“…and pine (Pinus spp.). Sitka spruce (Picea sitchensis), a conifer species in which most genotypes are highly susceptible to weevils (1), is native to the temperate rainforest ecosystem of the North American Pacific coast, and is also an economically valuable forest tree in Europe. Susceptibility to weevils caused the nearly complete halt of commercial Sitka spruce reforestation in the Pacific Northwest.…”

Background: (ϩ)-3-Carene/(Ϫ)-sabinene synthases are associated with insect resistance in Sitka spruce. Results: Amino acid position 596 is critical for the monoterpene synthase product profile. Conclusion: This work revealed mechanistic underpinnings for patterns of functional evolution of this monoterpene synthase family. Significance: Catalytic plasticity of conifer monoterpene synthases is a major factor in the diversification of the TPS-d family and evolution of insect resistance.

“…Susceptibility to weevils caused the nearly complete halt of commercial Sitka spruce reforestation in the Pacific Northwest. However, successful field trials identified a few highly resistant Sitka spruce genotypes; most notably genotype H898, which has become a focus for research and breeding of conifer resistance to stem boring insects (1).…”

“…Selection for resistance in these trials was conducted by measuring damage rates resulting from infestations that developed naturally. Results based on natural infestations of trial sites re-confirmed the area of Haney, BC as a source of resistant genotypes, and identified two new geographic sources of Sitka spruce resistance: the Big Qualicum River area on eastern Vancouver Island and the Skeena River area of BC's mainland, which falls in the introgression zone where Sitka and white spruce hybridize (Alfaro and Ying 1990, Ying 1991, King 1994, Ying and Ebata 1994, Ying 1997, King et al 2004 (Fig. 3).…”

The Sitka spruce (Picea sitchensis [Bong.] Carr) breeding program for resistance against the white pine weevil Pissodes strobi Peck (Coleoptera: Curculionidae) is arguably one of the most successful pest resistance breeding programs for plantation forest species in North America, with a substantial proportion of the planting stock in BC and Washington State currently coming from this breeding program. Using conventional selection and breeding, and by screening Sitka spruce populations using artificial weevil infestations, we identified sources of heritable and stable weevil resistance. We also used this program to investigate potential causes behind this resistance and identified several heritable resistance mechanisms, including anatomical characteristics, such as constitutive resin canals and sclereid cells in the bark, terpene defenses and variation in tree phenology. We concluded that resistance is conferred by a suite of traits whose composition varies among resistant sources. In addition, we evaluated the efficiency of screening for resistance using weevil population enhancement as a screening method. Our results culminated in the establishment of seed orchards, and the availability of resistant seed that is contributing to the return of Sitka spruce as a species of choice in coastal British Columbia. Keywords: Picea sitchensis, Pissodes strobi, forest pest management, genetic resistanceDedication: This paper is dedicated to Dr. John Borden of Simon Fraser University (retired) who championed this topic and whose vision inspired so many entomologists in North America -René Alfaro. RÉSUMÉLe programme de sélection de l' épinette de Sitka (Picea sitchensis [Bong.] Carr) visant à accroître la résistance au charançon du pin blanc Pissodes strobi Peck (Coleoptera: Curculionidae) est sans aucun doute l'un des programmes de sélection pour la résistance aux ravageur qui a connu le plus de succès chez les espèces forestières utilisées en plantation en Amé-rique du Nord et il produit une partie importante des stocks plantés actuellement en C.-B. et dans l'État de Washington. En utilisant des méthodes de sélection et de culture classiques, et en soumettant les populations d' épinette de Sitka à des infestations artificielles de charançon, nous avons identifié des sources de résistance au charançon qui sont transmissibles et stables. Nous avons également utilisé ce programme pour étudier les causes potentielles de cette résistance et avons identifié quelques mécanismes de résistance transmissibles, notamment des caractéristiques anatomiques, comme les canaux résinifères transversaux et les cellules sclérites de l' écorce, les terpènes de défense et les variations dans la phéno-logie de l'arbre. Nous en concluons que la résistance vient d'un ensemble de traits dont la composition varie entre les sources résistantes. De plus, nous avons évalué l' efficacité du dépistage pour la résistance en intensifiant des populations de charançon pour effectuer criblage. Nos résultats ont mené à la création de vergers à graines...

Conifer defense against insects: Proteome analysis of Sitka spruce (Picea sitchensis) bark induced by mechanical wounding or feeding by white pine weevils (Pissodes strobi)

Feeding insects can have major ecological and economic impacts on both natural and planted forests. Understanding the molecular and biochemical mechanisms by which conifers defend themselves from insect pests is a major goal of ongoing research in forest health genomics. In previous work, we demonstrated a complex system of anatomical, chemical, and transcriptome responses in Sitka spruce (Picea sitchensis) upon feeding by the economically significant insect pest, the white pine weevil (Pissodes strobi). In this study, changes to the proteome of Sitka spruce bark tissue were examined subsequent to feeding by white pine weevils or mechanical wounding. 2-D PAGE and high-throughput MS/MS were used to examine induced changes in protein abundance and protein modification. Significant changes were observed as early as 2 h following the onset of insect feeding. Among the insect-induced proteins are a series of related small heat shock proteins, other stress response proteins, proteins involved in secondary metabolism, oxidoreductases, and a novel spruce protein. Comparison of protein expression and cDNA microarray profiles of induced spruce stem tissues reveals the complementary nature of transcriptome and proteome analyses and the need to apply a multifaceted approach to the large-scale analysis of plant defense systems.
