Abstract

The NodD1 regulon of Sinorhizobium meliloti was determined through the analysis of the S. meliloti transcriptome in response to the plant flavone luteolin and the overexpression of nodD1. Nine new genes regulated by both NodD1 and luteolin were identified, demonstrating that NodD1 controls few functions behind nodulation in S. meliloti.

摘要

通过分析苜蓿中华根瘤菌转录组对植物黄酮木犀草素的响应以及nodD1的过表达，确定了苜蓿中华根瘤菌的NodD1调控子。鉴定出9个受NodD1和木犀草素共同调控的新基因，这表明NodD1在苜蓿中华根瘤菌结瘤背后控制的功能较少。
