In most <i>Achnanthes</i> species studied, auxospore formation is accompanied by biparental sexual reproduction, but we found uniparental auxosporulation in <i>Achnanthes</i> cf. <i>subsessilis</i>. Auxosporulation appears to be apomictic and follows contraction of the contents of unpaired cells and then a mitotic division, which is normally acytokinetic: one nucleus aborts before the cell develops into an auxospore. Rarely, both daughter nuclei survive and cytokinesis produces two auxospores (two auxospores per mother cell is highly unusual in pennate diatoms); one may abort. Expansion of auxospores is not accompanied by deposition of a transverse perizonium, but a longitudinal perizonium is produced and consists of a wide central strip (structurally similar to the araphid valve) and at least one narrow lateral strip. This newly discovered asexual lineage in <i>Achnanthes</i> is discussed in relation to other reproductive systems found in the genus, and also in relation to the 'sex clock' hypothesis concerning the adaptive significance of the diatom life cycle. Brief information on chloroplast division and nuclear dynamics over the cell cycle is also presented.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Apomixis in <i>Achnanthes</i> (Bacillariophyceae); development of a model system for diatom reproductive biology","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Achnanthes; apomixis; auxosporulation; Bacillariophyceae; breeding","OtherDescriptors":null,"Notes":null,"AnaPub":2004,"MonPub":null,"DateUpdate":"2012-01-17","DateCreate":"2011-12-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000223982600010","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/0967026042000236445"},"refs":null,"anarec":{"AnaID":210892,"PubliDate":2004,"Pagination":"327-341","XtraPublOfAnaID":null,"ISBN":null,"Volume":"39","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42675,"SerRR":"European Journal of Phycology.
