The occurrence and phylogenetic significance of a multilayered structure in Coleochaete spermatozoids
The structure of the spermatozoid of Coleochaete supports the hypothesis that this alga may be relatively close to the phylogenetic line which led directly to archegoniate plants.
The seta-bearing cells of Coleochaete scutata (Chlorophyceae, Chaetophorales)

Functional and evolutionary implications of seta-bearing cells of Coleochaete scutata have been studied with the light and electron microscopes.
Cytokinesis in the Green Alga Fritschiella

It is reasonable to assume that various cellular processes, including cytokinesis, were modified early in the evolution of the terrestrial plant cell from its ancestral green algal cell, and that these modifications were passed onto the land plants as well as to some modern green algae.
THE LIFE HISTORY OF COLEOCHAETE SCUTATA (CHLOROPHYCEAE) STUDIED BY A FEULGEN MICROSPECTROPHOTOMETRIC ANALYSIS OF THE DNA CYCLE 1, 2
The life history of Coleochaete scutata Bréb. was analyzed by Feulgen microspectrophotometry, a technique measuring DNA content in individual nuclei. By correlating nuclear DNA content with…
Isolation and partial characterization of a corynebacteriophage beta, tox operator constitutive-like mutant lysogen of Corynebacterium diphtheriae
The constitutive expression of diphtheria toxin was found to be cis dominant in the double lysogen C7(betacrm45+/betatoxct1+), consistent with the existence of a tox operator locus.
The totipotency and relationship of seta-bearing cells to thallus development in the Green Alga Coleochaete Scutata. A laser microbeam study.
MITOSIS AND CYTOKINESIS IN SESSILE SPORANGIUM OF TRENTEPOHLIA AUREA (CHLOROPHYCEAE) 1
An ultrastructure study of mitosis and cytokinesis in the sessile sporangium of Trentepohlia aurea (L.) Mart, was made to clarify the phylogenetic position of the alga. Mitosis was closed and centric…
THE ULTRASTRUCTURE OF MULTILAYERED STRUCTURES ASSOCIATED WITH FLAGELLAR BASES IN MOTILE CELLS OF TRENTEPOHLIA AUREA 1
The MLS of Trentepohlia aurea may represent a stage in the evolutionary development of the MLS of land plants and may be a useful character in phylogenetic studies.
A CLASSROOM DEMONSTRATION OF ZOOSPORE PRODUCTION IN THE GREEN ALGA SCHIZOMERIS LEIBLEINII KUETZ. 1 2
- G. McBride
- Environmental ScienceJournal of phycology
- 1 September 1968
Using the parenchymatous ulotrichalean green alga Schizomeris leibleinii, a dependable technique for the classroom demonstration of zoospore production is described. The onset of zoospore release can…
