Limit groups and groups acting freely on R^n-trees [PDF]

Geometry & Topology, 2004
We give a simple proof of the finite presentation of Sela's limit groups by using free actions on R^n-trees. We first prove that Sela's limit groups do have a free action on an R^n-tree.

The Automorphism Tower of Groups acting on Rooted Trees [PDF]

Transactions of the American Mathematical Society, 2006
The group of isometries W of a regular rooted tree, and many of its subgroups with branching structure, have groups of automorphisms induced by conjugation in W.

Genome-Wide Identification and Evolutionary Analysis of m6A-Related Gene Family in Poplar Nanlin895 [PDF]

Plants
Background: N6-methyladenosine (m6A) is the most prevalent chemical modification of eukaryotic RNA, playing a crucial role in regulating plant growth and development, stress responses, and other essential biological processes. The enzymes involved in m6A

Ramification structures for quotients of multi-EGS groups [PDF]

International Journal of Group Theory, 2023
Groups associated to surfaces isogenous to a higher product of curves can be characterised by a purely group-theoretic condition, which is the existence of a so-called ramification structure.

Genome-wide identification and characterization of NHL gene family in response to alkaline stress, ABA and MEJA treatments in wild soybean (Glycine soja) [PDF]

PeerJ, 2022
Background NDR1/HIN1-like (NHL) family genes are known to be involved in pathogen induced plant responses to biotic stress. Even though the NHL family genes have been identified and characterized in plant defense responses in some plants, the roles of ...

Viviparity and habitat restrictions may influence the evolution of male reproductive genes in tsetse fly (Glossina) species

BMC Biology, 2021
Background Glossina species (tsetse flies), the sole vectors of African trypanosomes, maintained along their long evolutionary history a unique reproductive strategy, adenotrophic viviparity.

A Comparative Analysis of Ash Leaf-Colonizing Bacterial Communities Identifies Putative Antagonists of Hymenoscyphus fraxineus

Frontiers in Microbiology, 2020
In the last few years, the alarming spread of Hymenoscyphus fraxineus, the causal agent of ash dieback, has resulted in a substantial threat to native ash stands in central and northern Europe.
