The Origin of Land Plants: Some Answers, More Questions

Abstract: JSTOR is a not-for-profit service that helps scholars, researchers, and students discover, use, and build upon a wide range of content in a trusted digital archive. We use information technology and tools to increase productivity and facilitate new forms of scholarship. For more information about JSTOR, please contact support@jstor.org.. International Association for Plant Taxonomy (IAPT) is collaborating with JSTOR to digitize, preserve and extend access to Taxon. SummaryThe discovery of new fossil plant rema… Show more

“…Cuticle evolution would be critical during this landmark transition from aquatic to terrestrial habitats (Riederer, 2006). Indeed, there is fossil evidence (Taylor, 1988) and both chemical and/or anatomical evidence of a cuticle in the earliest nonvascular land plants, including Sphagnum species, Physcomitrella patens (mosses; Cook and Graham, 1998), and Asterella species (liverworts; Caldicott and Eglinton, 1976). This early association to the sn-2-GPAT family is clearly observed at the molecular genetic level by the appearance of strong homologs (E , 10 2100 ) to sn-2-specific GPATs in the genomes of P. patens and the lycopod Selaginella moellendorffii.…”

“…Less parsimonious hypotheses recognize bryophyte monophyly and either a sister group relationship with vascular plants (66) or an origin from within basal vascular plants (32,48,62,132). Phylogenetic evidence suggests that "bryophytes"' in general, and liverwort-like plants in particular, should have been important components of early terrestrial floras (67).…”

“…6,21,40,57,69,70,90,95,117,124,132) have either explicitly or implicitly identified one or more key innovations as crucial to the success of a particular taxonomic group. A bona fide key innovation should be a synapomorphy that was acquired immediately prior to an equally bona fide evolutionary radiation and can be shown to have been a far greater stimulus to that radiation than any other synapomorphies acquired on the same phylogenetic branch.…”
