Elymus and Macropidia, are which type of mutual multicellular organisms?
Elymus (plant) Elymus is a genus of perennial plants with approximately 150 species in the grass family, related to rye, wheat, and other widely grown cereal grains.
Planktothrix Planktothrix is a genus of filamentous cyanobacteria (often called blue-green algae). "P. agardhii" is regarded as a type species of the genus. Like all the Oscillatoriales, "Planktothrix" species have no heterocyst and no akinetes, but are unique because they are planktonic, solitary trichome and have gas vacuoles. Before the work of Suda et al., some species of the taxon were grouped within the genus "Oscillatoria". A tremendous body of work on "Planktothrix" ecology and physiology has been done by Anthony E. Walsby, and the 55.6 kb microcystin synthetase gene have been sequenced.
