Project description:Watermelon (Citrullus lanatus) is one of the most important vegetable crops in the world and accounts for 20% of the world’s total area devoted to vegetable production. Fusarium wilt of watermelon is one of the most destructive diseases in watermelon worldwide. Transcriptome profiling of watermelon during its incompatible interactions with Fusarium oxysporum f.sp. niveum (FON) was generated using an Agilent custom microarray which contains 15,000 probes representing approximately 8,200 watermelon genes. A total of 24, 275, 596, 598, and 592 genes that are differentially expressed genes between FON- and mock-inoculated watermelon roots at 0.5, 1, 3, 5 and 8 days post inoculation (dpi), respectively, were identified. Bioinformatics analysis of these differentially expressed genes revealed that during the incompatible interaction between watermelon and FON, the expression of a number of pathogenesis-related (PR) genes, transcription factors, signaling/regulatory genes, and cell wall modification genes, was significantly induced. A number of genes for transporter proteins such as aquaporins were down-regulated, indicating that transporter proteins might contribute to the development of wilt symptoms after FON infection. In the incompatible interaction, most genes involved in biosynthesis of jasmonic acid (JA) showed expressed stronger and more sustained than those in compatible interaction in FON-infected tissues. Similarly, genes associated with shikimate-phenylpropanoid-lignin biosynthesis were also induced in incompatible interaction, but expression of these genes were not changed or repressed in the compatible interaction. Fusarium oxysporum f.sp. niveum induced gene expression in watermelon root was measured at 0.5,1d, 3d, 5d and 8d after inoculation. Sample inoculated with water were used as the mock controls. Three independent experiments were performed.

Project description:To explore the presence of milRNA in Fusarium oxysporum f. sp. niveum (Fon) and evaluate their expression at different propagules, two categories of sRNAs were identified from Fon hyphae and microconidia by using illumina sequencing. A total of 650,960 and 561,114 unique sRNAs were obtained from the hyphae and microconidia samples. With a previously constructed pipeline to search for microRNA, we then identified 74 and 56 miRNA-like small RNAs (milRNAs) candidates in hyphae and microconidia based on the short hairpin structure analysis, respectively. Global expression analysis showed an extensively differential expression of sRNAs between two propagules. Altogether, 78 significantly differently expressed milRNAs were identified in two libraries. Target prediction revealed 2 interesting genes involved in trichothecene and necrosis and ethylene-inducing peptide 1 (NEP1) biosynthesis predicted to be down regulated by Fon-miR7696a-3p and Fon-miR6108a. These two milRNAs were further validated by qRT-PCR and showed a well consistency with sequencing. The negative correlation expression levels between these two milRNAs and their targets genes imply that they might play a role in trichothecene and NEP1 biosynthesis, and this negative regulation for toxin related gene expression are more specific in microconidia. The present study provides the firstly large-scale characterization of milRNAs in Fon and the comparison between hyphae and microconidia propagules gives a clue on how milRNAs involves in toxin biosynthesis.
