Understanding the maturation stress and wood properties of poplar tension is critical for improving lumber yields utilization ratio. In this study, released longitudinal strains (RLMS), anatomical features, physical mechanical properties, nano-mechanical cell wall were analyzed at different peripheral positions heights in nine artificially inclined, 12-year-old (Populus × euramericana cv. ‘Zhon...

Two Gram-stain negative aerobic bacterial strains were isolated from the bark tissue of Populus × euramericana. The novel isolates were investigated using a polyphasic approach including 16S rRNA gene sequencing, genome sequencing, average nucleotide identity (ANI) and both phenotypic and chemotaxonomic assays. The genome core gene sequence and 16S rRNA gene phylogenies suggest that the novel i...

*The delay in autumnal senescence that has occurred in recent decades has been linked to rising temperatures. Here, we suggest that increasing atmospheric CO2 may partly account for delayed autumnal senescence and for the first time, through transcriptome analysis, identify gene expression changes associated with this delay. *Using a plantation of Populus x euramericana grown in elevated [CO2] ...

Poplar is a model system for the regeneration and genetic transformation of woody plants. To shorten the time required for studies of transgenic poplar, efforts have been made to optimize transformation methods that use Agrobacterium tumefaciens. In this study, an Agrobacterium infective suspension was treated at 4 °C for at least 10 h before infecting explants. By transforming the Populus hybr...

Wood from biomass plantations with fast growing tree species such as poplars can be used as an alternative feedstock for production of biofuels. To facilitate utilization of lignocellulose for saccharification, transgenic poplars with modified or reduced lignin contents may be useful. However, the potential impact of poplars modified in the lignification pathway on ectomycorrhizal (EM) fungi, w...
