Ricardo I. Alcalá Briseño
I am a Ph.D. candidate at the Plant Pathology Department at the University of Florida. I am investigating viral communities assemblage in landscape agroecology (Virome Network Analysis ViNA). Also, I am interested in the identification of ecological patterns of viruses.
The goal of my research is to asses the viral ecological dynamics in crop systems.

Research
Virome Network Analysis
I am developing a network framework for the analysis of complex viromes in the agroecological landscape, by applying concepts of island biogeography, network analysis and metagenomics. The bipartite network structure explains very intuitively the association of virus and plant–hosts, describing ecological patterns of interactions such as nested and modular. Understanding community structure of viruses, we can translate that knowledge into management strategies and apply other plant disease ecology. A long-term goal of this work is to create a more quantitative approach for understanding community assembly rules and for predicting future emerging pathogens.
Virome dynamics respond to the distribution of plants, changes in the landscape for agricultural usage and climate change alter the patterns of distribution of hosts, and vectors, therefore the landscape connectivity allow emerging pathogens to establish in new niches. We are comparing host and location combinations to determine ecological patterns, viral positive and negative interactions, and spatial relationships.
Diversity of viruses: Viral discovery
Viral metagenomics is a useful tool for assessing the diversity of viruses. Using high-throughput sequencing (HTS) has become the standard tool for virus diagnosis, and the to go tool for revealing associations of viruses within the plant host. Viruses interactions occur at different levels within plant-host, causing necrosis, mosaics, stunting symptoms and some times, asymptomatic. Another interesting feature is that this technique reveals multiple interactions that otherwise would have been difficult to identify, in most cases when an unknown virus is present within the same plant.
