Ml. Flores et al., STUDIES ON THE SKELETAL CELL-WALL AND CUTICLE OF THE CYSTOCARPIC STAGE OF THE RED SEAWEED IRIDAEA-UNDULOSA BORY, Botanica marina, 40(5), 1997, pp. 411-419
The skeletal cell wall material isolated from cystocarpic thalli of Ir
idaea undulosa Bory contains an unusually high percentage of proteins
and/or glycoproteins and lesser amounts of polysaccharides. The polysa
ccharides are, possibly, cellulose, a (1-->4) linked mannan, a kappa/i
ota-carrageenan and an agaroid. The 'cuticle', an amorphous covering w
hich protects the thalli, shows a similar general composition.
