Figure 2. proCYC1At::CDB::GUS expression in hyd/fk seedlings.

A: Wild-type hypocotyl-cotyledon junction, 3 dpg; bar  = 100 µm. B: Wild-type leaf primordia, 7 dpg; bar  = 100 µm. C: Wild-type cotyledon epidermis, 7dpg; bar  = 50 µm. D: fk^hyd2 hypocotyl-cotyledon junction, 3 dpg. Arrow indicates ectopic cell division events in hypocotyl and cotyledon; bar  = 100 µm. E: fk^hyd2 hypocotyl-cotyledon junction, 7 dpg. Arrows indicate ectopic cell division events in hypocotyl and cotyledon; bar  = 200 µm. F: hyd1 hypocotyl-cotyledon junction, 3 dpg. Arrow indicates ectopic cell division events in hypocotyl; bar  = 100 µm. G; hyd1 hypocotyl-cotyledon junction, 7 dpg. Arrows indicate ectopic cell division events in hypocotyl and cotyledon; bar  = 200 µm. H, I: fk^hyd2 cotyledons at 7 dpg, showing expression in proximity to dissociated or disjunct xylem vessels; bar  = 50 µm. J: Wild-type hypocotyl region of a 3 dpg seedling, showing expression restricted to stomatal precursors of the cotyledon epidermis and the developing first pair of true leaves; bar  = 100 µm. K: fk^hyd2 hypocotyl (3 dpg) showing expression in association with the hypocotyl stele (arrow); bar  = 100 µm. L: fk^hyd2 hypocotyl epidermis (3 dpg) showing mis-oriented ectopic cell division event spanning two longitudinal cell files; bar  = 50 µm.
