Nucleotide sequence alignments of full-length ITSs of the eight Leptolyngbya strains (six catacomb strains and strains LLi 18 and CCALA 094). The conserved (D1, D1′, D2, D3, D4, and D5) and variable (V2 and V3) domains, the antiterminator (box B and box A), and the tRNAIle and tRNAAla genes are indicated. One hundred percent sequence identity is indicated in grey within the conserved domains and is shaded within the variable regions.
