“…belongs to the A, D, E and F mating populations (Lim et al, 2001). Consistent with the present results, various population types were identified in the sorghum isolates from Brazil (A) and Korea (populations A, D, and F) (Rahjoo et al, 2008;Summerell et al, 1998). According to Lim et al (2001), a high frequency of hermaphrodites can be detected in the F population of the MAT-1 mating type (Rahjoo et al, 2008).…”

Fusarium verticillioides and Fusarium proliferatum cause a wide range of maize diseases. These fungi produce dangerous mycotoxins, such as fumonisin B1, which are important threats to humans and animals. Given this predicament, the present study aimed to identify the fungi both molecular-morphologically and also investigate the pathogenicity variation and mating type of 41 Fusarium strains in maize (Zea mays L.) samples with sifting their fumonisin contents. Furthermore, species-specific primers for the molecular identification of distinct strains amplified 2 fragments of 578 and 800 bp in Fusarium verticillioides, while a single 585 bp band was amplified in Fusarium proliferatum. Accordingly, 24 isolates out of 41 were identified as F. verticillioides, and 13 isolates were identified as F. proliferatum. The fumonisin-producing and non-producing Fusarium strains were identified using the VERTF-1/VERTF-2 primers. A total of 24 isolates of F. verticillioides were positively scored based on the amplification of a single 400 bp fragment. The highest and lowest fumonisin content, as measured using an enzyme-linked immunosorbent assay (ELISA), belonged to strains MS1 and MG3, respectively, and ranged from 960-12673 and 4.07-23 ppm, respectively. Additionally, the mating type test showed that the sexual form of the studied Fusarium species could possibly belong to the A and D mating populations. In vivo and in vitro pathogenicity tests revealed a high susceptibility.

“…Sexual reproduction may be occurring in the field, since one isolate of F. sacchari was obtained from an ascospore cirrus; moreover, the proportion of MAT‐1 and MAT‐2 observed amongst the progeny was consistent with a Mendelian ratio of 1:1. Records of the FFSC sexual phase occurring under natural conditions are available for Fusarium xylarioides Steyaert, Fusarium udum Butler, F. sacchari , F. verticillioides , Fusarium fujikuroi Nirenberg and F. subglutinans , where perithecia of these species were found associated with host material in the field (Edwards, 1935; Egan et al, 1997; Rai & Upadhyay, 1982; Summerell et al, 1998; Watanabe & Umehara, 1977).…”

Isolates from the Fusarium fujikuroi species complex, mainly F. sacchari, have been reported to be the causal agents of pokkah boeng in sugarcane in Brazil. However, inadequate information was available on the occurrence and genetic diversity of F. sacchari in Northeast Brazil, which is a limiting factor on management. Thus, isolates of F. subglutinans sensu lato from sugarcane plants with symptoms of pokkah boeng were evaluated using the sexual cross-fertility to determine species. All the isolates produced black perithecia when they were crossed with the test isolates of F. sacchari.Three weeks after the crossing, the formation of fertile ascospores cirri was observed.Thirty-four isolates were self-sterile hermaphrodites, while 21 were fertile only as males. Five isolates were homothallic. The effective size [N e(f) ] of the population as a function of the frequency of hermaphrodites and female sterile strains was 95.5%.The F. sacchari isolates were separated into four genetic groups independent of geographic location. The mean of polymorphism among all populations was 79%, and the average unbiased genetic diversity (uh) was considered moderate (0.31). This study in addition to confirming that F. sacchari as the main species associated with pokkah boeng in sugarcane in Northeast Brazil, reveals the relationship of mating type and genetic diversity of F. sacchari. The unrestricted gene flow between regions is probably the best explanation for the low geographic correlation. This knowledge will help in the adoption of management measures with fungicides or resistant cultivars.

“…Alternaria isolates were identified phenotypically to the genus level depending on the shape, color and size of the conidia based on the taxonomic keys that mentioned by [13]. While Fusarium isolates were identified to the genus level depending on the shape and color of the colony, additionally the shape of the conidiophore, Microconidia and Macroconidia based on the taxonomic keys [14].…”

Fruit bodies of three Ganoderma isolates coded by Has.AA-6, Has.AA-7 and Has.AA-8 were collected from the trunks of Poplar, Sidr and Apricot trees, respectively, from some districts in Salah al-Din Governorate. It was phenotypically diagnosed to the genus level depending on the shapes, colors and sizes of the fruit bodies as well as the internal tissues and basidiospores. Molecular diagnoses to the species level was carried out depending on the percentage of identical 5.8S rRNA gene sequences with strains of fungi in the World Genetic Bank at the NCBI. Ganoderma isolates identified as G. applanatum Has.AA-6, G. lucidum Has.AA-7 and G. resinaceum Has.AA-8, and recorded in the World Genetic Bank at the NCBI under the accession number ON834523.1, ON834541.1 and ON834527.1, respectively. The results of cultivation of Ganoderma spp. showed a superiority of the biological efficiency of the corn cobs supplemented with wheat bran, which were 27.73, 31.27, 31.64 and 32.07%, compared to unsupplemented this medium, as the biological efficiency reached 26.18, 26.67, 27.21, 27.22, and 27.22% for G. lucidum, G. applanatum, G. resinaceum and G. resinaceum 1049 respectively. The role of the filtrate, mycelium biomass and fruit bodies of Ganoderma spp. against the pathogenic fungi F. oxysporum and A. tenuissima was studied, the results showed that the extracts of all Ganoderma spp. have a significant superiority in inhibiting the growth of both pathogenic fungi compared to the control treatment, the alcoholic extract of G. resinaceum fruit bodies recorded the highest inhibition of the F. oxysporum and A. tenuissima in which the colonies diameters reached 3.21 and 2.4cm, respectively, while G. lucidum gave the lowest colony diameter of F. oxysporum and A. tenuissima, which reached 2.61 and 2.25 cm, respectively, compared to with a diameter of 8.5 cm for colonies of both pathogenic fungi in the control.
