About this Research Topic
Lipids and their derivates take part in different biological functions related to (i) energy homeostasis and storage, (ii) carbon storage, (iii) the biosynthesis of membranes during replication and (iv) cellular signaling, including stress response. The membrane lipid composition of microorganisms changes upon the conditions to which the cells are exposed and it is increasingly becoming evident that lipids play an important role in the interaction – either beneficial, pathogenic or parasitic – of microorganisms with the environment and with other organisms, including plants. In this perspective, lipids are crucial at various stages of the host-pathogen interaction, such as recognition, signal transduction, and downstream responses. Membrane lipids and lipid-derived molecules either from the plant or the microbial organism play important roles during the infection process. For example, they are involved in establishing the membrane interface between the two organisms, are crucial for intracellular signaling and plant-host cross-talk. Lipids are involved in pathogen recognition by the host (e.g., ergosterol), and some lipids mediate the transfer of the infection signal.
The growing number of available genome sequences, as well as the employment of highly sensitive analytical techniques (i.e., gas chromatography and high-pressure liquid chromatography coupled to mass spectrometry) has led to the discovery of an increasing number of genes and derived products involved in the biosynthetic pathway of different lipids, which are shedding light upon additional lipid molecules involved in the plant-microbe interaction, and reveal lipid patterns that are common or distinct among interaction with pathogen, symbiont, or beneficial microbe.
This Research Topic aims to disseminate and increase the understanding of the role of lipids in the interaction between microorganisms and plants. Specifically, we are interested in exploring:
• The changes in the lipid membrane composition, and in the lipids and lipids derived molecules in the plant pathogens and microbes associated with plants in different growing conditions (i.e. in vitro and in planta)
• The role of lipids in mediating interactions between plants and microorganism
• The role of lipids in the biology of plant microorganisms
• The role of lipids in plant-microbial virulence
