Difference in astringency of the main pea protein fractions
Francesco Stellacci, Hanna Fanny Clarisse Lesme
Interactions between food and saliva govern complex mouthfeel perceptions such as astringency. Herein, we present a study of the interactions of salivary proteins with the main pea protein fractions that are obtained by isoelectric and salt precipitation ( ...
London2023RNA 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 ...
MDPI2022Global Soil Hydraulic Properties dataset based on legacy site observations and robust parameterization
The representation of land surface processes in hydrological and climatic models critically depends on the soil water characteristics curve (SWCC) that defines the plant availability and water storage in the vadose zone. Despite the availability of SWCC da ...
2022Plant wax and carbon isotope response to heat and drought in the conifer Juniperus monosperma
Plant waxes, including n-alkanes, are commonly used for a wide range of paleo-applications. Several common traits of n-alkanes that are used as paleo-proxies include chain length distribution and average chain length (ACL), as well as plant wax carbon and ...
2021Structural basis for recognition of RALF peptides by LRX proteins during pollen tube growth
Plant reproduction relies on the highly regulated growth of the pollen tube for sperm delivery. This process is controlled by secreted RALF signaling peptides, which have previously been shown to be perceived by Catharanthus roseus RLK1-like (CrRLK1Ls) mem ...
NATL ACAD SCIENCES2020The response of stomatal conductance to seasonal drought in tropical forests
Stomata regulate CO2 uptake for photosynthesis and water loss through transpiration. The approaches used to represent stomatal conductance (g s) in models vary. In particular, current understanding of drivers of the variation in a key parameter in those mo ...
2020Genetic variation and evolutionary history of a mycorrhizal fungus regulate the currency of exchange in symbiosis with the food security crop cassava
Most land plants form symbioses with arbuscular mycorrhizal fungi (AMF). Diversity of AMF increases plant community productivity and plant diversity. For decades, it was known that plants trade carbohydrates for phosphate with their fungal symbionts. Howev ...
2020Inhibition of mitophagy drives macrophage activation and antibacterial defense during sepsis
Mitochondria have emerged as key actors of innate and adaptive immunity. Mitophagy has a pivotal role in cell homeostasis, but its contribution to macrophage functions and host defense remains to be delineated. Here, we showed that lipopolysaccharide (LPS) ...
AMER SOC CLINICAL INVESTIGATION INC2020Effects of Sphagnum Leachate on Competitive Sphagnum Microbiome Depend on Species and Time
Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, Bjorn Jozef Maria Robroek, Samuel Thomas Gabriel Hamard
Plant specialized metabolites play an important role in soil carbon (C) and nutrient fluxes. Through anti-microbial effects, they can modulate microbial assemblages and associated microbial-driven processes, such as nutrient cycling, so to positively or ne ...
2019Linking 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 ...
