The green lineage (Viridiplantae) comprises the green algae and their descendants the land
plants, and is one of the major groups of oxygenic photosynthetic eukaryotes. Current …

The origin and early evolution of land plants in the mid-Palaeozoic era, between about 480
and 360 million years ago, was an important event in the history of life, with far-reaching …

▪ Abstract The Siluro-Devonian primary radiation of land biotas is the terrestrial equivalent of
the much-debated Cambrian “explosion” of marine faunas. Both show the hallmarks of …

Major differences in primary cell wall (PCW) components between non‐vascular plant taxa
are reported.(1) Xyloglucan: driselase digestion yielded isoprimeverose (the diagnostic …

A diverse array of molecular approaches is now available to the plant systematist for use in
phylogenetic inference, including restriction site analysis, comparative sequencing, analysis …

Sequences of the Internal Transcribed Spacer 2 (ITS-2) regions of the nuclear rDNA repeats
from 111 organisms of the family Volvocaceae (Chlorophyta) and unicellular organisms of …

Organisms show a remarkable range of sizes, yet the dimensions of a single cell rarely
exceed 100 µm. While the physical and biological origins of this constraint remain poorly …

The charophyte algae are six distinct groups of mostly freshwater green algae that are
related to modern land plants. Charophyte algae exhibit diverse morphologies and …

the presence of guanosine cofactor and magnesium ions. Comparative sequence analysis …

To study the evolutionary relationships among the four living gymnosperm orders and the
interfamilial relationships in each order, a set of 65 nuclear 18S rRNA sequences from ferns …
