The pigment composition of the light-harvesting complexes isolated from several brown algae belonging to different orders has been analysed by reverse-phase HPLC. Relative to whole chloroplasts, they were markedly enriched in Chl c, fucoxanthin and violaxanthin and conversely depleted in Chl a. The relative molar proportions of the 4 main pigments (Chl a/Chl e/fucoxanthin/violaxanthin) ranged from 100:18:76:6 to 100:30:107:17. The protein moiety of LH complexes of all the species studied were composed of one or two main polypeptide components in the range of 19-22 kDa. Those polypeptide subunits were arranged in polymeric particles about 240 kDa in Laminaria saccharina. A polyclonal antibody raised against the LH polypeptide of Fucus serratus has been tested on LH apoproteins of other Chromophytes and Chlorophytes. Phylogenic inplications of these results discussed. © 1991.
