	Stramenopiles
		A number of supposed stramenopiles are thought (opalines) or known (diatoms) to have lost the hairs.
		The stramenopiles is a very major grouping of eukaryotes containing some organisms with the largest linear dimensions known in the eukaryotic world (brown algae), as well as ecologically very important organisms - such as the diatoms.

		Stramenopiles are a "crown" taxon that evolved about 300 million years ago and radiated after the Cretaceous Period.
		The stramenopiles represent a major eukaryotic group that is taxonomically distinct from the chlorophytic or rhodophytic lineages of autotrophs.
		They carry their own genome that encodes for many (but not all) of the genes essential for photosynthesis.

	Stramenopiles
		Unlike the fungi, all members of the group have mitochondria with tubular cristae and synthesize lysine via the diaminopimelic acid pathway.
		The stramenopiles (Kingdom Stramenopila) that were previously included in the fungi and that have a way of life like the fungi are the
		The organisms in the above tree are called Stramenopiles (sometimes straminipiles).

	Stramenopiles
		Stramenopiles are a diverse group of eukaryotic organisms grouped together largely on the basis of recent molecular studies.
		Stramenopiles include the water molds (Division Oomycota), the golden algae (Division Chrysophyta), the diatoms (Phylum Bacillariophyta), the brown algae (Division Phaeophyta), and several other groups of organisms.
		Stramenopiles are a group based mainly on molecular studies and include the water molds, golden algae, diatoms, and brown algae, to name a few.

	Stramenopile
		The stramenopiles are one of the main groups of eukaryotes, including the giant multicellular brown algae, the planktonic diatoms, and most other algae of similar pigmentation, as well as similar flagellates, the fungus-like water molds and other colorless forms.
		Similar chloroplasts are found among the haptophytes and cryptomonads, and these are sometimes supposed to share a common coloured ancestor with the stramenopiles, in which case they may be grouped as the chromists.
		The stramenopiles are usually included among the Protista, but newer classifications often treat them in their own kingdom, called the Chromista or Stramenopila.

	Heterokont - Biocrawler (Site not responding. Last check: )
		The heterokonts or stramenopiles are a major line of eukaryotes.
		Most are algae, ranging from the giant multicellular kelp to the unicellular diatoms, which are a primary component of plankton.
		Patterson named this extended group the stramenopiles, characterized by the presence of tripartite mastigonemes, mitochondria with tubular cristae, and open mitosis.

		The stramenopiles refers to those protists which have tubular tripartite hairs on the body or flagella, or are derived from such organisms (Patterson, 1989).
		There is still some debate as to whether the first stramenopiles had chloroplasts or not, but most recent molecular trees (Leipe et al., 1994, 1997; Williams, 1991) place aplastidic taxa at the base of the tree.
		As the bicosoecids typically fall to the base of the stramenopile tree, and as Caecitellus and the pseudodendromonads have no tripartite hairs, it is possible that these additional taxa may form the sister group to the stramenopiles rather than be a part of the stramenopiles.

	Protista - Basal protista, Alveolates, Stramenopiles, Red algae, Green algae
		Alveolates include dinoflagellates, aquatic forms with two flagella and a cell wall made of armorlike cellulose plates; Paramecium and other familiar ciliates; and the Apicomplexa, a group of intracellular parasites that includes Plasmodium, the cause of malaria, and Toxoplasma, the cause of toxoplasmosis.
		Stramenopiles include water molds, golden and brown algae, and diatoms.
		The funguslike water molds (oomycetes) live in fresh water and soil, feeding on living or decaying organisms.

		However they are not actually related to them, and show a number of important differences, such as having diploid nuclei in their vegetative state and lacking chitin within their cell walls.
		One characteristic that water molds show in common with other stramenopiles is the typical heterokont pattern found in flagellate cells.
		The water molds include a number of important parasites, including the potato blight, which was a major cause of the Irish potato famine.

		Novel marine stramenopiles, identified by 18S ribosomal DNA sequences within the basal part of the stramenopile radiation but unrelated to any previously known group, constituted one of the most important novel lineages in these open-sea samples.
		Novel stramenopiles were found in all major habitats, generally accounting for a significant proportion of clones in genetic libraries.
		We specifically identified four clusters that were well represented in most marine surface waters (together they accounted for 74% of the novel stramenopile clones) and are the obvious targets for future research.
