Figure 3.
Structure of the QRT3 locus At4G20050. The regions of the primary transcript present in a putative full-length cDNA are shown as boxes. The 5′ and 3′ non-translated regions are shown as gray boxes. The primary transcript is processed to remove three introns, one of which is in the 5′-non-translated region. The site of insertion of the TDNA inserts corresponding to the qrt3-1 and qrt3-3 mutations are indicated below the figure.
