Peroxisomal metabolic function is required for appressorium-mediated plant infection by Colletotrichum lagenarium.
Peroxisomes are organelles that perform a wide range of metabolic functions in eukaryotic cells. However, their role in fungal pathogenesis is poorly understood. Here we report that ClaPEX6, an ortholog of PEX6, is required for the fungus Colletotrichum lagenarium to infect host plants. ClaPEX6 was identified in random insertional mutagenesis experiments aimed at elucidating genes involved in p...
متن کاملThe Mitogen-Activated Protein Kinase CgMK1 Governs Appressorium Formation, Melanin Synthesis, and Plant Infection of Colletotrichum gloeosporioides
The fungus Colletotrichum gloeosporiodes infects plant hosts with a specialized cell called an appressorium, which is melanized and required for plant cell wall penetration. Here, we show that the mitogen-activated protein kinase CgMK1 governs appressorium formation and virulence in the poplar anthracnose fungus C. gloeosporioides. Deletion of CgMK1 impairs aerial hyphal growth and biomass accu...
متن کاملCgl-SLT2 is required for appressorium formation, sporulation and pathogenicity in Colletotrichum gloeosporioides
The mitogen-activated protein (MAP) kinase pathways has been implicated in the pathogenicity of various pathogenic fungi and plays important roles in regulating pathogenicity-related morphogenesis. This work describes the isolation and characterization of MAP kinase gene, Cgl-SLT2, from Colletotrichum gloeosporioides. A DNA sequence, including 1,633 bp of Cgl-SLT2 open-reading frame and its pro...
متن کاملA protein kinase from Colletotrichum trifolii is induced by plant cutin and is required for appressorium formation.
When certain phytopathogenic fungi contact plant surfaces, specialized infection structures (appressoria) are produced that facilitate penetration of the plant external barrier; the cuticle. Recognition of this hydrophobic host surface must be sensed by the fungus, initiating the appropriate signaling pathway or pathways for pathogenic development. Using polymerase chain reaction and primers de...
