natürliche-peptide NCR peptides, a fascinating class of nodule-specific cysteine-rich peptides (NCRs), play a pivotal role in the intricate symbiosis between legumes and nitrogen-fixing bacteria. These remarkable molecules, primarily studied in the context of Medicago truncatula, are not merely passive participants but active regulators, orchestrating the differentiation of bacteria into specialized forms essential for nutrient exchange. Their unique properties and diverse functions are shedding light on novel applications, from agricultural pest control to potential therapeutic agents.

At the heart of this symbiotic relationship lies the ability of NCR peptides to guide the differentiation of endocytosed bacteria into nitrogen-fixing bacteroids. This process is crucial for the plant to obtain vital nitrogen from the atmosphere, a capability that significantly enhances its growth and development.
