Background Early leaf spot disease, caused by Cercospora arachidicola, is a devastating peanut disease that has severely impacted peanut production and quality. Chemical fungicides pollute the environment; however, Bacillus bacteria can be used as an environmentally friendly alternative to chemical fungicides. To understand the novel bacterial strain and unravel its molecular mechanism, De novo whole-genome sequencing emerges as a rapid and efficient omics approach. Results In the current study, we identified an antagonistic strain, Bacillus amyloliquefaciens TA-1. In-vitro assay showed that the TA-1 strain was a strong antagonist against C. arachidicola, with an inhibition zone of 88.9 mm. In a greenhouse assay, results showed that the TA-1 strain had a significant biocontrol effect of 95% on peanut early leaf spot disease. De novo whole-genome sequencing analysis, shows that strain TA-1 has a single circular chromosome with 4172 protein-coding genes and a 45.91% guanine and cytosine (GC) content. Gene function was annotated using non-redundant proteins from the National Center for Biotechnology Information (NCBI), Swiss-Prot, the Kyoto Encyclopedia of Genes and Genomes (KEGG), clusters of orthologous groups of proteins, gene ontology, pathogen�host interactions, and carbohydrate-active enZYmes. antiSMASH analysis predicted that strain TA-1 can produce the secondary metabolites siderophore, tailcyclized peptide, myxochelin, bacillibactin, paenibactin, myxochelin, griseobactin, benarthin, tailcyclized, and samylocyclicin. Conclusion The strain TA-1 had a significant biological control effect against peanut early leaf spot disease in-vitro and in greenhouse assays. Whole genome analysis revealed that, TA-1 strain belongs to B. amyloliquefaciens and could produce the antifungal secondary metabolites.
... There is no doubt that Cercosporoid fungi are one of the most significant groups of plant pathogenic fungi that cause leaf spots. A wide range of plants (including cultivated plants on almost every continent) are affected by these diseases, including dicots, monocots, gymnosperms, and ferns [4,5]. To control fungus pathogens, fungicides have been proven to be the most effective; however, these chemicals cause environmental pollution and alarming human health concerns [6,7]. ...

A novel Bacillus amyloliquefaciens BAM strain, with novel fermentation nutrient mediums and compositions, could produce potent antifungal secondary metabolites, as the existing strains face resistance from fungus pathogens. In the current study, we introduced two novel nutrient mediums for the fermentation process, semolina and peanut root extract, as carbon and nitrogen sources in order to maximize the antifungal effects of B. amyloliquefaciens against Cercaspora arachidichola to control early leaf spot disease in peanuts. Based on a single-factor test and the central composite design of response surface methodology, the optimum fermentation medium for Bacillus amyloliquefaciens antagonistic substance was determined, containing 15 gm/L of semolina flour, 12.5 gm/L of beef extract, and 0.5 gm/L of magnesium sulfate, which inhibited the fungal growth by 91%. In vitro, antagonistic activity showed that the fermentation broth of B. amyloliquefaciens BAM with the optimized medium formulation had an inhibition rate of (92.62 ± 2.07)% on the growth of C. arachidichola. Disease control effects in pot experiments show that the pre-infection spray of B. amyloliquefaciens BAM broth had significant efficiency of (92.00 ± 3.79)% in comparison to post-infection spray. B. amyloliquefaciens BAM broth significantly promoted peanut plant growth and physiological parameters and reduced the biotic stress of C. archidechola. Studies revealed that B. amyloliquefaciens BAM with a novel fermentation formulation could be an ideal biocontrol and biofertilizer agent and help in early disease management of early leaf spots in peanuts.
... Cercospora is the largest genus of asexual fungi which is commonly referred as cercosporoid fungi belonging to Mycosphaerellaceae (Mycosphaerellales, Ascomycota). It represents a large group of leaf spotting, plant pathogenic species, causing diseases on a wide range of hosts (Crous & Braun 2003;Braun & al. 2013Braun & al. , 2016. The distoseptate nature of conidia is exhibited by Distocercospora N. Pons & B. Sutton and Distocercosporaster Videira & al. within the cercosporoid complex (Braun & al. 2014, Videira & al. 2017. ...

Blackberry (Rubus L. subgenus Rubus Watson) is a deciduous berry crop that is the fourth most economically important berry crop, and its production is expanding in the southeastern United States. However, since most commercially available cultivars were bred under temperate conditions, they are not always well adapted and could be threatened by new pathogen populations inhabiting subtropical areas. In 2017, plants showing purple or brown leaf spots and angular-to-irregular lesions on both leaf surfaces, with clusters of black conidiophores at the center, were observed in a field trial at the University of Florida’s Gulf Coast Research and Education Center (UF/GCREC) in Wimauma, FL. A fungus resembling Cercospora/Pseudocercospora was isolated from the lesions. The ribosomal DNA internal transcribed spacers (ITS), the translation elongation factor 1-alpha (EF-1α), and the actin (ACT) genes were amplified and sequenced. Based on the phylogenetic analysis, the closest related species was Pseudocercospora pancratii. Pathogenicity assays and subsequent re-isolation confirmed that this species is the causal agent of the disease. Among eight cultivars screened, no complete resistance was found. However, ‘Osage’ was the least susceptible, and ‘Kiowa’ the most susceptible. This study is the first report of P. pancratii causing leaf spots on blackberry worldwide, and it may help shape future research into disease epidemiology and management for a crop that is rapidly expanding but has very limited disease information currently available for Florida growers.
... leaf-spotting fungi with a worldwide distribution, causing numerous economically significant diseases of agricultural crops (Albu et al., 2016;Crous et al., 2006Crous et al., , 2013Groenewald et al., 2013;Guillin et al., 2017;Vaghefi et al., 2019). Taxonomy and identification of the cercosporoid fungi has, in the past, mainly relied on host range and morphological characters (Crous & Braun, 2003), but this approach was problematic due to the limited number of morphological features in species resolution (Braun et al., , 2016Crous et al., 2013;Groenewald et al., 2013). The emergence of molecular phylogenetic methods and their application to the taxonomy of cercosporoid fungi has led to a better understanding of species identification in this group of fungi (Bakhshi et al., 2014(Bakhshi et al., , 2015(Bakhshi et al., , 2018Crous et al., 2013;Groenewald et al., 2013;Guatmosim et al., 2017;Nguanhom et al., 2015). ...

In recent years, common bean (Phaseolus vulgaris) and cowpea (Vigna unguiculata) plants in the north of Iran exhibit symptoms resembling Cercospora leaf spot (CLS) disease. This study was initiated to elucidate the taxonomy and pathogenicity of cercosporoid taxa associated with leaf spot diseases of these two legume crops in Iran. A total of 138 samples with CLS symptoms were collected from cultivated bean species in the north of Iran and subjected to microscopic examination, resulting in a total of 98 Cercospora and 59 Pseudocercospora samples. A six‐locus phylogenetic analysis (ITS, actA, tef1, gapdh, his3 and cmdA) coupled with morphology of 42 representative isolates revealed that several cercosporoid fungi occur on common bean and cowpea in Iran. Five Cercospora species including C. iranica, C. cf. flagellaris, Cercospora sp. G, Cercospora sp. T, and C. vignigena, and two Pseudocercospora species including P. griseola f. griseola and P. cf. cruenta were found associated with legume crops in Iran; of these, C. cf. flagellaris was the dominant species, occurring on both common bean and cowpea. Pathogenicity tests confirmed that all seven species could infect leaves of common bean and/or cowpea. This is the first report of C. iranica, Cercospora sp. G and Cercospora sp. T associated with common bean and/or cowpea in the world. In addition, C. vignigena is recorded for the first time in Iran. Results achieved in this study will assist the management strategies of the CLS disease of common bean and cowpea.

Phytopathogenic cercosporoid fungi have been investigated comprehensively due to their important role in causing plant diseases. A significant amount of research has been focused on the biology, morphology, systematics, and taxonomy of this group, with less of a focus on molecular or biochemical issues. Early and extensive research on these fungi focused on taxonomy and their classification based on in vivo features. Lately, investigations have mainly addressed a combination of characteristics such as morphological traits, host specificity, and molecular analyses initiated at the end of the 20th century. Some species that are important from an economic point of view have been more intensively investigated by means of genetic and biochemical methods to better understand the pathogenesis processes. Cercosporin, a photoactivated toxin playing an important role in Cercospora diseases, has been extensively studied. Understanding cercosporin toxicity in relation to reactive oxygen species (ROS) production facilitated the discovery and regulation of the cercosporin biosynthesis pathway, including the gene cluster encoding pathway enzymes. Furthermore, these fungi may be a source of other biotechnologically important compounds, e.g., industrially relevant enzymes. This paper reviews methods and important results of investigations of this group of fungi addressed at different levels over the years.

Cercosporoid fungi include a large number of mostly plant pathogenic fungi with a wide geographic distribution, being usually associated with leaf spots on a broad range of plant hosts. Here we initiate a series of studies on Chinese cercosporoid fungi, focussing on the identification of some common, rare and new plant diseases caused by these leaf-spotting ascomycetes. The aim of the series is to resolve the taxonomy and DNA phylogeny of this important group of phytopathogens in China. In this study, nine isolates of cercosporoid fungi were collected from five host species. Partial nucleotide sequence data of four gene loci (ITS, LSU, TUB and tef1-α rDNA) were generated for all isolates. Based on morphological characters in vivo and in vitro and phylogenetic data, a new species, Pseudocercospora pauciseptata (on living leaves of Pyracantha fortuneana), is introduced including a detailed description, illustration and comparison with similar species. In addition, Passalora circumscissa, Pseudocercospora cercidis-chinensis, P. lindericola, and P. prunicola are described, illustrated and phylogenetically characterized. Cerasus pseudocerasus represents a new host record for Passalora circumscissa in China, while Lindera reflexa is a new host for P. lindericola.
