Alignment of sequences showing homology with the CENP-B motif. The following plant centromeric sequences were included: pTS5 fromBeta procumbens (this paper), CCS1 from Brachypodium sylvaticum, RCS1 from Oryza sativa, BCS1 from Hordeum vulgare, and MCS1A from Zea mays (all taken fromAragon-Aclaide et al. 1996). (A) Nucleotides matching the CENP-B motif are shaded. (B) Cladogram representing the homology of plant centromeric sequences containing a region with similarity to the CENP-B consensus motif and the CENP-B sequence of the human alphoid DNA (Choo 1997).
