Hormogonia sense and respond to unidentified plant-derived chemical signals that attract and guide them towards the symbiotic tissues of the host. There is increasing evidence to suggest that their interaction with host plants is regulated by chemotaxis-related signal transduction systems. The genome of N. punctiforme contains multiple sets of chemotaxis (che)-like genes. In this study we characterize the large che5 locus of N. punctiforme. Disruption of NpR0248, which encodes a putative CheR methyltransferase, results in loss of motility and significantly impairs symbiotic competency with the liverwort Blasia pusilla when compared with the parent strain. Our results suggest that chemotaxis-like elements regulate hormogonia function and hence symbiotic competency in this system.
