Photosynthetic and Photorespiratory Organelles: Metabolism, Dynamics, and Signaling

About this Research Topic

Plastids (chloroplasts), mitochondria, and peroxisomes are essential organelles performing a variety of metabolic and signaling functions in plant development and environmental response. In addition to a plethora of organelle-specific functions, these three organelles interact physically and functionally to coordinate a number of metabolic and signaling pathways, ranging from photosynthesis and photorespiration, fatty acid metabolism, and biosynthesis of plant hormones to organelle retrograde signaling in changing environmental conditions. The morphology, abundance, and composition of these organelles differ between tissues and change in response to developmental and environmental cues to optimize plant growth and survival. Organellar signaling pathways are essential for plant survival and provide the necessary functional feedback to the nucleus to alter gene expression in response to the functional status of the plant.

This Research Topic seeks to highlight the latest advances in the understanding of the metabolic and signaling function, dynamic behavior, and inter-organellar interaction of chloroplasts, peroxisomes, and mitochondria. These organelles combined are referred to as energy organelles as they convert energy from sunlight into chemical energy that powers plant growth and ultimately supports almost all life on earth. These organelles are also biosynthetic factories that produce the various building blocks required for cell growth in terms of lipids, proteins, carbohydrates, amino acids, and nucleic acids. Emerging evidence also points to these organelles as sensors to the environments, as they are positioned at the crossroads between growth and stress response, two opposing demands for plants. An understanding of how these two demands are balanced will lead to the generation of knowledge to optimize plant growth, reproduction and defense.

We welcome submissions of original research articles, mini-reviews, perspectives/opinions, or methods related to the following areas:

• Novel metabolic role

• Dynamics, including biogenesis, protein targeting, proliferation, protein degradation, organelle turnover

• Signalling and regulatory mechanisms

• Large-scale and data-driven approaches

• Interaction and crosstalk between these organelles

• Tissue and cell specificity

• Modeling and theoretical work

The submitted manuscript should provide significant biological advances in the field. Descriptive studies lacking such advances would be declined without peer review.


Keywords: plastids, chloroplast, peroxisome, mitochondria, metabolism, signaling, inter-organellar interaction


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.
