In vivo X-ray microtomography locally affects stem radial growth with no immediate physiological impact

Pascal Turberg, Charlotte Grossiord, Hervé Cochard, Laura Mekarni

Microcomputed tomography (mu CT) is a nondestructive X-ray imaging method used in plant physiology to visualize in situ plant tissues that enables assessments of embolized xylem vessels. Whereas evidence for X-ray-induced cellular damage has been reported, ...

Selecting Suitable Near-Native Lignins for Research

Jeremy Luterbacher

There are several methods to isolate near-native lignins, including milled-wood lignin, enzymatic lignin, cellulolytic enzyme lignin, and enzymatic mild-acidolysis lignin. Which one is the most representative of the native lignin? Herein, near-native ligni ...

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 ...

Warming may extend tree growing seasons and compensate for reduced carbon uptake during dry periods

Charlotte Grossiord, Christoph Bachofen, Yann Vitasse, Eugénie Isabelle Mas, Margaux Clara Lou Didion-Gency

Warming and drought alter plant phenology, photosynthesis and growth with important consequences for the global carbon cycle and the earth’s climate. Yet, few studies have attempted to tease apart their effects on tree phenology, particularly leaf senes ...

Engineering synthetic adhesins for biophysical investigation and rewiring of host-microbe interactions

Xavier Jean-Yves Pierrat

Host attachment is often a critical step in the onset of pathogenesis. To attach to host cells, bacteria have evolved a range of adhesins that bind to specific receptors. Some of these adhesins have been thoroughly characterized using biochemical technique ...

Blocking probability of large wood and resulting head increase at ogee crest spillways

Paloma Furlan

Large wood increases the hydraulic complexity of rivers, yet it may block and modify the flood discharge capacity of hydraulic structures such as bridges and spillways. When spillway blockage occurs, dangerous and hazardous situations have been observed at ...

Effect of mechanical damage and wound healing on the viscoelastic properties of stems of flax cultivars (Linum usitatissimum L. cv. Eden and cv. Drakkar)

Véronique Michaud, Sara Dalle Vacche, Federica Sordo

As plant fibres are increasingly used in technical textiles and their composites, underlying principles of wound healing in living plant fibres are relevant to product quality, and provide inspiration for biomimetic healing in synthetic materials. In this ...

Oriented MFI membranes by gel-less secondary growth of sub-100 nm MFI-nanosheet seed layers

Kumar Varoon Agrawal, Han Zhang

A zeolite membrane fabrication process combining 2D-zeolite nanosheet seeding and gel-free secondary growth is described. This process produces selective molecular sieve films that are as thin as 100 nm and exhibit record high permeances for xylene- and bu ...

Homogenization of a multiscale viscoelastic model with nonlocal damping, application to the human lungs

Paul Isaac Denis Louis Marie Cazeaux

We are interested in the mathematical modeling of the deformation of the human lung tissue, called the lung parenchyma, during the respiration process. The parenchyma is a foam-like elastic material containing millions of air-filled alveoli connected by a ...

Influence of root characteristics and soil variables on the uprooting mechanics of Avena sativa and Medicago sativa seedlings

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier, Paolo Burlando

The success of seedlings and rejuvenated woody debris growing on river bedforms depends on the resistance to uprooting by flow provided by their simple root architecture. Avena sativa and Medicago sativa seedlings were used in flume experiments as prototyp ...
