From: The terpene synthase (TPS) gene family in kiwifruit shows high functional redundancy and a subset of TPS likely fulfil overlapping functions in fruit flavour, floral bouquet and defence

Terpenes produced and AcTPS gene expression changes after herbivory by brown-headed leaf rollers (BHLR). A Terpene accumulation in tissue culture leaves of kiwifruit ‘Hort16A’ and ‘Hayward’ either infested with BHLR or untreated control leaves. Leaf tissues were harvested after 6 d, ground to powder, and terpenes analysed by SPME GC–MS. B Terpene emission from tissue-cultured leaves of kiwifruit either infested with BHLR or untreated control. An insect-only sample (without plants, only insects, nutrients and agar) was also collected. Terpenes were collected by Tenax TA during 6 d feeding and analysed by GC–MS. C Transcript abundance of terpene synthase genes in infested and control leaves. Gene expression was determined by qRT-PCR. Data are means ± SE (n = 3). The Student’s t-test was used to test for statistical significance. Asterisks indicate a significant difference between caterpillar infested and untreated control leaves (*P < 0.05, **P < 0.01)
