Homéostasie des ions cuivre et fer au cours de la germination fongique. [PDF]
, 2019 La germination fongique est un processus cellulaire qui coordonne les changements métaboliques et morphologiques permettant à une spore en dormance de retrouver une forme végétative et une croissance mitotique. Les spores doivent jauger adéquatement leur

Plant, Cell &Environment, EarlyView.ABSTRACT Salinity stress disrupts rhizosphere homoeostasis and inhibits root development. Although PGPR are known to alleviate such stress, critical knowledge gaps remain regarding the specific mechanisms by which they enhance tolerance under moderate to high salinity, particularly within the wheat rhizosphere ‐root interface.

Bioalteration de verres basaltiques modèles : impact des sidérophores et rôle du fer [PDF]
, 2015 The alteration of ocean basalts partly controls the composition of seawater and of the oceanic crust which in turn influences the Earth's mantle geochemistry and may also have a significant impact on Earth's climate over a geological timescale. Regarding

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families
Plant, Cell &Environment, EarlyView.ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Etude du rôle des sidérophores microbiens dans la modulation des défenses de la plante Arabidopsis thaliana [PDF]
, 2014 Iron is an essential element for almost all living organisms, however, it is not bioavailable and is toxic in its free form as it generates reactive oxygen species via the Fenton reaction.
