AI Article Synopsis
- Grouper species like E. epistictus, E. heniochus, E. latifasciatus, E. magniscuttis, and E. radiatus share similar color patterns, complicating their identification in the field.
- DNA barcoding was used to clarify taxonomic relationships among these species, with genetic distances ranging from 0.079 to 0.164.
- The study confirmed distinct clades in a phylogenetic tree that align with earlier studies in Indian waters, and generated barcode sequences for E. heniochus and E. magniscuttis that are new to GenBank.
Article Abstract
Grouper species of Epinephelus - E. epistictus, E. heniochus, E. latifasciatus, E. magniscuttis and E. radiatus exhibit overlapping colour pattern that often leads to misidentification in the field. Even the colour pattern of juveniles of these species in different size groups varies considerably with that of adults. DNA barcoding of these five species was carried out to reinforce our knowledge on existing taxonomic relationships derived based on morphological and biochemical genetic studies that were previously done from Indian waters. Mean interspecific genetic distance is in the range 0.079-0.164.The phylogeny tree revealed distinct clades for species that are in concurrence with previous taxonomic and allozyme electrophoretic studies carried out from central eastern coast of India. Barcode sequences generated for the first time for species E. heniochus from Indian waters for E. magniscuttis so far there are no reference sequences in GenBank.

The chloroplast genome is an important tool for studying plant classification, evolution, and the heterologous production of secondary metabolites and protein drugs. With advancements in sequencing technology and reductions in sequencing costs, chloroplast genome data have rapidly accumulated. However, existing chloroplast genome databases suffer from issues such as incomplete data, inadequate management, and inconsistent, inaccurate information, posing significant challenges for the development and utilization of the chloroplast genome.

Alfalfa is one of the most economically valuable forage crops in the world. However, molecular cytogenetic studies in alfalfa lag far behind other cash crops and have reached a bottleneck. Here, we developed a novel chromosome identification system by designing 21 oligo probes in specific regions of each chromosome, which can be used as a barcode to simultaneously distinguish all chromosomes in a cell.
