[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)。

[Abstract]  Bacterial glycoproteins are of increasing interest due to their abundance in nature and importance in health and infectious diseases. However, only a very small fraction of bacterial glycoproteins have been characterized and its post-translational modification machinery identified. While analysis of glycoproteins can be achieved through various techniques, this is often limited by the specific characteristics of individual proteins such as type and level of glycosylation. Lectins are sugar-binding proteins that recognize specific glycoconjugates in a manner similar to antigen-antibody ... [摘要]  细菌糖蛋白由于其在自然界中的丰富性和在健康和传染病中的重要性而日益受到关注。 然而,只有非常小部分的细菌糖蛋白已被表征和其翻译后修饰机制鉴定。 尽管通过各种技术可以实现糖蛋白的分析,但是这常常受到单个蛋白质的特定特征的限制,例如糖基化的类型和水平。 凝集素是以类似于抗原 - 抗体相互作用的方式识别特异性糖缀合物的糖结合蛋白。 在这里,我们描述了一种简单的方法使用基于凝集素的蛋白质印迹分析检测糖蛋白,这可以应用于不同的生物体,并与各种其他策略的补充分析。
