“…Fusarium graminearum s.s. appeared as the predominant species, followed by F. proliferatum , F. andiyazi , F. fujikuroi and F. thapsinum. Although all of these species have previously been present in sorghum in other parts of the world, our data indicate that F. graminearum s.s. is the main contaminant of sorghum, which differs from that reported in other studies where FFSC resulted in the most frequent contaminants [ 8 , 9 , 10 , 11 , 21 , 22 ]. This can be partially explained by the crop rotation system in Uruguay, where sorghum is generally planted after wheat or barley, so the prevalence of F. graminearum s.s could be due to inoculum carryover from the previous crop.…”

Grain mold and stalk rot are among the fungal diseases that cause significant losses in sorghum worldwide and are caused by different Fusarium spp. The presence of Fusarium species in sorghum grains causes yield losses and mycotoxin contamination, which represents a risk to consumers. In this study, Fusarium graminearum species complex (FGSC) had a high incidence, followed by Fusarium fujikuroi species complex (FFSC) and F. incarnatum-equiseti species complex. Within FFSC, F. proliferatum, F. andiyazi, F. fujikuroi, F. thapsinum, F. verticillioides and F. subglutinans were identified, and this was the first report of F. fujikuroi in sorghum. The most frequent toxins found in sorghum samples were deoxynivalenol (DON) and zearalenone (ZEN). The presence of fumonisins and nivalenol (NIV) was detected at low levels. This study adds new knowledge about the occurrence of Fusarium species and mycotoxins in sorghum grains. Furthermore, this is the first report in Uruguay on fungicide sensitivity for Fusarium isolates from sorghum, which constitutes an important starting point for defining management practices to minimize fungal infection and mycotoxin contamination.

“…The Fusarium fujikuroi species complex (FFSC) is usually associated with sorghum in different countries [ 3 , 8 , 9 , 10 , 11 , 12 ]. In addition, some species of this complex can produce fumonisins (FBs), a group of mycotoxins responsible for the contamination of sorghum grains [ 13 ].…”

“…A major limitation in sorghum production is stalk and root rot, which is mainly associated with a variety of soilborne fungi such as Fusarium species, Macrophomina phaseolina , Pythium species, and Colletotritichum graminicola [ 80 , 81 , 82 , 83 ]. These genera are also problematic in legume production [ 84 , 85 ].…”

Plant and Soil Core Mycobiomes in a Two-Year Sorghum–Legume Intercropping System of Underutilized Crops in South Africa

et al. 2022

Fungal communities form close beneficial (mutualists) or detrimental (pathogens) associations with their plant hosts. Their diversity and abundance can be affected by agricultural practices which include cropping systems such as rotations and intercropping. Despite the importance of cropping systems in increasing productivity, knowledge of the fungal mycobiome and the core inhabitants for under-utilised cereal and legume crops, particularly over a period, is still limited. The core mycobiomes in plant tissues and bulk soils of a cereal–legume intercrop were characterized over two years using high-throughput sequencing. The intercropping trial consisted of sorghum, Bambara groundnut, cowpea, dry bean, and soybean. A greater number of molecular operational taxonomic units (MOTUs) were found in plant tissues compared to those from the soils and between year one and year two. Principal coordinate analyses revealed that fungal communities for each year were relatively distinct, particularly for the soils. The core mycobiome was dominated by a Davidiellaceae sp. (Cladosporium), Didymellaceae sp. 1 (Phoma), Didymellaceae sp. 2 (Epicoccum), Fusarium sp. 2, Unidentified (Ascomycota), and Cryptococcus MOTUs that were present in all plant tissues and soils of year one and two. Other key MOTUs were only specific to a year, substrate, or crop. Although the mycobiome of sorghum were more distinct than the cores of the legumes, there were still MOTUs dominant across all of the crops. Characterization of this baseline core across two years provides insight into those fungi that are always present in these crops, and that could be utilized in improving crop performance and productivity.

“…1987 ). Since then, F. beomiforme has also been recovered from Thailand (from soil where previously sorghum had been cultivated; Mohamed Nor et al . 2019 ), though to date, F. beomiforme has not been reported to be pathogenic, and is probably a saprobe.…”

Seven Fusarium species complexes are treated, namely F. aywerte species complex (FASC) (two species), F. buharicum species complex (FBSC) (five species), F. burgessii species complex (FBURSC) (three species), F. camptoceras species complex (FCAMSC) (three species), F. chlamydosporum species complex (FCSC) (eight species), F. citricola species complex (FCCSC) (five species) and the F. concolor species complex (FCOSC) (four species). New species include Fusicolla elongata from soil (Zimbabwe), and Neocosmospora geoasparagicola from soil associated with Asparagus officinalis (Netherlands). New combinations include Neocosmospora akasia, N. awan, N. drepaniformis, N. duplosperma, N. geoasparagicola, N. mekan, N. papillata, N. variasi and N. warna. Newly validated taxa include Longinectria gen. nov., L. lagenoides, L. verticilliforme, Fusicolla gigas and Fusicolla guangxiensis. Furthermore, Fusarium rosicola is reduced to synonymy under N. brevis. Finally, the genome assemblies of Fusicolla betae (CBS 175.32), Microcera coccophila (CBS 310.34), Rectifusarium robinianum (CBS 430.91), Rugonectria rugulosa (CBS 126565), and Thelonectria blattea (CBS 952.68) are also announced here.
