This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The mid-west of Western Australia is a hotspot for plant species biodiversity, with many rare or short range endemic species. It is also heavily impacted by mining activities, which combined make conservation a priority. This thesis aims to assess the potential of high-throughput sequencing of chloroplast genomes to underpin the conservation genetics of the highly diverse and speciose genus Acacia (Fabaceae). This thesis focuses firstly on establishing a fully sequenced chloroplast genome for the Acacia genus, which also represents the first fully sequenced chloroplast genome of the Mimosoideae subfamily. The genome was compared to previously sequenced Fabaceae chloroplast genomes, all of which occur in the Papilionoideae subfamily and display significant rearrangements relative to Acacia. The key finding of these comparisons was the highly divergent nature of the A. ligulata clpP1 gene, which is extremely unusual in such a highly conserved gene. Using the A. ligulata genome as a reference, chloroplast genomes from an additional 64 Acacia species were sequenced and assembled. These genomes were used in a phylogenetic analysis of the genus, and the integration of these genome sequences with previously sequenced small amplicon sequences from throughout the Acacia genus was investigated. The results of this study suggested that the integration of these vastly different sized sequence types has the ability to significantly improve poorly supported phylogenies, particularly when utilising a whole chloroplast genome phylogeny as a constraint upon the shorter sequences. Further investigation of the Acacia clpP1 gene was performed using the full complement of Acacia chloroplast genome sequences. This study found that divergence in the gene was present throughout the genus with four clades in particular exhibiting extreme divergence, indicated by mutations in the ClpP1 catalytic site. Additionally, two clpP1 pseudogenes (one plastid and one nuclear) were identified in two different Acacia clades. Sequencing of the A. ligulata transcriptome ruled out the possibility of a functional nuclear clpP1 gene in this species, suggesting that despite its unusual sequence, the divergent plastid clpP1 gene is likely to be functional. Finally, this thesis tested whether the whole chloroplast genome was better able to distinguish between species than traditional DNA barcoding loci. The results of this study indicated that the whole chloroplast genome provided a better means of sequence based identification than the matK and rbcL barcodes, with 19 out of 26 currently recognised taxa distinguished using the chloroplast genome sequences compared to 14 and 8 taxa distinguished using matK and rbcL, respectively. This thesis has significantly increased our knowledge of Acacia chloroplast genome structure and content, provides a reference for further chloroplast genetics research in the Acacia genus, solidifies the backbone of the Acacia phylogeny, and takes a first step towards whole chloroplast genome DNA barcoding in Acacia, all of which informs our conservation of Acacia species.

Download or read book Isozymes in Plant Genetics and Breeding written by and published by Elsevier. This book was released on 2012-12-02 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developments in Plant Genetics and Breeding, 1A: Isozymes in Plant Genetics and Breeding, Part A focuses on the advancements in the processes, methodologies, and approaches involved in the study of isozymes, including its role in plant genetics and breeding. The selection first elaborates on the historical perspectives of plant isozymes, plant genetics, and isozyme systems to study gene regulation during development. Discussions focus on the use of isozyme and similar comparisons to study differential gene regulation, gene preservation, dissemination of cultivars, propagation of cultivars and breeding lines, and studies on the effect of viral infection and hormones on isozyme expression. The text then examines allozymes in gene dosage studies, gene mapping, and plastid isozymes. The manuscript takes a look at the genetics of mitochondrial isozymes, evolution of plant isozymes, and detection of somatic variation. Topics include evolution of isozymes in plants, generation of isozymes, glutamate dehydrogenase, glutamate-oxaloacetate transaminase, and malate dehydrogenase. The text also ponders on enzyme activity staining, isozymic variation and plant breeders' rights, genetic purity of commercial seed lots, and use of isozymes in plant disease research. The selection is a valuable reference for researchers interested in the role of isozymes in plant genetics and breeding.

Download or read book Agroforestry for Natural Resource Management written by Ian Nuberg and published by CSIRO PUBLISHING. This book was released on 2009-05-18 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: In its early days, agroforestry may have been viewed as the domain of the 'landcare enthusiast'. Today, integrating trees and shrubs into productive farming systems is seen as a core principle of sustainable agriculture. Agroforestry for Natural Resource Management provides the foundation for an understanding of agroforestry practice in both high and low rainfall zones across Australia. Three major areas are discussed: environmental functions of trees in the landscape (ecosystem mimicry, hydrology, protection of crops, animals and soil, biodiversity, aesthetics); productive functions of trees (timber, firewood, pulp, fodder, integrated multi-products); and the implementation of agroforestry (design, evaluation, establishment, adoption, policy support). The book also includes a DVD that features videos on forest measurement and harvesting, a Farm Forestry Toolbox and many regionally specific agroforestry resources. Written by leading researchers and practitioners from around Australia, Agroforestry for Natural Resource Management will be an essential resource for students in agroforestry courses, as well as a valuable introduction to the field for professionals in related areas.

Download or read book The Biology of Island Floras written by David Bramwell and published by Cambridge University Press. This book was released on 2011-07-21 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.

Download or read book Advanced Molecular Genetics written by Alfred Pühler and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of powerful new techniques and refmements of tech niques in molecular genetics in recent years, and the surge in interest in biotechnology based on genetic methods, have heralded a new golden age in molecular genetics, and stimulated in diverse disciplines much interest in the technologies themselves and their potential uses in basic and applied biomedical sciences. Although some excellent specialist laboratory manuals (especially the Cold Spring Harbor Laboratory manuals by I. H. Miller; R. W. Davies et al. ; and T. Maniatis et al. ) on certain chapters of molecular genetics exist, no general text that covers a broad spectrum of the sub ject has thus far been published. The purpose of this manual is to pre sent most, though of necessity not all of the important methods of molecular genetics, in a series of simple experiments, many of which can be readily accomplished by the microbiologist, biochemist or biotechnologist that has had only limited exposure to genetics. The remainder of the experiments require either greater familiarity with the subject, or guidance by someone with such experience. The book should, therefore, not only enable individuals to acquire new proce dures for ongoing projects, but also serve as a basis for the teaching of molecular genetic techniques in formal predoctoral and postdoctoral laboratory courses.
