Deciphering composition and function of the root microbiome of a legume plant
BACKGROUND Diverse assemblages of microbes colonize plant roots and collectively function as a microbiome. Earlier work has characterized the root microbiomes of numerous plant species, but little information is available for legumes despite their key role in numerous ecosystems including agricultural systems. Legumes form a root nodule symbiosis with nitrogen-fixing Rhizobia bacteria and there...
متن کاملPLANT MICROBIOME. Salicylic acid modulates colonization of the root microbiome by specific bacterial taxa.
Immune systems distinguish "self" from "nonself" to maintain homeostasis and must differentially gate access to allow colonization by potentially beneficial, nonpathogenic microbes. Plant roots grow within extremely diverse soil microbial communities but assemble a taxonomically limited root-associated microbiome. We grew isogenic Arabidopsis thaliana mutants with altered immune systems in a wi...
متن کاملRoot surface as a frontier for plant microbiome research.
Plants associate—analogous to animals or us humans—with a multitude of microorganisms, which collectively function as a microbiome. A major discovery of the last decade is that numerous organisms of a microbiome (aka microbiota) are not unpretentious background actors. Instead, some microbiota members influence host processes including behavior, appetite, and health in animals (1) and contribut...
متن کاملPlant root tortuosity: an indicator of root path formation in soil with different composition and density
BACKGROUND AND AIMS Root soil penetration and path optimization are fundamental for root development in soil. We describe the influence of soil strength on root elongation rate and diameter, response to gravity, and root-structure tortuosity, estimated by average curvature of primary maize roots. METHODS Soils with different densities (1·5, 1·6, 1·7 g cm-3), particle sizes (sandy loam; coarse...
متن کاملGetting to the root of plant biology: impact of the Arabidopsis genome sequence on root research.
Prior to the availability of the genome sequence, the root of Arabidopsis had attracted a small but ardent group of researchers drawn to its accessibility and developmental simplicity. Roots are easily observed when grown on the surface of nutrient agar media, facilitating analysis of responses to stimuli such as gravity and touch. Developmental biologists were attracted to the simple radial or...
