ABSTRACT The auxin signaling molecule regulates a range of plant growth and developmental processes. core transcriptional machinery responsible for auxin-mediated responses is conserved across all land plants. Genetic, physiological molecular exploration in bryophyte angiosperm model species have shown both qualitative quantitative differences responses. Given the highly divergent ontogeny dominant gametophyte (bryophytes) sporophyte (angiosperms) generations, however, it unclear whether such derive from distinct phylogeny or ontogeny. Here, we address this question by comparing physiological, to generations fern Ceratopteris richardii. We find that response gametophytes closely resembles thalloid bryophyte, whereas mimics flowering This resemblance manifests at phenotypic levels. Furthermore, show disrupting transport can lead ectopic induction on gametophyte, suggesting role alternation generations. Our study thus identifies phase, rather than phylogeny, as major determinant properties
