Carefully managed tree plantations offer an opportunity for sustainable biomass production. In recent years, the responses of the Salicaceae to environmental constraints have increasingly been investigated at different levels of biological integration, giving rise to a physiological approach to the function of trees in environmental restoration and monitoring. Significant progress has been achieved by the poplar and willow community in understanding targeted characteristics of complex tree…

Shaping the multifunctional tree: the use of Salicaceae in environmental restoration

This review is a timely account of the questions related to phytotechnology in shaping the multifunctional tree, particularly with regard to tree responses to environmental pollution, and hopes it will stimulate further studies in this interesting area of tree biology.

Using Populus as a lignocellulosic feedstock for bioethanol

This work reviews economically important traits relevant for intensively managed biofuel crop plantations, genomic and phenotypic resources available for Populus, breeding strategies for forest trees dedicated to bioenergy provision, and bioprocesses and downstream applications related to opportunities using Salicaceae as a renewable resource.

Leaf Morphology Variation of Populus nigra L. in Natural Populations along the Rivers in Croatia and Bosnia and Herzegovina

Significant differences have been determined between the typical and the hairy type of European black poplar in the studied morphological traits and these dissimilarities are in accordance with the climatic differences in respective habitats of continental riparian forests and the Submediterranean type of climate.

Effects of combined ozone and cadmium stresses on leaf traits in two poplar clones

Although Cd and O3 are known to share some common toxicity pathways, the combined effects induced distinct clone-specific responses, underlying the complexity of plant reactions to multiple stresses.

Differential ozone sensitivity interferes with cadmium stress in poplar clones

The overall data indicate that Cd and O3 induced clone specific responses and when they were applied in combination, antagonistic rather than synergistic effects were observed.

Community genetics in the time of next‐generation molecular technologies

A variety of ‘‐omics’ tools are introduced, with recent studies of plant–insect herbivores and of ectomycorrhizal systems providing detailed examples of how next‐generation approaches can revolutionize the authors' understanding of interspecific interactions.

Molecular characterization of some lignicolous species from fungal culture collection

Results from analysing ITS1 region sequences obtained from fungal DNA of culture collection of autochthonous, lignicolous genera Piptoporus, Pleurotus, Ganoderma and Schizophyllum indicated small intra-species variability of ITS1 area and pointed to it as an ideal marker for verification of fungal culture collections' authenticity.

Growth Trajectory Modeling for a Full-Sib Pedigree of Salix suchouenesis

In this study, we measured the growth increments periodically for 450 progeny in a fully sib family of the annually harvesting basket willow (S. suchouensis). By testing with different non-linear



Intensive short rotation forestry in boreal climates: present and future perspectives

Short rotation forestry (SRF) is regarded as a silvicultural practice employing high-density plantations of fast-growing tree species on fertile land with a rotation period of fewer than 10-12 years.

Do tree-ring traits reflect different water deficit responses in young poplar clones (Populus × canadensis Mönch ‘I-214’ and P. deltoides ‘Dvina’)?

‘Dvina’ has the potential to recover promptly after drought stress, but at the expense of poor wood technological properties, while ‘I-214’ could continue to grow more uniformly under limited water availability, though at a lower rate.

Low temperature induces different cold sensitivity in two poplar clones (Populus x canadensis Monch 'I-214' and P. deltoides Marsh. 'Dvina').

Automatic point dendrometers were confirmed to be a reliable non-invasive method for testing the sensitivity of diameter variation to cold temperature and showed that 'I-214' was more sensitive to low air temperatures than 'Dvina'.

Growth, physiological and molecular traits in Salicaceae trees investigated for phytoremediation of heavy metals and organics.

This review shows the recent improvements in analytical tools based on the identification of useful genetic diversity associated with classical growth, physiological and biochemical traits, and the importance of plant genotype selection for enhancing phytoremediation efficiency.

Can forest trees compensate for stress-generated growth losses by induced production of volatile compounds?

Recent advances in the understanding of stress-induced VOC emissions from trees, with special focus on Populus spp.

Early effects of water deficit on two parental clones of Populus nigra grown under different environmental conditions

Clone 58–861 seems to increase the permeability of the vascular tissue by overexpressing aquaporin genes, probably in order to facilitate water transport, and Poli appears to increase water conservation in the root cells by downregulating aquaporins.

Populus: a model system for plant biology.

The relatively close phylogenetic relationship of Populus to Arabidopsis in the Eurosid clade of Eudicotyledonous plants aids in comparative functional studies and comparative genomics, and has the potential to greatly facilitate studies on genome and gene family evolution in eudicots.

Intraspecific variation of physiological and molecular response to cadmium stress in Populus nigra L.

Results suggest that the glutathione pathway is involved in the differential Cd tolerance of the two genotypes of Populus nigra, a valuable resource for understanding tolerance to Cd and for selection of plant material for phytoremediation.

Responses of Populus deltoides × Populus nigra (Populus × euramericana) clone I-214 to high zinc concentrations.

It is concluded that poplar plants have the potential to be used for plantations in Zn-contaminated soils, in the range of tested Zn concentrations.

Spatial distribution of cadmium in leaves and its impact on photosynthesis: examples of different strategies in willow and poplar clones.

Results showed that SS5 had the highest leaf Cd concentration and high gas exchange activity similar to that of Poli, which had the lowestCd concentration, and Phytochelatins (PCs) were not detected in SS5, while their concentration was high in both Poli and A4A.
