This study is comprising about 70% of the world trading market (Song et aimed to develop microbial control agents useful for the al., 2009a, 2009b). The cultivation area of cacti in Korea control of the bipolaris stem rot. Two bacteria (GA1-23 was 38.3 ha in 1990, increased to 50.2 ha in 2000, and and GA4-4) selected out of 943 microbial isolates because reached 73.7 ha, with a production of 29 million plants in of their strong antibiotic activity against B. cactivora were identified as Bacillus subtilis and B. amylolique- 2004 (Jeong et al., 2004). faciens The grafted cactus is cultivated in a greenhouse with , respectively, by the cultural characteristics, Biolog o program and 16S rRNA sequencing analyses. -

Groenewald, [email protected] Abstract: The genus Cercospora contains numerous important plant pathogenic fungi from a diverse range of hosts. Most species of Cercospora are known only from their morphological characters in vivo. Although the genus contains more than 5 000 names, very few cultures and associated DNA sequence data are available. In this study, 360 Cercospora isolates, obtained from 161 host species, 49 host families and 39 countries, were used to compile a molecular phylogeny. Partial sequences were derived from the internal transcribed spacer regions and intervening 5.8S nrRNA, actin, calmodulin, histone H3 and translation elongation factor 1-alpha genes. -

Coconut Bud Rot (140)
Pacific Pests, Pathogens and Weeds - Online edition Coconut bud rot (140) Common Name Coconut bud rot Scientific Name Phytophthora palmivora. Note, there may be more than one species of Phytophthora in the Pacific islands causing bud rot. For instance, Phytophthora hevae is also said to occur, causing a bud and nut rot of coconuts in New Caledonia (Photos 2&3). Distribution The disease is reported wherever coconuts are grown. It is recorded on coconut from Cook Islands, Fiji, Papua New Guinea, Samoa, Tonga, and Vanuatu. The report from Tonga needs confirmation. Hosts Photo 1. Bud rot of coconut showing the collapse of the spear and younger leaves due Bud rot occurs on coconut and other palms (e.g., betel nut, oil palm), to infection by Phytophthora palmivora, while the older leaves appear relatively healthy at this but Phytophthora palmivora infects many other crops (e.g., cocoa and papaya), as well as weeds, time. in Pacific island countries. Symptoms & Life Cycle By the time symptoms appear, the disease is advanced with rotting of the bud and inner leaves (Photo 1). The first sign is a wilt or a bending of the spear leaf; sometimes the spear leaf becomes light green, but not always. The outer leaves then start to yellow from the top of the fronds downwards, and then turn brown. Yellow to light brown, sunken patches occur on the leaf stalks. As the disease progresses, the central leaves fall out as they become completely rotten at the base of the leaf stalks, leaving only a few outer leaves, which remain green for a while. -

This work investigated the species diversity of these pathogens in Morocco, where Dickeya pathogens have only been isolated from potato fields recently. To this end, samplings were conducted in three major potato growing areas over a three-year period (2015–2017). Pathogens were characterized by sequence determination of both the gapA gene marker and genomes using Illumina and Oxford Nanopore technologies. -
Effect of Nutrition and Soil Function on Pathogens of Tropical Tree Crops
10 Effect of Nutrition and Soil Function on Pathogens of Tropical Tree Crops Peter McMahon Department of Botany, La Trobe University, Bundoora Vic Australia 1. Introduction Crops grown in the tropics are subject to different kinds of disease pressure from those produced in temperate regions. The greater biodiversity found in the tropics, including diversity of fungi, is reflected by the larger number of pathogen species in tropical regions (see Ploetz, 2007; Wellman, 1968, 1972). Perennial crops, and tropical perennials in particular, have features in common that may predispose them to pathogen infections. Pathogen inocula, such as microsclerotia, may build up from year to year in perennial crops (Pennypacker, 1989). Also, tropical conditions are usually suitable for the year-round survival and propagation of pathogen species, unlike temperate climates which have a cooler season when pathogen populations die off or are reduced. Tropical perennial crops often include susceptible genotypes on the farm and the presence of susceptible host material encourages the production of inoculum and the initiation of new infections (Ploetz, 2007). Ploetz (2007) remarks that the presence of susceptible hosts is a particularly important barrier to disease control in tropical perennials. Diseases in the tropics may be complicated by interactions between different pathogens, or between pathogens and insect pests (Holliday, 1980; Ploetz, 2006; Vandermeer et al., 2010; Anonymous, 2010). Disease complexes involving a number of fungal pathogens or fungi and nematodes are common in tropical situations. Interactions between pathogens and environmental stress may also occur. Crops can become more susceptible to pathogen infections when weakened by environmental stress such as drought, temperature extremes, and exposure to sunlight or wind (Agrios, 2005). -

Tsetse fly evolution, genetics and the trypanosomiases - A review Abstract This reviews work published since 2007. Relative efforts devoted to the agents of African trypanosomiasis and their tsetse fly vectors are given by the numbers of PubMed accessions. In the last 10 years PubMed citations number 3457 for Trypanosoma brucei and 769 for Glossina. The development of simple sequence repeats and single nucleotide polymorphisms afford much higher resolution of Glossina and Trypanosoma population structures than heretofore. Even greater resolution is offered by partial and whole genome sequencing. Reproduction in T. brucei sensu lato is principally clonal although genetic recombination in tsetse salivary glands has been demonstrated in T. b. brucei and T. b. rhodesiense but not in T. b. -

Crous, [email protected] Abstract: Septoria represents a genus of plant pathogenic fungi with a wide geographic distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. A major aim of this study was to resolve the phylogenetic generic limits of Septoria, Stagonospora, and other related genera such as Sphaerulina, Phaeosphaeria and Phaeoseptoria using sequences of the the partial 28S nuclear ribosomal RNA and RPB2 genes of a large set of isolates. Based on these results Septoria is shown to be a distinct genus in the Mycosphaerellaceae, which has mycosphaerella-like sexual morphs. Several septoria-like species are now accommodated in Sphaerulina, a genus previously linked to this complex. -
