Vanadium-dependent haloperoxidase activity and phlorotannin incorporation into the cell wall during early embryogenesis of Fucus vesiculosus (Phaeophyceae)

Figures & data

Fig. 1. Specific bromo- and iodoperoxidase activity in eggs, zygotes (1 h to 12 h) and embryos (1 day to 9 days) of Fucus vesiculosus during 9 days after fertilization. h, hours; d, days. Bars are means ± SD.

Fig. 2. Hydrogen peroxide content in eggs, zygotes (1 h to 12 h) and embryos (1 day to 9 days) of Fucus vesiculosus during 9 days after fertilization. h, hours; d, days. Bars represent means  ± SD.

Fig. 3. Content of intracellular (a) and cell wall (b) phlorotannins in eggs, zygotes (1 h to 12 h) and embryos (1 day to 9 days) of Fucus vesiculosus during nine days after fertilization. h, hours; d, days. Bars represent means  ± SD.

Fig. 4. Scheme of putative metabolic links between low molecular weight phlorotannins in eggs, zygotes (1 h to 12 h) and embryos (1 day to 9 days) of Fucus vesiculosus. h, hours; d, days. Bars represent means  ± SD. Arbitrary units are normalized peak areas. Trimers may be triphlorethols, trifucols or trifuhalols.
