4.2.3.104 up Diprion pini oviposition enhances the transcription of sesquiterpene synthase TPS1 by 17.5fold. The transcripts TPS1 and TPS2 are induced in combinations of pine and sawfly species only when the egg-laden needles are attractive to Closterocerus ruforum, which parasitizes sawfly eggs 716459 4.2.3.104 up expression is induced upon wounding or methyljasmonate treatment 730575 4.2.3.104 up in the presence of 1 mg/ml lithium acetoacetate, a 13.6fold increase in alpha-humulene production occurs compared with the control 690593 4.2.3.104 up methyl jasmonate slightly induces the expression of enzyme alpha-humulene synthase, at 6 h after methyl jasmonate treatment, the expression of the alpha-humulene synthase gene has increased approximately 1.5fold resulting in 330 pmol/mg protein/h alpha-humulene production 748440 4.2.3.104 up the enzyme is up-regulated in both leaves and rhizomes after treatment with methyl jasmonate 718244 4.2.3.104 up the transcript of ZZS1 gene increases very rapidly from June 12 to June 28, a period of strong temperature increase in 2007. Transcript level remains high throughout the summer and autumn, but declines significantly in December 717468
