Structure and expression of AAO3 and aao3. (A) Structure of the AAO3 gene and location of the mutation at the end of the ninth intron. Arrows indicate the position where primers for RT-PCR were designed. WT, wild type. (B) RT-PCR fragments obtained from cDNAs synthesized from total RNA prepared from rosette leaves using primers represented in A. (C) Illustration of RT-PCR fragments detected in wild type and aao3.
