Although sequences of many members of the stress-70 family are available, few genes from the Protoctista have been sequenced to date. Phylogenetic analyses of algae based on various molecules have not, as yet, provided clear results concerning relationships between major divisions. We cloned and sequenced several algal stress-70 genes in order to provide additional data and to further analyse phylogenetic relationships among algal divisions. New nuclear sequences were obtained from <i>Guillardia theta</i> (Cryptophyta), <i>Ascophyllum nodosum</i> (Heterokontophyta) and <i>Cyanophora paradoxa</i> (Glaucocystophyta). Phylogenetic trees of the stress-70 protein family calculated using different methods are presented. In our trees, the heterokont alga <i>Ascophyllum nodosum</i> is closely related to the slime mould <i>Dictyostelium discoideum</i>, while the nucleomorph (eukaryotic endosymbiont) of the cryptophyte <i>Rhodomonas salina</i> seems to be related to the chlorobiont lineage. The glaucocystophyte <i>Cyanophora paradoxa</i> and the nuclear sequence (host) of the cryptomonad alga <i>Guillardia theta</i> also seem to be closely related. The Cryptophyta and the heterokont algae have evolved from different secondary endosymbiotic events involving different hosts and probably different endosymbionts. However, until more stress-70 sequences of algal divisions become available no definitive conclusions can be drawn concerning branching of the major divisions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Molecular phylogeny of the stress-70 protein family with reference to algal relationships","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-15 01:32:43.116919","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"algae; molecular chaperone; molecular phylogeny; stress-70","OtherDescriptors":null,"Notes":null,"AnaPub":1997,"MonPub":null,"DateUpdate":"2022-04-13","DateCreate":"2016-10-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1997XX88000006","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/09670269710001737199"},"refs":null,"anarec":{"AnaID":261860,"PubliDate":1997,"Pagination":"279-285","XtraPublOfAnaID":null,"ISBN":null,"Volume":"32","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42675,"SerRR":"European Journal of Phycology.
