Abstract
Rhizobium meliloti nod genes are required for the infection of alfalfa. Induction of the nodC gene depends on a chemical signal from alfalfa and on nodD gene expression. By using a nodC-lacZ fusion, we have shown that the induction of the R. meliloti nodC gene and the expression of nodD occur at almost normal levels in other Rhizobium backgrounds and in Agrobacterium tumefaciens, but not in Escherichia coli. Xanthomonas campestris, or Pseudomonas savastanoi. Our results suggest that bacterial genes in addition to nodDABC are required for nod gene response to plant cells. We have found that inducing activity is present in other plant species besides alfalfa. Acetosyringone, the A. tumefaciens vir gene inducer, does not induce nodC.
摘要
苜蓿中华根瘤菌的结瘤基因是苜蓿感染所必需的。nodC基因的诱导依赖于来自苜蓿的化学信号以及nodD基因的表达。通过使用nodC - lacZ融合体，我们已经表明，苜蓿中华根瘤菌nodC基因的诱导以及nodD的表达在其他根瘤菌背景和根癌农杆菌中几乎以正常水平发生，但在大肠杆菌、野油菜黄单胞菌或丁香假单胞菌中则不然。我们的结果表明，除了nodDABC之外，细菌基因对于结瘤基因对植物细胞的反应也是必需的。我们已经发现，除苜蓿外，其他植物物种中也存在诱导活性。根癌农杆菌vir基因诱导剂乙酰丁香酮不会诱导nodC。
