Figure 2. — SEM Showing the Effects of the uni Mutation on Leaf Primordium Initiation and Early Development.

(A) and (B) Two-week-old wild-type (JI 2171) vegetative shoot apices.

(C) and (D) Two-week-old sibling uni mutant (JI 2171) vegetative shoot apices. The white arrow in (C) indicates a central crease marking the beginning of lamina folding of a single, terminal leaflet.

A, shoot apex; P1 to P4, plastochron 1 to plastochron 4 of leaf development; S1 to S3, stipule primordia present on P1 to P3 marginal blastozones; L2 to L4, proximal leaflet primordia present on P2 to P4 marginal blastozones; T3 and T4, tendril primordia present on P3 and P4 marginal blastozones. .
