“…In this study, we used two complementary methods (environmental DNA (eDNA) metabarcoding and gillnetting) to survey fish communities in this unique waterway. Using COI (cytochrome oxidase subunit I) metabarcoding, we detected a total of 142 fish species, including evidence for the presence of sixteen Atlantic and eight Pacific marine fish in different freshwater sections of the Canal. …”

“…Moreover, the Bray-Curtis dissimilarity matrices were positively correlated with Nei’s genetic distance of the host but were not correlated with the COI-based genetic distance. This study provides a scientific basis for further understanding the ecological adaptability of red imported fire ants during invasion and dispersal. …”

“…Thus, to evaluate the diversity and distribution of Cirripectes species in the Mascarene Archipelago, a little‐studied region but an important biodiversity hotspot, complete mitochondrial genomes, and nuclear rhodopsin genes were sequenced for 39 specimens collected with ARMS deployed on outer reef slopes at Reunion and Rodrigues islands. Mitochondrial COI sequences were analyzed to integrate these specimens within the largest dataset of publicly available sequences. …”

“…Here, we show that the relative transcript expression of CORONATINE INSENSITIVE1 (COI1) and PLANT DEFENSIN1.2 (PDF1.2) as a marker of the JA pathway is significantly higher while ISOCHORISMATE SYNTHASE1 (ICS1) and NON-EXPRESSOR OF PATHOGENESIS-RELATED GENES1 (NPR1), the markers of the SA pathway, are downregulated in the gi-100 mutants compared to Col-0 plants. …”

“…Our sequencing results indicate a genetic match with the cryptic seep species, Oligobrachia haakonmosbiensis (99% pairwise identity for 574 bp mtCOI fragments). Due to its similarity with O. webbi, the identity of O. haakonmosbiensis has been a matter of debate since its description, which we have now resolved. …”

“…Subsequently, this study corroborates the suitability of the mitochondrial cytochrome c oxidase subunit 1 (COI) marker sequence for species delimitation. In total, 55 barcodes of the Arctiavillica complex were compared, and two molecular species delimitation algorithms were applied to reveal the potential Molecular Operational Taxonomic Units (MOTUs), namely the distance-based Barcode Index Number (BIN) System, and the hierarchical clustering algorithm based on a pairwise genetic distances approach using the Assemble Species by Automatic Partitioning (ASAP). …”
