Finished Genome of the Fungal Wheat Pathogen Mycosphaerella graminicola Reveals Dispensome Structure, Chromosome Plasticity, and Stealth Pathogenesis
The genome of M. graminicola was sequenced completely and found that it contained very few genes for enzymes that break down plant cell walls, which was more similar to endophytes than to pathogens, which may have evolved from endophytic ancestors.

It is concluded that MgHog1 is a new pathogenicity factor involved in the regulation of dimorphism in M. graminicola and is osmosensitive, resistant to phenylpyrrole and dicarboximide fungicides, and do not melanize.

This work analysed the mating-type loci of phylogenetically closely related Ascochyta and Phoma species that co-occur on the same hosts, and revealed that the heterothallic D. vitalbina (Phoma anamorph) is more closely related to the homothallic C. clematidina than to theheterothallic P. pinodes.
Evolutionary Dynamics of Mating-Type Loci of Mycosphaerella spp. Occurring on Banana
The mating-type loci of the examined Mycosphaerella species are expanded, containing two additional MyCosphaerella-specific genes in a unique genomic organization, showing the great flexibility of the MAT loci in general and of the Mycospherella species in particular.

The sequenced P. fijiensis genome will aid in developing fungicide treatment schedules to combat this pathogen and in improving the efficiency of banana breeding programs.

Drug transporters of the filamentous fungi Aspergillus nidulans (Eidam) Winter, Botrytis cinerea Pers and Mycosphaerella graminicola (Fückel) Schroter that function in fungicide sensitivity and resistance are described.

Variations in azole susceptibility in laboratory strains of M. graminicola are proposed to be mediated by multiple mechanisms, including ATP-binding cassette (ABC) transporter genes MgAtr1 to M gAtr5 and the sterol P450 14α-demethylase gene, CYP51.
MgMfs1, a major facilitator superfamily transporter from the fungal wheat pathogen Mycosphaerella graminicola, is a strong protectant against natural toxic compounds and fungicides.

The results indicate that MgMfs1 is a true multidrug transporter that can function as a determinant of pathogen sensitivity and resistance to fungal toxins and fungicides.

Overexpression of some of these transporters can lead to the development of resistance to chemically-unrelated compounds, a phenomenon described as multidrug resistance (MDR), which can impose a serious threat to the effective control of pathogenic fungi.

Results show that ABC transporters from M. graminicola play a role in protection against toxic compounds of natural and artificial origin.
