2b or not 2b: experimental evolution of functional exogenous sequences in a plant RNA virus

Willemsen, Anouk; Zwart, Mark Peter; Ambros Palaguerri, Silvia; Carrasco Jiménez, José Luis; Elena Fito, Santiago Fco (Oxford University Press, 2017)

[EN] Horizontal gene transfer (HGT) is pervasive in viruses and thought to be a key mechanism in their evolution. On the other hand, strong selective constraints against increasing genome size are an impediment for HGT, ...
A fungal transcription factor gene is expressed in plants from its own promoter and improves drought tolerance

Martínez Macías, Félix; Arif, Anjuman; González Nebauer, Sergio; Bueso Ródenas, Eduardo; Ali, Rashid; Montesinos De Lago, Consuelo; Brunaud, Veronique; Muñoz Bertomeu, Jesús; Serrano Salom, Ramón (Springer Verlag (Germany), 2015)

[EN] A fungal gene encoding a transcription factor is expressed from its own promoter in Arabidopsis phloem and improves drought tolerance by reducing transpiration and increasing osmotic potential. Horizontal gene ...
Evolutionary diversification and characterization of the eubacterial gene family encoding DXR type II, an alternative isoprenoid biosynthetic enzyme

Carretero Paulet, Lorenzo; Lipska, Agnieszka; Perez-Gil, J.; Sangari, J.; Albert, VA; Rodriguez-Concepción, M (BioMed Central, 2013-09-03)

[EN] Background: Isoprenoids constitute a vast family of natural compounds performing diverse and essential functions in all domains of life. In most eubacteria, isoprenoids are synthesized through the methylerythritol ...
Experimental evolution of pseudogenization and gene loss in a plant RNA virus

Zwart, Mark Peter; Willemsen, Anouk; Daros Arnau, Jose Antonio; Elena Fito, Santiago Fco (Oxford University Press (OUP): Molecular Biology and Evolution, 2014-01)

[EN] Viruses have evolved highly streamlined genomes and a variety of mechanisms to compress them, suggesting that genome size is under strong selection. Horizontal gene transfer has, on the other hand, played an important ...
Molecular evidence for ongoing complementarity and horizontal gene transfer in endosymbiotic systems of mealybugs

Lopez-Madrigal, Sergio; Beltrà Ivars, Aleixandre; Resurreccion, Serena; Soto Sánchez, Antonia Isabel; Latorre, Amparo; Moya, Andres; Gil, Rosario (Frontiers Media, 2014-08-26)

[EN] Intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. This is also the role of the two mealybug ...
