Cloning and identification of CsKF1, CsKF2, and CsKF3 genes. (A) The full-length CDS of CsKF1, CsKF2, and CsKF3 were obtained by RT-PCR using specific primers designed according to the cucumber genome database. (B) Schematic diagram for the domain organization of CsKF1, CsKF2, and CsKF3 analysed in SMART (http://smart.embl-heidelberg.de/), indicating that these kinesins have putative kinesin motor domains in the central region. The truncated peptides CsKF1-N, CsKF2-C, and CsKF3-C for preparation of polyclonal antibodies are also indicated in the diagram. (C) Prediction of coiled-coils in CsKF1, CsKF2 and CsKF3 by COILS (http://www.ch.embnet.org/software/COILS_form.html). The x-axis represents the position of amino acid residues, and the y-axis represents the probability of the formation of coiled-coils. A probability value >0.5 indicates that the corresponding region most probably forms a coiled-coil.
