Diseases of Rice Fungal Diseases Blast - Pyricularia oryzae (Syn: P. grisea) (Sexual stage: Magnaporthe grisea) Symptoms The fungus attacks the crop at all stages of crop growth. Symptoms appear on leaves, nodes, rachis, and glumes. On the leaves, the lesions appear as small bluish green flecks, which enlarge under moist weather to form the characteristic spindle shaped spots with grey centre and dark brown margin (Leaf blast). The spots coalesce as the disease progresses and large areas of the leaves dry up and wither. Spots also appear on sheath. Severely infected nursery and field appear as burnt. Black lesions appear on nodes girdling them. The affected nodes may break up and all the plant parts above the infected nodes may die (nodal blast). -

Castroagudín1, S.I. Moreira2, D.A.S. Pereira1,3, S.S. Moreira1, P.C. Brunner 3, J.L.N. Maciel 4, P.W. Crous5,6,7, B.A. McDonald3, E. Alves2, P.C. Ceresini1 Key words Abstract Pyricularia oryzae is a species complex that causes blast disease on more than 50 species of poaceous plants. Pyricularia oryzae has a worldwide distribution as a rice pathogen and in the last 30 years emerged as an cryptic species important wheat pathogen in southern Brazil. We conducted phylogenetic analyses using 10 housekeeping loci for host adaptation 128 isolates of P. oryzae sampled from sympatric populations of wheat, rice, and grasses growing in or near wheat phylogenetics fields. Phylogenetic analyses grouped the isolates into three major clades. Clade 1 comprised isolates associated systematics only with rice and corresponds to the previously described rice blast pathogen P. oryzae pathotype Oryza (PoO). Triticum aestivum Clade 2 comprised isolates associated almost exclusively with wheat and corresponds to the previously described wheat blast pathogen P. oryzae pathotype Triticum (PoT). Clade 3 contained isolates obtained from wheat as well as other Poaceae hosts. We found that Clade 3 is distinct from P. oryzae and represents a new species, Pyricu- laria graminis-tritici (Pgt). No morphological differences were observed among these species, but a distinctive pathogenicity spectrum was observed. Pgt and PoT were pathogenic and highly aggressive on Triticum aestivum (wheat), Hordeum vulgare (barley), Urochloa brizantha (signal grass), and Avena sativa (oats). -
Production Handbook Inside Cover Blank Louisiana Rice Production Handbook
Louisiana Rice Production Handbook Inside Cover blank Louisiana Rice Production Handbook Foreword Rice is one of the world’s most important cereal crops. Cereal crops are members of the grass family (Gramineae or Poaceae) grown for their edible starchy seeds. The term “cereal” is derived from the Greek goddess, Ceres or “giver of grain.” Rice and wheat are two of the most important cereal crops and together make up the majority of the world’s source of calories. They feed the world. In the United States rice is grown on approximately three million acres in two distinct regions, California and several southern states; Arkansas, Louisiana, Mississippi, Missouri and Texas. A small amount is also grown in Florida and South Carolina. Rice has been grown in Louisiana for over 300 years and today is one of the most important crops grown here. In 1987 the first Louisiana Rice Production Handbook was published with the intent of putting into one volume a comprehensive reference to all aspects of rice production in Louisiana. The handbook was revised in 1999 with extensive changes and again in 2009. The 2009 edition was so popular it became apparent supplies of printed copies would be exhausted well before the anticipated ten year revision anniversary would be reached. Rather than re-print that edition the authors decided to update it with new information, better and more photographs and the latest in research information. This edition retains the enduring information from the first, second and third editions, deletes dated product references, and adds the latest in rice production information. -

Crous, [email protected]; M.-H. Lebrun, [email protected] Abstract: Species of Pyricularia (magnaporthe-like sexual morphs) are responsible for major diseases on grasses. Pyricularia oryzae (sexual morph Magnaporthe oryzae) is responsible for the major disease of rice called rice blast disease, and foliar diseases of wheat and millet, while Pyricularia grisea (sexual morph Magnaporthe grisea) is responsible for foliar diseases of Digitaria. Magnaporthe salvinii, M. poae and M. rhizophila produce asexual spores that differ from those of Pyricularia sensu stricto that has pyriform, 2-septate conidia produced on conidiophores with sympodial proliferation. Magnaporthe salvinii was recently allocated to Nakataea, while M. poae and M. rhizophila were placed in Magnaporthiopsis. To clarify the taxonomic relationships among species that are magnaporthe- or pyricularia-like in morphology, we analysed phylogenetic relationships among isolates representing a wide range of host plants by using partial DNA sequences of multiple genes such as LSU, ITS, RPB1, actin and calmodulin. -

Genome Wide Analysis of the Transition to Pathogenic Lifestyles in Magnaporthales Fungi Received: 25 January 2018 Ning Zhang1,2, Guohong Cai3, Dana C
www.nature.com/scientificreports OPEN Genome wide analysis of the transition to pathogenic lifestyles in Magnaporthales fungi Received: 25 January 2018 Ning Zhang1,2, Guohong Cai3, Dana C.

Wisecaver12, Jie Zhu7 & Debashish Bhattacharya2 The rice blast fungus Pyricularia oryzae (syn. Magnaporthe oryzae, Magnaporthe grisea), a member of the order Magnaporthales in the class Sordariomycetes, is an important plant pathogen and a model species for studying pathogen infection and plant-fungal interaction. In this study, we generated genome sequence data from fve additional Magnaporthales fungi including non-pathogenic species, and performed comparative genome analysis of a total of 13 fungal species in the class Sordariomycetes to understand the evolutionary history of the Magnaporthales and of fungal pathogenesis. Our results suggest that the Magnaporthales diverged ca. 31 millon years ago from other Sordariomycetes, with the phytopathogenic blast clade diverging ca. 21 million years ago. Little evidence of inter-phylum horizontal gene transfer (HGT) was detected in Magnaporthales. In contrast, many genes underwent positive selection in this order and the majority of these sequences are clade-specifc. The blast clade genomes contain more secretome and avirulence efector genes, which likely play key roles in the interaction between Pyricularia species and their plant hosts. Finally, analysis of transposable elements (TE) showed difering proportions of TE classes among Magnaporthales genomes, suggesting that species-specifc patterns may hold clues to the history of host/environmental adaptation in these fungi. -

Abstract The distribution and diversity of RNA viruses in fungi is incompletely understood due to the often cryptic nature of mycoviral infections and the focused study of primarily pathogenic and/or economically important fungi. As most viruses that are known to infect fungi possess either single-stranded or double-stranded RNA genomes, transcriptomic data provides the opportunity to query for viruses in diverse fungal samples without any a priori knowledge of virus infection. Here we describe a systematic survey of all transcriptomic datasets from fungi belonging to the subphylum Pezizomycotina. -
Nutritional Characteristics of Hydrilla Verticillata and Its Effect on Two Biological Control Agents
Nutritional characteristics of Hydrilla verticillata and its effect on two biological control agents J.F. Shearer, M.J. Grodowitz and J.E. Freedman Summary A complex of abiotic and biotic factors is known to impact the establishment and success of biological control agents. Experiments using the ephydrid fly Hydrellia pakistanae Deonier have demonstrated that hydrilla, Hydrilla verticillata (L.f.) Royle, containing low protein content appears to impact larval development time and the number of eggs oviposited per female. Eggs per female were over twofold higher for larvae reared on hydrilla containing 2.4-fold more protein. Mean adult female fly weight peaked when emergence is low (i.e. low crowding) and leaf protein content is high. The hy- drilla biological control pathogen Mycoleptodiscus terrestris (Gerd.) Ostazeski also responds to plant nutritional condition. The nutritional status of hydrilla shoots affects M. terrestris vegetative growth, disease development and conidia and microsclerotia production. High protein content in shoot tissues was associated with a more than threefold increase in conidia production and maximum disease se- verity. In contrast, low protein content in shoot tissues stimulated a 3.7-fold increase in melanized mi- crosclerotia, reproductive structures that are more persistent in the environment than conidia. These studies suggest that the nutritional condition of target plants cannot be excluded as an important factor in efficacy of biological control agents. Both agents responded to favorable conditions by reproducing prolifically, which ultimately resulted in increased host damage. Keywords: Hydrellia pakistanae, Mycoleptodiscus terrestris, evaluation.
