Interactions between beech and oak seedlings can modify the effects of hotter droughts and the onset of hydraulic failure

Charlotte Grossiord, Eugénie Isabelle Mas, Janisse Deluigi, Margaux Clara Lou Didion-Gency

center dot Mixing species with contrasting resource use strategies could reduce forest vulnerability to extreme events. Yet, how species diversity affects seedling hydraulic responses to heat and drought, including mortality risk, is largely unknown. Using ...

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

Andrea Rinaldo, Paolo Benettin

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 ...

OsCAldOMT1 is a bifunctional O-methyltransferase involved in the biosynthesis of tricin-lignins in rice cell walls

Wu Lan

Lignin is a phenylpropanoid polymer produced in the secondary cell walls of vascular plants. Although most eudicot and gymnosperm species generate lignins solely via polymerization of p-hydroxycinnamyl alcohols (monolignols), grasses additionally use a fla ...

Is desiccation tolerance and avoidance reflected in xylem and phloem anatomy of two coexisting arid-zone coniferous trees?

Alessandra Patera

Plants close their stomata during drought to avoid excessive water loss, but species differ in respect to the drought severity at which stomata close. The stomatal closure point is related to xylem anatomy and vulnerability to embolism, but it also has imp ...

Impact of drought on the functioning of grassland systems

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra

A rainfall manipulation experiment was conducted over a two-year period on two semi-natural grassland sites, in order to determine the effects of drought on both forage production (dry matter and nutritive value) and plant-soil relationships. Water stress ...

Peatland vascular plant functional types affect dissolved organic matter chemistry

Alexandre Buttler, Vincent Eric Jules Jassey, Luca Bragazza, Bjorn Jozef Maria Robroek, Remy Jean Henry Albrecht, Adrian Pulgarin, Samuel Thomas Gabriel Hamard

Northern peatlands are large repositories of carbon. Peatland vascular plant community composition has been functionally associated to a set of biogeochemical processes such as carbon cycling. Yet, we do not fully understand to what extent vascular plant f ...

Environmental drivers of carbon and nitrogen isotopic signatures in peatland vascular plants along an altitude gradient

Alexandre Buttler, Luca Bragazza, Konstantin Svetlozarov Gavazov

Peatlands are important sinks of atmospheric carbon (C) that, in response to climate warming, are undergoing dynamic vegetation succession. Here we examined the hypothesis that the uptake of nutrients by different plant growth forms (PGFs) is one key mecha ...

Experimental warming interacts with soil moisture to discriminate plant responses in an ombrotrophic peatland

Alexandre Buttler, Vincent Eric Jules Jassey, Luca Bragazza, Pierre Rémi Mariotte, Bjorn Jozef Maria Robroek

QuestionA better understanding of the response of Sphagnum mosses and associated vascular plants to climate warming is relevant for predicting the carbon balance of peatlands in a warmer world. Open-top chambers (OTCs) have been used to investigate the eff ...

Plant functional diversity drives niche-size-structure of dominant microbial consumers along a poor to extremely rich fen gradient

Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

Plant community composition is recognized more and more for playing an important role in ecosystem processes, such as C cycling. In particular, plant functional type (PFT) composition seems to have a key regulatory role, yet the underlying mechanisms in ...

Biogeochemical plant-soil microbe feedback in response to climate warming in peatlands

Julien Parisod, Alexandre Buttler, Luca Bragazza

Peatlands act as global sinks of atmospheric carbon (C) through the accumulation of organic matter(1), primarily made up of decay-resistant litter of peat mosses(2). However, climate warming has been shown to promote vascular plant growth in peatlands, esp ...

Patterns of bryophyte and vascular plant richness in European subalpine springs

Alexandre Buttler, Lucia Sekulova

The diversity of spring habitats can be determined not only by local environmental conditions, but also by large-scale biogeographical effects. The effects can differ across various groups of organisms. We compared alpha-, beta- and gamma-diversity pattern ...

High nitrogen deposition alters the decomposition of bog plant litter and reduces carbon accumulation

Alexandre Buttler, Luca Bragazza

Bogs are globally important sinks of atmospheric carbon (C) due to the accumulation of partially decomposed litter that forms peat. Because bogs receive their nutrients from the atmosphere, the world-wide increase of nitrogen (N) deposition is expected to ...

Over-expression of PHO1 in Arabidopsis leaves reveals its role in mediating phosphate efflux

Michaël Bensimon

P>Inorganic phosphate (Pi) homeostasis in multi-cellular eukaryotes depends not only on Pi influx into cells, but also on Pi efflux. Examples in plants for which Pi efflux is crucial are transfer of Pi into the xylem of roots and release of Pi at the peri- ...
