| Popis: | The evolution of land plants from a charophycean algal ancestor was accompanied by an increased diversity of regulatory networks, including signaling pathways mediating cellular communication within plants and between plants and the environment. Canonical land plant hormone signaling pathways were originally identified in angiosperms, and comparative studies in basal taxa show that they have been assembled from both ancient and newly evolved components, both before and during land plant evolution. In this review we present our current understanding, and highlight several uncertainties, of the evolution of hormone signaling pathways, focusing on the biosynthetic pathways generating putative ligands and the downstream perception and signaling pathways often leading to transcriptional responses. |
