Pathogenesis-related genes of entomopathogenic fungi

Area of Science:

• Mycology
• Entomology
• Plant Pathology

Background:

• Fungi causing insect diseases are known as entomopathogenic fungi.
• These fungi are utilized as microbial insecticides for pest management.
• Their mode of action involves conidia attachment, germination, penetration, growth, and secondary conidia production.

Purpose of the Study:

• To review the information mechanism of entomopathogenic fungi.
• To describe the genetic strategies employed by fungi at each infection step.
• To present an approach for studying fungal modes of action.

Main Methods:

• Gene knock-out analysis
• RNA-sequencing analysis
• Literature review of fungal infection mechanisms

Main Results:

• Entomopathogenic fungi infection is a six-step process: attachment, germination/appressorium, penetration, hemolymph growth, conidia production, and dispersal.
• Fungi utilize complex and specific gene expression patterns throughout the infection cycle.
• Genetic insights into each stage provide a basis for understanding fungal pathogenicity.

Conclusions:

• Understanding the genetic basis of entomopathogenic fungi's mode of action is crucial for optimizing their use in pest control.
• This review provides a framework for studying fungal pathogenicity at a genetic level.
• Further research into fungal gene mechanisms can enhance the efficacy of microbial insecticides.
