Phloem water isotopically different to xylem water: Potential causes and implications for ecohydrological tracing

The stable isotopes of hydrogen and oxygen in xylem water are often used to investigate tree water sources. But this traditional approach does not acknowledge the contribution of water stored in the phloem to transpiration and how this may affect xylem wat ...

Phenotypic plasticity versus ecotypic differentiation under recurrent summer drought in two drought-tolerant pine species

Christoph Bachofen

Despite worldwide reports of high tree mortality, growing evidence indicates that many tree species are well adapted to survive repeated dry spells. The drought resilience of trees is related to their phenotypic plasticity and ecotypic differentiation. Whe ...

Bioethanol Production from Sugarcane Green Harvest Residues Using Auxin-Assisted Pretreatment

Edgard Gnansounou, Jegannathan Kenthorai Raman

Bioethanol and biochemicals from agriculture residues are key alternative for transport fuels and fossil chemicals to environmental impact mitigation and rural economy. In biofuels and biochemicals production, pretreatment is the crucial and energy demandi ...

Tree root systems competing for soil moisture in a 3D soil–plant model

Gabriele Manoli, Sara Bonetti, Gabriel George Katul

Competition for water among multiple tree rooting systems is investigated using a soil–plant model that accounts for soil moisture dynamics and root water uptake (RWU), whole plant transpiration, and leaf-level photosynthesis. The model is based on a numer ...

Phytochrome interacting factors 4 and 5 control seedling growth in changing light conditions by directly controlling auxin signaling

Jacques Rougemont, Ioannis Xenarios, Christian Fankhauser

Plant growth is strongly influenced by the presence of neighbors that compete for light resources. In response to vegetational shading shade-intolerant plants such as Arabidopsis display a suite of developmental responses known as the shade-avoidance syndr ...

Evaluating Ecohydrological Theories of Woody Root Distribution in the Kalahari

Paolo d'Odorico

The contribution of savannas to global carbon storage is poorly understood, in part due to lack of knowledge of the amount of belowground biomass. In these ecosystems, the coexistence of woody and herbaceous life forms is often explained on the basis of be ...

Exclusion of root competition increases competitive abilities of subordinate plant species through root-shoot interactions

Alexandre Buttler, Pierre Rémi Mariotte, Charlotte Vandenberghe, Aurélie Thébault

Questions What is the importance of root competition in the competitive abilities of dominant and subordinate species? Location Pair-wise greenhouse experiment based on field data from a semi-natural grassland community in the Swiss Jura Mountains (Col du ...

Genome-Wide Evaluation of Histone Methylation Changes Associated with Leaf Senescence in Arabidopsis

Nishanth Ulhas Nair

Leaf senescence is the orderly dismantling of older tissue that allows recycling of nutrients to developing portions of the plant and is accompanied by major changes in gene expression. Histone modifications correlate to levels of gene expression, and this ...

La station de biologie marine de Roscoff, un campus les pieds dans l'eau. ; Projet d'agrandissement (Département du Finistère, Bretagne, France)

Yann Christen

C'est à l'endroit même où les terres de la Bretagne maraîchère rencontrent les eaux tumultueuses de la Manche que s'établit Roscoff, petite cité littorale. Bastion des pionniers de la thérapie marine, elle est aussi le lieu de pèlerinage des naturalistes d ...

Dynamics of wetland vegetation under multiple stresses: a case study of changes in sawgrass trait, structure, and productivity under coupled plant-soil- microbe dynamics

Andrea Rinaldo

This paper quantifies wetland vegetation dynamics under drought, waterlogging, shading, and nutrient stresses within the coupled plant-soil-microbe system. A plant is characterized by three independent traits, namely leaf nitrogen (N) content, specific lea ...
