Fusarium incarnatum-equiseti species complex associated with Brazilian rice: Phylogeny, morphology and toxigenic potential

A novel lineage in the Fusarium incarnatum‐equiseti species complex is one of the causal agents of fusarium rot on melon fruits in Northeast Brazil

“…FIESC species reported from plants were commonly isolated from cereals, such as wheat, barley, rice, oat, and maize, and from soybean (Amatulli et al, 2010;Maheshwar and Janardhana, 2010;Marín et al, 2012;Castellá and Cabañes, 2014;Villani et al, 2016Villani et al, , 2019Avila et al, 2019;Hartman et al, 2019). The reports in this study of F. sulawense and the new lineage are the first on melon fruits causing a postharvest disease.…”

“…FIESC 31-a was reported by Short et al (2011) from hospital sewage pipes. Avila et al (2019) suggested that the FCR R 10113 isolate (FIESC 31-a) should be considered as FIESC 4 lineage. However, the results obtained in the present study separated FIESC 31-a from FIESC 4, with 97% of bootstrap support and 0.99 of posterior probability supporting the separation of these two lineages.…”

“…Electropherograms were visually analysed in BioEdit (Hall, 1999) and the edited contig sequences were compared using BLAST in the GenBank database, National Center for Biotechnology Information (http://www.ncbi.nlm.nih.gov). Reference sequences of TEF1 and RPB2 from Fusarium species belonging to FIESC (O'Donnell et al ., 2009, 2018; Short et al ., 2011; Villani et al ., 2016; Avila et al ., 2019; Maryani et al ., 2019; Santos et al ., 2019; Wang et al ., 2019; Xia et al ., 2019), available at GenBank, were also included in the analyses.…”

“…Their phylogenies showed several phylogenetic species forming two sister clades, comprising a major clade named F. incarnatum‐equiseti species complex (FIESC; O'Donnell et al ., 2009). The FIESC has high genetic diversity, and currently there are 38 recognized lineages representing isolates from humans, animals, insects, hospital sewage pipes, cereals, soybean, wheat, maize, rice, tangerine leaves, and cashew and banana trees (O'Donnell et al ., 2009, 2012; Short et al ., 2011; Villani et al ., 2016, 2019; Avila et al ., 2019; Hartman et al ., 2019; Maryani et al ., 2019; Santos et al ., 2019; Wang et al ., 2019; Xia et al ., 2019).…”

Fusarium incarnatum is associated with postharvest fruit rot of muskmelon (Cucumis melo)

“…Fusarium incarnatum is capable of producing mycotoxins such as fuminosin (Naiker & Odhav, ), deoxynivalenol and zearalenone (Avila et al, ). These chemicals induce apoptosis at a cellular level (Abid‐Essefi et al, ; Li et al, ) and are responsible for certain clinical symptoms such as vomiting and diarrhoea in humans (Liao, Chiueh, & Shih, ).…”
