This book was released on 2012-12-06 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the beginning of this century the mutation theory of evolution, based by HUGO DE VRIES on many years of culture experiments mainly with Oenothera Lamarckiana, took the world by storm when published in 1901. As early as 1889 DE VRIES had shown that various plant "monstrosities" are inherited. His breeding experi ments with other plants involved the rediscovery of MENDEL'S laws and the resuscitation of MENDEL'S breeding methods, which had been in abeyance in the long period from 1865 to 1900. MENDEL began his crossing experiments in 1854, DE VRIES began his Oeno thera cultures in 1886. The genus Oenothera was thus the first after Pisum to be the subject of extensive genetic experiments. Thus was introduced the method now so widely pursued. It may be remembered also that DE VRIES drew the distinction between fluctuations and mutations, but he regarded all fluctuations or continuous variations as non-heritable. Both can be equated with the continuous and discontinuous variations of BATESON. DE VRIES' conception of mutations corresponds with the "single variations" of DARWIN, except that he regarded each mutation as producing a new elementary species, now generally called microspe cies. He said in the introduction to his Mutationstheorie, that the characters of organisms are built up from units which are as sharply distinguished from each other as the molecules of chemistry. These units can be united into groups, and in related species of plants and animals the same units and groups are repeated.

Available in PDF, EPUB and Kindle. Book excerpt: Because of the great variety of problems which this genus presents to biologists, Oenothera belongs to the best-known genera of plants not used economically. This book summarizes today's knowledge of Oenothera's genetics and related fields like caryology and cytogenetics. It is further of great value for all those whose research topics are based on genetics, such as developmental and evolutionary biology.

This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: "I use a target enrichment approach to produce the first well-supported molecular phylogeny of sect. Calylophus. In order to maximize phylogenetic information within the section, I sampled taxa across the known geographic and morphological range of each of the 13 currently recognized taxa and used HybPiper, a recently developed bioinformatics pipeline for targeted sequencing, to extract exons and flanking intron sequences from high-throughput sequencing reads. Here, I 1) test the current phylogenetic hypotheses and investigate the influence of pollinator shifts, independent origins of gypsum endemism and Pleistocene climate fluctuations on speciation in the group, and 2) further test the application of target enrichment for phylogenetic applications in recently radiated non-model group of plants. I found support for two independent shifts to bee pollination and two origins of gypsum endemism, indicating that both biotic and abiotic factors have played an important role in speciation in sect. Calylophus. These results largely support the morphologically-based phylogenic hypothesis. However, further work is needed to characterize the effects of hybridization and gene flow, as well as paleo-climatic fluctuations. This study presents the most comprehensive taxonomic sampling scheme that has been applied to target enrichment methods to-date, and has implications for other recalcitrant, non-model groups of plants."--Abstract
