苜蓿中华根瘤菌（Sinorhizobium meliloti）1021的IV型分泌系统（T4SS）是DNA接合转移所必需的。然而，它不是宿主入侵和持久性所必需的，不像密切相关的哺乳动物细胞内病原体的T4SS。在植物与动物宿主入侵的细菌T4SS的要求的比较表明，这些细菌占据的细胞内壁龛的重要差异。
The type IV secretion system (T4SS) of the plant intracellular symbiont Sinorhizobium meliloti 1021 is required for conjugal transfer of DNA. However, it is not required for host invasion and persistence, unlike the T4SSs of closely related mammalian intracellular pathogens. A comparison of the requirement for a bacterial T4SS in plant versus animal host invasion suggests an important difference in the intracellular niches occupied by these bacteria.
