“…The latter was resolved as a sister to the land plants with high support (karol et al 2001(karol et al , Mccourt et al 2004. Generally this sistership is in agreement with the hypotheses on evolution of morphological, ultrastructural and biochemical characters that accompanied the emergence of streptophyte algae from an aquatic habitat and the colonization of the land (GrahaM 1993, lewis & Mccourt 2004, Fig.…”

Conjugates (Zygnematophyceae) represent the most species-rich (ca. 4000 spp) algal lineage within the Streptophyta. Studies using various molecular markers have placed the class as one of the crown groups in Streptophyta and even suggested a close relationship between the zygnematophycean algae and land plants. Phenotypic diversity complicates systematics of the class and the relationships between its taxa remain poorly understood. Molecular phylogenetic analyses have established a number of clades in the class and revealed a disagreement between the traditional taxonomic structure of Zygnematophyceae and the pattern of phylogenetic relationships between the class members. in this paper, an overview of recent advances in our understanding of the phylogeny and classification of conjugating green algae is presented, with emphasis on the major clades established in the class, the clades' structure and polyphyly of some genera. We describe the areas of conflict and agreement between molecular phylogeny and traditional morphology-based taxonomy and stress that phenotypic characters provide little evidence for inferring relationships between taxa even at low taxonomic levels.

“…If extant, these green algae would be classed among the charophycean green algae (CGA) that include several thousand mostly freshwater species with diverse morphologies ranging from unicells to complex erect branching forms (Kenrick and Crane, 1997;Karol et al, 2001;McCourt et al, 2004;Becker and Marin, 2009). Their phylogenic position within the green plants means the CGA have a special significance for our understanding of the early origins of plant cell walls and they have already provided much valuable information.…”

“…It is generally recognized that the colonization of land by plants and their subsequent radiation and diversification are profoundly important episodes in the history of life, and it is reasonable to assume that cell walls have played crucial roles in this (Kenrick and Crane, 1997;Karol et al, 2001;McCourt et al, 2004). After all, cell walls are a defining feature of plants and make up much of the plant body.…”
