Analysis of the complete organellar genomes of the rockweed (Fucaceae, Phaeophyceae) supports its infraspecific recognition as var. .

L. is a broadly distributed monoecious intertidal seaweed. The specific status of however is debatable.

Porphyrins affect the self-assembly of tubulin in solution.

Self-assembly of tubulin heterodimers in solution has been studied in the past to predict the effects that ligands and/or conformational changes have on the formation of tubulin filaments. Self-assembly of tubulin in solution has produced formations similar to cellular microtubules (MTs). The present study reports on the effects that two porphyrins (protoporphyrin IX, PPIX and tetrakis(4-sulfonatophenyl)porphyrin, TPPS) produce on the self-assembly of tubulin alpha,beta-heterodimers in buffer solution.
