Plant growth and development under challenging environments has selected for sophisticated mechanisms to sense, translocate, store, and metabolize carbon. The complexity of plant defence responses requires an abundant (but ultimately limited) supply of energy, mainly derived from primary metabolic processes. Primary metabolite availability and distribution is therefore regulated. Upon pathogen infection, several genes associated with primary metabolic pathways are induced, namely, those involved in the synthesis or degradation of carbohydrates, amino acids, and lipids. Considering the importance of plant hormones, reactive oxygen species (ROS), and carbohydrate metabolism to plant-pathogen interactions, the chloroplast represents a prime target for pathogen manipulation, linking photosynthesis with plant immunity. In addition, the bioenergetic and ROS generating organelles (chloroplast, mitochondria and peroxisomes) are also target for pathogen manipulation. The fine-tuning of inter-organelle metabolism and intra- and inter-cellular trafficking, as well as the dynamic role for bioenergetic organelles in the regulation of immune responses needs to be unveiled.
Due to its pivotal role in primary metabolism, the chloroplast will be the principal focus of this topic. The modulation of chloroplast structure, metabolism, signalling pathways, key photosynthetic molecules, ROS and membrane transport will be analysed as part of biotic stress responses. Channels and carriers and their regulation are also envisaged. In addition to the relevance of basic knowledge on bioenergetic organelles, advances are unveiling promising insights to improve plant productivity and disease resistance.
This article collection welcomes manuscripts that contribute to the understanding of plant defense mechanisms to different pathogens (eg. bacteria, oomycetes, fungi, nematodes) and their interaction/modulation with primary metabolism, obtained from the application of different approaches (physiological, transcriptomic, proteomic, metabolomic, etc). Manuscripts within the general scope of plant-pathogen interactions will be also taken in consideration. We encourage submission of Original Research articles, Mini-Reviews, Perspectives and Opinion articles on the following topics, but are not limited to:
• Primary metabolism and plant immunity
• Interactions between the plant immune system and chloroplastic, mitochondrial and peroxisomal metabolism
• Plant hormones and their role in plant immunity with respect to primary metabolism
• Organelle trafficking and plant immunity
