1. exo84b Mutants Have Cell Wall Stubs
exo84b Mutants Have Cell Wall Stubs.(A) to (C) FM4-64–stained abaxial 3rd leaf epidermis of wild-type (A), exo84b-1 (B), and exo84b-2 (C) seedlings.(D) to (G) FM4-64–stained abaxial leaf epidermal cells of exo84b-1 mutant plants.
exo84b Mutants Have Cell Wall Stubs.(A) to (C) FM4-64–stained abaxial 3rd leaf epidermis of wild-type (A), exo84b-1(B), and exo84b-2(C) seedlings.(D) to (G) FM4-64–stained abaxial leaf epidermal cells of exo84b-1 mutant plants. A single confocal section is shown in red (left) with corresponding three-dimensional reconstruction from serial confocal sections shown in white with the rotation indicated (arrow). Epidermal cells contained short cell wall stubs (asterisk) (D), long unfinished cell walls (triangle) ([D] and [E]), and aberrant cell plates (F).(G) Imperfectly separated guard cells with a developed stomatal pore. After the three-dimensional reconstruction, unfinished cell plate connected with the stomatal pore is evident. Bars = 10 μm.
