CopG, a Novel Transcriptional Regulator Affecting Symbiosis in sp. SUTN9-2.

The symbiotic interaction between leguminous and sp. SUTN9-2 mainly relies on the nodulation process through Nod factors (NFs), while the type IV secretion system (T4SS) acts as an alternative pathway in this symbiosis. Two copies of T4SS (T4SS and T4SS) are located on the chromosome of SUTN9-2.

The Type IV Secretion System (T4SS) Mediates Symbiosis between sp. SUTN9-2 and Legumes.

There has been little study of the type IV secretion system (T4SS) of bradyrhizobia and its role in legume symbiosis. Therefore, broad host range sp. SUTN9-2 was selected for study.
