Molecular dissection of the quantitative inheritance of wood property traits in loblolly pine

Abstract: -Significant progress has been made toward the molecular dissection of the quantitative inheritance of wood property traits in loblolly pine (Pinus taeda L.) and several other forest tree species. QTL mapping experiments have been used to reveal the approximate number of genes controlling traits such as wood specific gravity and microfibril angle and the individual effects of these genes on the total phenotypic variance for the trait. These analyses help to define the scope of the challenge to identify genes c… Show more

“…Different wood quality components can thus be analysed: wood density and ring width of each ring or ring part. Applying this method, accurate QTL detection for wood components becomes possible without tree destruction, as shown in several studies in Pinus taeda [11,16].…”

“…In an integrative study, it will be essential to use the same markers (ESTs) for comparative mapping and the candidate gene approach, in order to validate the candidate gene-QTL co-locations between phylogenetically related species [39].…”

“…Second, we quickly established a fully saturated map based on AFLP markers. Third, we are now mapping QTL for traits of interest and developing SSRs and ESTPs (EST Polymorphisms) to provide more informative markers which should be easily transferred to other pedigrees of maritime pine and other pine species, with the main objective of QTL validation [39]. The main goal of this paper is to present a saturated map of maritime pine which corresponds to the second step of this strategy.…”

“…In the QTL analyses some false positives were found, probably in part because total progeny sample sizes were limited and progeny were located across a number of field trials. Generally, individual QTL explained or accounted for only a small proportion of the total phenotypic variation, similar to that found in loblolly pine [13]. For instance the different wood density QTL explained from 5.4% to 6.5% of the variation.…”
