Shortening of telomeres has been connected with ageing and loss of cell replication or regeneration capacity. The aim of the present study was to examine potential variation in the length of telomeric repeats in silver birch (Betula pendula Roth) using clonal materials consisting of different-aged outdoor trees and tissue cultures of seven genotypes. The(More)
The shortening of telomeres, the specific structures at the end of the eukaryotic chromosomes, has been associated with ageing and loss of cell replication or regeneration capacity. The aim of this study was to determine the variation in telomeric repeats during the life-span of Scots pine (Pinus sylvestris L.) by studying different tissues and age groups(More)
A small multigene family encodes 4-coumarate:CoA ligases (4CLs) catalyzing the CoA ligation of hydroxycinnamic acids, a branch point step directing metabolites to a flavonoid or monolignol pathway. In the present study, we examined the effect of antisense Populus tremuloides 4CL (Pt4CL1) to the lignin and soluble phenolic compound composition of silver(More)
Tricholoma matsutake is an ectomycorrhizal fungus that forms commercially important mushrooms in coniferous forests. In this study, we explored the ability of T. matsutake to form mycorrhizae with Pinus sylvestris by inoculating emblings produced through somatic embryogenesis (SE) in an aseptic culture system. Two months after inoculation, clones with less(More)
Testing of candidates as clones would greatly benefit breeding of Scots pine (Pinus sylvestris L.), but has not been applied because of vegetative propgation of the species is difficult. With a common interest in Scots pine breeding, forest research institutions from Sweden, Finland, and Latvia (Skogforsk, Metla, and Silava, respectively) joined in a(More)
Variation of telomeric repeats in Scots pine (Pinus sylvestris) – is there a connection to ageing and loss of regeneration ability? The shortening of telomeres, the specific structures of repeated DNA sequence at the end of the eukaryotic chromosomes, has been connected with ageing and loss of cell replication or regeneration capacity. There is, however,(More)
