“…High levels of genetic variation were also shown by 67 haplotypes produced among isolates of F. proliferatum from various hosts and substrates. The results are similar to a study by Láday et al (2008) of which 16 haplotypes were detected among 184 isolates of F. proliferatum using RFLP of mtDNA. Heng et al (2012) also reported 53 haplotypes were detected among 74 isolates of Fusarium species from maize, sugarcane and rice using RFLP-IGS analysis.…”

Fusarium proliferatum is a well-known plant pathogenic fungus-infected many crops. The present study was carried out to molecularly identified and characterized morphologically identified F. proliferatum from various hosts and substrates. The species identity of the isolates was verified as F. proliferatum based on TEF-1α sequences and phylogenetic analysis indicated high intraspecific variations. RFLP-IGS analysis also indicated high intraspecific variations of which the isolates were clustered into three RFLP Groups (I, II, and III) comprising 67 IGS haplotypes. Seventy isolates were crossed-fertile and proven to be members of mating population D (MP-D) of Gibberella fujikuroi while four isolates were infertile. A high level of intraspecific variations is vital for F. proliferatum adaptation and survival in the host and environment. Correct species identification of F. proliferatum is important as the fungus is a well-known plant pathogen and mycotoxin producer. Correct species identity is also essential to strategize suitable disease control methods as well as to predict their host range and mycotoxin production.

“…One of these is the previously mentioned ORF227 in intron 2 of cob. An uORF of 125 amino acids was found in the intergenic region between nad5 and cob, and it has similarity (1 e À12 ) to the plasmid-encoded B type DNA polymerase of the pFP1 linear DNA plasmid of Fusarium proliferatum (Láday et al, 2008). This ORF is likely a remnant of an integrated plasmid (Cahan and Kennell, 2005) and it is not likely to F. oxysporum F11 F. verticillioides 7600 F. solani MPVI Fig.…”

“…Similarly, the telomeres of the mitochondrial plasmids from the slime mold P . polycephalum and the fungi Fusarium proliferatum and Neurospora intermedia all contain a 50–700-nt piece of a DNA polymerase gene ( DNApol ) (Chan et al 1991; Takano et al 1994; Láday et al 2008). In the plasmid subtelomeres of the plant Brassica napus and fungi Pichia kluyveri and Podospora anserina , a DNApol and an RNA polymerase gene ( RNApol ) have homogenized with one another, so that the first 32–72 residues of their deduced N-terminal amino acid sequences are identical (fig.…”

Recently, it was shown that gene conversion between the ends of linear mitochondrial chromosomes can cause telomere expansion and the duplication of subtelomeric loci. However, it is not yet known how widespread this phenomenon is and how significantly it has impacted organelle genome architecture. Using linear mitochondrial DNAs and mitochondrial plasmids from diverse eukaryotes, we argue that telomeric recombination has played a major role in fashioning linear organelle chromosomes. We find that mitochondrial telomeres frequently expand into subtelomeric regions, resulting in gene duplications, homogenizations, and/or fragmentations. We suggest that these features are a product of subtelomeric gene conversion, provide a hypothetical model for this process, and employ genetic diversity data to support the idea that the greater the effective population size the greater the potential for gene conversion between subtelomeric loci.
