The cyanobacterial tRNA(Leu) (UAA) intron: evolutionary patterns in a genetic marker.

Molecular biology and evolution - 1 Jun 2002

Costa José-Luis, Paulsrud Per, Lindblad Peter

Abstract excerpt

Cyanobacterial tRNA(Leu) (UAA) intron sequences from natural populations of Nostoc and other cyanobacteria were compared. Variation between the different introns was not randomly distributed but strongly restricted by the secondary and tertiary structure of the intron. Although all Nostoc sequences examined shared high similarity, differences were observed in one stem-loop. This stem-loop could be divided into...
