Book excerpt: This book begins with an account of the early history of Phytophthora research and the tumultuous events setting the genus in motion. In keeping with its controversial inception, the chapter on taxonomy and phylogeny makes a compelling case that our current notion of Phytophthora as a genus is illusory. This chapter sets the stage for the importance of molecular tools on these enigmatic pathogens. The following chapters discuss species identification, population-level investigation, interspecific hybrids and the impact of diverse Phytophthora species on crops, forests, nurseries, greenhouses and natural areas worldwide.

Book Synopsis Inducing Suppressiveness to Phytophthora Root Rot of Avocado by Using Bioenhanced Mulches by : Jefferson Luis da Silva Costa
Download or read book Inducing Suppressiveness to Phytophthora Root Rot of Avocado by Using Bioenhanced Mulches written by Jefferson Luis da Silva Costa and published by . This book was released on 1995 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic mulches colonized with microbial biocontrol agents (BCAs), termed bioenchanced mulches, were tested for their ability to reduce Phytophthora root rot of avocado. The BCAs were first evaluated for their ability to colonize different mulches. Some of the possible specific mechanisms of P. cinnamomi suppression were investigated. Soils treated with mulches for more than 12 months under field and greenhouse conditions resulted in high levels of organic matter. Bioassays using tension plates and soil columns indicated that accumulation of organic matter in the soil trapped or inhibited movement of zoospores and reduced the disease incidence. Bioassays in Petri plates indicated that soils with high microbial activity reduced the survivability of P.cinnamomi zoospores.

This book was released on 2012 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Avocado (Persea americana Mill.) is a popular and nutritious crop and of great importance to the global fruit industry. One of the major problems encountered is the susceptibility of avocado trees to Phytophthora root rot (PRR) caused by the soil-born oomycete Phytophthora cinnamomi Rands. Control is achieved through an integrated control strategy that consists of mulching, chemical control in the form of phosphite injections and the use of resistant rootstocks. Emphasis is now placed on the use of resistant rootstock varieties to combat this devastating disease. Avocado breeding programmes around the world have provided growers with a selection of highly tolerant rootstocks such as Duke 7 and Dusa®. Despite the availability of tolerant material it has not yet been established why certain rootstocks display high levels of tolerance against P. cinnamomi and others not. Selecting resistant rootstocks is a time consuming process that can take up to 25 years. Due to the lack of research on the avocado/Phytophthora interaction, the aim of this dissertation was i) to establish a pathogenicity system that could be used to study the interaction ii) to investigate the expression profiles of selected defense-associated genes from five avocado rootstocks upon P. cinnamomi infection and lastly to develop an assay that could detect P. cinnamomi in planta that could be applied to aid in the selection process of tolerant avocado varieties. Chapter 1 entitled Plant defense mechanisms against Phytophthora provides an overview of plant defense responses against Phytophthora and where possible specifically against P. cinnamomi. General plant defense concepts including pathogen triggered immunity and specific effector triggered immunity is discussed. Both these immune responses are linked to other key players that regulate specific signalling pathways in order to achieve an effective defense response. Mechanisms involved in defense that are discussed include cell wall reinforcements, production of ion fluxes and ROS species, MAPK and phosphorylation cascades, rapid induction of defense genes, accumulation of defense-related proteins including phytoalexins and PR proteins which all negatively affect colonization of potential pathogens. Chapter 2 reports on the establishment of two reliable small plant inoculation systems for studying plant disease development in the greenhouse followed by subsequent molecular studies. Briefly a hydroponics system was evaluated to allow easy access to root material for RNA extractions followed by quantitative PCR and the second solid system was evaluated using perlite and vermiculite as growth substrates to assess disease development and severity in three avocado rootstocks with varying levels of resistance to PRR. In Chapter 3 the role of seven defense related genes were investigated in five avocado rootstocks after infection with P. cinnamomi. The expression of each individual gene was assessed over seven time points ranging from 0 to 72 hours using quantitative RT-PCR. Data were analyzed statistically to highlight differences amongst the five rootstocks with respect to their gene expression against the pathogen. Chapter 4 describes the development of a nested quantitative PCR that quantifies P. cinnamomi in planta in two avocado rootstocks displaying different levels of tolerance against this soil-borne oomycete. A nested primer set was developed for the Lpv gene that resulted in a P. cinnamomi – specific, sensitive assay that can be utilized to assess rootstock tolerance. The thesis concludes with a discussion (Chapter 5) on all the data generated during the course of this study, our findings and recommendations.

Book Synopsis Silicon and Plant Diseases by : Fabrício A. Rodrigues
Download or read book Silicon and Plant Diseases written by Fabrício A. Rodrigues and published by Springer. This book was released on 2015-10-15 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon, considered to be the second most abundant mineral element in soil, plays an important role in the mineral nutrition of plants. A wide variety of monocot and dicot species have benefited from silicon nutrition, whether direct or indirect, when they are exposed to different types of abiotic and or biotic stresses. Besides the many agronomic and horticultural benefits gained by maintaining adequate levels of this element in the soil and also in the plant tissue, the most notable effect of silicon is the reduction in the intensities of a number of plant diseases caused by biotrophic, hemibiotrophic and necrotrophic plant pathogens in many crops of great economic importance. The aim of this book is to summarize our current understanding of the effects of silicon on plant diseases. The chapters address the dynamics of silicon in soils and plants; the history of silicon in the control of plant diseases; the use of silicon to control soil-borne, seed-borne and foliar diseases in monocots and dicots; the mechanisms involved in the host resistance against infection by plant pathogens mediated by silicon as well as the current knowledge at the omics level, and finally, highlights and prospects for using silicon in the future.

Book Synopsis Polyphenol Oxidases (PPOs) in Plants by : Aravind Jukanti
Download or read book Polyphenol Oxidases (PPOs) in Plants written by Aravind Jukanti and published by Springer. This book was released on 2017-08-18 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is first of its kind exclusively dedicated to plant polyphenol oxidases (PPOs), highlighting their importance in the food processing industry. By reviewing the scientific developments of the past several decades, it offers a comprehensive overview of various aspects of plant PPOs, including chemistry, structure, functions, regulation, genetics/genomics and molecular aspects. PPOs are copper-containing proteins found in several plant species that catalyze the hydroxylation of o-monophenols to o-diphenols and oxidation of the o-dihydroxyphenols to o-quinones. Further, the quonines undergo self-polymerization or react with amines/thiol groups to produce brown/dark coloration of products. All the PPOs contain two Cu-binding sites (CuA and CuB) as their central domain, these interact with phenolic substrates and molecular oxygen. Several of the plant PPOs contain an N-terminal transit peptide (~80-100 amino acids ) necessary for plastid import. The PPOs occur in latent form that are activated by various treatments including acid and base shock, exposure to detergents or proteolytic degradation. The pH optimum of PPOs varies widely depending upon different plant species but is usually ~4.0 – 8.0. Similarly, the optimum temperature also varies as per the source and substrate involved ranging from 30 to 45 °C. Multiple PPO isoforms have been reported in several plant species, and the chromosomal location of PPOs has also been studied in some species. The physiological role (s) of PPOs is not entirely understood, but they could be involved in defense-related functions in plants. From an applied perspective, PPOs are implicated in enzymatic browning/darkening of cereal products, vegetables and fruits. Interestingly, browning is preferred in some instances like the processing of black tea, cocoa, and coffee as it enhances their quality by forming flavorful products. There have b een initiatives to specifically breed and develop cultivars with reasonably low PPO levels in the mature grain or fruit. Further, several types of inhibitors that reduce the PPO activity have also been identified. Despite their commercial/economic importance and the availability of literature on different aspects of PPOs in different plant species, this is the first book to provide basic information regarding PPOs. It is a valuable resource for researchers involved in quality-related research specifically in crops, vegetables and fruits. Further, as PPOs are also implicated in defense- or stress-related functions, the book is also useful to breeders, pathologists, molecular biologists, physiologists and entomologists.
