Genetic interaction between RPS10B and CUC3 in organ separation. (a-f) Cauline vegetative nodes. cuc3 (GABI-KAT GK_302G09) nodes are phenotypically wild-type (compare a and d), with rare exceptions, as in e where a cuc3 accessory axillary bud (arrow) appeared to be fused with an axillary branch. rps10b-1 nodes occasionally show leaf-to-stem fusion (arrow in b) or the cauline leaf is missing (c), in addition to the lack of the axillary bud which was shown in Figure 2f,g. The upper of the two rps10b-1 cuc3 double mutant nodes in f shows leaf-to-stem fusion (arrow). The bottom node lacks the cauline leaf and the bottom of the axillary branch may be fused with the primary inflorescence.Scale bar in (f) for (a-f): 5 mm.
