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: It is demonstrated that the Arabidopsis HAIRY MERISTEM (HAM) family of transcription regulators act as conserved interacting cofactors with WUS/WOX proteins, establishing a new framework for the control of stem cell production during plant development.

TL;DR: Arabidopsis mutants triply homozygous for knockout alleles in three Arabidopsis HAM orthologs exhibit loss of indeterminacy in both the shoot and root, which is fundamental to the generation of plant architecture and a central component of the plant life strategy.

TL;DR: The bodies of seed plants are comprised of two classes of organs with contrasting growth and symmetry attributes: stems and roots are indeterminate organs that exhibit apical growth at apical meristems and radial growth at the vascular cambium.

TL;DR: A pivotal finding in these studies is that the Au-protamine-DNA conjugates greatly stabilize the DNA; and DNA structure and vaccine activity are maintained even after exposure to physical, chemical, and temperature-accelerated degradation.
