On the air permeability of Populus pit [PDF]

Computer Methods in Biomechanics and Biomedical Engineering, 2012
Sap hydrodynamics in vascular cells of trees seems to be controlled by small membranes called pits. Understanding how the pit junctions regulate the sap flow and stop embolism by cavitation is today a challenging issue. The hypothesis that the pit porosity adjusts the flow under negative pressure and stops the air bubble diffusion need to be validated.

Anthocyanins of the anthers as chemotaxonomic markers in the genus Populus L.. Differentiation between Populus nigra, Populus alba and Populus tremula [PDF]

Phytochemistry, 2016
Three main species of Popululs L. (Salicaceae) have been reported to occur in the Iberian Peninsula: Populus nigra L., Populus alba L. and Populus tremula L. The degree of pilosity of the bracts of the male catkins is a key character for their differentiation. The anthers of these poplar species possess anthocyanins that provide them a red colouration.

miR172-AP2 Controls Age-Dependent Regeneration Competence in Populus. [PDF]

Plant Biotechnol J
ABSTRACT Plants maintain remarkable regenerative potential, yet this capacity declines with developmental age, limiting clonal propagation and biotechnological applications. Here, we show that the miR172‐AP2 module serves as a central determinant of regeneration competence in Populus.

The transcriptome of Populus in elevated CO2 reveals increased anthocyanin biosynthesis during delayed autumnal senescence [PDF]

, 2010
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

Rapidly evolving genes and stress adaptation of two desert poplars, Populus euphratica and P. pruinosa [PDF]

, 2013
Understanding which genes have evolved rapidly with the recent tree speciation in arid habitats can provide valuable insights into different adaptation mechanisms. We employed a comparative evolutionary analysis of expressed sequence tags (ESTs) from two

Commodity risk assessment of Populus alba, Populus nigra and Populus tremula plants from the UK [PDF]

EFSA Journal
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers plant health risks posed by plants of Populus alba, Populus nigra and ...

Agrobacterium-Mediated Stable Genetic Transformation of Populus angustifolia and Populus balsamifera [PDF]

Frontiers in Plant Science, 2016
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.
