Plant genotype, immunity and soil composition control the rhizosphere microbiome
… separate for all three generations. The microbiome community structure of the plant rhizosphere in each generation was characterised using ARISA DNA fingerprinting and 454 sequencing. Rhizosphere bacterial and fungal communities are different from those in bulk soil and there are also …

Metatranscriptomic analysis of community structure and metabolism of the rhizosphere microbiome.
Plant-microbe interactions in the rhizosphere, the region of soil influenced by plant roots, are integral to biogeochemical cycling, and maintenance of plant health and productivity. Interactions between model plants and microbes are well understood, but relatively little is about the plant …

Understanding Zea mays genetic influence on the structure and function of the rhizosphere microbiome
Assembly of the plant rhizosphere microbiome is driven by plant genetic and evolutionary history. Plant microbiomes play a major role in altering plant resilience, fitness, nutrition, and productivity. Plant hosts selectively filter microorganisms that colonize their rhizosphere. This selective …

Exploring candidate genes and rhizosphere microbiome in relation to iron cycling in Andean potatoes
… in the potato genome). The microorganisms in the rhizosphere react intensely with the various metabolites released by plant roots in a variety of ways such as positive, negative, and neutral. These interactions can influence the uptake and transport of micronutrients in the plant roots. Therefore, …

Defining functional microbiomes of wheat (Triticum aestivum) and maize (Zea mays), under regenerative management practices, in South Africa
Soil microbiomes are complex, interconnected assemblages of microorganisms that underpin fundamental ecosystem processes, including nutrient cycling, pathogen and drought resistance, and soil structural development. Despite their central role in ecosystem functioning, the dynamics of soil …

Unlocking the genetic potential of the root system, rhizosheath mucilage and microbiome of wheat (Triticum aestivum L.)
… inputs. To fill the knowledge gap on root-rhizosphere-yield interactions the research presented here falls into three strategic areas: root system architecture (RSA), root secretions and the rhizosphere microbiome. 1) Genetic mapping of RSA in the Avalon x Cadenza Doubled Haploid (AxC) …

Statistical methods for ChIP-seq and microbiome studies using next-generation DNA sequencing data
… sites. Chapters 3-4 are about analysis of microbiome data to estimate the causal effects of microbiome features on interesting outcomes in presence of confounding variables.</p> <p>ChIP-seq experiments aim to detect DNA-protein binding sites and require biological replication to draw …

The functional role of root-associated microbiome and metabolome of myrothamnus flabellifolia
… desiccation. Despite this, the role of the microbiome in desiccation tolerance, particularly in resurrection plants, remains a relatively unexplored area. Myrothamnus flabellifolia, a resurrection plant, stands out for its remarkable ability to endure severe desiccation, making it an ideal …

Exploring the impact of abiotic stress on Brassica and tomato: morphophysiology and microbiome dynamics [Analisi dell'impatto dello stress abiotico su Brassica e pomodoro: morfofisiologia e dinamiche del microbioma]
I cambiamenti climatici e la crescente domanda globale di alimenti rendono necessaria la creazione di specie vegetali resilienti agli stress abiotici e compatibili con pratiche agricole sostenibili. In questa tesi sono stati investigati due approcci complementari: la base genetica della tolleranza …
