Directional Auxin Transport Mechanisms in Early Diverging Land Plants
The emergence and radiation of multicellular land plants was driven by crucial innovations to their body plans. The directional transport of the phytohormone auxin represents a key, plant-specific mechanism for polarization and patterning in complex seed plants. Here, we show that already in the early diverging land plant lineage, as exemplified by the moss Physcomitrella patens, auxin transpor...
متن کاملRSL genes are sufficient for rhizoid system development in early diverging land plants.
Land plants are anchored to their substratum from which essential inorganic nutrients are taken up. These functions are carried out by a system of rhizoids in early diverging groups of land plants, such as mosses, liverworts and hornworts. Physcomitrella patens RHD SIX-LIKE1 (PpRSL1) and PpRSL2 transcription factors are necessary for rhizoid development in mosses. Similar proteins, AtRHD6 and A...
متن کاملMultigene phylogeny of land plants with special reference to bryophytes and the earliest land plants.
A widely held view of land plant relationships places liverworts as the first branch of the land plant tree, whereas some molecular analyses and a cladistic study of morphological characters indicate that hornworts are the earliest land plants. To help resolve this conflict, we used parsimony and likelihood methods to analyze a 6, 095-character data set composed of four genes (chloroplast rbcL ...
متن کاملA special issue of Phytotaxa dedicated to Bryophytes: The closest living relatives of early land plants
The current issue of Phytotaxa is dedicated to a group of green land plants commonly referred to as bryophytes. A broad consensus confirms that bryophytes may not be monophyletic, but rather represent three paraphyletic lines, i.e., Marchantiophyta (liverworts, e.g., Fig. 1), Anthocerotophyta (hornworts, e.g., Fig. 2), and Bryophyta (mosses, e.g., Fig 3) (e.g., Mishler & Churchill 1984, Kenrick...
متن کاملThe microfossil record of early land plants.
Dispersed microfossils (spores and phytodebris) provide the earliest evidence for land plants. They are first reported from the Llanvirn (Mid-Ordovician). More or less identical assemblages occur from the Llanvirn (Mid-Ordovician) to the late Llandovery (Early Silurian), suggesting a period of relative stasis some 40 Myr in duration. Various lines of evidence suggest that these early dispersed ...
