Plant RNA virus fitness predictability: contribution of genetic and environmental factors

Elena Fito, Santiago Fco; Lalic, Jasna (Wiley, 2013-12)

[EN] Forecasting plant virus emergence depends on identifying the factors that determine the distribution of genetic variants within the primary host as well as across potential new hosts. It is crucial to determine: (i) ...
Plant virus evolution under strong drought conditions results in a transition from parasitism to mutualism

González, Rubén; Butkovic, Anamarija; Escaray, Francisco J.; Martínez-Latorre, Javier; Melero, Izan; Pérez-Parets, Enric; Gómez-Cadenas, Aurelio; Carrasco, Pedro; Elena, Santiago F. (Proceedings of the National Academy of Sciences, 2021-02-09)

[EN] Environmental conditions are an important factor driving pathogens' evolution. Here, we explore the effects of drought stress in plant virus evolution. We evolved turnip mosaic potyvirus in well-watered and drought ...
Predicting the Stability of Homologous Gene Duplications in a Plant RNA Virus

Willemsen, Anouk; Zwart, Mark Peter; Higueras, Pablo; Sardanyes Cayuela, Jose; Elena Fito, Santiago Fco (Oxford University Press (OUP), 2016-09)

One of the striking features of many eukaryotes is the apparent amount of redundancy in coding and non-coding elements of their genomes. Despite the possible evolutionary advantages, there are fewer examples of redundant ...
Role of host genetic diversity for susceptibility-to-infection in the evolution of virulence of a plant virus

González, Rubén; Butkovic, Anamarija; ELENA FITO, SANTIAGO FCO (Oxford University Press, 2019-07)

[EN] Predicting viral emergence is difficult due to the stochastic nature of the underlying processes and the many factors that govern pathogen evolution. Environmental factors affecting the host, the pathogen and the ...
Shrinkage of genome size in a plant RNA virus upon transfer of an essential gene into the host genome

Tromas, Nicolas; Zwart, Mark Peter; Forment Millet, José Javier; Elena Fito, Santiago Fco (Oxford University Press, 2014)

[EN] Nonretroviral integrated RNA viruses (NIRVs) are genes of nonretroviral RNA viruses found in the genomes of many eukaryotic organisms. NIRVs are thought to sometimes confer virus resistance, meaning that they could ...
Strain-dependent mutational effects for Pepino mosaic virus in a natural host

Minicka, J; Elena Fito, Santiago F.; Borodynko-Filas, N.; Rubis, B.; Hasiów-Jaroszewska, B. (Springer (Biomed Central Ltd.), 2017)

[EN] Pepino mosaic virus (PepMV) is an emerging plant pathogen that infects tomatoes worldwide. Understanding the factors that influence its evolutionary success is essential for developing new control strategies that may ...
Transcription profiling of different Arabidopsis thaliana ecotypes in response to Tobacco etch potyvirus infection

Hillung, Julia; Cuevas Torrijos, Jose Manuel; Elena Fito, Santiago Fco (Frontiers Media, 2012-06)

The use of high-throughput transcript profiling techniques has opened the possibility of identifying, in a single experiment, multiple host mRNAs whose levels of accumulation are altered in response to virus infection. ...
Tridimensional model structure and patterns of molecular evolution of Pepino mosaic virus TGBp3 protein

Hasiow-Jaroszewska, B; Czerwoniec, A; Pospieszny, H; Elena Fito, Santiago Fco (BioMed Central, 2011-06-24)

[EN] Background: Pepino mosaic virus (PepMV) is considered one of the most dangerous pathogens infecting tomatoes worldwide. The virus is highly diverse and four distinct genotypes, as well as inter-strain recombinants, ...
Ultra-deep sequencing analysis of population dynamics of virus escape mutants in RNAi-mediated resistant plants

Martinez Garcia, Fernando; Lafforgue, Guillaume; Morelli, M.; González-Candelas, F.; CHUA, N.H.; Daros Arnau, Jose Antonio; Elena Fito, Santiago Fco (Oxford University Press (OUP), 2012-11)

[EN] Plant artificial micro-RNAs (amiRs) have been engineered to target viral genomes and induce their degradation. However, the exceptional evolutionary plasticity of RNA viruses threatens the durability of the resistance ...
Viral Fitness Correlates with the Magnitude and Direction o the Perturbation Induced in the Host's Transcriptome: The Tobacco Etch Potyvirus-Tobacco Case Study

Cervera-Benet, Héctor; Ambros Palaguerri, Silvia; Bernet, Guillermo P.; Rodrigo Tarrega, Guillermo; Elena Fito, Santiago Fco (Oxford University Press, 2018-07)

[EN] Determining the fitness of viral genotypes has become a standard practice in virology as it is essential to evaluate their evolutionary potential. Darwinian fitness, defined as the advantage of a given genotype with ...
