Interstitial Telomeric-like Repeats (ITR) in Seed Plants as Assessed by Molecular Cytogenetic Techniques: A Review.

2021

The discovery of telomeric repeats in interstitial regions of plant chromosomes (ITRs) through molecular cytogenetic techniques was achieved several decades ago. However, the information is scattered and has not been critically evaluated from an evolutionary perspective. Based on the analysis of currently available data, it is shown that ITRs are widespread in major evolutionary lineages sampled. However, their presence has been detected in only 45.6% of the analysed families, 26.7% of the sampled genera, and in 23.8% of the studied species. The number of ITR sites greatly varies among congeneric species and higher taxonomic units, and range from one to 72 signals. ITR signals mostly occurs…

Le arti performative nel mondo di Internet e dell’Interaction Design: l’avventura tecno-artistica di Kònic Thtr di Barcellona

2017

Che cos’è internet? Cosa rappresenta e come cambia quando s’intreccia alle arti performative, da sempre legate a uno spazio di condivisione fisico e reale? Come si libera dal suo livello strettamente tecnologico - permettere la comunicazione tra individui a distanza - per divenire tecnica mediata, medium, linguaggio metaforico? Attraverso l’analisi di alcune performance del gruppo di Barcellona Kònic Thtr si cercherà di tracciare quale sia oggi la relazione e in particolare il grado d’ibridazione tra internet e le arti performative. What is the internet? What does it represent and how does it change when it intertwines with the performing arts, which have always been linked to a physical an…

Dissimilar molecular and morphological patterns in an introgressed peripheral population of a sand dune species ( Armeria pungens , Plumbaginaceae)

2019

Introgression is a poorly understood evolutionary outcome of hybridisation because it may remain largely undetected whenever it involves the transfer of small parts of the genome from one species to another. Aiming to understand the early stages of this process, a putative case from the southernmost border of the Armeria pungens range from its congener A. macrophylla is revisited following the discovery of a subpopulation that does not show phenotypic signs of introgression and resembles typical A. pungens. We analysed morphometrics, nuclear ribosomal DNA ITS and plastid DNA (trnL‐trnF) sequences, genome size, 45S and 5S rDNA loci‐FISH data and nrDNA IGS sequences. Within the study site, mo…

DNA sequence baits targeting ultra-conserved elements in marine invertebrates

2022

This dataset includes four files of DNA sequence baits targeted to ultra-conserved elements (UCEs) identified from four different taxonomic groups of marine invertebrates: Annelida, Bivalvia, Gastropoda and Crustacea. UCE loci are genomic regions of high conservation that can be found throughout the genomes that can be extracted from the genome and sequenced for use in phylogenetic, phylogeographic and population genetic analyses. The UCE loci were located by aligning a minimum of five species’ genomes to a base genome in each taxonomic group and searching for overlapping highly conserved areas. The UCE baits were designed with screening coverage of 4X using the pipeline phyluce v. 1.6.6 (h…
