“…For example, Dioszegia , a basidiomycete taxon in the order Tremellales, has been reported from cereal and Arabidopsis 80,81 , potentially playing key roles within microbe–microbe interaction webs in leaf-associated microbiomes 11 . The genus Moesziomyces is represented by plant-pathogenic smut fungi 82 . However, a recent phylogenetic study of teleomorphic ( Moesziomyces ) and anamorphic ( Pseudozyma ) specimens 77 suggested that this Ustilaginaceae taxon could involve not only phytopathogenic species but also species with antifungal properties against the causal agent of cucumber powdery mildew ( Podosphaera fuliginea ) 83 or species that can induce resistance of host plants against fungal pathogens such as Botrytis cinerea 84 .…”

Bacteria and fungi form complex communities (microbiomes) in above- and below-ground organs of plants, contributing to hosts’ growth and survival in various ways. Recent studies have suggested that host plant genotypes control, at least partly, plant-associated microbiome compositions. However, we still have limited knowledge of how microbiome structures are determined in/on grafted crop plants, whose above-ground (scion) and below-ground (rootstock) genotypes are different with each other. By using eight varieties of grafted tomato plants, we examined how rootstock genotypes could determine the assembly of leaf endophytic microbes in field conditions. An Illumina sequencing analysis showed that both bacterial and fungal community structures did not significantly differ among tomato plants with different rootstock genotypes: rather, sampling positions in the farmland contributed to microbiome variation in a major way. Nonetheless, a further analysis targeting respective microbial taxa suggested that some bacteria and fungi could be preferentially associated with particular rootstock treatments. Specifically, a bacterium in the genus Deinococcus was found disproportionately from ungrafted tomato individuals. In addition, yeasts in the genus Hannaella occurred frequently on the tomato individuals whose rootstock genotype was “Ganbarune”. Overall, this study suggests to what extent leaf microbiome structures can be affected/unaffected by rootstock genotypes in grafted crop plants.

“…TEM of immunogold labelled (Coons, Creech and Jones 1941), sectioned samples provides high contrast images of intracellular and interface regions, offering insight into plant–fungal interactions at the molecular level (Howard 2001). For instance, Diagne-Leye et al (2013) recently used LM, TEM and SEM to show how Moesziomyces penicillariae , a smut fungus, adapts to the short life cycle of pearl millet. Cryo-SEM images of sample surfaces when combined with focused ion beam milling and energy-dispersive X-ray spectroscopy, can be used to localize and identify fungal and plant secretions in response to their interaction (Dahms and Kaminskyj 2008).…”

Fungi interact with plants in various ways, with each interaction giving rise to different alterations in both partners. While fungal pathogens have detrimental effects on plant physiology, mutualistic fungi augment host defence responses to pathogens and/or improve plant nutrient uptake. Tropic growth towards plant roots or stomata, mediated by chemical and topographical signals, has been described for several fungi, with evidence of species-specific signals and sensing mechanisms. Fungal partners secrete bioactive molecules such as small peptide effectors, enzymes and secondary metabolites which facilitate colonization and contribute to both symbiotic and pathogenic relationships. There has been tremendous advancement in fungal molecular biology, omics sciences and microscopy in recent years, opening up new possibilities for the identification of key molecular mechanisms in plant–fungal interactions, the power of which is often borne out in their combination. Our fragmentary knowledge on the interactions between plants and fungi must be made whole to understand the potential of fungi in preventing plant diseases, improving plant productivity and understanding ecosystem stability. Here, we review innovative methods and the associated new insights into plant–fungal interactions.

“…Moesziomyces spp. have been detected in the phyllosphere and reported as plant and human pathogens ( 1 – 5 ), plant pathogen antagonists ( 6 – 9 ), saprotrophs decomposing biodegradable polymers and plastics ( 10 , 11 ), and biosurfactant producers ( 12 ). We isolated M. antarcticus RS1, a core member of the rice seed microbiome ( 13 ), from surface-sterilized seeds of the rice cultivar Nakdong incubated on rice extract agar medium at 23.5°C for 14 days.…”

Moesziomyces antarcticus (anamorph: Pseudozyma antarctica ) is a basidiomycetous yeast in the Ustilaginaceae family and is a core member of the rice seed microbiome. M. antarcticus RS1 was isolated from surface-sterilized rice seeds. This 18.287 Mb draft genome of M. antarcticus RS1 is comprised of a 60.8% GC content and 6,817 protein-coding genes.
