TL;DR: This comparison reveals genomic changes concomitant with the evolutionary movement to land, including a general increase in gene family complexity; loss of genes associated with aquatic environments; acquisition of genes for tolerating terrestrial stresses; and the development of the auxin and abscisic acid signaling pathways for coordinating multicellular growth and dehydration response.

TL;DR: The genome sequence of the lycophyte Selaginella moellendorffii (Selaginella), the first nonseed vascular plant genome reported, is reported, finding that the transition from a gametophytes- to a sporophyte-dominated life cycle required far fewer new genes than the Transition from a non Seed vascular to a flowering plant.

TL;DR: Transcriptomic analysis of sexual reproductive structures reveals intricate control by TFs, activity of the ROS gene network, and the ancestral use of plant-like storage and stress protection proteins in the zygote.

TL;DR: A cellular network is emerging that links cytokinin activity to both developmental and physiological processes, and evidence has been provided that downstream signalling is transmitted through a His-to-Asp phospho-relay involving phosphotransmitter and response regulator proteins.

TL;DR: A modified model for cytokinin signaling is proposed in this article, which predicts the perception of the cytokinins signal at the plasma membrane by membrane-located sensor histidine kinases.
