The evolutionary conservation and versatility of a new set of nuclear primers for the amplification of the ribosomal internal transcribed spacer regions in insects and other invertebrates have been studied. These primers, conserved across Insecta and other invertebrates, are based on a comprehensive taxonomic survey of the current DNA sequence databases. Their versatility was demonstrated by ex...

The rare and endangered plants of any country are important genetic resources that often require urgent conservation measures. Assessment of phylogenetic relationships and evaluation of genetic diversity is very important prior to implementation of conservation strategies for saving rare and endangered plant species. We used internal transcribed spacer sequences of nuclear ribosomal DNA for the...

Serofluid dish (or Jiangshui, in Chinese), a traditional food in the Chinese culture for thousands of years, is made from vegetables by fermentation. In this work, microorganism community of the fermented serofluid dish was investigated by the culture-independent method. The metagenomic data in this article contains the sequences of fungal internal transcribed spacer (ITS) regions of rRNA genes...

In June 2020, many plants exhibited symptoms of root rot and foliar blight in the experimental field common sage Şanlıurfa province, Turkey. The pathogen was identified as Neoscytalidium novaehollandiae based on morphological characteristics phylogenetic analysis partial sequence transcription elongation factor 1-α gene internal transcribed spacer rDNA. Koch’s postulates were fulfilled by succe...

Seven fungal isolates were identified as pan-global Hypocrea/Trichoderma species, from section Trichoderma, on the basis of their morphology. These species were H. lixii/T. harzianum and H. orientalis/T. longibrachiatum. PCR-based markers with primer M13 (core sequence of phage M13) and internal-transcribed spacer sequences of ribosomal DNA were used to confirm the identity of the two Trichoder...

Tetranychid mites are serious agricultural pests. Identification of species in the Tetranychidae is hampered by their close morphological similarities, especially for species within the genus Tetranychus. In this study, we examined the relationships of nine agriculturally important species in the Tetranychidae from China based on mitochondrial (cytochrome c oxidase subunit 1) and nuclear (inter...

Sequences of the complete nuclear ribosomal DNA (rDNA) gene from five individual Paramphistomum cervi were determined for the first time. The five complete rDNA sequences, which included the 18S rDNA, the internal transcribed spacer 1 (ITS1), the 5.8S rDNA, the internal transcribed spacer 2 (ITS2), the 28S rDNA, and the intergenic spacer (IGS) regions, had a length range of 8,493-10,221 bp. The...
