The Promise of Molecular and Genomic Techniques for Biodiversity Research and DNA Barcoding of the Arabian Peninsula Flora

Frontiers in Plant Science, Journal Year: 2019, Volume and Issue: 9

Published: Jan. 21, 2019

The Arabian Peninsula is known to have a comprehensive and rich endowment of unique genetically diverse plant genetic resources. Analysis conservation biological diversity crucial issue the whole Peninsula. rapid accurate delimitation identification species analysis first critical step in assessment distribution, population abundance threats related particular target species. During last two decades, classical strategies evaluating variability such as morphology physiology been greatly complemented by phylogenetic, taxonomic, breeding research molecular studies. At present, initiatives are taking place around world generate DNA barcode libraries for vascular flora make these data available order better understand, conserve utilize biodiversity. number herbarium collection-based evolutionary genetics genomics studies being conducted has increasing worldwide. herbaria provide resource already preserved identified material well freshly collected samples from wild can be used creating reference library region. This review discusses main genomic techniques biodiversity analysis. Hence, we highlight emphasizing various undertaken during ten years study Special emphasis on role barcoding powerful tool provided, along with library.

Authentication of berries and berry‐based food products

Comprehensive Reviews in Food Science and Food Safety, Journal Year: 2021, Volume and Issue: 20(5), P. 5197 - 5225

Published: Aug. 1, 2021

Abstract Berries represent one of the most important and high‐valued group modern‐day health‐beneficial “superfoods” whose dietary consumption has been recognized to be beneficial for human health a long time. In addition being delicious, berries are rich in nutrients, vitamins, several bioactive compounds, including carotenoids, flavonoids, phenolic acids, hydrolysable tannins. However, due their high value, berry‐based products often subject fraudulent adulteration, commonly economical gain, but also unintentionally misidentification species. Deliberate adulteration comprises substitution high‐value with lower value counterparts mislabeling product contents. As is deceptive toward customers presents risk public health, food authentication through different methods applied as countermeasure. Although many have developed terms fast, sensitive, reliable, low‐cost analysis myriad species, application on still limited. The present review provides an overview development analytical chemistry methods, such isotope ratio analysis, liquid gas chromatography, spectroscopy, well DNA‐based electronic sensors, products. We provide earlier use recent advances these discuss drawbacks related application.

DNA Barcodes for Accurate Identification of Selected Medicinal Plants (Caryophyllales): Toward Barcoding Flowering Plants of the United Arab Emirates

Diversity, Journal Year: 2022, Volume and Issue: 14(4), P. 262 - 262

Published: March 30, 2022

The need for herbal medicinal plants is steadily increasing. Hence, the accurate identification of plant material has become vital safe usage, avoiding adulteration, and trading. DNA barcoding shown to be a valuable molecular tool plants, ensuring safety efficacy materials therapeutic significance. Using morphological characters in genera with closely related species, species delimitation often difficult. Here, we evaluated capability nuclear barcode ITS2 plastid barcodes rbcL matK identify 20 medicinally important Caryophyllales. In our analysis, applied an integrative approach discrimination using pairwise distance-based unsupervised operational taxonomic unit “OTU picking” methods, viz., ABGD (Automated Barcode Gap Analysis) ASAP (Assemble Species by Automatic Partitioning). Along OTU picking Supervised Machine Learning methods (SML) were also implemented recognize divergent taxa. Our results indicated that was more successful distinguishing between examined implying it could used detect contamination adulteration these plants. Moreover, this study suggests combination than one method assist resolution morphologically similar or

Complete chloroplast genomes of Sorbus sensu stricto (Rosaceae): comparative analyses and phylogenetic relationships

BMC Plant Biology, Journal Year: 2022, Volume and Issue: 22(1)

Published: Oct. 22, 2022

Abstract Background Sorbus sensu stricto ( s.s. ) is a genus with important economical values because of its beautiful leaves, and flowers especially the colorful fruits. It belongs to tribe Maleae family Rosaceae, comprises about 90 species mainly distributed in China. There on-going dispute infrageneric classification delimitation as are morphologically similar. With aim shedding light on circumscription taxa within genus, phylogenetic analyses were performed using 29 chloroplast (cp) genomes (16 newly sequenced) representing two subgenera eight sections. Results The 16 cp sequenced range between 159,646 bp 160,178 length. All samples examined 22 re-annotated lato s.l. contain 113 unique genes 19 these duplicated inverted repeat (IR). Six hypervariable regions including trnR - atpA , petN psbM rpl32-trnL trnH psbA trnT trnL ndhC-trnV screened 44–53 SSRs 14–31 dispersed repeats identified potential molecular markers. Phylogenetic under ML/BI indicated that polyphyletic, but other five segregate genera, Aria Chamaemespilus Cormus Micromeles Torminalis monophyletic. Two major clades four sub-clades resolved full-support s.s . not consistent existing classification. subgenera, subg. Albocarmesinae supported monophyletic when S. tianschanica transferred from hupehensis var. paucijuga respectively. current at sectional level by analysis genome phylogeny. Conclusion Phylogenomic useful for inferring relationships Though structure highly conserved sequences used most promising molecule makers population genetics, studies.
