A polynomial time algorithm for calculating the probability of a ranked gene tree given a species tree [PDF]

, 2012
In this paper, we provide a polynomial time algorithm to calculate the probability of a {\it ranked} gene tree topology for a given species tree, where a ranked tree topology is a tree topology with the internal vertices being ordered. The probability of

The role played by exotic plants in urban ecosystems: comments on Spennemann, 2019 [PDF]

, 2020
The article written by Dirk HR Spennemann, and published in the European Journal of Ecology, addresses the role played by a palm tree species native to the Canary Islands as food source for several frugivore species found in Australian cities.

Comparison of growth development of micropropagated and generatively reproduced wild cherry (Prunus avium (L.) L.) on the Polná demonstration plot (Czech Republic) up to the age of 15 years

Journal of Forest Science, 2016
Four clonal progenies of wild cherry obtained using an in vitro technique and control progeny of generative origin were tested on the Polná research plot in southeastern Bohemia. Growth characteristics of cherry trees were determined each year during the

Third-generation sequencing and metabolome analysis reveal candidate genes and metabolites with altered levels in albino jackfruit seedlings

BMC Genomics, 2021
Background Most plants rely on photosynthesis; therefore, albinism in plants with leaves that are white instead of green causes slow growth, dwarfing, and even death.

Third-generation sequencing found LncRNA associated with heat shock protein response to heat stress in Populus qiongdaoensis seedlings

BMC Genomics, 2020
Background As air temperatures increase globally, more and more plants are exposed to heat-stress conditions. Although many studies have explored regulation networks in plants with the aim of improving their heat-stress tolerance, only few have revealed ...

Gene Trees in Species Trees [PDF]

Systematic Biology, 1997
Exploration of the relationship between gene trees and their containing species trees leads to consideration of how to reconstruct species trees from gene trees and of the concept of phylogeny as a cloud of gene histories. When gene copies are sampled from various species, the gene tree relating these copies might disagree with the species phylogeny ...

Phenotypic and molecular marker analysis uncovers the genetic diversity of the grass Stenotaphrum secundatum

BMC Genetics, 2020
Background Stenotaphrum secundatum is an important grass with a rich variety of accessions and great potential for development as an economically valuable crop. However, little is known about the genetic diversity of S.
