Sequences of the gene encoding the large subunit of RUBISCO (rbcL) for 30 genera in the six currently recognized families of conjugating green algae (Desmidiaceae, Gonatozygaceae, Mesotaeniaceae, Peniaceae, and Zygnemataceae) were analyzed using maxi

Chlamyclomonas smithii sp. nov. is described from two strains of Chlamyclomonas originally isolated by Dr. Gilbert M. Smith. The mating types are inter-fertile with those of Chlamyclomonas reinhardtii (Culture No. 89 and 90) maintained in the Culture

Gonatozygon and Genicularia have been placed in various families within the conjugating green algae, and recent treatments place them in the order Desmidiales, in a separate family Gonatozygaceae or within the family Peniaceae. Nucleotide sequences o

Sequences for the Rubisco large subunit (rbcL) gene were used to test hypotheses about the evolution of chloroplast shape and thallus type in genera of two families of conjugating green algae (Zygnematales): the Mesotaeniaceae (saccoderm desmids, mos

The morphologically diverse green algae (Chlorophyta) include distinct, ancient lineages for which phylogenetic inference from morphological, ultrastructural, and biochemical characters has led to conflicting hypotheses. Cladistic analysis of ribosom

The chloroplast genome in Spirogyra maxima (Hassall) Kutzing is 130 kb in size and lacks large repeat units. The 16S and 23S rRNA genes are separated by approximately 44 kb, which makes co-transcription of these genes unlikely. Spirogyra maxima is un

Recent findings on the effects of polyploidy on morphology in filaments of the common green alga Spirogyra invalidate the reliance on several characters used to erect the 386 species described for this genus. Spontaneous ploidal changes have been obs

1. A chromosome count of n=ca. 44 is recorded for two strains of Cylindrocystis brebissonii (Nos. 1922 and 1923 from the Culture Collection of Algae at Indiana University).2. A complete mitosis of C. brebissonii was observed and is described along wi

A species complex in Spirogyra consists of the series of filament morphotypes of various ploidal levels arising from an original morphotype within a clonal culture or in nature. A clonal culture of filaments identified as Spirogyra maxima (Hassall) K

Zygospore-wall structure is described for nine species of Sirogonium using the light microscope and scanning electron microscopy (SEM) on spores from cultures and on glycerin-preserved spores from field collections. Zygospores possess four distinctiv
