A gene designated swin1.1 has been isolated by screening a Salix viminalis genomic library with a heterologous probe, win3 from Populus. The region sequenced included the entire coding sequence for a protein with 199 amino acids plus the promoter and terminator. At the 5' end of the coding region is
Salix psammophila is a desert shrub willow that has extraordinary adaptation to abiotic stresses and plays an important role in maintaining local ecosystems. Moreover, S. psammophila is regarded as a promising biomass feedstock because of its high biomass yields and short rotation coppice cycle.
The natural abundance of the nitrogen isotope 15, δ15N, was analysed in leaves of 23 subarctic vascular plant species and two lichens from a tree-line heath at 450 m altitude and a fellfield at 1150 m altitude close to Abisko in N. Sweden, as well as in soil, rain and snow. The aim was to reveal if
