Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera the terminal fusarioid clade of family Nectriaceae. Thus, an alternate hypothesis, namely a very broad concept genus Fusarium was proposed. In doing so, however, significant body data supports Nectriaceae based on morphology, biology, and phylogeny is disregarded. A DNA 19 orthologous protein-coding genes presented to support at F1 node Here, we demonstrate re-analyses this dataset show all F3 represents sensu stricto as defined by F. sambucinum (sexual morph synonym Gibberella pulicaris). The backbone resolved concatenated alignment, but only six fully node, representing circumscription Fusarium. Furthermore, re-analysis revealed topologies different phylogenetic algorithms, highlighting deep divergence unresolved placement various lineages proposed members Species s. str. characterised sexual morphs, asexual morphs with thin- or thick-walled macroconidia variously shaped apical basal cells, trichothecene mycotoxin production, which separates them from other genera.

Genetic and Genomic Tools in Breeding for Resistance to Fusarium Stalk Rot in Maize (Zea mays L.)

Plants, Год журнала: 2025, Номер 14(5), С. 819 - 819

Опубликована: Март 5, 2025

Maize (Zea mays L.) is the world's most productive cereal crop, yet it threatened by several diseases. Among them, Fusarium stalk rot (FSR) causes an average global yield loss of 4.5%. The mycotoxins deoxynivalenol, zearalenone, fumonisins, and moniliformin persist in grain silage after harvest pose a risk to human animal health. This review describes lifestyle fungal pathogens that cause FSR, studies how optimize resistance evaluation, identifies quantitative trait loci (QTLs) candidate genes (CGs), and, finally, considers methods for selecting FSR resistance, especially through genomic selection. To screen maize genotypes artificial inoculation have been employed studies, including toothpick insertion, ball-bearing pellets, root infection, oat kernel method. However, these limitations effectively inducing disease infection. Needle injection inoculum into stem recommended, when combined with or percentage scale because phenotypes populations resistance. Nine larger (≥150 progenies) investigated genetic architecture inheritance clearly quantitative. Four major QTLs minor are reported confer pathogens, few CGs identified. Genomic selection recommended as effective method developing routinely FSR-resistant maize, but only two explored this area. An omics analysis (proteomics, transcriptomics, metabolomics) expression should validate their role use might accelerate

Three new species of Fusarium (Nectriaceae, Hypocreales) isolated from Eastern Cape dairy pastures in South Africa

MycoKeys, Год журнала: 2025, Номер 115, С. 241 - 271

Опубликована: Март 20, 2025

A survey of the fungal diversity associated with mixed pastures from Eastern Cape dairy farms in South Africa led to isolation 155 Fusarium strains that belong incarnatum-equiseti species complex (FIESC). Using single and multigene phylogenies based on partial sequences translation elongation factor 1-alpha ( TEF ), calmodulin CaM RNA polymerase second largest subunit RPB2 ) genes, we identified 11 species. They included F. brevicaudatum , clavus coffeatum croceum goeppertmayerae heslopiae five were found be new. Based morphological phylogenetic data, three new are formally described here as cumulatum mariecurieae pascuum . We also provided a description for authors who named this did not include one. have chosen describe remaining species, our cultures lack proper structure development. This study shows harbour diverse range highlights need further studies into their potential impact animal health.

Morphological characterization, pathogenicity screening, and molecular identification of Fusarium spp. isolates causing post-flowering stalk rot in maize

Post flowering stalk rot (PFSR) of maize caused by the Fusarium species complex is a serious threat to production worldwide. The identification causing PFSR based on morphology traditionally relies small set phenomic characteristics with only minor morphological variations among distinct species. Seventy-one isolates were collected from 40 sites in five agro-climatic zones India assess diversity spp. associated crops showing symptoms field. To investigate pathogenicity sixty toothpick inoculated between first and second node at 55 days after sowing during tassel formation stage crop Kharif (Rainy season), Rabi (Winter season) season field trials.

Bats represent the second largest mammal group, with over 1400 known species dispersed across six continents.Bats are unique in many ways.Notably, their incredible longevity, a life span of up to ten times longer than what might be expected from body size and ability tolerate viruses without displaying any symptoms, means they provide an area particular importance disease risk perspective.In addition, warm, humid environments which bats occur ideal habitats for fungi grow, potentially carry various
