Leaf morphology phenotypes of the gl1, CA1 and CA1; gl1 double mutant plants, and the illustration of the crossing procedure. (A) A 5-week-old Col wild-type plant. (B–E) Developing leaves for various genotypes. (B) A normal leaf from Col. (C) A leaf from gl1 showing the absence of trichomes on the leaf surface but with a similar shape as Col. (D) A serrated leaf from CA1 that has a narrow shape but contains trichomes. (E) A leaf from the CA1; gl1plant that exhibits phenotypes of both gl1 and CA1. (F) Fastening the plant on the microscope base by the tape (indicated by the arrow). (G–H) Removing siliques, flowers, and young flower buds. (I–K) Removing anthers. (L) A damaged pistil (indicated by the arrow). (M–O) Pollinating the stigma. (P) A pollinated stigma. (Q) Labeling the cross.
