infection of in vivo and in vitro pines with the pinewood nematode bursaphelenchus xylophilus and isolation of induced volatiles

The pinewood nematode (PWN), Bursaphelenchus xylophilus (Steiner &#38; B&#252;hrer 1934)&#160;Nickle 1970, is a plant parasitic nematode that mainly parasitizes Pinus species. This phytoparasite is vectored by insects of the genus Monochamus into trees of susceptible pine species during the insect&#39;s maturation feeding. The PWN kills the tree by attacking its resin canals and reducing resin flow, and by damaging its vascular tissue, causing interruptions in the water column. Lack of water at the tree canopy induces the first visible symptoms of pine wilt disease (PWD), i.e., the pine needles become chlorotic after the cessation of photosynthesis and drooping due to desiccation. Pine generally responds to biotic and abiotic stress through the production of resin and volatile compounds1. Thus, understanding the mechanisms of pine defense is important to determine the specific effects of PWN attacks and to find alternative methods for pest control2.
Currently, experimentation under field conditions is dependent on the availability of infected pines, the confirmation of PWN infection, and variable environmental conditions. Under greenhouse conditions, these parameters can be more easily controlled; however, the genetic diversity of the host becomes a strong source of variability3. For example, in a study on the resistance response of Pinus pinaster, the production of the terpene limonene and resin acids was associated with PWN infection4. However, due to the small number of samples and the variability of natural conditions, detectable changes were only registered for half the samples. In another study using greenhouse-grown pine seedlings, even though environmental conditions were more easily controlled, natural pine genetic diversity induced a great variability in the volatiles extracted5. Since disease-induced pine volatiles can be greatly influenced by environmental and genetic variation, resorting to in vitro shoot cultures is a good alternative for studies on the chemical and biochemical response of pine tissue to PWN infection5,6. By propagating a plant genotype in vitro, its genetic makeup can be maintained and cloned indefinitely, leading to the establishment of a higher amount of genetically identical individuals in less space and under less time than in in vivo conditions. These cultures are a simple working system under easily manipulated nutritional and environmental conditions, so they offer additional advantages to conventional systems in the evaluation of the production and emission of volatiles7,8. These systems are particularly advantageous for research in woody species, which most of the time require substantial resources, i.e., target trees are sometimes located in hard-to-reach sites, require expensive equipment, a dedicated workforce, and longer time periods of analysis8. In vitro, co-cultures of pines with the PWN enable the assessment of metabolic interactions between the nematode and the plant at different stages9. For the analysis of volatiles, this is very important since profiling techniques have become highly accurate, and minute variations in sampling can result in substantial changes in volatile profiles. Gas chromatography coupled with mass spectrometry (GC-MS) is a powerful technique for the analysis of volatiles and allows a quick and streamlined profiling of volatiles10. The protocol presented here describes techniques for infecting in vivo pine seedlings under greenhouse conditions and in vitro shoot cultures of genetically identical pines optimized for the extraction and profiling of induced volatiles.

Pinewood Nematode Bursaphelenchus xylophilus 에 의한 In Vivo 및 In Vitro Pines 감염 및 유도 휘발성 물질의 분리

We have established an In Vitro co-culture system of Pine shoots with the Pinewood nematodes to market and study changes in host volatile response to these phytoparasites. Greenhouse biohouses allow control of environmental variability. However, the genetic diversity of Pine seedlings still influences the resulting volatile profiles.In Vitro Pine shoots infected with the Pinewood nematodes allow sampling of easily obtainable plant clones, which reduces the influence of variability coming from Pine genetic diversity. Plant volatiles are isolated by hydrodistillation in distillation extraction, but headspace techniques allow the profiling of volatiles emitted by the plant. Resin-packed columns will be used as a non-invasive technique to profile volatiles emitted by In Vitro ground Pine infected with Pine nematode for direct analysis of the chemical interplay between the host and the phytoparasite.
