About this Research Topic
As the global population continues to rise, the demand for agricultural productivity intensifies. However, the challenge is not just about increasing yields; it is about doing so sustainably under conditions of nutrient scarcity, particularly phosphorus (P) and nitrogen (N) deficiencies. These macronutrients are vital for plant growth, yet their availability is often limited, affecting crop yield and quality. Understanding how plants adapt to P and N starvation is crucial for developing strategies to improve nutrient use efficiency (NUE) and ensure food security. Phosphorus and nitrogen deficiencies trigger complex physiological and molecular responses in plants. These include alterations in root architecture, activation of nutrient transporters, and shifts in metabolic pathways to optimize nutrient uptake and utilization. Genes and signaling pathways related to NUE play a critical role in these adaptive responses.
This Research Topic invites contributions that shed light on the physiological, cellular, and molecular mechanisms underpinning plant responses to phosphorus and nitrogen starvation. We are particularly interested in studies that explore innovative genetic and biotechnological approaches to enhance plant resilience and nutrient use efficiency under these stress conditions. Key themes for this issue include, but are not limited to:
• Genetic and molecular bases of plant adaptation to phosphorus and nitrogen scarcity, focusing on nutrient sensing and signaling pathways.
• The role of root architecture and rhizosphere interactions in optimizing nutrient uptake under limited nutrient conditions.
• Omics-based approaches (genomics, transcriptomics, proteomics, metabolomics) to dissect the complex regulatory networks in plants responding to P and N starvation.
• Application of advanced gene editing techniques, such as CRISPR-Cas systems, to manipulate key genes involved in nutrient uptake and assimilation, thereby enhancing nutrient use efficiency.
• Development and use of innovative agronomic strategies, including slow-release fertilizers and nanotechnology-based solutions, to improve nutrient delivery and reduce environmental impact.
We welcome original research articles, reviews, and method papers that advance our understanding of plant responses to phosphorus and nitrogen starvation. We encourage submissions that go beyond describing physiological responses to also elucidate the genetic and molecular processes involved. Contributions should present novel findings that enrich the field of nutrient use efficiency, including mechanistic insights, innovative methodologies, and applications that can lead to the development of more resilient crop varieties and sustainable agricultural practices.
