We will investigate the molecular evolution of the genes involved in the interaction between Lotus and its rhizobial symbiont. We will characterize the levels of nucleotide variation at two loci critical in the recognition of the bacterial symbiont, namely NFR1 and NFR5. In combination with evolutionary genetic analyses, infection assays will be conducted to determine the recognition phenotype between hosts and symbionts. Allelic variants from the wild and/or modified by site-direct mutagenesis will be transformed into the appropriate mutant lines to pinpoint the specific amino acid residues associated with inter-species recognition.

我们将研究参与荷花与其根瘤菌共生体相互作用的基因的分子进化。我们将描述对细菌共生体识别至关重要的两个位点（即NFR1和NFR5）的核苷酸变异水平。结合进化遗传分析，将进行感染分析，以确定宿主和共生体之间的识别表型。来自野生和/或通过位点直接诱变修饰的等位基因变异将转化为适当的突变系，以确定与种间识别相关的特定氨基酸残基。
