Transcriptional switching of host defence response to combat hemibiotrophic fungal infection

Hemibiotrophic fungal pathogens cause major destruction to food and industrial crops globally. Their dual infection phases appear to be a winning strategy. The pathogen establishes an initial colonisation biotrophically keeping the host cells alive. It then shifts to the notorious necrotrophic mode...

description Hemibiotrophic fungal pathogens cause major destruction to food and industrial crops globally. Their dual infection phases appear to be a winning strategy. The pathogen establishes an initial colonisation biotrophically keeping the host cells alive.

A better understanding of the molecular interaction at the early stage of infection is critical to save the infected crops. In this article, we integrate findings from different plant–pathogen pathosystems to provide a comprehensive evaluation about the defence response network, covering crops that are infected through the aerial and root tissues. The high-throughput transcriptomics and metabolomics approaches as well as relevant biochemical and physiological analyses have revealed key genes and cellular components associated with signalling pathways and defence responses during the biotrophic and necrotrophic phases.
