The new Passalora species differs from congeneric species on members of Acanthaceae by its external hyphae giving rise to conidiophores. The new Periconiella species can be distinguished from other species of the genus by its conidiogenous cells being conspicuously oriented outwards from the conidiophore head and by its sizes being intermediate between those of P. machilicola on the one hand and of P. longispora and P. rapaneae on the other. Anamorphic Dothideomycetes (Ascomyocta) / microfungi / Mycosphaerella / neotropics INTRODUCTION Plant-associated hyphomycetes with relationships to Mycosphaerella and related taxa of Dothideomycetes (Ascomycota) are generally considered cercosporoid fungi with frequently changing generic concepts. Reviews and keys of the present stage of generic concepts in the cercosporoid hyphomycetes are provided by Crous & Braun (2003). Species of two genera with pigmented conidiophores and conidia with blackened conidiogenous loci and conidial hila are treated in this study, namely of Passalora and Periconiella. Species of Periconiella are additionally characterized by conidiophores differentiated into a stipe and head composed of branches and conidiogenous cells. -
A Review of Coconut Research and Development
A REVIEW OF COCONUT RESEARCH & DEVELOPMENT By Hugh C. Harries1 INTRODUCTION By looking at the titles of articles published in CORD since it began, in 1985, it should be possible to assess what areas of coconut research and development are important. This is so, because CORD is intended for a select group of readers - those who know about coconuts. The writers of articles for CORD, unlike authors of articles in specialist scientific or economic journals, do not have to compete for space with reports on the cutting-edge of science or with predictions about world- market economic forces. Which is a pity, because if they did it would mean that coconut was back in the position of the world's leading source of vegetable oil that it held for half a century. There are other technical and scientific journals, as well as national language publications, to which coconut R&D specialist can, and do, submit articles, but CORD is the one location where both the writer and the reader should be on the same wavelength. For the purposes of this review the titles have been grouped into sub-sets to give some idea of the relative degree of interest or apparent importance of different topics (assuming that the title reflects the content accurately). It is also unavoidable that some titles might be placed into more than one category. For example "Genetic & seasonal variation in coconut production" is either agronomy or breeding. The present review reflects this author's prejudices. Other readers can make their own groupings from the lists of titles contained in the tables that follow. -
Integrated Disease and Pest Management in Coconut by the Application of Biocides from Medicinal Herbs
CLEAR International Journal of Research in Management, Science and Technology Vol-1 No-1 Jan-Jun 2011 Integrated Disease and Pest Management in Coconut by the Application of Biocides from Medicinal Herbs Dr. Susmita Sahoo1, Dr. S. Sahoo2 and Dr. P.S. Mukherjee2 1 N.V. Patel College Pure & Applied Sciences, V.V. Nagar, Anand, Gujarat ,India. [email protected] 2 Regional Research Laboratory (CSIR), Bhubaneshwar - 751013. Orissa,India. Abstract Coconut (Cocos nucifera L.) is the chief source of healthy natural drink rich in multiuse nutritional food and oil producing tree of Nature found in Asia & Pacific Regions including 93 coconut growing countries. India has 1.0 million hectares cultivable plantation area with 12.8 billion annual nuts production. Though optimized agro technology boosts its productivity, infestation by pests & diseases drastically reduce the crop product. Among the diseases grey leaf spot is a wide spread disease in tropics in young & aged plants. It is caused by Pestaloptiopsis palmarum. The Eriophyid mite (Aceria guerrerouis Keife) restricts nut formation to nut production & overall nut quality in coconut. In the present study at RRL, Bhubneswar, a holistic approach has been done to eradicate the pest & desease in coconut by biocides formulated from herbal sources like Hyptis, Ocimum, Andrographis, Patchouli & Citronella. For mite the application is through spray fumigation & soil incorporation. For the fungal infection crude plant extract (1%) was found effective in inhibiting the fungal growth. Keywords: (botanical pesticides, essential oils, herbal plants, eco-friendly) by perianth. The chemicals that found favour with the farmers Introduction during the initial years were monocrotophos (root feeding or stem injection), dicofol, endosulfan and ethion. -
A Mechanistic Weather-Driven Model for Ascochyta Rabiei Infection and Disease Development in Chickpea
plants Article A Mechanistic Weather-Driven Model for Ascochyta rabiei Infection and Disease Development in Chickpea Irene Salotti and Vittorio Rossi * Department of Sustainable Crop Production (DI.PRO.VES.), Università Cattolica del Sacro Cuore, Via E. Parmense 84, 29122 Piacenza, Italy; [email protected] * Correspondence: [email protected] Abstract: Ascochyta blight caused by Ascochyta rabiei is an important disease of chickpea. By using systems analysis, we retrieved and analyzed the published information on A. rabiei to develop a mechanistic, weather-driven model for the prediction of Ascochyta blight epidemics. The ability of the model to predict primary infections was evaluated using published data obtained from trials conducted in Washington (USA) in 2004 and 2005, Israel in 1996 and 1998, and Spain from 1988 to 1992. The model showed good accuracy and specificity in predicting primary infections. The probability of correctly predicting infections was 0.838 and the probability that there was no infection when not predicted was 0.776. The model’s ability to predict disease progress during the growing season was also evaluated by using data collected in Australia from 1996 to 1998 and in Southern Italy in 2019; a high concordance correlation coefficient (CCC = 0.947) between predicted and observed data was obtained, with an average distance between real and fitted data of root mean square error (RMSE) = 0.103, indicating that the model was reliable, accurate, and robust in predicting seasonal dynamics of Ascochyta blight epidemics. The model could help growers schedule fungicide treatments to control Ascochyta blight on chickpea. Citation: Salotti, I.; Rossi, V. -

Draft Genome Sequencing and Secretome Analysis of Fungal
www.nature.com/scientificreports OPEN Draft genome sequencing and secretome analysis of fungal phytopathogen Ascochyta Received: 28 October 2015 Accepted: 04 April 2016 rabiei provides insight into the Published: 19 April 2016 necrotrophic effector repertoire Sandhya Verma, Rajesh Kumar Gazara, Shadab Nizam, Sabiha Parween, Debasis Chattopadhyay & Praveen Kumar Verma Constant evolutionary pressure acting on pathogens refines their molecular strategies to attain successful pathogenesis. Recent studies have shown that pathogenicity mechanisms of necrotrophic fungi are far more intricate than earlier evaluated. However, only a few studies have explored necrotrophic fungal pathogens. Ascochyta rabiei is a necrotrophic fungus that causes devastating blight disease of chickpea (Cicer arietinum). Here, we report a 34.6 megabase draft genome assembly of A. rabiei. The genome assembly covered more than 99% of the gene space and 4,259 simple sequence repeats were identified in the assembly. A total of 10,596 high confidence protein-coding genes were predicted which includes a large and diverse inventory of secretory proteins, transporters and primary and secondary metabolism enzymes reflecting the necrotrophic lifestyle ofA. rabiei. A wide range of genes encoding carbohydrate- active enzymes capable for degradation of complex polysaccharides were also identified. Comprehensive analysis predicted a set of 758 secretory proteins including both classical and non-classical secreted proteins. Several of these predicted secretory proteins showed high cysteine content and numerous tandem repeats. Together, our analyses would broadly expand our knowledge and offer insights into the pathogenesis and necrotrophic lifestyle of fungal phytopathogens. Chickpea (Cicer arietinum L.), an important high-protein source, is an annual legume crop grown worldwide. -
Inventory and Review of Quantitative Models for Spread of Plant Pests for Use in Pest Risk Assessment for the EU Territory1
EFSA supporting publication 2015:EN-795 EXTERNAL SCIENTIFIC REPORT Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory1 NERC Centre for Ecology and Hydrology 2 Maclean Building, Benson Lane, Crowmarsh Gifford, Wallingford, OX10 8BB, UK ABSTRACT This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application. First, we conducted an extensive literature review, based on protocols developed for systematic reviews. The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. A cluster analysis on how these models were formulated allowed us to identify eight distinct major modelling strategies that were differentiated by the types of pests they were used for and the ways in which they were parameterised and analysed. These strategies varied in their strengths and weaknesses, meaning that no single approach was the most useful for all elements of risk assessment. Therefore we developed a Decision Support Scheme (DSS) to guide model selection. The DSS identifies the most appropriate strategies by weighing up the goals of risk assessment and constraints imposed by lack of data or expertise. Searching and filtering the Electronic Model Inventory then allows the assessor to locate specific models within those strategies that can be applied. -

Bud Rot and Other Major Diseases of Coconut, a Potential Threat to Oil Palm
1 Bud rot and other major diseases of coconut, a potential threat to oil palm Dollet Michel1, Hubert de Franqueville2 Michel Ducamp1 1CIRAD, TA A-98/F, Campus International de Baillarguet, 34398 Montpellier Cedex 5 2PalmElit - Parc Agropolis Bat.14 - 2214 Bd de la Lironde, 34980 Montferrier sur Lez INTRODUCTION Since the last quarter of the 20th century, it has had to be accepted that any pathogen can move from one continent to another, in a very short time, and affect any place on the planet. The best-known examples are animal and/or human pathogens. Reference will briefly be made to them as they are very concrete examples of the current epidemic context. However, this also applies for the spread of plant diseases that we have been witness to in the last thirty years. Not only do pathogens travel over long distances, they also “jump hosts”, be it in the Animal Kingdom or the Plant Kingdom. Climate changes may be conducive to such events. Using these data, we shall attempt to examine the possible risks of seeing pathogens of the coconut palm, Cocos nucifera, or even of other plants, attacking the oil palm, Elaeis guineensis. DISPERSAL/PROPAGATION OF ANIMAL AND HUMAN PATHOGENS Sars The first example involves SARS (Severe Acute Respiratory Syndrome) which was identified in humans in China at the end of 2002. At the beginning of 2003, a hotel in Hong Kong very close to the original focus was the starting point for an epidemic that affected Vietnam, Singapore and even Toronto in Canada within a few weeks. -
