Morphological and Molecular Characterization of Fusarium Spp. Pathogenic to Ilex Paraguariensis

Abstract: MORPHOLOGICAL AND MOLECULAR CHARACTERIZATION OF Fusarium spp. PATHOGENIC TO Ilex Paraguariensis MEZZOMO, R.; ROLIM, J. M.; POLETTO, T.; ROSENTHAL, V. C.; SAVIAN, L. G.; REINIGER, L. R. S.; MUNIZ , M. F. B.Morphological and molecular characterization of Fusarium spp. pathogenic to Ilex Paraguariensis. CERNE, v. 24, n. 3, p. 209-218, 2018. HIGHLIGHTSDue to the low initial costs and ease of employment of agrosilvopastoral systems, the cultivation of yerba-mate constitutes an alternative for small properties in th… Show more

“…Other fungi showed varying results in the effect in the seeds of the Cuscuta and Ocimum. The reason for the difference in the pathogenetic ability of isolates may be due to the genetic heterogeneity between isolates and individuals of the same species, especially that they were isolated from different plants and regions, or the difference in the amount of secondary metabolic compounds secreted by them, such as their ability to secrete a number of enzymes that decompose the host cell walls that help to penetrate the host, including enzymes (Chitinase, Cellulose, Protease and polygalcturinase) enzymes play the main role in parasitizing living cells, which leads to rotting of seeds and preventing them from germinating and affecting the embryo because the infection of the embryo is the main reason for reducing the percentage In addition ,there is a family specialization between the pathogen and the host (28,8,24,29,30). It also has the ability to produce mycotoxins that kill seed embryos, which have a role in disease events by inhibiting the work of enzymes and the permeability of cell membranes and acting as an antidote that leads to a lack of plant growth factors (31,32,33) Table 4.…”

“…The experiment was conducted at the "Elocy Minussi" Phytopathology Laboratory of the Center of Rural Sciences of the Federal University of Santa Maria, Santa Maria, Rio Grande do Sul state (RS), Brazil. For the molecular characterization and the VCG test, a Fusarium oxysporum (I6AR2) and six other isolates from Fusarium solani (I1AR1, I8AR1, M3AR2, M4, M5AR2 and M7C1) pathogenic to mate, as described by Mezzomo et al (2018), collected in RS state, and deposited in the mycology collections of the same laboratory, where they remain stored in refrigeration in Eppendorff tubes, containing saline solution 0.85% NaCl (Table 1).…”

“…Os autores concluíram que o melhor crescimento, desenvolvimento e maior resistência da erva-mate ocorreram com os maiores níveis de sombreamento. Mezzomo et al (2018b) realizaram a caracterização morfofisiológica e a identificação molecular de isolados patogênicos de Fusarium spp. As amostras de raízes e as mudas foram obtidas de ervais localizados nos municípios de Anta Gorda, Arvorezinha, Putinga, Ilópolis e Machadinho, no Rio Grande do Sul.…”

“…Os autores identificaram sete isolados como patogênicos, e as espécies F. solani e F. oxysporum como as principais causadoras da podridão-de-raízes nos ervais do Rio Grande do Sul. Os resultados obtidos por Mezzomo et al (2018b) et al (2018), esta espécie teve o seu primeiro relato em 2018, com mortalidade superior à 5% dos ervais avaliados em São Mateus do Sul e Arvorezinha.…”
