6. Induction and development of adventitious bud primordia on embryos, buds and needles of Norway spruce (Picea abies (L.) Karst.) grown in vitro

7. Molecular mechanisms regulating early cone development in Norway spruce Picea abies (Karst)
Sammanfattning : Flower development progress through distinct phases that are controlled by complex genetic networks, which in turn are regulated by both endogenous and exogenous factors. A large number of functional studies have been conducted over the past decades to understand the genetic networks that regulate flower development in angiosperm model species. LÄS MER
8. Planting and survivability of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) in Sweden : Questions of seedling storability, site preparation, bud burst timing and freezing tolerance
Sammanfattning : The non-native Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) has been grown to a limited extent in the southern part of Sweden since the early 1900s. A more extensive use has probably been curtailed by its known susceptibility to damage by frost, pine weevil and other pests. LÄS MER
9. Transcriptional regulation of thyroid development possible interplay of endoderm- and mesoderm-derived morphogenetic signals
Sammanfattning : Congenital hypothyroidism (CH) affects 1 in 3000 children and is the major cause of treatable mental retardation. Most cases are due to malformations of the gland, collectively named thyroid dysgenesis. The disease results from defective thyroid organogenesis during embryonic life. LÄS MER
10. Genetic analysis of ligand-receptor interactions in the TGF-beta superfamily during early embryonic development
Sammanfattning : During early development, cells differentiate and acquire specific fates according to their position in concentration gradients of morphogens. These substances often spread from a local region, termed an organizer, and exert different effects at distinct thresholds. LÄS MER
