“…The accumulation of CP was previously shown to be strongly induced by JA in N. attenuata and tomato (Solanum lycopersicum) plants (Keinänen et al, 2001;Chen et al, 2006), and CP accumulated in a dosedependent manner in JA-treated sweet pepper (Capsicum annuum) cotyledons (Tebayashi et al, 2007). The dependence of CP accumulation on JA was further highlighted using N. attenuata transgenic plants silenced in their expression of lipoxygenase 3 (antisense-LOX3), an enzyme essential for JA biosynthesis, which resulted in strongly reduced CP levels in M. sexta OS-elicited leaves (Paschold et al, 2007).…”

“…Previously, CP was tested as an ovipositioning deterrent in cotyledons of sweet pepper by dipping leaves in CP solutions (Tebayashi et al, 2007). Treated leaves showed fewer oviposition-associated punctures from Liriomyza trifolii compared with nontreated leaves, demonstrating for the first time a defensive function of CP against herbivores in plants.…”

R2R3-NaMYB8 Regulates the Accumulation of Phenylpropanoid-Polyamine Conjugates, Which Are Essential for Local and Systemic Defense against Insect Herbivores inNicotiana attenuata

Although phenylpropanoid-polyamine conjugates (PPCs) occur ubiquitously in plants, their biological roles remain largely unexplored. The two major PPCs of Nicotiana attenuata plants, caffeoylputrescine (CP) and dicaffeoylspermidine, increase dramatically in local and systemic tissues after herbivore attack and simulations thereof. We identified NaMYB8, a homolog of NtMYBJS1, which in BY-2 cells regulates PPC biosynthesis, and silenced its expression by RNA interference in N. attenuata (ir-MYB8), to understand the ecological role(s) of PPCs. The regulatory role of NaMYB8 in PPC biosynthesis was validated by a microarray analysis, which revealed that transcripts of several key biosynthetic genes in shikimate and polyamine metabolism accumulated in a NaMYB8-dependent manner. Wild-type N. attenuata plants typically contain high levels of PPCs in their reproductive tissues; however, NaMYB8-silenced plants that completely lacked CP and dicaffeoylspermidine showed no changes in reproductive parameters of the plants. In contrast, a defensive role for PPCs was clear; both specialist (Manduca sexta) and generalist (Spodoptera littoralis) caterpillars feeding on systemically preinduced young stem leaves performed significantly better on ir-MYB8 plants lacking PPCs compared with wild-type plants expressing high levels of PPCs. Moreover, the growth of M. sexta caterpillars was significantly reduced when neonates were fed ir-MYB8 leaves sprayed with synthetic CP, corroborating the role of PPCs as direct plant defense. The spatiotemporal accumulation and function of PPCs in N. attenuata are consistent with the predictions of the optimal defense theory: plants preferentially protect their most fitnessenhancing and vulnerable parts, young tissues and reproductive organs, to maximize their fitness.

Analisis senyawa volatil dari ekstrak tanaman yang berpotensi sebagai atraktan parasitoid telur wereng batang coklat, Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae)

ABSTRAKTanaman dapat menghasilkan senyawa volatil sebagai sarana komunikasi intra-atau inter-spesies. Tanaman yang terinfeksi herbivora akan memproduksi senyawa volatil sebagai mekanisme pertahanan tidak langsung yang dapat menarik musuh alami herbivora tersebut. Analisis senyawa-senyawa volatil yang diproduksi oleh tanaman padi akibat infestasi telur wereng batang coklat (WBC) dilakukan untuk mengidentifikasi komponen penyusun senyawa volatil yang berpotensi sebagai atraktan bagi parasitoid telur WBC, Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae). Kegiatan penelitian ini merupakan tahap awal dari pembuatan formula atraktan parasitoid WBC, meliputi ekstraksi senyawa volatil dari batang padi yang tidak terinfestasi dan terinfestasi telur WBC dengan menggunakan pelarut aseton dan n-heksana, analisis komponen senyawa volatil dengan menggunakan gas kromatografi spektroskopi massa (GC-MS), dan bioassay perilaku orientasi parasitoid terhadap senyawa volatil dengan metode olfaktometri. Metode ekstraksi yang digunakan adalah teknik maserasi dan ekstraksi kontinyu yang diikuti dengan pemekatan. Bioassay perilaku orientasi A. nilaparvatae dilakukan dengan menggunakan olfaktometer tabung Y dan untuk setiap lot bioassay digunakan 30 parasitoid telur yang diulang 3 kali. Hasil analisis menunjukkan bahwa senyawa volatil yang terdapat pada ekstrak tanaman padi yang terinfestasi telur WBC terdiri atas 16 komponen. Komponen dengan proporsi tertinggi pada metode dengan pelarut aseton adalah 2-Pentanon, 4-hidroksi-4-methil (19,9%), sedangkan dengan pelarut n-heksana adalah asam heksanadioat, dioktil ester (65%). A. nilaparvatae menunjukkan respon positif terhadap ekstrak tanaman padi yang terinfestasi telur WBC sehingga senyawa volatil yang terdapat pada ekstrak tanaman padi yang terinfestasi telur WBC dapat dimanfaatkan sebagai atraktan A. nilaparvatae untuk mendukung pengelolaan hama padi yang ramah lingkungan.Kata kunci: volatil, atraktan, Nilaparvata lugens, parasitoid ABSTRACTPlants produce volatiles as communication cues intra-or inter-species.

Tritrophic interaction among host plant-herbivore-parasitoid involves chemical cues. The infested plant by herbivores has been reacted to produce volatiles which is a cue used by the herbivore parasitoids for host location. These volatiles can be developed to enhance natural control of insect pests, especially by optimally use of parasitoids. Egg parasitoids are biocontrol agents that play an important role in natural control of herbivores. This research used a tritrophic interaction model of rice plant-brown plant hopper (BPH)-egg parasitoid of BPH. Research on analysis of chemical cues in tritrophic interactions was aimed to identify volatiles that are used by the parasitoid to find its host. The volatiles that effectively affect the parasitoid orientation behavior could be developed into a parasitoid attractant. Extraction of volatiles as the egg parasitoid cues was done using soxhlet, and identification of the volatiles using Gas Chromatography-Mass Spectrometry (GC-MS). Bioassay of the volatiles on the BPH parasitoid orientation behavior was performed using Y-tube olfactometry. The volatiles that are used for host location cues by the parasitoid affect the parasitoid orientation behavior by showing the preference of the parasitoid females to the odor of volatile. Volatiles extracted from BPH-egg-infested plants and uninfested plants contain alcohol, hydrocarbon, and ester compounds. Based on the difference of the compound composition of both extractions, five compounds of long-chain hydrocarbon, both branched and unsaturated compounds are the main volatile components which caused positive orientation behavior of the egg parasitoid. The egg parasitoids showed positive behavior orientation toward the volatiles extracted from BPH-egg-infested plant. Those hydrocarbon compounds are potential materials to be developed into bio attractants of BPH egg parasitoid.
