Top This article has been rated as Top-importance on the project's importance scale However, because of the diversity of soil bacteria, other species can be involved and can potentially be apart of the blue-green algae problem. Clayton 1990; Margulis and Schwartz 1988, Pr-12; 1998, Pr-17; Sleigh et al. The classification of the Phaeophyta has been reviewed by several authors in recent years, of whom Scagel (1966), Russell (1973), Wynne & Loiseaux (1976), Bold & Wynne (1978, 1985), Christensen (1980), Wynne (1981) and Clayton (1984) are noteworthy. Unit – I Classification and evolution of Algae Criteria used in the classification of algae (Bold and Wynne,1978). Multicellular, from branched filaments to massive and complex kelp; Because of their large size, the brown algae were long given their own division, the Phaeophyta, but they are clearly members of the heterokonts, and are clearly a comparable group to the other major heterokont groups. Salient features of major classes: Prochlorophyta, Chlorophyta, Charophyta, Xanthophyta, Phaeophyta and Rhodophyta. It can become weedy and totally cover the surface of small ponds and lakes. Algae are generally grouped into more than a dozen major groups, primarily on the basis of pigment composition, storage products, and a variety of ultrastructural features. algae. 8. PLANT BIODIVERSITY-I: ALGAE, FUNGI, LICHENS AND BRYOPHYTES Unit-I: ALGAE General trends and criteria for Algal classification (Bold and Wynne, 1978). They shifted Vaucheria to Xanthophyceae, based on the following charac­teristics: 1. New Jersey, Prentice-Hall, xiv+706 p. If you would like to participate, visit the project page. Phaeophyceae - the brown algae. Rippka et al., (1979) classify blue-green algae into five orders; Chroococcales Pleurocapsales, Nostocales, Oscillatoriales and Stigonematales. Life cycles of algae. Fritsch (1935, 1945) in his book “The Structure and Reproduction of the Algae” proposed a system of classification of algae. This group contains the largest number of divisions. The lineage of algae according to Thomas Cavalier-Smith. De Reviers and others published Towards a new classification of the brown algae | Find, read and cite all the research you need on ResearchGate Robert Edward Lee’s Classification (1989) CLASSIFICATION OF ALGAE PROPOSED BY F.E. (1957), Prescott (1969), Round (1973), Bold and Wynne (1978) separated Vaucheria from Chlorophyceae and placed it under the class Xanthophyceae. Blue-green algae associated with turf decline have been identified as Phormidium and Oscillatoria species (Tredway et al. Structure and Reproduction. He treated algae giving rank of division and divided it into 11 classes. Publications of Michael J. Wynne. Algae of uncertain position (i) Chloromonadales (ii) Cryptophyceae .

FRITSCH (1935) The most comprehensive and authorative classification of algae was given by F.E Fritsch (1935) in his book ‘The Structure and Reproduction of the Algae’. This view was supported by workers like Smith ,Papenfuss, Prescott. The Charophyta consists of single class Charophyceae; order Charales and family Characeae. Table 1 fea- tures one such classification scheme. Adding to this is a new species of red seaweed recently described by Michael Wynne of the University of Michigan, namely, Martensia incipiens, which was collected at Sadah, east of Salalah.He describes the new species in the journal, Phytotaxa, published Oct. 2, 2019. they are chiefly freshwater algae (mainly Chlorophytes) and are more closely related to the higher plants than other marine algae. This article is part of WikiProject Algae, which aims to improve Wikipedia's coverage of the photosynthetic organisms commonly called algae and related topics. Supporters of this view, considered the following criteria to their classification. Start This article has been rated as Start-Class on the project's quality scale. 1984; Dixon 1973; Bold and Wynne 1985; Van den Hoek et al.

In the following study, some blue-green alga was classified as mentioned in Alsrani et al, (2000) according to the system of classification recorded by Bold and Wynne (1985) as follows: Introduction to the algae, Prentice-Hall, Inc.New Jersey. 1966. De Reviers et al. (According to F. E. Fritsch’s classification) iii) Systems of classification of algae up to orders according to F. E. Fritsch, G. M. Smith, H. C. Bold, and W. J. Wynnae. Origin and evolution of sex in algae. 2009). A surprisingly rich diversity of marine algae (seaweeds) has been found for the Dhofar coast of Oman. Unequal length of flagella of antherozoids. Traditionally the red algae has been divided into two large groups: Bangiophyceae and Floridiophyceae (Sleigh et al. Hydrodictyon occurs in temperate to tropical regions (Wehr and Sheath 2003) and can be found in lakes, ponds, rice paddies, fish farms, slow-flowing streams, and irrigation ditches (Bold and Wynne 1985, Prescott 1978). Algae - Algae - Classification of algae: The classification of algae into taxonomic groups is based upon the same rules that are used for the classification of land plants, but the organization of groups of algae above the order level has changed substantially since 1960. Clinton J. Dawes In 1985, Bold and Wynne presented a very conservative classification scheme ; 2006). Taxonomy of the Phaeophyta has been somewhat chaotic as far as the ordinal structure of the phylum is concerned (e.g. The taxonomic classification of algae is still the source of some dis- agreement; Bold and Wynne (1985) summarize 14 such classifications, in addition to their own. PDF | On Jan 1, 1999, B. Phylogeny and interrelationships among algae. According to the second view, the algae is above the rank of a division. As per the literature on molecular biology, algae are understood to be a group of microorganisms that have independently acquired chloroplasts, that is, intracellular structures with their own photosynthesis mechanism (Gibbs, 1992).Nevertheless, some disagreement still prevails in the taxonomic classification of algae (Bold and Wynne, 1985). Chlorophyta is a division of green algae, informally called chlorophytes.The name is used in two very different senses so that care is needed to determine the use by a particular author.

Later Smith (1950) followed by Greenwood et al. So it should be divided into some divisions (=phyta) and then each division into one or more classes. Fritsch’s Classification of Algae: F.E. There are a small number of terrestrial species. 1985; Bold and Wynne 1985; Graham and Wilcox 2000) with 12 to 15 orders. Flagellation of Algae. Topics covered include classification, cellular and sub-cellular organization, morphology and growth, reproduction and life cycles, evolution, phylogeny, physiology, ecology and the relationship between algae and man. Summary Goniotrichum Kützing (1843) and Erythrotrichia Areschoug (1850), both being based on Conferva ceramicola Lyngbye (1819), must be regarded as nomenclatural synonyms. Chlorophyta is a division of green algae, informally called chlorophytes.The name is used in two very different senses, so care is needed to determine the use by a particular author.
