  • The powdery mildews: a review of the world's most familiar (yet poorly known) plant pathogens.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-08-06
    Dean A Glawe

    The past decade has seen fundamental changes in our understanding of powdery mildews (Erysiphales). Research on molecular phylogeny demonstrated that Erysiphales are Leotiomycetes (inoperculate discomycetes) rather than Pyrenomycetes or Plectomycetes. Life cycles are surprisingly variable, including both sexual and asexual states, or only sexual states, or only asexual states. At least one species

  • The origin of Ceratocystis fagacearum, the oak wilt fungus.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-08-06
    Jennifer Juzwik,Thomas C Harrington,William L MacDonald,David N Appel

    The oak wilt pathogen, Ceratocystis fagacearum, may be another example of a damaging, exotic species in forest ecosystems in the United States. Though C. fagacearum has received much research attention, the origin of the fungus is unknown. The pathogen may have been endemic at a low incidence until increased disturbances, changes in land use, and forest management created conditions favorable for disease

    Starting with the influences of having a father who was an agricultural plant pathologist, I sketch my career through university and research institute from field epidemiology, basic virus characterization to molecular biology. I note what I consider to be the highlights of my scientific career and the events that shaped the development of my thinking. These include secondment to teach in a university

  • Plant viruses as biotemplates for materials and their use in nanotechnology.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-05-14
    Mark Young,Debbi Willits,Masaki Uchida,Trevor Douglas

    In recent years, plant virus capsids, the protein shells that form the surface of a typical plant virus particle, have emerged as useful biotemplates for material synthesis. All virus capsids are assembled from virus-coded protein subunits. Many plant viruses assemble capsids with precise 3D structures providing nanoscale architectures that are highly homogeneous and can be produced in large quantities

  • Identification and rational design of novel antimicrobial peptides for plant protection.

    Jose F Marcos,Alberto Muñoz,Enrique Pérez-Payá,Santosh Misra,Belén López-García

    Peptides and small proteins exhibiting antimicrobial activity have been isolated from many organisms ranging from insects to humans, including plants. Their role in defense is established, and their use in agriculture was already being proposed shortly after their discovery. However, some natural peptides have undesirable properties that complicate their application. Advances in peptide synthesis and

  • Breaking the barriers: microbial effector molecules subvert plant immunity.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-04-22
    Vera Göhre,Silke Robatzek

    Adaptation to specialized environments allows microorganisms to inhabit an enormous variety of ecological niches. Growth inside plant tissues is a niche offering a constant nutrient supply, but to access this niche, plant defense mechanisms ranging from passive barriers to induced defense reactions have to be overcome. Pathogens have to break several, if not all, of these barriers. For this purpose

  • Role of stomata in plant innate immunity and foliar bacterial diseases.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-04-22
    Maeli Melotto,William Underwood,Sheng Yang He

    Pathogen entry into host tissue is a critical first step in causing infection. For foliar bacterial plant pathogens, natural surface openings, such as stomata, are important entry sites. Historically, these surface openings have been considered as passive portals of entry for plant pathogenic bacteria. However, recent studies have shown that stomata can play an active role in limiting bacterial invasion

  • Living in two worlds: the plant and insect lifestyles of Xylella fastidiosa.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-04-22
    Subhadeep Chatterjee,Rodrigo P P Almeida,Steven Lindow

    Diseases caused by Xylella fastidiosa have attained great importance worldwide as the pathogen and its insect vectors have been disseminated. Since this is the first plant pathogenic bacterium for which a complete genome sequence was determined, much progress has been made in understanding the process by which it spreads within the xylem vessels of susceptible plants as well as the traits that contribute

  • Yeast as a model host to explore plant virus-host interactions.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2008-04-22
    Peter D Nagy

    The yeast Saccharomyces cerevisiae is invaluable for understanding fundamental cellular processes and disease states of relevance to higher eukaryotes. Plant viruses are intracellular parasites that take advantage of resources of the host cell, and a simple eukaryotic cell, such as yeast, can provide all or most of the functions for successful plant virus replication. Thus, yeast has been used as a

    Neil Boonham,Jenny Tomlinson,Rick Mumford

    Many factors affect the development and application of diagnostic techniques. Plant viruses are an inherently diverse group that, unlike cellular pathogens, possess no nucleotide sequence type (e.g., ribosomal RNA sequences) in common. Detection of plant viruses is becoming more challenging as globalization of trade, particularly in ornamentals, and the potential effects of climate change enhance the

  • Identifying microorganisms involved in specific pathogen suppression in soil.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2007-05-18
    James Borneman,J Ole Becker

    Suppressive soils hold considerable potential for managing soilborne pathogens. When the suppressiveness has a biological origin, identifying the causal organisms is the crucial step in realizing this potential. Armed with such knowledge, it may be possible to develop effective and sustainable pest management strategies through application of these organisms or agronomic practices that influence their

  • Elicitors, effectors, and R genes: the new paradigm and a lifetime supply of questions.
    Annu. Rev. Phytopathol. (IF 12.623) Pub Date : 2007-05-18
    Andrew F Bent,David Mackey

    The plant basal immune system can detect broadly present microbe-associated molecular patterns (MAMPs, also called PAMPs) and induce defenses, but adapted microbes express a suite of effector proteins that often act to suppress these defenses. Plants have evolved other receptors (R proteins) that detect these pathogen effectors and activate strong defenses. Pathogens can subsequently alter or delete

    A major challenge facing agricultural scientists today is the need to secure food for an increasing world population. This growth occurs predominantly in developing, mostly tropical countries, where the majority of hungry people live. Reducing yield losses caused by pathogens of tropical agricultural crops is one measure that can contribute to increased food production. Although plant-parasitic nematodes
