DOI: 10.1021/acs.analchem.9b04687

Abstract: It remains a technical challenge to accurately identify close species of herbal medicines, especially from adulterants, because of their highly identical phenotypes and chemical compositions. Here, we report a direct, sequencing-free, high-curvature nanostructuring-based electrochemical herb… read more here.

DOI: 10.1371/journal.pone.0253173

Abstract: Second Internal Transcribed Spacer (ITS2) ribosomal DNA (rDNA) sequence is a widely used molecular marker for species-identification or -delimitation due to observed concerted evolution which is believed to homogenize rDNA copies in an interbreeding population.… read more here.

DOI: 10.1371/journal.pone.0283847

Abstract: This is the first study to systematically evaluate rRNA secondary structures of Hedysareae with an emphasis on Hedysarum. ITS2 and 5.8S regions of the genus shared a common secondary structure with a four-fingered central loop,… read more here.

DOI: 10.3390/ijms24097716

Abstract: Guanine and cytosine (GC) content is a fundamental component of genetic diversity and essential for phylogenetic analyses. However, the GC content of the ribosomal internal transcribed spacer 2 (ITS2) remains unknown, despite the fact that… read more here.

DOI: 10.3390/insects15100748

Abstract: Simple Summary The South American fruit fly Anastrepha fraterculus (Wiedmann) is found from northern Mexico to northern Argentina, where it causes damage to many different wild and cultivated fruits. It is a not a single… read more here.
