The earliest angiosperms: evidence from mitochondrial, plastid and nuclear genomes
Angiosperms have dominated the Earth's vegetation since the mid-Cretaceous (90 million years ago), providing much of our food, fibre, medicine and timber, yet their origin and early evolution have… Expand
Phylogeny and biogeography of Panax L. (the ginseng genus, araliaceae): inferences from ITS sequences of nuclear ribosomal DNA.
Panax, the ginseng genus, is one of the most medicinally important genera in the Orient and demonstrates a classical eastern Asian and eastern North American disjunct distributional pattern.… Expand
Molecular evolution and phylogenetic implications of internal transcribed spacer sequences of Ribosomal DNA in Winteraceae
- Youngbae Suh, L. B. Thien, Helena E. Reeve, E. Zimmer
- Biology
- 1 September 1993
The internal transcribed spacers and the 5.8S coding region of nuclear ribosomal DNA were sequenced and analyzed to address questions of generic relationships in Winteraceae. The molecular data… Expand
Unraveling the evolutionary radiation of the families of the Zingiberales using morphological and molecular evidence.
The Zingiberales are a tropical group of monocotyledons that includes bananas, gingers, and their relatives. The phylogenetic relationships among the eight families currently recognized are… Expand
Phylogeny of Basal Angiosperms: Analyses of Five Genes from Three Genomes1
DNA sequences of five mitochondrial, plastid, and nuclear genes from 105 species (103 genera and 63 families) representing all major lineages of gymnosperms and basal angiosperms were analyzed using… Expand
On the evolutionary origins of the cacti
- M. Hershkovitz, E. Zimmer
- Biology
- 1 May 1997
Understanding evolutionary responses of plants to desert environments depends upon phylogenetic knowledge of desert plants. The diverse American desert family Cactaceae has been presumed, on the… Expand
