A human liver cDNA library enriched for full-length clones was screened for plasminogen cDNA using a synthetic 24-nucleotide probe derived from a reported partial cDNA sequence. 12 positive clones were identified and one of these was characterized in detail. The 2.7 kb insert contains the complete coding region. At 5 positions, it gives residues different(More)
Transgenic lines of hybrid aspen with elevated levels of gibberellin (GA) show greatly increased numbers of xylem fibres and increases in xylem fibre length. These plants therefore provide excellent models for studying secondary growth. We have used cDNA microarry analysis to investigate how gene transcription in the developing xylem is affected by(More)
Two different insulin-like growth-factor (IGF)-binding proteins have been found in human blood, one of high molecular mass and dependent on growth hormone for synthesis, the other of low molecular mass and independent of growth hormone. The small IGF-binding protein is abundant in human amniotic fluid. Its amino acid sequence has now been determined by(More)
Bioactive gibberellins (GAs) are known regulators of shoot growth and development in plants. In an attempt to identify where GAs are formed, we have analyzed the expression patterns of six GA biosynthesis genes and two genes with predicted roles in GA signaling and responses in relation to measured levels of GAs. The analysis was based on tangential(More)
To broaden our understanding of gibberellin (GA) biosynthesis and the mechanism whereby GA homeostasis is maintained in plants, we have investigated the degree to which the enzyme GA 3-oxidase (GA3ox) limits the formation of bioactive GAs in elongating shoots of hybrid aspen (Populus tremula x Populus tremuloides). We describe the cloning of a hybrid aspen(More)
