“…Moreover, there are several additional reports about the unprecedented occurrence of powdery mildew fungi on novel and/or unusual host plants that may point towards potential recent host jumps and host range expansions. These include the occurrence of Erysiphe monascogera on fruits of Styrax japonica (Shiroya et al, 2008), a yet unidentified Erysiphe species on papaya (Seress et al, 2021), Golovinomyces longipes on Matricaria chamomilla (Götz & Braun, 2022) and P. xanthii , E. quercicola and E. alphitoides on Australian native plants such as Acacia, Acalypha and Trema species (Kiss et al 2020). …”

The powdery mildew fungi (Erysiphaceae) are globally distributed plant pathogens with a range of more than 10,000 plant hosts. In this review, we discuss the long‐ and short‐term evolution of these obligate biotrophic fungi and outline their diversity with respect to morphology, lifestyle, and host range. We highlight their remarkable ability to rapidly overcome plant immunity, evolve fungicide resistance, and broaden their host range, for example, through adaptation and hybridization. Recent advances in genomics and proteomics, particularly in cereal powdery mildews (genus Blumeria), provided first insights into mechanisms of genomic adaptation in these fungi. Transposable elements play key roles in shaping their genomes, where even close relatives exhibit diversified patterns of recent and ongoing transposon activity. These transposons are ubiquitously distributed in the powdery mildew genomes, resulting in a highly adaptive genome architecture lacking obvious regions of conserved gene space. Transposons can also be neofunctionalized to encode novel virulence factors, particularly candidate secreted effector proteins, which may undermine the plant immune system. In cereals like barley and wheat, some of these effectors are recognized by plant immune receptors encoded by resistance genes with numerous allelic variants. These effectors determine incompatibility (“avirulence”) and evolve rapidly through sequence diversification and copy number variation. Altogether, powdery mildew fungi possess plastic genomes that enable their fast evolutionary adaptation towards overcoming plant immunity, host barriers, and chemical stress such as fungicides, foreshadowing future outbreaks, host range shifts and expansions as well as potential pandemics by these pathogens.

The powdery mildew Erysiphe magnifica (Erysiphales, Ascomycota) has been recorded for the first time on lotus (Nelumbo nucifera) based on a collection from the Botanical Garden in Frankfurt am Main, Germany. This powdery mildew previously known only from Magnolia species was identified by a combination of light and scanning electron microscopic investigation of ascomata and the Oidium stage, and comparison of ITS DNA sequences. This finding is discussed with respect to the narrow host specificity concept used in Erysiphales taxonomy, the effect of lotus leaf surface on fungal infection, and the extending geographical distribution of powdery mildews.
