Quantitative assessment of hormogonia induction in Nostoc punctiforme by a fluorescent reporter strain.

ABSTRACT: While symbiotic plant-cyanobacteria interactions hold significant potential for revolutionizing agricultural practices by reducing the application of artificial nitrogen fertilizers, the genetic underpinnings of the symbiotic interaction between the plant host and the cyanobiont remain poorly understood. In particular, the molecular mechanisms through which host plants induce the formation of motile cyanobacterial filaments (hormogonia), essential for colonization and initiation of symbiosis, are not well characterized. In this study, we present a novel yet objective method for quantifying hormogonia induction, addressing limitations of traditional qualitative approaches. We have developed a reporter strain of Nostoc punctiforme PCC 73102 capable of quantifying hormogonia induction in resp
