Gene structures of TaMET1 genes. A) The two MET1 genes from rice (OsMET1a; [GenBank: Os03g58400] and OsMET1b; [GenBank: Os07g08500]) were used as a reference to define two MET1 lineages (hereafter called MET-1a and MET-1b lineages). OsMET1a and OsMET1b are shown at the top of each lineage. Gene structures and splice junctions organize TaMET1 genes in 11 exons (black and grey boxes) and 10 introns (horizontal lines). The three distinct protein domains identified are indicated at the top of the figure: DNMT1-RFD (light grey), BAH-domain (dark grey) and DNA methyltransferase (black). TaMET1 genes from chromosome 2 and 7 as well as chromosome 5B are predicted to yield a full-length MET1 protein while 5A and 5D contain stop codons (*) and deletions (Δ). 5′ and 3′UTRs are indicated as smaller boxes. Potential promoter regions were defined as the ~2-3 kb region upstream of the coding sequences and are indicated as a thicker blue line. Unknown sequence insertion (TaMET-7D1) is indicated as a red line and transposable element insertion of Stowaway, Gypsy, Mariner and Mutator are indicated as red boxes. B) Methods used in this study.
