特伦加中华根瘤菌金合欢生物变种ORS1073和根瘤菌属菌株ORS1001是两种亲缘关系较远的能使金合欢结瘤的菌株，它们产生相似的结瘤因子，这些结瘤因子被O-氨甲酰化、N-甲基化，且主要被硫酸化。

Sinorhizobium teranga bv. acaciae ORS1073 and Rhizobium sp. strain ORS1001, two distantly related Acacia-nodulating strains, produce similar Nod factors that are O carbamoylated, N methylated, and mainly sulfated.

Abstract

We have determined the structures of Nod factors produced by strains representative of Sinorhizobium teranga bv. acaciae and the so-called cluster U from the Rhizobium loti branch, two genetically different symbionts of particular Acacia species. Compounds from both strains were found to be similar, i.e., mainly sulfated, O carbamoylated, and N methylated, indicating a close relationship between host specificity and Nod factor structure, regardless of the taxonomy of the bacterial symbiont.

摘要

我们已经确定了代表特氏中华根瘤菌金合欢生物变种以及来自百脉根分支中所谓的U簇的菌株所产生的结瘤因子的结构，这两种菌株是特定金合欢物种的两种遗传上不同的共生体。发现来自这两种菌株的化合物相似，即主要是硫酸化、O-氨甲酰化和N-甲基化的，这表明宿主特异性与结瘤因子结构之间存在密切关系，而与细菌共生体的分类无关。
