Abstract

Abstract:

【Background】 Fusarium crown rot (FCR), caused by Fusarium pseudograminearum, is one of the newly-occurred destructive diseases in the main wheat-growing region of China. Autophagy is an evolutionarily conserved cellular process that regulates the growth, development and infection of different phytopathogenic fungi. However, the role of autophagy in F. pseudograminearum is still unknown.【Objective】 To clarify the role of the autophagy gene FpAtg3 in the growth and pathogenicity of F. pseudograminearum, understand the mechanisms of the fungal infection, and to provide a theoretical basis for FCR prevention.【Method】 The known Atg3 proteins of different fungi were downloaded from NCBI, and the MEGA 5.05 was used to construct the phylogenetic tree of Atg3 proteins. The Split-PCR approach was used to generate FpAtg3 gene-replacement constructs, and then the FpAtg3 deletion mutants (ΔFpAtg3) were constructed by polyethylene glycol (PEG)-mediated protoplast fungal transformation, and obtained by hygromycin resistance screening and PCR detection. The sequence of FpAtg3 and its native promoter was amplified and fused in pKNTG vector. The plasmid of pKNTG-FpAtg3 was then introduced into ΔFpAtg3 protoplasts for the complementation assay. The hyphal growth and colony morphology of the wild type, ΔFpAtg3 and the complementary (FpAtg3-C) strains were assayed on PDA, CM and MM plates. The hyphal blocks were cultured on PDA plates for hyphal morphology and hyphal fusion test; hyphal blocks were introduced into liquid CMC medium to assess conidiation and conidia morphology; conidia were cultured on Petri dishes to explore conidial anastomosis tube (CAT)-mediated fusion. The hyphal blocks were inoculated on wheat coleoptiles and barley leaves to explore pathogenicity, and the pot-culture experiment was performed for FCR assay. Congo red, sodium dodecyl sulphate (SDS) and H₂O₂ reagents were added to PDA plates to determine the F. pseudograminearum responses to cell wall, cell membrane and oxidative stresses, respectively.【Result】 Atg3 homologous proteins from different fungi were highly conserved and consistent with the direction of species evolution. The FpAtg3 had a close relationship with Atg3 of Fusarium graminearum and Fusarium oxysporum. The ΔFpAtg3 and FpAtg3-C strains were obtained. The phenotypic measurements showed that compared to wild type and FpAtg3-C strains, ΔFpAtg3 exhibited significantly reduced colony growth rates and aerial hypha, curved hypha, reduced conidiation, shorter in length and fewer in septa; ΔFpAtg3 also showed significantly reduced hyphal fusion rate and CAT-mediated fusion rate. The pathogenicity of ΔFpAtg3 on wheat coleoptiles and barley leaves was significantly reduced comparing to that of the wild type and FpAtg3-C strains. The reduced pathogenicity of ΔFpAtg3 was further examined on FCR. Furthermore, ΔFpAtg3 displayed more sensitive to cell wall, cell membrane and oxidative stress than that of the wild type and FpAtg3-C strains.【Conclusion】 Autophagy-related gene FpAtg3 plays important roles in growth, conidiation, hyphal fusion, pathogenicity and response to abiotic stresses of F. pseudograminearum.

Key words: Fusarium crown rot (FCR), Fusarium pseudograminearum, Atg3, hyphal fusion, pathogenicity
