FIG. 4.
Sequence analysis of the XRIC element. (A) Palindromic structure (ΔG = −44.9 kcal/mol) of the orf3 (X. oryzae pv. oryzae) XRIC element as predicted by using SeqWeb software (see Materials and Methods). (B) Nucleotide alignment of the XRIC elements found in the database by using MULTALIN software. The capital and lowercase letters in the consensus sequence indicate >80 and >50% consensus, respectively. A flanking gene (either 5′ or 3′) and the name of the organism are mentioned for each element. Xoo, X. oryzae pv. oryzae; Xcc, X. campestris pv. campestris. The GenBank accession numbers of the sequences, from top to bottom, are AY010120, AY010120, AB045312, AF302775, U19896, AB045311, AF329697, AF360374, and AF303107.
