an arbuscular mycorrhizal fungus and epichloe festucae var lolii reduce bipolaris sorokiniana Disease Incidence and improve perennial ryegrass growth
Mycorrhiza, 2018Co-Authors: Fang Li, Michael J Christensen, Yanzhong Li, Tingyu DuanAbstract:Leaf spot of perennial ryegrass (Lolium perenne) caused by Bipolaris sorokiniana is an important Disease in temperate regions of the world. We designed this experiment to test for the combined effects of the arbuscular mycorrhizal (AM) fungus Claroideoglomus etunicatum and the grass endophyte fungus Epichloe festucae var. lolii on growth and Disease occurrence in perennial ryegrass. The results show that C. etunicatum increased plant P uptake and total dry weight and that this beneficial effect was slightly enhanced when in association with the grass endophyte. The presence in plants of both the endophyte and B. sorokiniana decreased AM fungal colonization. Plants inoculated with B. sorokiniana showed the typical leaf spot symptoms 2 weeks after inoculation and the lowest Disease Incidence was with plants that were host to both C. etunicatum and E. festucae var. lolii. Plants with these two fungi had much higher activity of peroxidases (POD), superoxide dismutase (SOD) and catalase (CAT) and lower values of malondialdehyde (MDA) and hydrogen peroxide (H2O2). The AM fungus C. etunicatum and the grass endophyte fungus E. festucae var. lolii have the potential to promote perennial ryegrass growth and resistance to B. sorokiniana leaf spot.

Disease Incidence of charcoal rot (Macrophomina phaseolina) on soybean in north-western Argentina and genetic characteristics of the pathogen
'Informa UK Limited', 2018Co-Authors: Reznikov Sebastian, Mengistu Alemu, Vellicce, Gabriel Ricardo, Arias, Renee Silvia, Gonzalez Victoria, De Lisi Vicente, García, María Gabriela, Rocha, Carla Maria Lourdes, Pardo, Esteban Mariano, Castagnaro, Atilio PedroAbstract:Charcoal rot of soybean (Glycine max (L.) Merr.), caused by Macrophomina phaseolina (Tassi) Goid., is an economically important Disease worldwide. In recent years, charcoal rot has become a concern for farmers in north-western Argentina. The present work aimed to (1) evaluate Disease Incidence of charcoal rot; (2) assess morphological and genetic characteristics of M. phaseolina isolates from soybean and other hosts collected in north-western Argentina; and (3) compare genetic diversity between soybean isolates of M. phaseolina from Argentina and the USA. Incidence of charcoal rot evaluated in 11 locations during five growing seasons (2008–2012) was 1%, 1%, 1%, 5–10% and 90%, respectively, indicating a gradual increase over the cropping seasons. Cluster analysis by AFLP of Argentinean isolates exhibited one main group, with isolate Mp56 separated at a genetic distance of 0.70. Four main groups were identified using SSR markers at the same genetic distance, with Mp56 and Mp53 separated from them. There was no clear association between AFLP, SSR profiles, morphological characteristics or host of origin within isolates from Argentina. However, using principal coordinate analysis of SSRs, 22 isolates of M. phaseolina from soybean from north-western Argentina were clearly distinguished from 11 isolates previously collected from two states in the USA. Our results confirmed the increasing importance of charcoal rot in north-western Argentina and identified characteristics of isolates that may be useful for breeding for Disease resistance and developing integrated management programmes for charcoal rot in Argentina in the future.Fil: Reznikov, Sebastian.

Nos résultats confirment l’importance croissante de la pourriture noire dans le nord-ouest de l’Argentine. Ils ont permis de définir les caractéristiques des isolats qui pourraient être utiles en vue d’une sélection visant la résistance et l’élaboration d’un programme de gestion intégrée pour, dans l’avenir, combattre la pourriture noire en Argentine
