“…This report is the first of F. andiyazi occurrence in Malaysia as well as in Southeast Asia, and the first report of F. andiyazi on rice in Malaysia. F. andiyazi was first described by Marasas et al [16] from sorghum in Africa and the United States and has also been reported from rice seed samples from Africa and Asia [10]. In the present study, swollen cells were observed, however, the swollen cells produced by F. verticillioides and pseudochlamydospores formed by F. andiyazi were difficult to distinguish which may explain why the structures were not easily distinguishable on CLA.…”

The objective of this study was to identify Fusarium species in the Gibberella fujikuroi species complex from rice, sugarcane and maize as most of the Fusarium species in the species complex are found on the three crops. Isolates used were collected from the field and obtained from culture collection. The Fusarium isolates were initially sorted based on morphology and identifications confirmed based on the DNA sequence of the translation elongation factor 1-α (TEF-1α) gene. Based on the closest match of BLAST analysis, five species were recovered, namely, F. sacchari, F. fujikuroi, F. proliferatum, F. andiyazi and F. verticillioides. This is the first report regarding F. andiyazi from rice in Malaysia and Southeast Asia. The phylogenetic tree generated by using the neighbor joining method showed that isolates from the same species were grouped in the same clade. The present study indicated that Fusarium species in the G. fujikuroi species complex are widespread in rice, sugarcane and maize in Peninsular Malaysia. The findings also suggest that the use of morphological characters for identification of Fusarium species in the G. fujikuroi species complex from the three crops will lead to incorrect species designation.

“…DNA sequences suffice to distinguish these species (44,54,55,76), with portions of the genes encoding β-tubulin (tub) and translocation elongation factor 1-α (tef) the most commonly analyzed sequences.

“…Isozymes were used previously to separate F. verticillioides, F. nygamai, and F. thapsinum (16). Thus far, F. andiyazi has been recovered from sorghum in Ethiopia, Nigeria, South Africa, and the United States (44). These two species can be distinguished based on their IDH alleles, for which F. andiyazi has the β allele and F. pseudonygamai has either the γ allele or a unique α/β allele.…”

“…DNA sequence data indicate that section Liseola is paraphyletic and that F. nygamai, F. napiforme, and F. dlamini are "phylogenetically nested within section Liseola" (54). The "G. fujikuroi species complex" now contains at least 46 phylogenetically distinct lineages (54,55), including 10 new species described by Nirenberg and O'Donnell (52), two species described by Nirenberg et al (53), and most recently, F. andiyazi (44) In addition to maize and sorghum, Booth (3) stated that F. moniliforme also occurs on rice and sugarcane, is a "major para-site" of several members of the family Gramineae, and occurs on at least 31 other families of plants. This purported host range of F. moniliforme was extended even further by Bacon et al (1), who calculated that 11,000+ species of plants could serve as a host for this fungus.…”

“…All the above taxa were later reduced to a single species, F. moniliforme Sheldon emend. These taxonomic treatments differed somewhat from each other, but only two of them (26,44) differentiated between F. moniliforme (or F. verticillioides) from maize and sorghum, whereas some stated explicitly that F. moniliforme occurs on both maize and sorghum (3,9,33,74). Booth (3) initiated the re-evaluation of the species in section Liseola that is still in progress by separating F. moniliforme var.…”

Fusarium isolates recovered from sorghum and millet are commonly identified as F. moniliforme, but with the recognition of new species in this group, the strains given this name are being re-evaluated. We analyzed five strains each from five Fusarium species (F. andiyazi, F. nygamai, F. pseudonygamai, F. thapsinum, and F. verticillioides) often associated with sorghum and millet for their ability to produce fumonisin and moniliformin, their toxicity to ducklings, and their ability to cause disease on sorghum seedlings in vitro. These species can be distinguished with isozymes (fumarase, NADP-dependent isocitrate dehydrogenase, and malate dehydrogenase) and with banding patterns resulting from amplified fragment length polymorphisms. Two species, F. pseudonygamai and F. thapsinum, produced high levels of moniliformin, but little or no fumonisins, and were consistently highly toxigenic in the duckling tests. Two species, F. verticillioides and F. nygamai, produced high levels of fumonisins, but little or no moniliformin, and also were toxigenic in the duckling tests. F. andiyazi produced little or no toxin and was the least toxigenic in the duckling tests. In sorghum seedling pathogenicity tests, F. thapsinum was the most virulent followed by F. andiyazi, then F. verticillioides, and finally F. nygamai and F. pseudonygamai, which were similar to each other. Thus, these five species, which would once have all been called F. moniliforme, differ sufficiently in terms of plant pathogenicity and toxin production profile, that their previous misidentification could explain inconsistencies in the literature and differences observed by researchers who thought they were all working with the same fungal species.
