Phylogenetics of Betula (Betulaceae) inferred from sequences of nuclear ribosomal DNA
Abstract Interspecific relationships of Betula remain elusive, making it difficult to examine morphological diversification and historical biogeography of the genus. In this study, sequences of the… Expand
POLYPHYLETIC ORIGIN OF PARALLEL BASAL BODIES IN SWIMMING CELLS OF CHLOROPHYCEAN GREEN ALGAE (CHLOROPHYTA) 1
The evolutionary affinities of Heterochlamydomonas Cox and Deason and Dictyochloris Vischer ex Starr were investigated using phylogenetic analyses of a combined data set of 18S and 28S rDNA sequences… Expand
PHYLOGENETICS OF ACER (ACEROIDEAE, SAPINDACEAE) BASED ON NUCLEOTIDE SEQUENCES OF TWO CHLOROPLAST NON-CODING REGIONS
ABSTRACT Acer is one of the most diverse woody genera in the Northern Hemisphere. Recent phylogenetic studies support the placement of Acer and Dipteronia—sole members of the traditional Aceraceae—in… Expand
Phylogenetic Relationships of Diploid Species of Betula (betulaceae) Inferred from DNA Sequences of Nuclear Nitrate Reductase
Abstract A long history of hybridization and introgression in the evolution of Betula has made the use of chloroplast genes to infer interspecific relationships prone to errors. Single and low copy… Expand
A YAC contig in Xq22.3-q23, from DXS287 to DXS8088, spanning the brain-specific genes doublecortin (DCX) and PAK3.
Although several genes for mental retardation and epilepsy, including double cortex/X-linked lissencephaly (DC/XLIS), have been localized to Xq21.3-q23, there has been no complete physical map of… Expand
Molecular Confirmation of Intergeneric Hybrid ×Chitalpa tashkentensis (Bignoniaceae)
Intergeneric hybrids are generally rare; nevertheless, such putative hybrids need confirmation from other lines of evidence besides morphological intermediacy. In this study the authors used DNA… Expand
