Book excerpt: Flowering dogwood (Cornus florida L.) is prized as an ornamental and contributes millions of dollars to the economy through tourism and sales each year. Dogwood anthracnose, caused by Discula destructiva Redlin, was observed in the late 1970s on the east and west coasts of the United States and by 1991 had quickly spread throughout much of the native ranges of C. florida and C. nuttalli. The objectives of this study were to investigate the genetic diversity and population structure of D. destructiva using simple sequence repeats (SSRs), and to test the cross-transferability of these markers to other Discula species. Fifty SSRs were developed from the sequenced genome of a D. destructiva isolate and used to evaluate 93 fungal isolates from 14 locations collected between 1989 and 2000. The data set was clone corrected (n = 69) and analyzed using polymorphic only (n = 40) and polymorphic and monomorphic SSRs (n = 47). Haploid genetic diversity was very low for both data sets (Hexp = 0.18 and 0.21). Bayesian clustering and distance analyses identified four and five genetic clusters that correspond to two major geographic areas, the eastern United States and the Pacific Northwest, and two time periods when the isolates were collected, Pre-1993 and Post-1993. Linkage disequilibrium was present in all subpopulations, which strongly suggested that the fungus was only reproducing asexually. A population bottleneck was statistically indicated in all populations, and was probably the result of the limited number of founding individuals on both coasts. These results support the hypothesis that D. destructiva is an exotic pathogen with separate introductions on the east and west coasts of North America. The cross-transferability test revealed that genomic DNA from 19 isolates of five other Discula species and two isolates of Melanconis spp. amplified with 17 of 47 primer pairs. These primers may be useful for investigating the genetic diversity and population structure of these Discula species.

Download or read book Phylogenetic Relationships and Morphology of Cytospora Species and Related Teleomorphs (Ascomycota, Diaporthales, Valsaceae) from Eucalyptus written by Pedro W. Crous and published by . This book was released on 2005 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cytospora species and their Valsa teleomorphs are commonly found on Eucalyptus trees and some of these have been associated with stem canker diseases. The taxonomy of these fungi has been confused and has in many cases hindered pathology studies. This study was based on extensive collections of Cytospora species and their teleomorphs from Eucalyptus trees in Africa, Australia, Central and South America, Southeast Asia and California. Sixty-two Cytospora and three Cytospora-like isolates from Eucalyptus, yielding 33 unique ITS-rDNA sequences, were compared for homology to Cytospora species from other hosts. Phylogenetic analysis clustered isolates of Cytospora from Eucalyptus into at least 15 unrelated groups. The Cytospora-like isolates that morphologically resembled Cytospora clustered in a separate group, which is related to Phomopsis. Morphology of the fungi was examined on natural subtrates and in culture in order to identify distinctive characters linked to the phylogenetic lineages emerging from DNA sequence analyses. The specimens from Eucalyptus included morphological features encompassing the Cytospora infrageneric sections Cytospora, Lamyella, Leucocytospora, and Torsellia with the majority residing in sect. Lamyella. Several species exhibited morphological characteristics of more than one section and other species had unique characteristics not represented in the established sections. Phylogenetic inference did not support the sections that have been established based on morphological characteristics. The concepts underlying the establishment of sections in Valsa and Cytospora were, therefore, discarded and descriptive terms have been introduced to distinguish between ascostroma and locule forms. Descriptions of Cytospora australiae, C. eucalyptina, C. eucalypticola, and the anamorphs of Valsa eucalypti and Leucostoma sequoiae have been emended based on morphological studies of cross-sections of holotype and isotype specimens. Teleomorphs associated with Cytospora specimens on Eucalyptus have been described from Australia, California, Chile, Congo, Hawaii, India and Uganda. Each teleomorph had unique morphological characteristics and DNA sequence but several conformed to the broad description of Valsa ceratosperma, even though they resided in separate phylogenetic lineages. Additionally, sequences for V. ceratosperma on hosts other than Eucalyptus resided in separate lineages and were different from all of the isolates from Eucalyptus. One of the lineages, commonly found on Quercus, was recognised as corresponding to the original species concept and was designated as V. ceratosperma sensu stricto (= V. ceratophora). Results of this study have shown that numerous genetically distinct lineages of Cytospora and Cytospora-like fungi occur on Eucalyptus, and that the current description of V. ceratosperma encompases several distinctly different fungi. Leucostoma sequoiae and V. eugeniae were found on Eucalyptus, and V. eucalypti and L. sequoiae have been synonymised. Cultural characteristics including colony colour, pycnidium structure, cardinal temperatures for growth, and tolerance to cycloheximide have been described for the species. Several new species of Valsa and Cytospora from Eucalyptus have also been delimited based on morphological characteristics. This wide-ranging study should contribute to a better understanding of the taxonomy of Cytospora spp. and their teleomoprhs, particularly on Eucalyptus. It is also hoped that this will lead to improved management strategies for diseases associated with these fungi.

Available in PDF, EPUB and Kindle. Book excerpt: Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

Download or read book Abiotic Stress Adaptation in Plants written by Ashwani Pareek and published by Springer Science & Business Media. This book was released on 2009-12-12 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental insults such as extremes of temperature, extremes of water status as well as deteriorating soil conditions pose major threats to agriculture and food security. Employing contemporary tools and techniques from all branches of science, attempts are being made worldwide to understand how plants respond to abiotic stresses with the aim to help manipulate plant performance that will be better suited to withstand these stresses. This book on abiotic stress attempts to search for possible answers to several basic questions related to plant responses towards abiotic stresses. Presented in this book is a holistic view of the general principles of stress perception, signal transduction and regulation of gene expression. Further, chapters analyze not only model systems but extrapolate interpretations obtained from models to crops. Lastly, discusses how stress-tolerant crop or model plants have been or are being raised through plant breeding and genetic engineering approaches. Twenty three chapters, written by international authorities, integrate molecular details with overall plant structure and physiology, in a text-book style, including key references.
