<p>La marchitez y pudrición seca del cogollo del agave (<em>Agave tequilana</em> var. azul) son enfermedades de alto impacto económico para este cultivo. En este trabajo se planteó determinar la implicación de <em>Fusarium</em> spp. en ambas enfermedades bajo un enfoque regional. Se colectaron muestras de raíz y suelo en 40 plantaciones comerciales ubicadas en 13 municipios de Los Altos Jalisco, importante región de cultivo de agave azul en México. De cada plantación de colecta se estimó carga de inóculo mediante un índice de <em>Fusarium</em> obtenido de unidades formadoras de colonias (<em>Fusarium</em> vs hongos totales) y se analizó su relación con pH y materia orgánica. Se obtuvieron 109 aislados caracterizados morfológicamente como <em>Fusarium</em> spp. de los cuales se seleccionaron 25 para identificación molecular con ITS y EF-1a. La selección consideró sintomatología, caracteres macro y microscópicos y prevalencia de tipologías de colonia observadas <em>in vitro</em> en medios Komada, Sabouraud, SNA y CLA. Los caracteres culturales y morfológicos evaluados fueron: coloración micelial, tamaño, forma y septación de macro y microconidios, y longitud y número de fiálides. Se asociaron cinco especies con marchitez y/o pudrición seca ubicadas en tres complejos filogenéticos: <em>F. oxysporum</em> del complejo de especies <em>Fusarium oxysporum</em> (FOSC) con 56% (46.2% suelo y 66.7% raíz) de representatividad regional; <em>F. solani, F. falciforme</em> y <em>Fusarium</em> sp. del complejo <em>Fusarium solani</em> (FSSC) (40%); y <em>Fusarium</em> sp. del complejo <em>Fusarium fujikuroi</em> (FFSC) (4%). MO y pH tuvieron correlación inversamente proporcional con Índice de <em>Fusarium</em> (<em>r2</em> = 0.68-0.70). Se postula que la marchitez y pudrición seca del cogollo de agave azul constituyen un síndrome en el cual se asocian y especializan parasíticamente diversas especies de <em>Fusarium</em>. Se encontró un aislado de los tres complejos de <em>Fusarium</em> asociados específicamente a cada tipo de síntoma y la combinación de ellos. La mayoría se asociaron a marchitez con predominancia de<em> F. oxysporum. </em>  </p><p> </p>

Fungi mycotoxins can be a serious risk to health and lead to substantial economic loss. The environmental conditions of Saudi Arabia, with its mostly warm temperatures, are conducive to the growth of toxigenic fungi resulting in mycotoxin production in different food items. The current study elucidates the natural occurrence of toxigenic fungi and mycotoxin production in grains in Saudi Arabia. Samples of white rice and corn (yellow, red) grains were collected from different local markets and houses. Three fungal isolates were obtained from the corn and rice grains and examined using Potato Dextrose Agar (PDA) and Carnation Leaf Agar (CLA) media. Fusarium spp. were the most prominent fungi in yellow corn, red corn and white rice grains. Three isolated F. moniliforme strains were identified using molecular characterization of the trichothecene 3-O acetyltransferase (TRI101) toxin gene. The DNA genome of the three Fusarium moniliforme isolates (namely, F. moniliforme_1, F. moniliforme_2 and F. moniliforme_3, which correspond to isolates from yellow corn, red corn and white rice, respectively) were used as a template for PCR to amplify trichothecene 3-O acetyltransferase (TRI101). Partially sequenced fragments amplified using a specific primer set were used to confirm the identification of, and to evaluate the phylogenetic relationships among the three isolates as well as  to identify the corresponding antigenic determinants. The epitope prediction analysis demonstrated that there were four epitopes with scores equal to 1 in F. moniliforme_1, F. moniliforme_2 and F. moniliforme_3, respectively. Interestingly, there were great dissimilarities in the epitope sequences among the three isolates except in NSTPRACASEQEVS, STSSRADSSSLSTD and CTLCPRSLMASSVR. This indicates that the unique antigenic determinants predicted in the trichothecene 3-O acetyltransferase (TRI101) toxin gene could be used for designing a broad spectrum antibody for rapid detection of Fusarium spp. in foods.
