The bar gene conferring resistance to the herbicide Basta (containing phosphinothricin) was transferred to embryogenic cultures of Picea abies by particle bombardment and transformants were selected on Basta medium. In total, 83 9-month-old transgeni

Nod factors are lipochitooligosaccharides (LCOs) secreted by rhizobia. Nod factors trigger the nodulation programme in a compatible host. A bioassay was set up to test how crude (NGR234) and purified (NodS) Nod factors influence cell division and som

Lignin content and composition are important traits in several tree breeding programs, but very little is known about their natural variation. This study compares the lignin content in 1-year-old plants and 9-year-old trees of Norway spruce belonging

Plant embryogenesis is intimately associated with programmed cell death. The mechanisms of initiation and control of programmed cell death during plant embryo development are not known. Proteolytic activity associated with caspase-like proteins is pa

Development of multiple embryos from a single zygote, the phenomenon called monozygotic polyembryony, is a widespread reproductive strategy found in higher plants and especially in gymnosperms. The enigma of plant monozygotic polyembryony is that onl

The potential to use somatic embryos for large-scale propagation of elite genotypes, for integration into breeding programmes and for connecting breeding and mass propagation, is receiving much attention. However, before the methods are applied it is

In the animal life cycle, the earliest manifestations of programmed cell death (PCD) can already be seen during embryogenesis. The aim of this work was to determine if PCD is also involved in the elimination of certain cells during plant embryogenesi

A particle inflow gun enabled efficient production of transgenic plantlets of Picea abies from embryogenic suspension cultures. In transient assays, the Zea ubiquitin promoter was 12-16 times as active as the 35S promoter. For stable transformation,

Matured somatic embryos of different embryogenic cell lines of Picea abies formed as a response to abscisic acid and polyethylene glycol were categorised into three main groups: well-developed, less-developed and undeveloped type. Only the well-devel

The activity of six different promoter-gus (uidA) binary plasmid constructs has been analysed in transgenic roots of Pinus contorta, Nicotiana tabacum, Lycopersicon esculentum and Arabidopsis thaliana. Transgenic roots were induced by infection with
