Talaromyces minioluteus: New Postharvest Fungal Pathogen in Serbia

Abstract

Talaromyces minioluteus is one of the important species of genus Talaromyces, which has cosmopolitan distribution and is encountered on a wide range of different habitats. This species has not been considered as an important plant pathogen, even though it has been isolated from various plant hosts. Fruits and vegetables with Penicillium-like mold symptoms were collected from 2015 to 2017 from markets in Serbia. Isolates originating from quince, tomato, and orange fruits, onion bulbs, and potato tubers were identified and characterized on a morphological, physiological, and molecular level. Morphological and physiological examination included observing micromorphology, testing growth on six different media and at five different temperatures, and production of three enzymes. Molecular identification and characterization were performed using four molecular markers: internal transcribed spacer, β-tubulin, calmodulin, and DNA-dependent RNA polymerase II second largest subunit. The results of morphological and molecular analyses were in agreement, and they proved that the obtained isolates are T. minioluteus. In the pathogenicity assay, T. minioluteus was confirmed as a pathogen of all species tested with the exception of potato tubers. This is the first report of T. minioluteus as a postharvest plant pathogen on quince, tomato, and orange fruit and onion bulbs. Also, this is the first record of T. minioluteus in Serbia.

“…On the other hand, phytopathogenic fungi identified in this study include Curvularia lunata (Liu et al 2010 ), Phaeosphaeriopsis sp. (Golzar and Wang 2012 ; Thambugala et al 2014 ), Talaromyces minioluteus (Stošić et al 2019 ), P. noxium (Ann et al 2002 ; Sahashi et al 2014 ; Chung et al 2015 ), and Plectosphaerella cucumerina (Carlucci et al 2012 ; Li et al 2017 ).…”

Two Novel Species of Talaromyces Discovered in a Karst Cave in the Satun UNESCO Global Geopark of Southern Thailand

“…phuphaphetensis and T. satunensis from other species in the section. Although the RPB2 gene is formally accepted as a potential molecular locus for identifying Talaromyces species, it is often difficult to amplify the targeted DNA region [ 23 , 24 , 25 ]. Unfortunately, this study did not obtain RPB2 sequence data from T .…”

Microbiome Status of Cider-Apples, from Orchard to Processing, with a Special Focus on Penicillium expansum Occurrence and Patulin Contamination

“…The Cladiosporium genera is a post-harvest pathogen and is known to cause core browning and moldy core in apples [51]. However, antagonistic Cladosporium isolates were used as biocontrol agents to control apple scab caused by Venturia inaequalis in orchards [52]. Furthermore, P. expansum was not part of the most abundant taxa in the orchard, even though it was significantly found by qPCR on the surface of the apples.…”
