase superfamily, subfamily TPS-b. The arginine-tryptophan motif, R(R)X8W, present at the N-terminus of most mono-TPS and in some sesqui-TPS and di-TPS, is found in CoTPS3

malfunction

Zea mays

Q2NM15

transgenic maize plants overexpressing EREB58 show constitutive overaccumulation of TPS10 transcripts and also two major TPS10 products, (E)-beta-farnesene and (E)-alpha-bergamotene. By contrast, the contents of these two sesquiterpenes are reduced in EREB58-RNAi transgenic lines, in which the expression of TPS10 is suppressed

Q2NM15

the region from -300 to -200 of the maize TPS10 promoter is both necessary and sufficient for its inducibility by herbivory, the herbivore- and jasmonate-responsive AP2/ERF transcription factor EREB58 is a positive regulator of TPS10 expression and TPS10 volatile emission in maize, and plays a potential role in indirect defense against herbivores in maize, EREB58 binds directly to the GCC-box within the promoter fragment from -300 to -200 and promotes TPS10 expression, phylogenetic analysis, overview

metabolism

Zea mays

Q2NM15

the herbivore-induced sesquiterpenes of maize are mainly produced by two terpene synthases, TPS10 and TPS23, which convert the substrate farnesyl diphosphate (FPP) into various structurally diverse products

physiological function

Zea mays

Q2NM15

enzyme TPS10 forms (E)-alpha-bergamotene and (E)-beta-farnesene along with 13 minor sesquiterpenes in herbivore-damaged leaves

physiological function

Cananga odorata var. fruticosa

-

recombinant CoTPS3 catalysed the conversion of farnesyl pyrophosphate to alpha-bergamotene, from farnesyl diphosphate. The enzyme is part of the biosynthesis of volatile organic compounds (VOCs) in flowers. Floral scents are a key factor in plant-insect interactions and are vital for successful pollination. The scented flowers of Cananga odorata var. fruticosa are analysed by GC-MS and a total of 49 VOCs are identified at four different stages of flower development. The bulk of these VOCs are terpenes, mainly sesquiterpenes
