植物和病原真菌乙烯合成及感应研究进展

Ethylene is one of the important plant hormones, playing versatile roles in regulating almost all the growth and development stages throughout the plant life cycles. Moreover, ethylene can significantly influence plant responses to abiotic and biotic stresses. Fungi and terrestrial plants are closely related, and they can be mutually beneficial via symbiosis. Meanwhile, fungi also represent the main pathogen groups of plants. Plant pathogenic fungi commonly retain the ability to synthesize ethylene, while ethylene can also be sensed by fungal pathogens to regulate their metabolism, growth, and other processes. This paper summarizes the ethylene biosynthesis pathway and potential ethylene signal pathway of plant pathogenic fungi. By comparing the similarities and differences of ethylene synthesis and sensing in plants and fungi, it provides a reference for in-depth research and understanding of the roles of ethylene in the interaction between plants and pathogenic fungi.
