title: Polyploidy in algae.
abstract: The green algae and the charophytes represent the most widely studied groups of algae in respect to their ploidy levels. In some genera increased size accompanies ploidy level changes as well as certain morphological modifications, but in other genera no evident obvious changes can be discerned. In the other major groups of algae, namely the Rhodophycophyta and Phaeophycophyta, few cases of polyploidy have been documented adequately. In the remaining groups, unusual nuclear phenomena and/or behavior have hampered studies and few species have adequately been studied in regard to their polidy levels.
