“…The increase in total monoterpenes (hydrocarbides) after treatment is in agreement with all previous results of phloem and sapwood reactions in different conifer species (Shrimpton, 1973;Russel and Berryman, 1976;Raffa and Berryman, 1982a, b;Schuck, 1982;Miller et al, 1986;Delorme and Lieutier, 1990 The conclusion that the reaction is nonspecific for the agression supports the results of Cook and Hain (1985), with Loblolly pine and 2 strains of Ophiostoma minus, and of Delorme and Lieutier (1990) with Scots pine and 3 different fungi and 1 beetle species. In his histological studies, Mullick (1977) …”

“…This is explained by the fact that reactive sapwood had a composition close to that of unwounded sapwood. Shrimpton (1973) only found an increase in β-phellandrene, which is contrary to our results, but this may be due to betweentree variation in the qualitative response, as observed by Schuck (1982) in the sapwood of P abies and by Delorme and Lieutier (1990) (1988) suggested that the neosynthesis against a beetle-associated fungus in Pinus pinaster is preceded by the reactivation of previously inactive cells.…”

“…Raffa and Berryman (1982b) found that the percentages of α-pinene and limonene increase while Δ3-carene decreases in the response of P contorta to O clavigerum while in our experiment concentrations of α-pinene and Δ3-carene both increased. These results suggest that between-tree variability in monoterpene composition is the rule in the response of P contorta, as is also true for P abies (Schuck, 1982) and P sylvestris (Delorme and Lieutier, 1990).…”

Summary — The monoterpene response of phloem and sapwood of individual pines belonging to 3 species (Pinus contorta, Pinus ponderosa and Pinus monticola) to inoculation with Ophiostoma clavigerum and injection with chitosan, a proteinase inhibitor-inducing factor and a control buffer, was investigated quantitatively and qualitatively. The total quantity of monoterpene in the reactive tissues increased with each treatment but to different levels. In each tree, the monoterpene composition of the reactive tissues differed from that of the unwounded tissues, but was the same whatever the treatment, even in the case of an injection with buffer control. In addition, phloem and sapwood responses were qualitatively identical although constitutive compositions differed greatly. The composition of reactive tissues was not very different from that of unwounded sapwood. The direction of variation of each monoterpene from unwounded to reactive tissues differed according to the particular tree. Only phellandrene + limonene reacted consistently. From these results we cannot conclude that chitosan is a natural elicitor, and the non-specificity of the response for the aggression favors the hypothesis that an elicitor originates from the tree itself. Because of this non-specificity, and the fact that the three trees responded in a qualitatively different manner, we suggest that the qualitative monoterpene response of the tree is not adapted to any specific aggressor even though these trees are usually hosts of the same bark beetle-fungus complex. Thus, the role of monoterpenes in the induced defensive response is very likely a quantitative and dose-dependent relationship.

Antimicrobial defences in the wood of living trees

summary The wood (xylem) in a living tree is protected from microbial attack by the secondary plant surface (periderm and rhytidome), which provides an effective barrier preventing the entry of most potential pathogens, and by constitutive and induced defence mechanisms in the bark (cortex and phloem). Although a few pathogens are able To penetrate these outer tissues directly, most xylem pathogens gain entry through wounds that expose this tissue and render it more vulnerable to attack. In functional sapwood, microbial colonization might be restricted by active defence mechanisms, or by passive microenvironmental restriction consequent upon the high water content and low availability of O2 in healthy conductive xylem. These factors are not mutually exclusive: indeed, they may operate in concert in many host‐pathogen interactions. Sapwood lesions made by wood‐decaying fungi are characteristically bounded by multiccllular walls OT barrier zones (compartmentalization wall 4 barriers and reaction zones (column boundary layers)), which may function both as inhibitory or degradation‐resistant barriers to further pathogen spread, and as seals to maintain xylem function and prevent the drying and aeration that could predispose to further infection. A range of putative antimicrobial defence mechanisms contributing to the effectiveness of such barriers has been identified in sapwood tissues. This includes cell wall alterations, constitutive and induced antimicrobial compounds, necrotic responses of living cells and the deposition of gummy materials, often resinous or polyphenolic, at the host‐pathogen interface. Nutritional, environmental and anatomical features of living wood might also contribute to pathogen restriction. Although there might be differences in detail, the defences operating in gymnospenns and angiosperms are generally similar. Defence responses against a variety of pathogen categories also have much in common. Dynamic studies are crucial in elucidating the roles of the various components of the host‐pathogen interaction in the wood of living trees. A model for the protection and defence of xylem tissues in woody angiosperms is suggested, based largely upon results from dynamic studies of host‐pathogen interactions in the wood of sycamore (Acer pseudoplatanus L.).

The chemical composition of the monoterpene fraction in wounded wood of Picea abies and its significance for the resistance against wound infecting fungi

Abstract: The wood of Picea abies reacts to injuries with an alteration of the terpene fraction in the resin. This fact may play a role in the host-parasite interaction. The significance for resistance against wound infecting fungi is discussed.
