High-throughput sequencing-based assembly of chloroplast genomes of five pine tree species

Mitochondrial DNA. Part B. Resources, 2020
Pinus plants are the largest existing group of gymnosperms and one of the most highly differentiated taxa. Due to its huge ecological, economic, and scientific value, the genetic diversity and the relationship between the intraspecific evolution of Pinus

Tree contractions and evolutionary trees [PDF]

SIAM Journal on Computing, 1997
An evolutionary tree is a rooted tree where each internal vertex has at least two children and where the leaves are labeled with distinct symbols representing species. Evolutionary trees are useful for modeling the evolutionary history of species. An agreement subtree of two evolutionary trees is an evolutionary tree which is also a topological subtree

ASTRAL-III: polynomial time species tree reconstruction from partially resolved gene trees

BMC Bioinformatics, 2018
Evolutionary histories can be discordant across the genome, and such discordances need to be considered in reconstructing the species phylogeny. ASTRAL is one of the leading methods for inferring species trees from gene trees while accounting for gene ...

Blue, white, and red ocean planets - Simulations of orbital variations in flux and polarization colors

, 2019
An exoplanet's habitability will depend strongly on the presence of liquid water. Flux and/or polarization measurements of starlight that is reflected by exoplanets could help to identify exo-oceans.

Prevalence and correlates of antibodies to Neospora caninum in dogs in Portugal [PDF]

, 2014
Neosporosis, caused by Neospora caninum, is an important cause of abortion in cattle and of neurological disease in dogs. This study investigated the prevalence and correlates of antibodies to N.

Transcriptomic and metabolomic profiling provide novel insights into fruit development and flesh coloration in Prunus mira Koehne, a special wild peach species

BMC Plant Biology, 2019
Background Flesh color is one of the most important traits for the commercial value of peach fruit. To unravel the underlying regulatory network in Prunus mira, we performed an integrated analysis of the transcriptome and metabolome of 3 fruit types with

Sussing merger trees: the Merger Trees Comparison Project [PDF]

, 2013
Merger trees follow the growth and merger of dark-matter haloes over cosmic history. As well as giving important insights into the growth of cosmic structure in their own right, they provide an essential backbone to semi-analytic models of galaxy ...

Random real trees [PDF]

, 2006
We survey recent developments about random real trees, whose prototype is the Continuum Random Tree (CRT) introduced by Aldous in 1991. We briefly explain the formalism of real trees, which yields a neat presentation of the theory and in particular of ...
