Plants face temporal and spatial variation in nitrogen (N) availability. This includes heterogeneity soil nitrate (NO3 −) content. To overcome these constraints, plants modify their gene expression physiological processes to optimize N acquisition. plasticity relies on a complex long-distance root-shoot-root signaling network that remains poorly understood. We previously showed cytokinin (CK) biosynthesis is required trigger systemic signaling. Here, we performed split-root experiments used...
Cells maintain a constant dialog between the extracellular matrix and their plasma membrane to fine tune signal transduction processes. We found that receptor kinase FERONIA (FER), which is proposed cell wall sensor, modulates phosphatidylserine accumulation nano-organization, key regulator of Rho GTPase signaling in Arabidopsis. demonstrate FER required for both Rho-of-Plant 6 (ROP6) nano-partitioning at downstream production reactive oxygen species upon hyperosmotic stimulus. Genetic...
Nitrogen fixation in the legume-rhizobium symbiosis is a crucial area of research for more sustainable agriculture. Our knowledge plant cascade response to perception bacterial Nod factors has increased recent years. However, discovery that are not involved Aeschynomene-Bradyrhizobium spp. interaction suggests alternative molecular dialogues may exist legume family. We evaluated conservation signaling pathway common other endosymbioses using three candidate genes: Ca2+/Calmodulin-Dependent...
Numerous reports have shown that various rhizobia can interact with non-host plant species, improving mineral nutrition and promoting growth. To further investigate the effects of such interactions on root development functions, we inoculated Arabidopsis thaliana model nitrogen fixing rhizobacterium Mesorhizobium loti (strain MAFF303099). In vitro, show colonization by M. remains epiphytic cells preferentially grow at sites where primary secondary roots intersect. Besides resulting in an...
Arabidopsis VASCULATURE COMPLEXITY AND CONNECTIVITY (VCC) is a plant-specific transmembrane protein that controls the development of veins in cotyledons. Here, we show expression and localization auxin efflux carrier PIN-FORMED1 (PIN1) altered vcc developing cotyledons overexpression PIN1-GFP partially rescues vascular defects dosage-dependent manner. Genetic analyses suggest VCC PINOID (PID), kinase regulates PIN1 polarity, are both required for PIN1-mediated control vasculature...
ABSTRACT Plants are subjected to variable nitrogen (N) availability including frequent spatial nitrate (NO 3 - ) heterogeneity in soil. Thus, plants constantly adapt their genome expression and root physiology order optimize N acquisition from this heterogeneous source. These adaptations rely on a complex long-distance root-shoot-root signaling network that is still largely unknown. Here, we used combination of reverse genetics, transcriptomic analysis, NO uptake experiments hormone...
