Interplay between selenium hyperaccumulator plants and their microbiome
The plant microbiome includes all microorganisms that occur on the plant root (rhizosphere) and shoot (phyllosphere) or inside plants (endosphere). Many of these microbes benefit their host by promoting growth, helping acquire nutrients or by alleviating biotic or abiotic stress. In addition to its …

Elucidating the Molecular Pathways Involved in the Fitness and Water Stress Response of Pseudomonas synxantha 2-79 in the Plant Rhizosphere
… molecular adaptation of 2-79-like bacteria to plants growing in dry soils is poorly understood. We hypothesized that the ability of 2-79 to colonize and persist in the rhizosphere of water-stressed plants is underpinned by the formation of hydrating biofilms and the utilization of root exudates …

Host Specificity, Negative Feedbacks, and Pathogen Defense in the Plant Phyllosphere Microbiome
My dissertation research spans several topics in plant microbial ecology. In two research projects, I have explored whether host specificity influences fungal endophyte community structure in plant leaves across several ecotypes of switchgrass (Panicum virgatum) and across 19 plant species within …

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 …

Investigation of Miscanthus associated microbiome: effects of biotic and abiotic factors
… such as nitrogen-fixing bacteria, contribute to plant yield and fitness, representing under-explored plant nutrient sources. Optimizing the positive interactions between Miscanthus species and associated bacteria has high potential to support sustainable crop production. Bacterial community …

Exploring Interactions of Phyllosphere Epiphytes with Plant Pathogenic Bacteria Pseudomonas and Xanthomonas on Tomato
… the importance of resident microflora of plants in contributing towards overall plant health. Among difference components of the plant microbiome, <em>Methylobacterium</em> and <em>Sphingomonas</em> have been recognized as common residents of the <em>phyllosphere</em> for many host plants, …

BACTERIAL PLAYERS IN CROP SYSTEMS: BENEFITS AND RISKS IN THE " ONE HEALTH" PERSPECTIVES.
… microbes in agricultural systems is the use of plant beneficial strains (i.e., biofertilizer and biostimulants). Experiments were designed to better clarify the interactions occurring between bacteria inoculants and the recipient plant microbiome and, additionally, the research was focused on …

The functional role of root-associated microbiome and metabolome of myrothamnus flabellifolia
… four decades, extensive research on resurrection plants has yielded valuable insights into the mechanisms these plants employ to adapt during desiccation. Despite this, the role of the microbiome in desiccation tolerance, particularly in resurrection plants, remains a relatively unexplored area. …

Unearthing the mechanisms of the mycorrhizal-bacterial symbiosis in plant roots using a metatranscriptomic approach
… conserved symbiosis with a majority of land plants which provides plant hosts with increased capability for soil nutrient uptake. These endosymbiotic fungi are themselves colonized by a diverse group of bacteria, including both parasitic and symbiotic species. Recently several obligate …

Valorizzazione delle varietà autoctone di broccoli, cavolfiori e pomodori per l'innovazione di processo e di prodotto delle aree interne della Sicilia
Se da un lato l’aumento della popolazione mondiale richiede un incremento della produzione alimentare e quindi agricola, d’altro canto l’agricoltura è considerata una delle attività antropiche con il più grande impatto ambientale. Come è noto, la rivoluzione agricola ha portato ad un aumento …
