Interspecific hybrids and allopolyploids often silence expression of ribosomal genes inherited from one parental species. This phenomenon, known as nucleolar dominance, was studied at the population level in recent (
O 34 Molecular studies of Amaranthaceae based on matK DNA sequence data Oluwatoyin T. Ogundipe 1 and Mark Chase 2 1 Department of Botany and Microbiology, University of Lagos, Akoka, Lagos, Nigeria; toyin60@yahoo.com 2 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3DS, Comparative sequencing of the chloroplast matK coding and non-coding regions was used to examine relationship among the species of Amaranthaceae with emphasis on the West African species and other closely related families such as Chenopodiaceae, Portulacaceae and Caryophyllaceae. Phylogenetic analysis of the matK sequences alone and in combination using maximum parsimony methods produced monophyletic lineage of Amaranthaceae-Chenopodiaceae. Our results indicated that a polyphyletic Celosieae as sister to an Amaranthus-Chemissoa lineage. Subfamily Amaranthoideae is paraphyletic to the core Gomphrenoids. This study also shows that the polyphyly of Amarantheae is apparent and so is the polyphyly of Amaranthinae. 35
