Résumé :

Predictions of future climatic conditions are uncertain and might be influenced by number of different factors. One of the forest management strategies to increase adaptation in such conditions is to diversify – increase number of genetic entries within species or species used. In Latvia relative large areas are occupied by poor, sandy soil, suitable only for Scots pine. Therefore aim of the s ...

Résumé :

The current benchmark for genetic value prediction is program-wide multivariate Best Linear Unbiased Prediction of measured traits, from which harvest age traits are predicted and then combined into economic indices. This is a very flexible framework, but is demanding to implement and not many programs have done so. Models for hybrid populations, calculation of standard errors for harvest trai ...

Résumé :

The amount of genetic diversity within forest tree breeding programs is much higher than in crop species. While the development of molecular tools for forest tree species has been lagging behind crop species, there are currently a large amount of resources developed for major species. The large amount of genetic diversity and other population characteristics has been cited as an advantage for ...

Résumé :

Many conifer breeding programs have entered into advanced generation and breeding against the negative genetic correlation (unfavourable relationship between wood quantity and quality) has become one of the biggest challenges in conifer breeding. Both selection strategy and population mating strategy were proposed for balancing wood properties and quantity in forest tree breeding program. For ...

Résumé :

Until the era of impregnated timber the heartwood of Scots pine (Pinus sylvestris L.) was traditional material in constructions prone to decay. Along with increasing concern about the ecological impacts of wood preservation chemicals, the natural durability of wooden structures has become important again. In Scots pine heartwood timber, the concentration of stilbenes and total phenolics has pr ...

Résumé :

Spruce bark beetle Ips typographus (L.), the most serious killer of mature Norway spruce Picea abies (L.) Karsten, is often associated with several phytopathogenic fungi including Ceratocystis polonica (Siem.) C. Moreau to overcome tree resistance. Conifers have constitutive and inducible resistance again invader. Induction of terpenoid-based oleoresin has long been considered important in con ...

Résumé :

Retrotransposon activity could be a major factor in genome instability, rearrangements and therefore also plasticity of the plant genome and adaptation to changing environmental conditions. This study examines retrotransposon-like sequences in the expression profile of stressed Scots pine (Pinus sylvestris L.) trees. Our initial results suggest the existence of several groups of active retrotr ...

Résumé :

One of the most important inducible defense mechanisms is the biosynthesis of pathogenesis – related (PR) proteins. Members of the PR – 5 groups are called thaumatin – like proteins (TLPs) because their amino acid sequences are homologous to thaumatin, a sweet – tasting protein from the West African shrub Taumatococcus danielli. Many PR – 5 proteins are induced in plants in response to infecti ...

Résumé :

Gene copy number variation (CNV) has been found to be common in the human genome, however, in plants, it has not been as widely studied. CNV analysis in Pinus sylvestris has been undertaken using real-time PCR in our laboratory. Genes analysed include the thaumatin-like protein (TLP) gene, defensin 2, and Pinus sylvestris pinosylvin synthase gene, as well as some genes involved in the lignin b ...

Résumé :

Scots pine (Pinus sylvestris L.) is a species of great economic importance in the Northern hemisphere. Wood volume and quality are the most important aspects of commercial forestry production, and studies of wood formation are becoming more important in order to increase the value and efficiency of forestry production. The phenylpropanoid pathway produces various compounds with diverse functio ...
