The capability of land plants to cope with changes in nutrient availability requires different levels of governance. The efficiency of this network represents a critical step for modulation of plant growth and development in response to various environmental conditions. In legume plants, this fine-tuned coordination and integration network is also finalized to the control of all the different steps of the symbiotic interaction with rhizobia leading to formation, development, and functioning of the N2-fixing nodules. External nitrogen (N) availability signal must be integrated by the perception of the plant internal N demand to elaborate the best-supporting strategy. In the same way, sensing of external and internal conditions is important to regulate long-distance signaling pathways for carbon allocation to the nodules. Furthermore, proper transport and distribution of micronutrients are crucial for the efficient nodulation activity.
This Research Topic welcomes Original Research, Reviews, Mini Reviews, and Opinion articles providing new insights into the characterization of factors involved in the local and systemic nutrient signaling pathways such as:
• transporters
• kinases/phosphatases
• transcription factors
• hormones
• calcium
• small peptides
Please note that descriptive studies, including those using 'omics approaches, defining gene families, or descriptive collections of transcripts, proteins, or metabolites will not be considered for review unless they are expanded and provide mechanistic and/or physiological insights into the symbiotic nitrogen fixation process.
