Detailed biogeographical mapping as a useful novel tool for the conservation of endemic taxa: a case of study for Iberian orchids

Open Research Europe, Journal Year: 2025, Volume and Issue: 4, P. 210 - 210

Published: Jan. 30, 2025

Background Many Iberian orchids occur in plant communities designated as habitats of interest the European Union, particularly Mediterranean grasslands and forests. Their ecological importance highlights need for a deeper understanding their distribution requirements order to develop effective conservation management policies. Methods This study focuses on biogeographical mapping characterisation five Balearic endemic orchid species at district level. Distribution data were collected from existing biodiversity databases integrated into Geographic Information System (GIS). In assign correct epithet each taxon, set rules criteria was developed ensure an objective, simple universal classification based species' areas. Results For species, identified its phytosociological assignment, bioclimatic range current status. Detailed maps produced, providing insights biogeographical, attributes these taxa. Conclusions The presented this provide basis decision-making regarding species. addition, results can be used update status better reflect needs threats.

Centenary Progress on Orchidaceae Research: A Bibliometric Analysis

Genes, Journal Year: 2025, Volume and Issue: 16(3), P. 336 - 336

Published: March 13, 2025

Background: Research on orchids has experienced substantial growth since the early 20th century, reflecting their ecological and evolutionary significance. Methods: This paper provides a comprehensive bibliometric analysis of orchid-related literature published between 1902 2024, based data retrieved from Web Science Core Collection™ (WoS). Results: The primary goal is to assess global research landscape by identifying key authors, institutions, journals, as well major themes in field. A thorough publication trends, citation frequencies, keyword co-occurrence networks was conducted uncover significant hotspots. findings indicate that orchid evolved foundational topics such taxonomy classification more intricate subjects, including conservation strategies, orchid-pollinator dynamics, role ecosystem functions. Additionally, biotechnology-related emerging dominant trend. study also highlights China highest output, while collaboration United States Europe continues grow. co-word keywords suggests future likely continue focus conservation, impacts climate change, pollination biology, symbiotic relationships with mycorrhizal fungi. Conclusions: review offers valuable insights for researchers conservationists, helping identify priorities strategies preservation sustainable use orchids.

Phylotranscriptomics reveals the phylogeny of Asparagales and the evolution of allium flavor biosynthesis

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Nov. 8, 2024

Asparagales, the largest monocot order, is renowned for its ecological, economic, and medicinal significance. Here, we leverage transcriptome data from 455 Asparagales species to explore phylogeny of Asparagales. Moreover, investigate evolutionary patterns genes involved in allium flavor formation. We not only establish a robust bifurcating but also their reticulate relationships. Notably, find that eight biosynthesis compounds underwent expansion Allium species. Furthermore, observe Allium-specific mutations one amino acid within alliinase three lachrymatory factor synthase. Overall, our findings highlight role gene expansion, increased expression, driving evolution compounds. These insights deepen understanding illuminate genetic mechanisms underpinning specialized

Comprehensive characterization and phylogenetic analysis of the complete plastomes of two ant–orchids, Caularthron bicornutum and Myrmecophila thomsoniana

BMC Plant Biology, Journal Year: 2024, Volume and Issue: 24(1)

Published: Nov. 29, 2024

Myrmecophytes, characterized by specialized structures like hollow stems that facilitate mutualistic relationships with ants, serve as an important system for studying ant-plant interactions and the adaptation mechanisms. Caularthron Myrmecophila are exemplary myrmecophytes within Orchidaceae. Previous studies suggested a genetic relationship between these two genera, placing them Laeliinae (Epidendreae), yet precise phylogenetic positioning remained uncertain. The absence of available plastome resources has hindered investigations into evolution phylogeny. In this study, we sequenced assembled complete plastomes bicornutum thomsoniana to elucidate their characteristics relationships. determined sizes were 150,557 bp C. 156,905 M. thomsoniana, GC contents 37.3% 37.1%, respectively. Notably, exhibited distinctive IR expansion SSC contraction, region measuring only 4532 containing five genes (ccsA, ndhD, rpl32, psaC, trnL-UAG), unique feature observed first time in Epidendreae. Comparative analyses species from related genus Epidendrum revealed conserved genome size, content, gene order. A total 32 33 long sequence repeats, 50 40 tandem 99 109 SSRs identified RSCU analysis demonstrated consistent pattern both plastomes, 29 out 30 codons values greater than 1 featuring A/U at third codon position. Leucine was most prevalent amino acid, while Cysteine least common. Four potential DNA barcoding regions Pi exceeding 0.07, namely ycf1, ccsA–psaC, petN–psbM, accD–psaI, subsequent reconstructions Laeliinae. Phylogenetic underscored close among Caularthron, Epidendrum, Myrmecophila. This study represents comprehensive thomsoniana. Through our characterization analyses, unveiled expansion/SSC contraction further elucidated positions. Our research contributes significant data insights dynamic ant–orchid phylogeny
