One of the most popular sequences for phylogenetic inference at the generic and
infrageneric levels in plants is the internal transcribed spacer (ITS) region of the 18S–5.8 S …

▪ Abstract Over 35 years ago, Susumu Ohno stated that gene duplication was the single
most important factor in evolution. He reiterated this point a few years later in proposing that …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which
seems to have arisen from one or more cycles of genome doubling. Polyploidy has been …

Modern techniques of gene cloning have identified the CesA genes as encoding the
probable catalytic subunits of the plant CelS, the cellulose synthase enzyme complex …

The formation of polyploids significantly increases the complexity of transcriptional
regulation, which is expected to be reflected in sophisticated higher-order chromatin …

Molecular data have had a profound impact on the field of plant systematics, and the
application of DNA-sequence data to phylogenetic problems is now routine. The majority of …

Polyploidy is produced by multiplication of a single genome (autopolyploid) or combination
of two or more divergent genomes (allopolyploid). The available data obtained from the …

To study the consequences of hybridization and genome duplication on polyploid genome
evolution and adaptation, we used independently formed hybrids (Spartina× townsendii and …

Low-copy nuclear genes in plants are a rich source of phylogenetic information. They hold a
great potential to improve the robustness of phylogenetic reconstruction at all taxonomic …
