The effect of M3 or 3m1 mutation on PIN2 trafficking and PIN2-mediated root gravitropism. (A) Representative confocal images of the root epidermal cells of homozygous pin2 complemented with PIN2 (ProPIN2:PIN2:GFP), M3PIN2 (ProPIN2:M3PIN2:GFP), and 3m1PIN2 (ProPIN2:PIN2:GFP). Bar = 5 μm. (B) Relative degrees of root gravitropism of wild-type (WT), homozygous pin2, and homozygous pin2 complemented with PIN2, M3PIN2, and 3m1PIN2 after 24-h gravitropic stimulation (n = 44–135 seedlings).
