Book excerpt: Com o objetivo de caracterizar biologica e molecularmente o agente etiológico da malformação floral e vegetativa da mangueira no Brasil, foram utilizadas as técnicas de AFLP, compatibilidade sexual, análise de seqüências gênicas, bem como o estudo da morfologia e patogenicidade. Na análise de AFLP, os padrões de bandas para a maioria dos isolados coletados no Brasil foram diferentes daqueles de Fusarium mangiferae e Fusarium sterilihyphosum. O dendrograma gerado na análise de AFLP, utilizando o coeficiente de Dice, apresentou Fusarium sp. do Brasil em um grupo, enquanto que os outros grupos foram de isolados de F. sterilihyphosum do Brasil e da África do Sul, e de isolados de F. mangiferae da África do Sul, Egito, EUA e Índia, respectivamente. Fusarium sp. do Brasil foi comparado à 24 espécies do complexo Gibberella fujikuroi (CGF) por meio de AFLPs, comportando-se como uma espécie única. O dendrograma de UPGMA nesta análise foi muito semelhante à genealogia de genes do CGF, com três clados filogeográficos, americano, africano e asiático. Nos ensaios de compatibilidade sexual, isolados de Fusarium sp. do Brasil foram compatíveis entre si, mas não com F. sterilihyphosum e nem F. mangiferae. Foram observados peritécios típicos de Gibberella exsudando ascósporos nos cruzamentos de Fusarium sp. do Brasil. Análises de fragmentos de seqüências de [beta]-tubulina e fator de elongação-1[alpha] foram utilizadas para determinar as relações filogenéticas entre Fusarium sp. do Brasil e espécies do CGF. Na análise de máxima parcimônia, Fusarium sp. do Brasil agrupou no clado americano, mas, como sendo uma espécie distinta próxima a F. sterilihyphosum. Na caracterização morfológica, observou-se a presença de hifa estéril espiralada em alguns isolados de Fusarium sp. do Brasil, o mesmo ocorrendo para F. sterilihyphosum, sendo difícil separá-las com base apenas em morfologia. Entretanto, podem ser facilmente separadas por padrões de AFLP, fertilidade e análise de seqüências gênicas. Fusarium mangiferae não foi detectado nas amostras com malformação obtidas no Brasil. Isolados de Fusarium sp. do Brasil e F. sterilihyphosum induziram sintomas típicos de malformação quando inoculados em mudas de mangueira. Uma nova espécie de Gibberella, associada à malformação da mangueira no Brasil, será descrita.

Available in PDF, EPUB and Kindle. Book excerpt: Malformation disease of mango (Mangifera indica) initially noted in patches in India has now turned into a global menace wherever mango is grown. The challenge posed by the problem attracted interest of Scientists from various disciplines, continue to do so, and will attract their attention until the problem is understood threadbare, and resolved. For a long time, due to complex nature of the disease, the cause and causal agent was both hotly debated. Only in recent years, the issue of the etiology of the disease has been resolved, epidemiology has been worked out to a large extent and silver bullet control measures have been replaced by IPM strategy based on the information generated on the physiology of pathogenesis and epidemiology of the disease.

This book was released on 2016 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many mango-growing countries, mango blossom malformation or Mango Malformation Disease (MMD), caused by Fusarium spp., is the foremost impediment to viable orchards. This disease, which is one of the most destructive in nature, is of major concern in South Africa. The fungal species responsible for the disease varies substantially worldwide, therefore the species responsible for the disease in South Africa has to be confirmed. In the last two decades, biocontrol agents have emerged as potential, effective strategies of disease control for several crops. In order to fully understand the efficacy of such biocontrol agents, a thorough study of the dynamics of the interaction between the biocontrol agents, the pathogen and the host, was required. The aim of this study was the identification of the Fusarium spp. responsible for MMD in South African mango orchards, as well as the screening of microorganisms for their ability to control the pathogen. The modes of action of the best screened antagonists and a commercial biocontrol product were determined, with focus on induced resistance.

Download or read book Taxonomy and Population Genetics of Fusarium Subglutinans Sensu Lato on Pine and Mango written by Henriette Britz Van Heerden and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fusarium subglutinans sensu lato is a complex of fungi, which are the causal agents of important diseases on a wide variety of plants. Two important diseases caused by F. subglutinans sensu lato are pitch canker and mango malformation. F. subglutinans sensu lato isolates causing pitch canker on pine trees have been described as a separate species, F. circinatum. whereas F. subglutinans sensu lato isolates associated with mango malformation have not been formally described. The objective of study was to clarify the taxonomy and population genetics of the pitch canker and mango malformation fungi residing in the Gibberellafujikuroi complex. The introductory chapter of this thesis provides a review of the taxonomic classifications used for Fusarium spp. in the G. fujikuroi complex. In addition, the current knowledge pertaining to the population structure of the pitch canker and mango malformation fungi is discussed. In the second chapter the occurrence of F. circinatum was investigated in Mexico. Fusarium isolates were collected from pine trees in Mexico and identified as F. circinatum. Morphology, sexual compatibility studies, pathogenicity tests and histone H3-RFLPs were used to identify and characterize this fungus. The pitch canker fungus, F. circinatum and its teleomorph, G. circinata has been recently described. However, the name G. circinata is invalid, because insufficient information was provided to characterize the type specimen in the description. Additional information and a selection of F. circinatum isolates were, therefore, obtained and studies were undertaken in order to validate the description of G. circinata. The teleomorph G. circinata was validated and morphological criteria were shown to clearly distinguish F. circinatum from other F. subglutinans sensu lato isolates. Chapter four presents a study aimed at better understanding relationships between populations of F. circinatum from different geographical areas. For this study co dominant molecular markers were developed. These were then used to determine the genetic diversity, genetic distance and migration between different F. circinatum populations. Analysis revealed a high diversity in the Florida population and a low diversity in the South African population. Genetic analysis also indicated that the South African F. circinatum population originated in Mexico. In chapter five, the influence of sexual reproduction on the F. circinatum populations sampled over ten years in South Africa were studied. Sexual compatibility, vegetative compatibility and allelic diversity that were determined using polymorphic markers, developed in chapter four, were used. These results suggested that sexual reproduction is occurring more frequently in the more recently collected populations than in the initial population. Mango malformation is an important disease in mango growing areas. The study presented in chapter six indicated that this disease is associated with two distinct Fusarium spp. in the section Liseola. The two new Fusarium spp. are thus described as F. mangiferae and F. sterilihyphosum using morphological criteria In chapter seven, the distribution and vegetative compatibility of both F. mangiferae and F. sterilihyphosum was determined for the South Africa populations. Results revealed that each of these species differ in their distribution in South Africa. Vegetative compatibility tests also suggest that both species represent single genets in South Africa. Fusarium subglutinans sensu lato isolates associated with pme and mango are economically important fungi. The focus of the studies presented in this thesis has been on the taxonomy and population genetics of these fungi, with special reference to their occurrence in South Africa. Each of the chapters will contributes towards a better understanding of the taxonomy, population genetics and biology of these fungi.

Book excerpt: The Mango is one of the oldest cultivated fruit crops, having been grown in India for at least 4000 years. Mango is the most important fruit crop of Asia and its annual production is exceeded worldwide only by Musa, citrus, grapes and apples. The last decade has seen a rapid growth of mango production, mainly due to expansion into new growing regions but also to the adoption of modern field practices and cultivars. A wide range of fresh, mango cultivars are now consumed worldwide and are available year round. The Mango: Botany, Production and Uses, published in 1997, represented the first comprehensive examination of all aspects of modern mango production and research. Developing upon the successful first edition, this book incorporates a discussion of significant advances in mango research that have contributed to improved production and will be highly relevant for researchers and growers alike.

Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.

Download or read book The Fusarium Laboratory Manual written by John F. Leslie and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time in over 20 years, a comprehensive collection of photographs and descriptions of species in the fungal genus Fusarium is available. This laboratory manual provides an overview of the biology of Fusarium and the techniques involved in the isolation, identification and characterization of individual species and the populations in which they occur. It is the first time that genetic, morphological and molecular approaches have been incorporated into a volume devoted to Fusarium identification. The authors include descriptions of species, both new and old, and provide protocols for genetic, morphological and molecular identification techniques. The Fusarium Laboratory Manual also includes some of the evolutionary biology and population genetics thinking that has begun to inform the understanding of agriculturally important fungal pathogens. In addition to practical “how-to” protocols it also provides guidance in formulating questions and obtaining answers about this very important group of fungi. The need for as many different techniques as possible to be used in the identification and characterization process has never been greater. These approaches have applications to fungi other than those in the genus Fusarium. This volume presents an introduction to the genus Fusarium, the toxins these fungi produce and the diseases they can cause. "The Fusarium Laboratory Manual is a milestone in the study of the genus Fusarium and will help bridge the gap between morphological and phylogenetic taxonomy. It will be used by everybody dealing with Fusarium in the Third Millenium." --W.F.O. Marasas, Medical Research Council, South Africa
