The lupine (Lupinus luteus cv. Ventus) cDNA clones encoding homologues of cyclin (CycBlfi, CycBl;3, CycBl;4) have been Isolated from cDNA library prepared from roots inoculated with Bradyrhizobium lupint. Comparison of the deduced amino-acid sequences of CycBlg, CycBl;3, CycBl;4 and previously described CycBl;l (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 I of B-like mitotic cyclins.
