Hospedeiros alternativos de Acidovorax avenae subsp. citrulli

Abstract: pesquisa RESUMOUma das principais doenças que afeta o meloeiro é a manchaaquosa, causada pela bactéria Acidovorax avenae subsp. citrulli (Aac). Visando conhecer hospedeiros alternativos de Aac, plantas no estágio de primeiras folhas definitivas, de várias espécies/cultivares, incluindo cucurbitáceas, solanáceas, gramíneas, leguminosas e caricáceas, foram inoculadas pela atomização da parte aérea com suspensão dos isolados Aac 1.49 e Aac 12.13, oriundos de melão e melancia, respectivamente. A suscetibilidade da… Show more

“…It is possible that A. citrulli is a better blossom colonizer compared with X. euvesicatoria, and even blossoms of incompatible hosts like pepper ('Aristotle') can be colonized, leading to infestation of nonhost seed. Although previous studies showed compatible interactions of A. citrulli with pepper and other solanaceous hosts such as eggplant and tomato (1,22), strains used in this study produced hypersensitive reactions upon inoculation in pepper leaves ('Aristotle'). This indicated that A. citrulli strains used in this study were incompatible with the pepper cultivar used.…”

“…A comprovação da habilidade da bactéria sobreviver epifiticamente no mínimo por 60 dias nas raízes e na rizosfera de meloeiro, reforça a importância da aplicação de algumas medidas de controle, tais como: erradicar plantas voluntárias (Dias et al, 1998); destruir restos de culturas, principalmente em campos com plantas infectadas (O'Brien & Martin, 1999); eliminar outras hospedeiras alternativas (Nascimento et al, 2004), nas quais a bactéria, provavelmente, também sobrevive no rizoplano e rizosfera, além do filoplano.…”

“…citrulli sobrevive durante a entressafra em restos de cultura, em hospedeiros silvestres e cultivados, em plântulas voluntárias Latin & Hopkins, 1995;Santos & Viana, 2000;Nascimento et al, 2004), em sementes (Latin & Hopkins, 1995;Santos & Viana, 2000) e no solo por algumas semanas (Isakeit, 1999). Inexistem dados sobre a sobrevivência epifítica e endofítica dessa bactéria nas folhas e raízes de meloeiro, bem como sobre sua sobrevivência na rizosfera.…”

“…This bacterium has about 450 host species, belonging to over 54 botanical families (Wicker et al, 2007;Garcia et al, 2013), especially species of the Solanaceae family (Hayward, 1991). Acidovorax citrulli is the causal agent of bacterial fruit blotch, a disease that leads to decay fruit and often occurs in plants of Cucurbitaceae family (Burdman & Walcott, 2012), especially melon (Cucumis melo), watermelon (Citrullus lanatus) (Oliveira et al, 2007) and pumpkin (Cucurbita maxima) (Nascimento et al, 2004).…”
