The term “heterokont” refers either to the flagellar arrangement of biflagellate cells in which the two flagella differ in length (as in anisokonts), type of motion, or ornamentation, or to those organisms (and organisms evolutionarily derived from such lineages) in which biflagellate cells with heterokont flagella are produced at some point during their life cycle. Stramenopiles: chromophytes from a protistological perspective. [14] The current consensus is that the ancestral stramenopiles / heterokonts were heterophic and acquired chloroplats after their defining feature (the triparite hairs) appeared.

Rather than continue to use a name whose meaning had changed over time and was hence ambiguous, the name 'stramenopile' was introduced to refer to the clade of protists that had tripartite stiff (usually flagellar) hairs and all their descendents. Their composition has been essentially stable, but their use within ranked systems varies. This led to hypotheses that all organisms with chlorophylla/c containing chloroplasts have a common phylogenetic history with cryptomonads, and should be taxopnomically grouped as the Chromista. The chloroplasts characteristically contain chlorophyll a and chlorophyll c, and usually the accessory pigment fucoxanthin, giving them a golden-brown or brownish-green colour. The term 'Stramenopile' was introduced in 1989 by Patterson [12] to overcome ambiguities that had (and continue to be) developed with the use of the term 'heterokont'.

Rigorous comparisons between diverse and between more closely related taxa are required. — heteromorphic, adj. Over time, the scope of application has changed; especially when in the 1970's as ultrastructural studies revealed greater diversity among the algae with chromoplasts (= chlorophylls a and c) than had previously been recognized. • Ochrophytes have heterokont flagellated cells with two different flagella, an anterior tinsel (mastigonemes) and posterior whiplash (smooth) flagellum (Fig. The second membrane presents a barrier between the lumen of the cER and the primary endosymbiont or chloroplast, which represents the next two membranes, within which the thylakoid membranes are found. The discovery that oomycetes and hyphochytrids are related to these algae, rather than fungi, as previously thought, has led many authors to include these two groups among the heterokonts. Originally, the heterokont algae was used only for Xanthophytes.

Many heterokonts are algae with chloroplasts surrounded by four membranes, which are counted from the outermost to the innermost membrane. This arrangement of membranes has led top hypothesis that heterokont chloroplasts were obtained from the reduction of a symbiotic red algal eukaryote, which had arisen by evolutionary divergence from the monophyletic primary endosymbiotic ancestor that is thought to have given rise to all eukaryotic photoautotrophs. Characterisation of Stramenopile-specific mastigoneme proteins in Phytophthora parasitica.

What is the meaning of heterokont? those having anterior flagella with stiff hairs). This suggests that they diverged before the acquisition of chloroplasts within the group. Molecular studies confirm that the genes that code for the proteins of these hairs are exc;lusive to stramenopiles. One consequence was that an array of heterotrophic organisms, many of which had not been previously considered as 'heterokonts' were seen as being related to the 'core heterokonts' (i.e. Meaning of heterokont.

Patterson named this extended group the stramenopiles, characterized by the presence of tripartite mastigonemes, mitochondria with tubular cristae, and open mitosis. 1. the quality of differing in form from the standard or norm. Any of numerous mostly aquatic organisms in the group Heterokonta, having zoospores or other swimming cells usually with a pair of flagella, one of which has brush-like extensions, and whose photosynthetic members have a distinctive form of chlorophyll. treat the diatoms as a division. This is not universal, however; Round et al. Heteronomous definition is - subject to external controls and impositions. isokont Having flagella of equal length. When the hairy flagellum beats, the stiff mastigonemes are forced backwards and this creates a retrograde current, pulling the cell through the water or bringing in food. In: Green, J.C., Leadbeater, B.S.C. An example is: In this scheme, the Chrysophyceae is conceived of a very extensive group (Chrysophyte sensu lato) that was paraphyletic - as the diatoms and brown algae evolved from within the chrysophytes. Menu. Definition of heterogeny. The anterior flagellum is covered with one or two rows of lateral hairs or mastigonemes, which are tripartite (i.e. The name Heterokonta can be confused with the (much older) name Heterokontae, which is generally equivalent to the Xanthophyceae, a limited subset of the Heterokonta.
