Ribosomal DNA (rDNA) sequences have been aligned and compared in a number of living
organisms, and this approach has provided a wealth of information about phylogenetic …

Abrupt speciation through interspecific hybridisation is an important mechanism in
angiosperm evolution. Flowering plants therefore offer excellent opportunities for studying …

Spacer-length (sl) variation in ribosomal RNA gene clusters (rDNA) was surveyed in 502
individual barley plants, including samples from 50 accessions of cultivated barley, 25 …

The phylogenetic relationships of the genus Sorghum and related genera were studied by
sequencing the nuclear ribosomal DNA (rDNA) internal transcribed spacer region (ITS) …

A major obstacle facing many taxonomists interested in analyzing variation at the DNA level
is the preservation of their plant material, since plants are often collected far from laboratory …

The 3′ region of the external transcribed spacer (ETS) of 18S–26S nuclear ribosomal DNA
was sequenced in 19 representatives ofCalycadenia/Osmadeniaand two outgroup species …

This 2013 edition of the Catalogue of Gene Symbols for Wheat represents 45 years of
curation of wheat genetic information which began with my appointment as Curator at the …

Polymorphism in the lengths of restriction fragments at 53 single-copy loci, the rRNA locus
Nor3, and the high-molecular-weight glutenin locus Glu1 was investigated in the D genome …

Ribosomal RNA genes in plants are highly variable both in copy number and in intergenic
spacer (IGS) length. This variability exists not only between distantly related species, but …

A diverse array of molecular approaches is now available to the plant systematist for use in
phylogenetic inference, including restriction site analysis, comparative sequencing, analysis …
