费氏中华根瘤菌(Sinorhizobium(Ensfer)fredii)是一种根瘤菌，具有广泛的结瘤寄主范围。因此，费氏链霉菌能够有效地使数十种不同的豆类植物结瘤，包括形成确定根瘤的植物，如重要的农作物大豆和豌豆，以及形成不确定根瘤的植物，如甘草和木豆。这种对不同共生的适应能力使得对弗氏链球菌产生的分子信号的研究越来越引起人们的兴趣，因为它允许分析它们在不同类型的根瘤中的共生作用。在这篇综述中，我们深入分析了不同的弗氏链霉菌分子在共生中的作用，包括结瘤因子，不同的表面多糖(胞外多糖、脂多糖、环状葡聚糖和K抗原被膜多糖)，以及通过共生型3型分泌系统传递到宿主细胞内部的效应物。
Sinorhizobium (Ensifer) fredii (S. fredii) is a rhizobial species exhibiting a remarkably broad nodulation host-range. Thus, S. fredii is able to effectively nodulate dozens of different legumes, including plants forming determinate nodules, such as the important crops soybean and cowpea, and plants forming indeterminate nodules, such as Glycyrrhiza uralensis and pigeon-pea. This capacity of adaptation to different symbioses makes the study of the molecular signals produced by S. fredii strains of increasing interest since it allows the analysis of their symbiotic role in different types of nodule. In this review, we analyze in depth different S. fredii molecules that act as signals in symbiosis, including nodulation factors, different surface polysaccharides (exopolysaccharides, lipopolysaccharides, cyclic glucans, and K-antigen capsular polysaccharides), and effectors delivered to the interior of the host cells through a symbiotic type 3 secretion system.
