Cunninghamella clavata from Brazil: a new record for the western hemisphere

Abstract

During a survey of Mucorales in Brejo dos Cavalos (a fragment of an Upland Atlantic Forest within the semi-arid region of Northeast Brazil) a specimen of Cunninghamella clavata was isolated from soil samples. A detailed description of the specimen and a phylogenetic analysis of its relationship with other Cunninghamella species are presented. An identification key for Cunninghamella taxa reported from Brazil is also provided.

Isolation and Characterization of Three Unrecorded Zygomycete Fungi in Korea: Cunninghamella bertholletiae, Cunninghamella echinulata, and Cunninghamella elegans

“…The genus Cunninghamella (Cunninghamellaceae, Mucorales) was established in 1903 by Matruchot, and is comprised of species characterized by the formation of the pedicellate and unispored sporangia on the surface of the entire vesicle [ 5 ]. There are 14 accepted species in this genus [ 6 7 8 ]. Cunninghamella species are often found in soil, stored grains, and other organic substrates [ 3 7 8 9 10 ].…”

“…Cunninghamella clavata, ocasionó una pudrición blanda en inflorescencias masculinas (Tabla 1), sobre la cual se desarrolló un micelio blanco de forma circular (Figura 2), que creció de manera uniforme hasta cubrir por completo a las inflorescencias, a la fecha este hongo no ha sido reportado como fitopatógeno, por lo que no se ha reportado una asociación de C. clavata con inflorescencias de yaca, por lo tanto, se considera que es la primera vez que se reporta como patogénico para las inflorescencias masculinas de yaca en Nayarit, México. En Brasil ha sido aislado a partir de muestras de suelo semiáridos sin tener más información (Alves et al, 2017). El género Cunninghamella sp., incluye especies de importancia médica como C. bertholletiae, la cual ocasiona sinusitis, zigomicosis endobronquial y pulmonar en pacientes con un sistema inmunológico débil (cáncer y diabetes mellitus, en procesos biotecnológicos), C. bainieri metaboliza xenobióticos, compuestos aromáticos y fármacos y C. elegans oxida los hidrocarburos aromáticos policíclicos (PAHs), petróleo y degrada el fluoranteno en un PAHs (Shiosaki et al, 2001).…”

“…Cunninghamella clavata, caused a soft rot in male inflorescences (Table 1), over which the circular white mycelium was developed (Figure 2), which grew evenly until entirely covering the inflorescences; to this day, this fungus has not been reported as a phytopathogen, which is why a relation between C. clavata and jackfruit inflorescences has not been reported, therefore, it is the first time it is reported as pathogenic for the male inflorescences of jackfruit in Nayarit, Mexico. In Brazil, it has been isolated from samples in semiarid soils without having more data (Alves et al, 2017) (Shiosaki et al, 2001).…”

Isomucor trufemiae J.I. de Souza, Pires-Zottarelli & Harakava (Mucorales, Mucoromycota): the second report worldwide and first from soil in northeastern Brazil

“…These characteristics reflect directly on the local vegetation, with semideciduous forests being predominant in this ecosystem (De Queiroz et al 2017). In Brazil, 47 Montane Atlantic Forest areas are known in the states of Ceará, Paraíba, Pernambuco and Rio Grande do Norte (Tabarelli and Santos 2004), and studies have pointed out that Montane Atlantic Forest areas of Pernambuco are havens for mucoralean fungi including newly proposed taxa (Alves et al 2017;Crous et al 2018;Lima et al 2018a;Crous et al 2019;Lima et al 2020). However, the knowledge of the genera Isomucor J.I Souza, Pires-Zottar.…”
