The Type VI Secretion System of Sinorhizobium fredii USDA257 Is Required for Successful Nodulation With Glycine max cv Pekin.

ABSTRACT: The symbiotic relationship between rhizobia and legumes is critical for sustainable agriculture and has important economic and environmental implications. In this intricate process, rhizobial bacteria colonise plant roots and induce the formation of specialised plant organs, the nodules. Within these structures, rhizobia fix environmental nitrogen into ammonia, significantly reducing the demand for synthetic fertilisers. Multiple bacterial secretion systems (TXSS, Type X Secretion System) are involved in establishing this symbiosis, with T3SS being the most studied. While the Type 6 Secretion System (T6SS) is known as a "nanoweapon" commonly used by diderm (formerly gram-negative) bacteria for inter-bacterial competition and potentially manipulating eukaryotic cells, its precise role in le
