Última Caractérisation et diversité des mécanismes du syndrome de mortalité affectant les juvéniles de Crassostrea gigas ArchiMer Lucasson, Aude. nfectious diseases are very often explored using reductionist approaches, despite repeated evidence showing them to be strongly influenced by numerous interacting host and environmental factors. Many diseases with complex etiology therefore remain misunderstood. In this thesis, by developing a holistic approach to tackle the complexity of the interaction, (i) we deciphered the complex intra-host interactions underlying the Pacific oyster mortality syndrome affecting juveniles of Crassostrea gigas, the main oyster species exploited worldwide and (ii) we validated this mechanism in different infectious environments and oyster genotypes. Using ecologically realistic experimental infections combined with thorough molecular (metabarcoding, transcriptomics,...

Las variantes de maíz (Zea mays L.) nativas (criollos) preservadas por los agricultores a través de generaciones, constituyen más de 80% del área sembrada con maíz en México; la pudrición de mazorca por Fusarium spp. provoca pérdidas de hasta 30%. El estudio de las poblaciones de maíz y sus patógenos como patosistema tiene sentido, pues en la variación genética del maíz nativo se puede encontrar resistencia/tolerancia a enfermedades; el conocimiento de la estructura de las poblaciones de maíz y del patógeno de manera integral ayudaría a resolver el problema de pudrición, aumentar la producción de grano y conservar la diversidad del maíz. En 2010 se colectaron 56 poblaciones de maíz nativo con y sin síntomas de pudrición de mazorca en cinco estados en...

Alves,Edson Souza; Fonseca,Wéverson Lima; Silva,Luís Gustavo Chaves da; Lima,Joilson Silva; Cardoso,José Emilson. ABSTRACT Cashew gummosis is one of the main diseases of the cashew in the semi-arid region of the northeast and is characterised by a decline in the plants and a reduction in stand. Lasiodiplodia theobromae, the causal agent, is an endophytic fungus that eventually takes on pathogenic characteristics; however, the environmental conditions that cause this change in behaviour are still unknown. It is assumed that stress in the host caused by environmental changes stimulate pathogenicity. The aim of this study was to define the relationship between climate and geographical factors and the occurrence of gummosis. Rainfall data, maximum and minimum temperature, thermal amplitude, and the altitude of 14 micro-regions in the northeast were compared and classified...
