Hilu Systematics of Water Lilies ( Genus Nymphaea L . ) Using 18 S rDNA Sequences

  author={Maliwan Nakkuntod and S. Srinarang and W. F. K.},
Water lily (Nymphaea L.) is the largest genus of Nymphaeaceae. This family is composed of six genera (Nuphar, Ondinea, Euryale, Victoria, Barclaya, Nymphaea). Its members are nearly worldwide in tropical and temperate regions. The classification of some species in Nymphaea is ambiguous due to high variation in leaf and flower parts such as leaf margin, stamen appendage. Therefore, the phylogenetic relationships based on 18S rDNA were constructed to delimit this genus. DNAs of 52 specimens…

Phylogeny, Classification and Floral Evolution of Water Lilies (Nymphaeaceae; Nymphaeales): A Synthesis of Non-molecular, rbcL, matK, and 18S rDNA Data

A well-corroborated phylogeny of water lily genera is presented that is based on agreement between non-molecular data and DNA sequences obtained from both organellar and nuclear genomes and is used to encourage the adoption of an evolutionarily based classifi- cation system for water lilies.

Towards a complete species tree of Nymphaea: shedding further light on subg. Brachyceras and its relationships to the Australian water-lilies

A middle Miocene origin is inferred for the New World Brachyceras lineage that must have dispersed out of Africa either via a Beringian migrational route or through immediate long distance dispersal.

Phylogeny of Nymphaea (Nymphaeaceae): Evidence from Substitutions and Microstructural Changes in the Chloroplast trnT‐trnF Region

Phylogenetic relationships among 35 of an estimated 45–50 species of Nymphaea are presented based on an analysis of the chloroplast trnT‐trnF region, showing a strong insertion bias in simple sequence repeats and AT‐rich, satellite‐like sequence parts that seem to be conserved in sequence within species but are highly variable among species.

A conclusion obtained from the present analysis was that the following three families should be recognized in the Nymphaeales; Nelumbonaceae NymphAEaceae, and Ceratophyllaceae.

Comparative morphology and floral biology of three species of the genus of Nymphaea from Bangladesh

Morphology and floral biology of three species of the genus Nymphaea (Nymphaeaceae) of Bangladesh revealed that N. nouchali, N. pubescens and N. rubra , were normal, protogynous or normal and

Cytogenetics of aquatic ornamentals. VI. Evolutionary trends and relationships in the genus Nymphaea.:VI. Evolutionary trends and relationships in the genus Nymphaea

Polyploidy, weak development of isolating mechanism, structural changes of chromosomes and gene mutations appear to have involved for the evolution in this genus Nymphaea.

The phylogenetic position of taxaceae based on 18S rRNA sequences

The phylogenetic analysis of the new sequence data with the published 18S rRNA sequence of Zamia pumila (a cycad) as an outgroup strongly indicates that Taxus, Pinus, and Podocarpus form a monophyletic group with the exclusion of Ginkgo and thattaxus is more closely related to Pinus than to Podoc Carpus and should be classified as a family of Coniferales.

Developmental morphology of ovules and seeds of Nymphaeales.

The oldest (early Cretaceous) probable nymphaealean seeds had the micropyle-hilum complex, suggesting that the hood-shaped outer integument may be primitive in the Nymphaeales.

Nuclear and plastid DNA sequences reveal complex reticulate patterns in Australian water-lilies (Nymphaea subgenus Anecphya, Nymphaeaceae)

A phylogenetic signal obtained from the chloroplast and the nuclear genomes point to recent hybridisation or introgression in this group of Australianwater- lilies, and molecular data potentially hint to a case of still imperfect taxonomy.
