The lupine (Lupinus luteus cv. Ventus) cDNA clones encoding homologues of cyclin (CycB1;2, CycB1;3, CycB1;4) have been isolated from cDNA library prepared from roots inoculated with Bradyrhizobium lupini. Comparison of the deduced amino-acid sequences of CycB1;2, CycB1;3, CycB1;4 and previously described CycB1;1 (Deckert et al. 1996, Biochimie 78, 90-94) showed that they share 46-65% of identical amino acids. The presence of conserved residues (Renaudin et. al., in The Plant Cell Cycle, in the press; Renaudin et al., Plant Mol. Biol, in the press) along with phylogenetic analysis of known plant cyclins revealed that the four lupine sequences belong to subgroup 1 of B-like mitotic cyclins.
