“…The SNA, PDA and Mathur media did not differ, but the Mathur medium promoted superior sporulation (Table 1). For Colletotrichum gloeosporioides, the Mathur medium was also able to provide greater sporulation when compared to other means (Lopez & Lucas, 2010).…”

Casuarina (Casuarina equisetifolia L.) is a species used like wind break, in streets ornamentation, soils conservation and dunes fixation. The main form of propagation of this species is by seeds, although, in nursery, the fungus Fusarium lacertarum have been cause damping-off in seedlings. Thus, the objective of this work was to characterize morphologically, physiologically and molecularly the pathogen. To molecular characterization, pure colonies were cultivated in PDA and LCA culture media, and for physiological characterization, colonies were cultivated in PDA, SNA, Mathur and V8 culture media. The genomic segment most appropriated to identify this species was the tef1-α. The causal agent of damping-off in Casuarina equisetifolia seedlings was confirmed like F. lacertarum, and the most efficient genomic region to identification is tef1-α. The best incubation condition to conidia production of F. lacertarum was in Mathur medium and the largest daily average growth was in SNA medium. The morphological characteristics are equivalent to the characterization of F. incarnatum-equiseti species complex isolated. Key words: ITS; nursery; phytopathogens; tef1-αCaracterização morfofisiológica e molecular de Fusarium lacertarum agente causal de tombamento em Casuarina equisetifolia RESUMO: A casuarina (Casuarina equisetifolia L.) é uma espécie utilizada como quebra-ventos, na ornamentação de ruas, conservação de solos e fixação de dunas. Sua principal forma de propagação é seminal, entretanto, em viveiros, o fungo Fusarium lacertarum tem causado tombamento em plântulas. Dessa forma, o objetivo deste trabalho foi caracterizar morfofisiológica e molecularmente o patógeno. Para a caracterização molecular, colônias puras foram cultivadas nos meios de cultura BDA e FCA, e para caracterização fisiológica, colônias foram cultivadas nos meios BDA, SNA, Mathur e V8. O segmento genômico mais apropriado para identificação da espécie foi o tef1-α. O agente causal de tomabamento em plântulas de Casuarina equisetifolia foi confirmando como F. lacertarum, sendo a região genômica mais eficiente para identificação a tef1-α. A melhor condição de incubação visando à produção de conídios de F. lacertarum foi em meio Mathur e o maior crescimento médio diário foi em meio SNA. As características morfológicas condizem com a caracterização de isolados do complexo de espécies F. incarnatumequiseti.

“…Furthermore, the wide host range associated with the causal agent makes the disease management a challenge (Abang et al, 2002). For example , Lopez & Lucas et al (2010) verified that C. gloeosporioides isolated from different plant hosts (avocado, mangabeira, passion fruit and acerola) are also pathogenic to cashew tree. This served as a clear indication that cultures of C. gloeosporioides from different hosts are a source of inoculum for avocado, therefore pose a challenge when it comes to control the disease in avocado where the alternate hosts are within the vicinity (Sideney & Dirlane, 2014).…”

“…The causal agent, C. gloeosporioides , is a common pathogen of other tropical fruit plants ( Figueiredo et al, 2012 ), highly variable in cultural and morphological characters, and in pathogenicity ( Freire and Cardoso, 2003 ). The pathogen can infect leaves, twigs, inflorescences, young apples and fruits, and symptoms include sunken subcircular or angular lesions that produce erumpent, mucilaginous, orange spore masses in favorable environments ( Lopez and Lucas, 2010 ). In severe cases, leaves and fruitlets become totally blighted and drop ( Freire et al, 2002 ).…”

“…Other phenomena, such as animal and anthropogenic dispersal, are likely to have significantly contributed, mostly due to agricultural practices and through introduction of infected plant materials. Moreover, the evidence for anthracnose cross-infection in cashew from other susceptible plants cultivated in close proximity under mixed cropping systems ( Lopez and Lucas, 2010 ; Lakshmi et al, 2011 ), calls for prudence and concern in managing disease control for cashew production.…”

Tracking cashew economically important diseases in the West African region using metagenomics

During the last decades, agricultural land-uses in West Africa were marked by dramatic shifts in the coverage of individual crops. Nowadays, cashew (Anacardium occidentale L.) is one of the most export-oriented horticulture crops, notably in Guinea-Bissau. Relying heavily on agriculture to increase their income, developing countries have been following a strong trend of moving on from traditional farming systems toward commercial production. Emerging infectious diseases, driven either by adaptation to local conditions or inadvertent importation of plant pathogens, are able to cause tremendous cashew production losses, with economic and social impact of which, in developing countries is often underestimated. Presently, plant genomics with metagenomics as an emergent tool, presents an enormous potential to better characterize diseases by providing extensive knowledge on plant pathogens at a large scale. In this perspective, we address metagenomics as a promising genomic tool to identify cashew fungal associated diseases as well as to discriminate the causal pathogens, aiming at obtaining tools to help design effective strategies for disease control and thus promote the sustainable production of cashew in West African Region.
