Agrobacterium-Mediated Stable Genetic Transformation of Populus angustifolia and Populus balsamifera
The present study demonstrates Agrobacterium tumefaciens-mediated stable genetic transformation of two species of poplar - Populus angustifolia and Populus balsamifera. The binary vector pCAMBIA-Npro-long-Luc containing the luciferase reporter gene was used to transform stem internode and axillary bud explants. Putative transformants were regenerated on selection-free medium using our previousl...
متن کاملEfficient Agrobacterium-Mediated Transformation of Hybrid Poplar Populus davidiana Dode × Populus bollena Lauche
Poplar is a model organism for high in vitro regeneration in woody plants. We have chosen a hybrid poplar Populus davidiana Dode x Populus bollena Lauche. By optimizing the Murashige and Skoog medium with (0.3 mg/L) 6-benzylaminopurine and (0.08 mg/L) naphthaleneacetic acid, we have achieved the highest frequency (90%) for shoot regeneration from poplar leaves. It was also important to improve ...
متن کاملEfficient Agrobacterium-Mediated Transformation and Analysis of Transgenic Plants in Hybrid Black Poplar (Populus × euromericana Dode Guinier)
Black poplar (Populus× euramericana Dode Guinier) is an industrially important tree with broad applications in wood and paper, biofuel and cellulose-based industries as well as plant breeding programs and soil phytoremediation approaches. Here, we have focused on development of direct shoot regeneration and Agrobacterium-mediated transformation protocols using the in vitro internodal stem tissu...
متن کاملGC-MS analysis of compounds extracted from buds of Populus balsamifera and Populus nigra.
The composition of hexane and ether extracts from buds of two poplar species (Populus balsamifera and P. nigra) was investigated by GC-MS method. In hexane extracts, 54 "neutral" compounds were recorded. The greatest amounts of them are sesquiterpenes and n-alkanes. Among 56 components of ether extracts, many aliphatic acids and hydroxyacids were detected. However, the main fraction consists of...
متن کاملNucleotide diversity and linkage disequilibrium in balsam poplar (Populus balsamifera).
*Current perceptions that poplars have high levels of nucleotide variation, large effective population sizes, and rapid decay of linkage disequilibrium are based primarily on studies from one poplar species, Populus tremula. *We analysed 590 gene fragments (average length 565 bp) from each of 15 individuals from different populations from throughout the range of Populus balsamifera. *Nucleotide...
