Journal Article
The molecular network governing nodule organogenesis and infection in the model legume Lotus japonicus
2010
Overview
Bacterial infection of interior tissues of legume root nodules is controlled at the epidermal cell layer and is closely coordinated with progressing organ development. Using spontaneous nodulating
Lotus japonicus
plant mutants to uncouple nodule organogenesis from infection, we have determined the role of 16 genes in these two developmental processes. We show that host-encoded mechanisms control three alternative entry processes operating in the epidermis, the root cortex and at the single cell level. Single cell infection did not involve the formation of trans-cellular infection threads and was independent of host Nod-factor receptors and bacterial Nod-factor signals. In contrast, Nod-factor perception was required for epidermal root hair infection threads, whereas primary signal transduction genes preceding the secondary Ca

oscillations have an indirect role. We provide support for the origin of rhizobial infection through direct intercellular epidermal invasion and subsequent evolution of crack entry and root hair invasions observed in most extant legumes.
Plant and bacteria symbiosis in some species results in the coordinate formation of nitrogen fixing nodules and infection of the plant host. Using mutant
Lotus japonicus
plants, Madsen and colleagues have determined the role of 16 different genes in these two processes.
