Aspen micropropagation: use for phytoremediation of soils
Selected elite Populus tremula and Populus tremula x Populus tremuloides mature trees growing in polluted areas were used for micropropagation. After sterilization of dormant buds, shoot tips were extirpated and cultured on nutrient media. MS medium with BAP (1.0 mg/L) and IBA (0.1 mg/L) showed to b...

Summary: | Selected elite Populus tremula and Populus tremula x Populus tremuloides mature trees growing in polluted areas were used for micropropagation. After sterilization of dormant buds, shoot tips were extirpated and cultured on nutrient media. MS medium with BAP (1.0 mg/L) and IBA (0.1 mg/L) showed to be suitable for organogenesis induction, whereas MS medium with BAP (0.2 mg/L) and glutamine (100 mg/L) was used for multiplication. A high number of adventitious shoots (20-30) was produced per multi-apex culture. Twenty-five clones were established in the gene bank. Four gene constructs of Agrobacterium tumefaciens comprising different promoters were used for transformations of aspen hybrid stem segments (bearing two genes, NPTII coding resistance to kanamycin, and GUS coding glucuronidase synthesis). The highest GUS activity was estimated in transformants with construct 148 controlled by promoter CAMV 35S. |
