1. INTRODUCTION T repeated sequence complements of complex genomes can change con- siderably during species divergence. Easily detectable differences are often found between the repeated sequences in related species (Chool, 1971; Goldberg et al., 1972; Rice, 1972; Straus, 1972; Rice and Esposito...
Attempts have already been made to identify suitable genes and we evaluate these on the basis of universality and practicality, and ability to discriminate between species in the very few 'model' systems offering likely examples of sister-species-pairs. No candidate marker is ideal but LSU rDNA ...

The choice of universal primers and the characteristics of the species mixture determine when DNA metabarcoding can be quantitative[J]. Molecular Ecology, 2019, 28(2):407-419. [64]Parducci L, Väliranta M, Salonen JS, et al. Proxy comparison in ancient peat sediments :pollen, macrofossil ...
(SNP) genotyping approach based onmatK DNA barcodes to distinguish between traded timber products of Ramin (Gonystylus) species, which are all CITES protected. Unfortunately,matK can be difficult to amplify, particularly in non-angiosperms, because of the lack of sufficiently universal primers [92...
Light green cylinders in Sub-graphs (c) and (d) represent the user-defined repeat library, and black blocks in Sub-graph (d) indicate the sequencing reads from various samples of the same or similar species. Full size image Databases that support automated repeat classification and masking An...
Comparison of the evolution of ribulose-1, 5-biphosphate carboxylase (rbcL) andatpB-rbcLnoncoding spacer sequences in a recent plant group, the tribe Rubieae (Rubiaceae) Patterns of substitution in chloroplast encoded trnL-F regions were compared between species of Actaea (Ranunculales), Digitalis...
2a). There was no significant difference in the number of observed species between manual and automated methods (p = 0.2723) (Supplementary Fig. S4a), whereas, in contrast, the methods with bead beating showed a significantly higher number of observed species than those without bead beating (p...
Unlike soil samples, no difference between MP and PW was observed for water sample B in terms of bacterial alpha-diversity (Fig. 3A). Beta-ordinations, however, showed significant differences and the presence of new or rare species was found as the main driver linked to distinct separation wi...
canariensis indicated a close genetic relationship among these species. Only two of the 54 ten-mer primers ( OPM -8 and OPK -14) tested in 221 individuals from 7 localities in different islands enabled us to unambiguously identify both species. While P. canariensis possesses two exclusive ...
