Zusammenfassung
Die molekularbiologischen Untersuchungen von Böden mithilfe von 16S-rRNA und 16S-rRNA-Gensequenzen haben sowohl zu erweiterten Kenntnissen von Phyla mit beschriebenen Arten als auch zu mehreren neuen Phyla unter den Prokaryoten geführt. Nach dem aktuellen Erkenntnisstand gibt es insgesamt mindestens 50 selbständige Phyla von Prokaryoten, 26 davon sind zurzeit in Bergey’s Manual of Systematic Bacte riology: Taxonomic outline of the prokaryotes, 2. Aufl., Ausgabe 6.0 (2005) aufgeführt (Garrity et al. 2005; Tabelle 4.2). Die restlichen 24 Phyla bestehen ausschließlich aus neuen, weitgehend unbekannten 16S-rRNA-Gensequenzen und haben infolgedessen allenfalls einen vorläufigen Status. Für die Anerkennung von Taxa-Namen oberhalb der Klasse gibt es noch keine offiziellen Regeln, was die Heterogenität der Bezeichnungen erklärt (Tabelle 4.2).
