Project description:Oilseed rape (Brassica napus, B. napus) is one of the most important oil crops globally, contributing significantly to the world's supply of vegetable oil. However, its production is severely threatened by Sclerotinia stem rot, a disease caused by the broad-host-range fungus Sclerotinia sclerotiorum (Lib.) de Bary (S. sclerotiorum). We have investigated the gene expression of J9712 and W40-OE2 during different time periods of Sclerotinia sclerotiorum infection through RNA-Seq analysis.
Project description:Global transcriptome profiling of suceptible and tolerant lines of Brassica napus infected with Sclerotinia sclerotiorum using a petal inoculation method that mimics field conditions.
Project description:Sclerotinia sclerotiorum is a broad-host range necrotrophic pathogen which is the causative agent of Sclerotinia stem rot (SSR), and a major disease of soybean (Glycine max). A time course transcriptomic analysis was performed in both compatible and incompatible soybean lines to identify pathogenicity and developmental factors utilized by S. sclerotiorum to achieve pathogenic success.
Project description:This study provides a first large-scale cloning and characterization of Sclerotinia sclerotiorum milRNAs and milRNAs candidates. Two microRNA-like RNAs (milRNAs) and 42 milRNA candidates were identified by sequence analysis. These milRNAs and candidates provide new insights into the functional roles of small RNAs and adds new resources for the study of plant pathogenic fungi. We constructed a small RNA library from Sclerotinia sclerotiorum.
Project description:Plants deploy pattern recognition receptors to detect microbe- and damage-associated molecular patterns. Arabidopsis thaliana receptor-like protein RLP30 contributes to innate immunity to the necrotrophic fungus Sclerotinia sclerotiorum by recognizing SCLEROTINIA CULTURE FILTRATE ELICITOR 1 (SCFE1). Here we show that the S. sclerotiorum small cysteine-rich protein SCP1 accounts for elicitor activity of SCFE1. RLP30 recognizes SCP1 and its homologs from divergent fungi and oomycetes, as well as an SCP1-unrelated and conserved pattern from bacterial Pseudomonads. Stable expression of RLP30 in Nicotiana tabacum confers enhanced immunity to bacterial, fungal, and oomycete pathogens. Unlike Arabidopsis, which requires intact SCP1 for RLP30-mediated immunity, other Brassicaceae and Solanaceae respond to smaller immunogenic SCP1 epitopes. We conclude that Arabidopsis RLP30 recognizes immunogenic patterns from three microbial kingdoms and that mechanistically different SCP1 perception has evolved in other plant species, likely as a result of convergent evolution.
