SEPTUM FORMATION IN THE GREEN ALGA ULOTHRIX PALUSALSA (CHLOROPHYTA, ULVOPHYCEAE)
Acta Botanica Neerlandica, 1987SUMMARY The ultrastructure of cell division, with the emphasis on septum formation, is described in the ulvophycean green alga Ulothrixpalusalsa Lokhorst. Septum formation involves a cleavage furrow which is initiated before the onset of mitosis. The development of the cleavage furrow is most pronounced at the final mitotic stages when it shows a ...

Ultrastructure and taxonomy of the genusEndophyton(Ulvales, Ulvophyceae)
European Journal of Phycology, 1997Fine structure of vegetative cells, development and morphology of sporangia and general morphology of zoospores were studied for the first time in the genus Endophyton Gardner. Vegetative cells contained one parietal perforate chloroplast with 2–4 ulvophycean pyrenoids and transverse cell walls without plasmodesmata. Sporangial walls were formed by two

New Ulvaceae (Ulvophyceae, Chlorophyta) from mesophotic ecosystems across the Hawaiian Archipelago
Journal of Phycology, 2016Ulvalean algae (Chlorophyta) are most commonly described from intertidal and shallow subtidal marine environments worldwide, but are less well known from mesophotic environments. Their morphological simplicity and phenotypic plasticity make accurate species determinations difficult, even at the generic level.

Cloning and characterization of nitrate reductase gene in Ulva prolifera (Ulvophyceae, Chlorophyta)
Journal of Phycology, 2017Ulva spp. dominates green tides around the world, which are occurring at an accelerated rate. The competitive nitrogen assimilation efficiency in Ulva is suggested to result in ecological success against other seaweeds. However, molecular characterization of genes involved in nitrogen assimilation has not been conducted.

Phylogenetic position of the Ulvophyceae and evolutionary relationships among its main lineages
2018The Ulvophyceae are currently regarded as one of the main classes of the Chlorophyta, but the relationship of the class with other classes of Chlorophyta is still a matter of debate. Also the relationship among ulvophyte lineages have been difficult to resolve, and in addition, monophyly of the class has been questioned.

Species diversity and phylogeny of the green macroalga Ulva (Ulvophyceae, Chlorophyta) in Singapore
PhytotaxaThe green macroalgal genus Ulva (Ulvaceae, Ulvophyceae, Chlorophyta) is commonly found in coastal ecosystems and confers many important marine ecological services. Despite prior research interest and recent advancements in Ulva taxonomy, in many parts of the world, its species diversity remains unresolved due to a high degree of morphological variation
