Figure \(\PageIndex{7}\): All stages of the Polysiphonia life cycle have the same basic morphology. If you were to see them without magnification, they would all look more or less like this: a small, red, finely branching thallus. THE GENUS Polysiphonia The genus Polysiphonia, established by Greville in 1824, belongs to the family Rho domelaceae in the Rhodophyta. According to Falkenberg (1901), Polysiphonia should include all those radial1y symmetrical members of the Rhodomelaceae in which (1) at least the ulti mate branches are evidently polysiphonous, (2) The Genus Polysiphonia Greville (Ceramiales, Rhodophyta) in Kalegauk Island, Myanmar Journal of Aquatic Science and Marine Biology V1 I4 2018 3 Polysiphonia atlantica Kapraun & Norris Figure2.

Myung Sook Kim, In Kyu Lee. The Research Institute for 31 May 2014 Morphological characteristics and rbcL sequence analyses support the taxonomic placement of P. ul- leungensis within Polysiphonia sensu The parasitic members show great reduction in their size and pigmentation. • Some parasitic members are Ceramium condicola on Codium fragile, Polysiphonia The cell wall is two layered. The outer layer consists of pectic substances and the layer next to protoplast of cellulose. The protoplasm of the cell is highly viscous.

• Polysiphonia is heterothallic or dioecious – the male sex organs and the female sex organs are borne on different gametophytes. • Male gametophyte produces male sex organ Spermatangium • Female gametophyte produces female sex organ Carpogonium.

Reproduction in Polysiphonia: Polysiphonia … This paper presents a detailed study of the genus Polysiphonia sensu lato occurring at São Paulo and Espirito Santo States, Brazil, and an assessment of its morphological characteristics taking wide range of diagnostic morphological characteristics, the genus Neosiphonia was separated from Polysiphonia (Kim and Lee 1999). On the other hand, recent phyloge-netic studies have shown that Polysiphonia sensu lato in-cludes a heterogeneous group of genera: Boergeseniella Kylin, Bryocladia F. Schmitz in Engler et Prantl, Enelit- We performed an exhaustive survey of algal assemblages inside and outside the territories of five damselfish species around the Ryukyu Islands, Japan, using molecular and morphological characteristics.

Polysiphonia sp. 1 grew exclusively inside the farms of S. nigricans, and never elsewhere.

Since only Polysiphonia sp. 1 is harvested and consumed by the damselfish as a staple food, this interdependent relationship is an obligate cultivation mutualism. This is the first record of an obligate plant–herbivore cultivation mutualism in a marine The Rhodomelaceae differ from other Ceramiales families by the formation of pericentral cells in an alternating fashion.

These are non-pigmented, tapering, hair-like cells at the apices. Are Phycoerythrin-phycocyanin aggregates and phycoerythrin aggregates showing special spectral characteristics were prepared from the partly dissociated products of phycobilisomes from Polysiphonia urceolata.
