“…Furthermore, F. bubalinum and F. monophialidicum did not produce any sporodochia on carnation leaves, whereas F. incarnatum and F. tanahbumbuense produce abundant sporodochia on carnation leaves. Notes - Santos et al (2019) introduced the Latin binomial F. caatingaense to represent phylo-species FIESC 20, which formed a distinct fully supported clade (ML & MP-BS = 100 %, PP = 1.0) in this study. This species was shown to have a heterothallic mating system, producing typical gibberella-like perithecia exuding viable ascospores.…”

“…This species was shown to have a heterothallic mating system, producing typical gibberella-like perithecia exuding viable ascospores. This species is also characterised by the various shapes of aerial conidia (up to four) produced in culture (Santos et al 2019). Notes - Gerlach & Nirenberg (1982) studied isolate CBS 193.65 and considered it a good representative of F. camptoceras, providing illustrations that match the original description provided by Wollenweber & Reinking (1925), and drawings and description from the type isolate (R42; Wollenweber & Reinking 1925) later published in Reinking & Wollenweber (1927).…”

“…Wang et al (2019) resolved 33 phylo-species and introduced Latin binomials for nine: F. arcuatisporum (FIESC 7), F. citri (FIESC 29), F. guilinense (FIESC 21), F. hainanense (FIESC 26), F. humuli (FIESC 33), F. ipomoeae (FIESC 1), F. irregulare (FIESC 15), F. luffae (FIESC 18) and F. nanum (FIESC 25). Santos et al (2019) also resolved 30 phylo-species (FIESC 1-30) in their study on insect associated FIESC strains and were able to induce the sexual morphs of both FIESC 17 and FIESC 20, which they named F. pernambucanum and F. caatingaense, respectively.…”

“…The Fusarium incarnatum-equiseti species complex (FIESC) is a phylogenetically species-rich complex that includes over 30 recognised phylogenetic species (phylo-species) (O'Donnell et al 2009, 2010, Villani et al 2016, Santos et al 2019. The majority of these phylo-species are considered cryptic, making identification based solely on phenotypic characters problematic (Villani et al 2016).…”

The Fusarium incarnatum-equiseti species complex (FIESC) is a phylogenetically species-rich complex that includes over 30 cryptic phylogenetic species, making identification based on phenotypic characters problematic. Several established Fusarium species known to reside in the FIESC lack type material, further complicating the use of Latin binomials for this complex. To overcome this problem, an informal classification system based on a haplotype nomenclature was introduced to improve communication between researchers in various fields. However, some conflicts in the application of this nomenclature system have arisen. To date, 16 phylo-species in the FIESC have been provided with Latin binomials with approximately 18 FIESC phylo-species still lacking Latin binomials, the majority of which reside in the Incarnatum clade. The aim of this study is to introduce Latin binomials for the unnamed FIESC phylo-species based on phylogenetic inference supported by phenotypic characters. The three-gene (calmodulin, RNA polymerase II second largest subunit and translations elongation factor 1-alpha) phylogenetic inference resolved 47 lineages, of which 44 belonged to the FIESC. The F. camptoceras species complex (FCAMSC) is introduced here for three lineages that are distinct from the FIESC. Epitypes are designated for F. compactum, F. incarnatum and F. scirpi, and a neotype for F. camptoceras. Latin binomials are provided for 20 of these newly resolved phylo-species in the FIESC.

“…Observation and description of the reproductive structures were performed using a Nikon SMZ1000 optical microscope coupled to a digital camera. Morphological characteristics of conidia were studied based on the shape, the septation and the mean of dimensions (width and length) calculated from 30 measurements performed in the light microscope (Fourie et al, 2011;Santos et al, 2019).…”

The Causal Agent of Damping-off in Pinus patula (Schiede) and Pinus tecunumanii (Schwerdtf.)

et al. 2019

Damping-off is considered one of the most serious risks for production of Pinus seedlings due to the significant losses it can cause in forest nurseries. In Colombia there is little information about the etiology of this limiting disease. Different species of the genus Fusarium have been reported as causal agents, which makes the study of the pathogenicity of this genus relevant. In this study, strain 001F of Fusarium oxysporum was obtained from the diseased tissues of P. patula seedlings. The identity of the species was determined by sequencing the internal transcribed spacer (ITS) regions. Pathogenicity tests confirmed the ability of strain 001F to cause damping-off symptoms in P. patula and P. tecunumanii. Thus, F. oxysporum strain 001F represents a significant risk to produce tree species in Colombia and in other parts of the world.

Spatial pattern of genetic diversity in field populations of Fusarium incarnatum‐equiseti species complex

Fusarium is associated with a number of wilt, blight, scab, and rot diseases in a range of economically important staple food crops worldwide. An assessment of the genetic structure and population stratification of Fusarium incarnatum‐equiseti species complex (FIESC) pathogen populations is important to understand the evolutionary potential of such populations in adapting to environmental change. Based on intersimple sequence repeat polymerase chain reaction (ISSR‐PCR), it was found that the pathogen population was structured into three genetic clusters for which genetic differentiation was higher within than among populations. There was high intrapopulation genetic diversity for population 1 (94.63%) which consisted largely of isolates collected from North Trinidad. Populations 2 and 3 had a low level of admixture among the populations based on overall population differentiation. Population 1 accounted for the highest amount of genetic variation (95.82%) followed by populations 2 and 3. Population stratification was reflected in the dendrogram topology, which consisted of three main genetic clusters and which coincided with the outcome of Bayesian and PCoA analyses. The populations were isolated by distance, and Voronoi tessellations indicated physical or structural barriers to gene flow which contributed to restricted admixture between two of three populations. These findings suggest a high evolutionary potential for this FIESC pathogen population, the implications of which directly affect disease management strategies.
