[Abstract]  Rhizobia interact symbiotically with legumes to form root nodules, where by rhizobia fix atmospheric dinitrogen into ammonia in exchange for carbon produced via photosynthesis. The symbiotic interaction is agriculturally important by reducing the need for fertilizer containing nitrogen. The root and stem nodule bacteria commonly include bacteria in the genera Rhizobium, Mesorhizobium, Sinorhizobium (Ensifer), and Bradyrhizobium, although other genera of bacteria have now been shown to form root nodule symbioses with several legume species (Weir, 2012). ... [摘要]  根瘤菌与豆科植物共生相互作用形成根瘤,其中根瘤菌将大气氮固定为氨,以交换通过光合作用产生的碳。共生相互作用在农业上是重要的,通过减少对含氮肥的需要。根和茎结节细菌通常包括根瘤菌属,中生根瘤菌,中华根瘤菌属( Ensifer )和 Bradyrhizobium >,虽然其他属的细菌现在已经显示形成根瘤与多种豆科物种的共生(Weir,2012)。不同的根瘤菌菌株在特定豆科植物品种(或品种)上形成不同数目的结节,并且每种根瘤菌菌株的氮固定效率,其固定氮并将其转移到植物的能力也是高度可变的(Toro,1996)。一些天然根瘤菌在固氮但在所生长的植物中形成大多数结节方面无效。这被称为结瘤问题的竞争(Triplett和Sadowsky,1992)。当评估大量不同的天然菌株时,竞争研究是不可行的。然而,单个菌株的结瘤速度与总体竞争性良好相关,并且可用于鉴定克服竞争问题的天然菌株(De Oliveira和Graham,1990; Bhuvaneswari等人,1980)。
