    Plant Systematics, Second Edition, provides the basis for teaching an introduction to the morphology, evolution, and classification of land plants. It presents a foundation of the approach, methods, research goals, evidence, and terminology of plant systematics, along with the most recent knowledge of evolutionary relationships of plants and practical information vital to the field. With the advent of next-generation sequencing technologies, whole-plastome data can be obtained as a byproduct of low-coverage sequencing of the plant genomic DNA. This provides an opportunity to study plastid evolution across groups, as well as testing phylogenetic relationships among taxa.

Systematics and evolution in Salix section Longifoliae by Steven J. Brunsfeld Download PDF EPUB FB2

Background. The taxonomy and systematics of Salix subgenus Salix s.l. is difficult. The reliability and evolutionary implications of two important morphological characters (number of stamens, and morphology of bud scales) used in subgeneric classification within Salix remain untested, and a disjunct Old–New World distribution pattern of a main clade of subgenus Salix s.l., revealed by a Cited by: Phylogeny of Salix subgenus Salix s.l.

Subgenus Salix s.l. is not monophyletic, and the evolutionary history of the subgenus has involved multiple reticulation events that may mainly be due to hybridization.

The delimitation of subgenus Salix s.l. should be redefined by excluding section Triandrae and subgenus Pleuradenia from by: Conclusions: Subgenus Salix s.l.

Enzyme electrophoresis was used to examine genetic relations within a taxonomically complex group of diploid willows (Salix section Longifoliae) in North America.

Some 48 populations representing 7 morphogeographic taxa were analysed for 15 putative enzyme by: Skvortsov () was the first to suggest that section Longifoliae may be raised to subgeneric level. Section Longifoliae is distinct morphologically from all others (Schneider, ). The species of section Longifoliae produce flowers borne on leafy shoots, but have only two stamens, suggesting their affinities for both subgenera Salix and by: 5.

Journal of Systematics and Evolution (JSE) is a bi-monthly international English language journal dedicated to the understanding of biodiversity and evolution. Papers in any of the following and related fields will be considered: phylogenetics and phylogenomics, biogeography (including phylogeography), biosystematics, description of well.

This lively examination of the structure, classification, evolution, and ecology of the Orchidaceae will appeal to anyone with an eye for beauty or a bent for natural history.

It will provide professional biologists and amateur orchidists alike with a deeper understanding--and a thoroughly new classification--of this, the largest flowering family in the plant kingdom. The book is richly. that the section is divisible into four major elements: 1) Salix interior, 2) S.

taxifolia, 3) the S. exigua group, and 4) S. melanopsis. The first three occupy eastern, southern, and western portions of the continent, respectively.

Salix melanopsis is sympatric with the S. exigua group in western North America, but is ecologically distinct. The polyploid Salix alba–Salix fragilis hybrid complex is rather difficult to study when using only morphological characters.

Usually, sequences within individuals are uniformized due to concerted evolution [45–46]. However, in cases of recent hybridization or homoploid speciation, sequence homogenization is often not achieved in the short period of time involved [45–46].
