“…The number and effects of detected QTLs that were observed concurs with previously reported QTL studies for growth and wood quality traits in several species, particularly those dealing with smaller sample sizes (Bradshaw and Stettler 1995;Grattapaglia et al 1996;Wu 1998;Yoshimaru et al 1998;Sewell et al 2000Sewell et al , 2002Arcade et al 2002;Markussen et al 2003). We note that many of these studies report clustering of QTLs for related and unrelated traits.…”

Typical linkage and quantitative trait locus (QTL) analyses in forest trees have been conducted in single pedigrees with sex-averaged linkage maps. The results of a QTL analysis for wood quality and growth traits of coastal Douglas-fir using eight full-sib families, each consisting of 40 progeny, replicated on four sites are presented. The resulting map of segregating genetic markers consisted of 120 amplified fragment length polymorphism (AFLP) loci distributed across 19 linkage groups. The wood quality traits represent the widest suite of traits yet examined for QTL analysis in a tree species in a single study. Wood fiber traits showed the lowest number of QTLs (3) with relatively small effect (ca. 4%); wood density traits also showed just three QTLs but with slightly larger effect; wood chemistry traits showed more QTLs (7), while ring density traits showed many QTLs with large numbers of QTLs (78) and interesting patterns of temporal variation. Growth traits gave just five QTLs but of major effect (10-16%). Trees, with their long generation times, provide a rich resource for studies of temporal variation of QTL expression.

A three-generation outbred pedigree of 186 individuals was used to identify the genomic regions involved in the variability of chemical and physical wood properties of Pinus pinaster. A total of 54 quantitative trait loci (QTLs) was detected, with an average of 2.4 QTLs per trait. Clusters of wood properties QTLs were found at several points in the genome, suggesting the existence of pleiotropic effects of a limited number of genes. The colocalizations observed in this study are in accordance with the genetic correlations previously reported in the literature. In addition, in an attempt to identify the genes underlying the QTLs, nine wood quality candidate genes involved in cell wall structure were localized on the genetic map. Only one of them, Korrigan, a gene encoding for a β 1-4 endo-glucanase known in Arabidopis thaliana to be involved in polysaccharide biosynthesis, co-localized with a wood quality QTL cluster involved in hemicellulose content and fibre characteristics. This finding is in accordance with results previously reported for this gene regarding its expression variability (transcriptome and proteome levels) and patterns of molecular evolution. The pertinence of this result will be tested in more rigorous designs in order to identify early selection predictors for wood quality.

“…Wood property quantitative trait loci (QTLs) have been identified in many forest tree species, attesting the existence of major gene effects controlling part of the variation of wood and its end‐use properties (Bradshaw & Stettler, 1995; Grattapaglia et al ., 1996; Kumar et al ., 2000; Lerceteau et al ., 2000; Arcade et al ., 2002; Moran et al ., 2002; Neale et al ., 2002; Brown et al ., 2003; Markussen et al ., 2003). Co‐localizations of QTLs and candidate genes (Moran et al ., 2002; Brown et al ., 2003; Chagné et al ., 2003) have also been reported.…”

Nucleotide variation in genes involved in wood formation in two pine species

et al. 2005

Summary• Nucleotide diversity in eight genes related to wood formation was investigated in two pine species, Pinus pinaster and P. radiata .• The nucleotide diversity patterns observed and their properties were compared between the two species according to the specific characteristics of the samples analysed.• A lower diversity was observed in P. radiata compared with P. pinaster . In particular, for two genes ( Pp1 , a glycin-rich protein homolog and CesA3 , a cellulose synthase) the magnitude of the reduction of diversity potentially indicates the action of nonneutral factors. For both, particular patterns of nucleotide diversity were observed in P. pinaster (high genetic differentiation for Pp1 and close to zero differentiation associated with positive Tajima's D -value for CesA3). In addition, KORRIGAN , a gene involved in cellulose-hemicellulose assembly, demonstrated a negative Tajima's D -value in P. radiata accompanied by a high genetic differentiation in P. pinaster .• The consistency of the results obtained at the nucleotide level, together with the physiological roles of the genes analysed, indicate their potential susceptibility to artificial and/or natural selection.
