Project description:We previously revealed developmental regulation over UV repair capacity in the soilborne pathogen Fusarium oxysporum (F. oxysporum). We demonstrated that photoreactivation assisted survival and repair were high during early stages of germination and low at later stages. In agreement, the expression of the UV specific repair genes photolyase and uvde showed opposite trends. While early on photolyase is induced and uvde is reduced, the trend is reversed later. Here, we tested the dynamic of transcription of photolyase, UV survival, repair capacity, and UV induced mutagenesis in the foliar pathogen Fusarium mangiferae. Unlike F. oxysporum, neither did we observe developmental control over photoreactivation dependent repair nor the changes in gene expression of phr1 and uvde throughout the experiment. Similarly, photo-reactivation assisted reduction in UV induced mutagenesis was similar throughout the development of F. mangiferae but fluctuated during the development of F. oxysporum. To generate hypotheses regarding the recovery of F. mangiferae after UV exposure, an RNAseq analysis was performed after irradiation at different timepoints. The most striking effect of UV on F. mangiferae was developmental-dependent induction of translation related genes. We further report a complex dynamic response that involves translation, cell cycle and lipid biology related genes.

Project description:Malformation caused by Fusarium mangiferae is one of the most destructive mango diseases affecting the canopy and floral development, leading to dramatic reduction in fruit yield. To further understand the mechanism of interaction between mango and F. mangiferae, we monitored the transcriptome profiles of buds from susceptible mango plants, which were challenged with F. mangiferae. More than 99 million reads were deduced by RNA-sequencing and were assembled into 121,267 unigenes. Based on the sequence similarity searches, 61,706 unigenes were identified, of which 21,273 and 50,410 were assigned to gene ontology categories and clusters of orthologous groups, respectively, and 33,243 were mapped to 119 KEGG pathways. The differentially expressed genes of mango were detected, having 15,830, 26,061, and 20,146 DEGs respectively, after infection for 45, 75, and 120 days. The analysis of the comparative transcriptome suggests that basic defense mechanisms play important roles in disease resistance. The data also show the transcriptional responses of interactions between mango and the pathogen and more drastic changes in the host transcriptome in response to the pathogen. These results could be used to develop new methods to broaden the resistance of mango to malformation, including the over-expression of key mango genes.

Project description:Fusarium fujikuroi is a biotechnologically important fungus due to its almost unique ability to produce gibberellic acids (GAs), a family of phytohormones. The fungus was described about 100 years ago as the causative agent of Bakanae (M-bM-^@M-^\foolish seedlingM-bM-^@M-^]) disease of rice. Apart from GAs, the fungus is known to produce pigments and mycotoxins, but the biosynthetic genes are known for only eight products. Here we present a high-quality genome sequence of the first member of the Gibberella fujikuroi species complex (GFC) that allowed de novo genome assembly with 12 scaffolds corresponding to the 12 chromosomes. In this work we focused on identification of all potential secondary metabolism-related gene clusters and their regulation in response to nitrogen availability by transcriptome, proteome, HPLC-FTMS and ChIP-seq analyses. We show that most of the cluster genes are regulated in a nitrogen-dependent manner, and that expression profiles fit to proteome and ChIP-seq data for some but not all clusters. Comparison with genomes of all available Fusarium species, including the recently sequenced F. mangiferae and F. circinatum, showed only a small number of common gene clusters and provides new insights into the divergence of secondary metabolism in the genus Fusarium. Phylogenetic analyses suggest that some gene clusters were acquired by horizontal gene transfer, while others were present in ancient Fusarim species and have evolved differently by gene duplications and losses. One polyketide synthase (PKS) and one non-ribosomal peptide synthetase (NRPS) gene cluster are unique for F. fujikuroi. Their products were identified by combining overexpression of cluster genes with HPLC-FTMS-based analyses. In planta expression studies suggest a specific role of the PKS19 product in rice infection. Our results indicate that comparative genomics together with the used genome-wide experimental approaches is a powerful tool to uncover new secondary metabolites and to understand their regulation at the transcriptional, translational and epigenetic levels.
