Abstract Apusomonads are cosmopolitan bacterivorous biflagellate protists usually gliding on freshwater and marine sediment or wet soils. These nanoflagellates form a sister lineage to opisthokonts and may have retained ...

Phylogenetics plays a crucial role in enhancing our understanding of molecular sequence evolution and is regarded as one of the most effective tools for studying the origin of contagious diseases. This thesis explores the ...

Background Olive tree (Olea europaea L. subsp. europaea, Oleaceae) has been the most emblematic perennial crop for Mediterranean countries since its domestication around 6000 years ago in the Levant. Two taxonomic varieties ...

L'evolució de seqüències moleculars es pot modelitzar utilitzant un procés de Markov en un arbre filogenètic, una de les representacions més habituals de les relacions evolutives entre diferents entitats biològiques. Sota ...

Phylogenetic varieties related to equivariant substitution models have been studied largely in the last years. One of the main objectives has been finding a set of generators of the ideal of these varieties, but this has ...

An evolutionary process is frequently modeled as a sequence of the four bases A,C,G,T, each of them changing independently following a Markov process. The main goal of this project are two: first of all, we wanted to ...

Abstract Ancyromonads are small biflagellated protists with a bean-shaped morphology. They are cosmopolitan in marine, freshwater, and soil environments, where they attach to surfaces while feeding on bacteria. These poorly ...

Large-scale gene duplication, including whole-genome duplication (WGD), is a very common phenomenon in eukaryotic genomes. Bursts of gene duplications are considered a major source of evolutionary innovation and have been ...

We present the phylogenetic quartet reconstruction method SAQ (Semi-Algebraic Quartet reconstruction). SAQ is consistent with the most general Markov model of nucleotide substitution and, in particular, it allows for rate ...
