LOW MOLECULAR WEIGHT CARBOHYDRATES OF THE BANGIOPHYCIDAE (RHODOPHYTA)1

In the order Porphyridiales there are three clades based on molecular evidence. These show parallels with the low molecular weight carbohydrate (LMWCs) in different genera. Clade Porphyridiales 1 includes Dixoniella , Glaucosphaera , Rhodella , and one undescribed genus (3987) that all contain mannitol. Clade Porphyridiales 2 comprises taxa of the Stylonematales Rhodosorus and Stylonema species and contains digeneaside and sorbitol, whereas...
