Trinets encode tree-child and level-2 phylogenetic networks [PDF]
arXiv, 2012 Phylogenetic networks generalize evolutionary trees, and are commonly used to represent evolutionary histories of species that undergo reticulate evolutionary processes such as hybridization, recombination and lateral gene transfer. Recently, there has been great interest in trying to develop methods to construct rooted phylogenetic networks from ...

Advanced Science, EarlyView.Cryo‐EM reveals a closed 17‐subunit LH ring encircling the RC‐LH1 complex in Dinoroseobacter shibae, featuring a novel helix‐turn‐helix subunit bridging RC and LH. Mg2⁺/Ca2⁺ stabilizes the complex, while periplasmic Cyt c₂ mediates electron transfer via a tri‐heme Cyt to the special pair of bacteriochlorophylls. Insights into energy/electron efficiency

Bridging the gap between rooted and unrooted phylogenetic networks [PDF]
arXiv, 2015 The need for structures capable of accommodating complex evolutionary signals such as those found in, for example, wheat has fueled research into phylogenetic networks. Such structures generalize the standard phylogenetic tree model by also allowing cycles and have been introduced in rooted and unrooted form. In contrast to phylogenetic trees, however,

Multiple Comparisons of Log-Likelihoods with Applications to Phylogenetic Inference
Molecular biology and evolution, 1999 The maximum-likelihood method for inferring mo-lecular phylogeny (Felsenstein 1981) is being widelyused. The probabilistic model for generating the molec-ular sequences is specified by the substitution processand the tree topology.

Next-generation sequencing yields the complete chloroplast genome of Abies kawakamii
Mitochondrial DNA. Part B. Resources, 2019 Abies kawakamii is endemic to the island of Taiwan and has been listed as a threatened species in the Red List. In present study, we reported the complete chloroplast genome of A. kawakamii. The chloroplast genome is 121,290 bp in size.

Advanced Science, EarlyView.This study presents a comprehensive multi‐omics framework to uncover cell‐type‐specific regulatory networks in plant drought responses. By integrating transcriptomic, proteomic, and epigenetic data from nearly 30 000 samples, key regulators such as CIPK23 and NLP7 are identified, revealing insights into conserved drought tolerance mechanisms and ...
