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

Charlotte Grossiord, Pascal Turberg, 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, ...

Water use efficiency: A review of spatial and temporal variability

Gabriele Manoli, Sara Bonetti

Water Use Efficiency (WUE) expresses the trade-off between carbon assimilation (or subsequent carbon storage) and water release, two concurrent gas fluxes essential for plant functioning. Here, we review metrics that have been introduced to quantify WUE ac ...

Mechanistic 2D flow-erosion modelling of vegetated river banks

Giovanni De Cesare, Paolo Perona

We present a simple, vertically-explicit 2D model of river bank erosion that also takes the effect of sediment stabilization by plant roots into account. The model is solved in quasi-analytical form for an exemplary non-stationary hydrograph temporal signa ...

Understanding the mechanisms of non-thermal plasma treatments on seeds

Alexandra Waskow

The motivation driving plasma-seed treatment research is the renewed importance of sustainable, eco-friendly agriculture. There is a constant interest in finding alternatives to minimize resource use and environmental degradation, while ensuring healthy se ...

Emotion Recognition in a Multi-Componential Framework: The Role of Physiology

Gelareh Mohammadi, Maëlan Quentin Menétrey

The Component Process Model is a well-established framework describing an emotion as a dynamic process with five highly interrelated components: cognitive appraisal, expression, motivation, physiology and feeling. Yet, few empirical studies have systematic ...

Time Dependent Image Generation of Plants from Incomplete Sequences with CNN-Transformer

Marc Conrad Russwurm

Data imputation of incomplete image sequences is an essential prerequisite for analyzing and monitoring all development stages of plants in precision agriculture. For this purpose, we propose a conditional Wasserstein generative adversarial network TransGr ...

Method for labelling a device and devices obtanaible therefrom

Florian Dylan Fallegger, Nicolas Vachicouras, Ludovic Serex, Benoit Rémi Dominique Huguet

Disclosed herein is a method for labelling a portion of a device, said method comprising the steps of providing a first substrate layer of a transparent or translucent material, depositing a first coloured material onto said first substrate layer in a labe ...

Emotion Recognition in a Multi-Componential Framework: The Role of Physiology

Gelareh Mohammadi

Emotions are rich and complex experiences involving various behavioral and physiological responses. While many empirical studies have focused on discrete and dimensional representations of emotions, these representations do not fully reconcile with recent ...

RNA Sequencing of Arabidopsis thaliana Seedlings after Non-Thermal Plasma-Seed Treatment Reveals Upregulation in Plant Stress and Defense Pathways

Ivo Furno, Alan Howling, Alexandra Waskow

Not all agricultural practices are sustainable; however, non-thermal plasma treatment of seeds may be an eco-friendly alternative to improve macroscopic plant growth parameters. Despite the numerous successful results of plasma-seed treatments reported in ...

Conditions for the emergence of circumnutations in plant roots

Dario Floreano, Ilya Loshchilov

The plant root system shows remarkably complex behaviors driven by environmental cues and internal dynamics, whose interplay remains largely unknown. A notable example is circumnutation growth movements, which are growth oscillations from side to side of t ...

On the use of leaf water to determine plant water source: A proof of concept

Paolo Benettin

Source water apportionment studies using the dual isotopes of oxygen and hydrogen have revolutionized our understanding of ecohydrology. But despite these developments-mostly over the past decade-many technical problems still exist in terms of linking xyle ...

Foliar respiration is related to photosynthetic, growth and carbohydrate response to experimental drought and elevated temperature

Charlotte Grossiord

Short-term plant respiration (R) increases exponentially with rising temperature, but drought could reduce respiration by reducing growth and metabolism. Acclimation may alter these responses. We examined if species with different drought responses would d ...

Plant Terpenes on Treating Cardiovascular and Metabolic Disease: A Review

Rodrigo Araujo Fraga Da Silva

The use of medicinal plants as a therapy alternative is old as human existence itself. Nowadays, the search for effective molecules for chronic diseases treatments has increased. The cardiometabolic disorders still the main cause of death worldwide and pla ...

Plant responses to rising vapor pressure deficit

Charlotte Grossiord

Recent decades have been characterized by increasing temperatures worldwide, resulting in an exponential climb in vapor pressure deficit (VPD). VPD has been identified as an increasingly important driver of plant functioning in terrestrial biomes including ...

Real-time optimization of load sharing for gas compressors in the presence of uncertainty

Dominique Bonvin, Timm Faulwasser, Alejandro Gabriel Marchetti, Predrag Milosavljevic

This paper investigates the problem of load-sharing optimization of gas compressors in the presence of uncertainty. The objective is to operate a set of compressor units in an energy-efficient way, while at the same time meeting a varying load demand. The ...

Tree water deficit and dynamic source water partitioning

Andrea Rinaldo, Paolo Benettin, Mitra Asadollahi

The stable isotopes of hydrogen and oxygen (delta H-2 and delta O-18, respectively) have been widely used to investigate tree water source partitioning. These tracers have shed new light on patterns of tree water use in time and space. However, there are s ...

110th Anniversary: A Feature-Based Analysis of Static Real-Time Optimization Schemes

Dominique Bonvin

This paper addresses the steady-state optimization of continuous processes in the presence of uncertainty in the form of unknown or time-varying model parameters, structural plant-model mismatch, and disturbances. To address these issues, we assume that ce ...

Seasonal variability of groundwater level effects on the growth of Carex cinerascens in lake wetlands

Alexandre Buttler, Luca Bragazza, Pierre Rémi Mariotte, Mathieu Raymond Santonja, Wenjuan Feng

Groundwater level is crucial for wetland plant growth and reproduction, but the extent of its effect on plant growth can vary along with changed precipitation and temperature at different seasons. In this context, we investigated the effect of two groundwa ...

Linking soil's volatilome to microbes and plant roots highlights the importance of microbes as emitters of belowground volatile signals

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra, Richard Splivallo

Plants and microbes release a plethora of volatiles that act as signals in plant-microbe interactions. Characterizing soil's volatilome and microbiome might shed light on the nature of relevant volatile signals and on their emitters. This hypothesis was te ...
