Project description:The maize smut fungus, Sporisorium reilianum f. sp. zeae, which is an important biotrophic pathogen responsible for extensive crop losses, infects maize by invading the root during the early seedling stage. In order to investigate disease-resistance mechanisms at this early seedling stage, digital gene expression (DGE) analysis, which applies a dual-enzyme approach (DpnII and NlaIII), was used to identify the transcriptional changes in roots of Huangzao4 (susceptible) and Mo17 (resistant) after inoculation with teliospores of S. reilianum. Before and after inoculation, pathogenesis-related genes were differentially regulated and enzymes involved in controlling reactive oxygen species (ROS) levels showed different activity between Huangzao4 and Mo17, which can potentially lead to changes in the growth of S. reilianum and ROS production in maize. Moreover, lignin depositions of roots were also changed differentially during root colonization of hyphae between Huangzao4 and Mo17. These results suggest that the interplays between S. reilianum and maize during the early infection stage involve many interesting transcriptional and physiological changes, which offer several novel insights for understanding the mechanisms of resistance to the fungal infection.

Project description:Head smut of maize, which is caused by the Sporisorium reilianum f. sp. Zeae (Kühn), has been a serious disease in maize. In order to find head smut resistant candidate genes, microarrays were used to monitor the gene expression profiles between disease resistant near isogenic lines (NIL) L282 and L43, highly resistant inbred line Q319 and highly susceptible inbred line Huangzao4 after 0 to7 days post inoculation of S.reiliana by artificial inoculation method.

Project description:The maize smut fungi Ustilago maydis and Sporisorium reilianum are closely related and have similar genomes in terms of size and synteny. While U. maydis induces tumors locally at sites of infection, S. reilianum systemically colonizes the host and causes symptoms in the inflorescences. To investigate the genetic basis of these differences, an interspecific recombinant hybrid (rUSH) with the mating type system of S. reilianum was generated. rUSH exhibited extensive in-planta proliferation, showing a S. reilianum-like phenotype at all developmental stages except teliospore formation. Transcriptome profiling revealed that expression of pathogenicity-related effector gene orthologs was induced in rUSH, but not in a wild-type hybrid control. Multiple transcriptome comparisons identified 253 differentially expressed one-to-one effector orthologs with distinct regulatory patterns, including cis-, trans-, and rUSH-specific regulation. Functional analysis via CRISPR/Cas9 mutagenesis uncovered three novel virulence factors among the rUSH-specific regulated effectors. Ultimately, rUSH facilitated to identify the transcription factor UmHdp2 as key regulator of U. maydis-induced tumorigenesis. Together, these findings highlight the utility of a recombinant, interspecific hybrid in unraveling the molecular mechanisms underlying pathogenic differences in closely related fungal pathogens.
