About this Research Topic
Plants constantly face many kinds of abiotic and biotic stresses. One of the major threats is from many plant fungal, oomycete, viral, bacterial and nematode pathogens. Plant diseases caused by these pathogens reduce crop yield by 10-15% worldwide every year. Throughout the human history, plant diseases are responsible for many famines including the infamous Irish Potato Famine. Besides the negative impact on the yield, the quality of the infected crop will be adversely affected and the toxins produced by plant pathogens pose threat to human health.
During the co-evolution between plants and pathogens, plants developed elegant defense system against pathogen infection and plant pathogens deploy a variety of strategies to suppress plant innate immunity. A deeper understanding the molecular mechanisms on the activation of plant defense in plants and suppression of plant defense by plant pathogens will be crucial to develop effective ways to minimize the detrimental effects from plant diseases on human beings.
This Research Topic aims to increase our understanding on the molecular interactions between plants and pathogens. We welcome the submission of Original Research Articles, Reviews, Mini- review, Perspectives, and Methods related to, but not limited to, the following topics:
• MAMP-triggered immunity (MTI)
• Effector-trigged immunity (ETI)
• Avirulence (Avr) proteins and resistance (R) protein
• Salicylic acid-mediated plant defense
• Pathogen effectors
• Pathogen toxins
• PR proteins
• Reactive oxygen species
• Callose deposition
• MAP kinase pathway
• Systemic acquired resistance
• Mobile signals
• Hypersensitive responses
• Virus-induced gene silencing,
• Plant-nematode interaction
By focusing on the latest developments in both plant immunity and plant pathology, we hope to uncover the interconnections between and the biological relevance of the important molecular events during dynamic plant-pathogen interactions. The readers will particularly benefit from the wide range of systems used in these studies. Our collection of papers will showcase the defense and counter defense strategies deployed by plants and pathogens during their arms race. In addition, our wide range of listed topics will be helpful in revealing the big picture and common themes in molecular interactions between plants and pathogens.
