Figure 2.
Alignment of sequences flanking JLA regions in some basal angiosperms, Magnoliids, and eudicots (type I at position b, and type II at position e), and the sequences within the JLA in some monocots (type III at position f or g). Dashed lines denote gaps. Grey segments and the arrow lines above indicate coding regions and transcriptional directions of specified genes, respectively. (A) Grey box denotes degenerate rps19 genes (5' segment) found in the IRA of the type II (position e) pattern. (B) A degenerate rpl22 gene (boxed sequences) found in the IRA of type III (position g). "//" stands for abbreviated base pairs in the sequences of Oncidium and Dendrobium.
