Ca2+ Signalling in Plant Biotic Interactions

About this Research Topic

Recently, with the emergence of new tools such as the development of genetically encoded Ca2+ sensors that can monitor Ca2+ fluxes in real-time and improvements in confocal microscopy that allows for much higher spatial resolution, the field of Ca2+ signalling has gained significant momentum. We believe it is timely to propose a Research Topic for Frontiers in Plant Science dedicated specifically to Ca2+ signalling in the context of plant biotic interactions. Plants utilize Ca2+ to respond to many external threats, but also when establishing beneficial interactions with microbes. Ca2+ signalling includes Ca2+ fluxes, i.e. Ca2+ channels/pumps and their regulation and interaction with other proteins, as well as downstream signalling triggered by the influx of Ca2+, such as Ca2+ binding proteins, kinase activation and Ca2+-regulated transcription factors/regulators. One focus will be the interaction of plants with pathogenic microorganisms. Recently, there have been some breakthroughs in Ca2+ signalling in the context of PTI. But there are many unanswered questions in ETI, systemic signalling, interactions with necrotrophic pathogens, and insects. Another area of interest would be interactions of the plant root, such as with soil microorganisms and nematodes. Besides pathogenic interactions, Ca2+ signalling in the context of symbiotic interactions should also be included. How can plants distinguish between friend and foe? Finally, another aspect could be the effects of environmental factors on the outcome of plant-pathogen interactions.

 

This Research Topic aims to collect articles addressing the latest advances in Ca2+ signalling research that focus on but are not limited to the following aspects:

·      Ca2+ fluxes, channels/pumps at the plasma membrane, tonoplast, nucleus, or organelles

·      Ca2+ signalling, receptor-channel complexes, immediate downstream signalling upon perception

·      Ca2+ signalling in response to biotroph and necrotrophy pathogens

·      The role of Ca2+ in long-distance/systemic signalling

·      Ca2+ signalling in the root upon pathogen/symbiont interactions

·      The role of Ca2+ signalling in connecting environmental effects to biotic interactions

·      Plant-insect interactions


Keywords: Calcium, Signalling, Biotic Stress, Calcium fluxes, Ca2+


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
