The unprecedented ongoing biodiversity decline necessitates scalable means of monitoring in order to fully understand the underlying causes. DNA metabarcoding has potential provide a powerful tool for accurate and rapid monitoring. Unfortunately, many cases, lack universal standards undermines widespread application metabarcoding. One most important considerations plants, aside from selecting p...

From a rRNA repeating unit (9.1 kbp) of mustard we have The DNA was sequenced according to the method of Maxam sequenced the first internal transcribed spacer, the 5.8S rRNA and Gilbert gene, and the second internal transcribed spacer [1]. Here, we present the nucleotide sequence of a 5500 bp fragment containing the 3 ' end terminus of the 25S gene (486 bp), the intergenic spacer REFERENCES (32...

The aim of the present study was to analyse sequences of 16S-23S internal transcribed spacer regions of different Geobacillus species, identify structural elements of these regions and evaluate the possibility to use these structural elements in the taxonomy of the genus Geobacillus. GEOBAC-PCR was used in order to obtain 16S-23S rRNA internal transcribed spacer sequences. Certain structural el...

three species of the genus xylaria (xylariaceae) are presented based on collections from guilan province, iran. both morphological and molecular characteristics were used in order to identify these species. xylaria longissima sp. nov. is described and illustrated as a new xylaria species and x. cf. striata and x. xylarioides are reported as new records from iranian mycobiota. xylaria longissima...

This study represents phylogenetic analyses of two woody polygonaceous genera Calligonum and Pteropyrum using both chloroplast fragment (trnL-F) and the nuclear ribosomal internal transcribed spacer (nrDNA ITS) sequence data. All inferred phylogenies using parsimony and Bayesian methods showed that Calligonum and Pteropyrum are both monophyletic and closely related taxa. They have no affinity w...
