Cloned (Comment)	Organism
gene TPS10, identification of the region from -300 to -200 of the maize TPS10 promoter as both necessary and sufficient for its inducibility by herbivory through 5' deletion mapping in Arabidopsis thaliana. Gene EREB58 has a spatiotemporal expression pattern highly similar to that of TPS10	Zea mays

Expression

Organism	Comment	Expression
Zea mays	jasmonate induction of gene TPS10. The region from -300 to -200 of the maize TPS10 promoter is both necessary and sufficient for its inducibility by herbivory, phylogenetic analysis identifies the herbivore- and jasmonate-responsive AP2/ERF transcription factor EREB58 as a candidate regulator of TPS10 in maize, EREB58 binds directly to the GCC-box within the promoter fragment from -300 to -200 and promotes TPS10 expression	up

General Information

General Information	Comment	Organism
malfunction	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	Zea mays
metabolism	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	Zea mays
additional information	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	Zea mays
physiological function	enzyme TPS10 forms (E)-alpha-bergamotene and (E)-beta-farnesene along with 13 minor sesquiterpenes in herbivore-damaged leaves	Zea mays
