BELOW THE SURFACE. "General appearance and size also belie very different tissue constructions and developmental capacities. The non-vascular blade-stipe-holdfast architecture of some marine brown algae is constructed with an intercalary meristem (e.g. Agarum and Macrocystis) and yet is remarkably similar to the leaf-stem-root configuration of the vascular land plants." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

ACELLULAR GIANTS. "Some acellular (siphonous) species, like those of Caulerpa, can attain body lengths in excess of 20 m and a general morphology strikingly reminiscent of the rhizomatous growth habit of the vascular land plant without benefit of multicellularity." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

ALGAL CLADES. "It is commonplace to find plants with filamentous, membranous, foliar, tubular, kelp-like, and coralline life forms in each of the red, green, and brown algal clades." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

LOOKS ARE DECEPTIVE. "However, it is strikingly evident that the general appearance, size, or growth form of plants cannot be used to distinguish the various lineages." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

GENESIS. "These and other criteria support the generally held view that each algal lineage traces its ancestry back to a unicellular ancestral organism, that colonial and multi-cellular life forms have evolved independently many times, that the land plants (embryophytes) and the charophycean algae share a last common ancestor, and that the embryophytes are a monophyletic group." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

MONGREL LOT. "Plants can be thus classified and sorted into different lineages based on molecular, cellular, or ultrastructural features." http://aob.oxfordjournals.org/content/85/4/411.full.pdf View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the theme of the evolution of plant body plans, which necessarily also considers plant developmental systems in true evo-devo style (evolution-development). Far from being arcane and abstract, this topic highlights the most useful aphorism in biology, that “nothing in biology makes sense except in the light of evolution.” (Theodosus Dobzansky, adapted from the Jesuit priest, Teilhard de Chardin). https://en.m.wikipedia.org/wiki/Nothing_in_Biology_Makes_Sense_Except_in_the_Light_of_Evolution View in LinkedIn

WIDESPREAD. “The ability to sense the geomagnetic field for use as a global reference during spatial orientation has been demonstrated in more than 30 species of vertebrates.” https://lnkd.in/etSP2df View in LinkedIn
