Figure 1

Gene structures and genomic arrangement of the 13 Meg genes in maize. ( A ) Meg genes and their flanking regions are aligned to illustrate their gene structures. Promoters and exons of Meg genes are depicted as red and blue rectangles, respectively. Note that Meg14 is missing the canonical Meg promoter. Each superfamily of transposons is shown as a rectangle with the following color codes: xillon-digus - yellow, prem1 - orange, ji - brown. The transposon insertions within 10 kb upstream and 5 kb downstream of each gene model are shown. All of the Meg genes except Meg1, Meg13 and Meg14 have xillon-digus on their 5’ side and CACTA sequences on their 3’ side (asterisks). Two putative H-type thioredoxins downstream of Meg14 and SbMeg2 are colored light blue. All other regions are colored gray. All components of the region were drawn to scale according to their physical sizes. ( B ) The 800 kb region in chromosome 7S that contains the 13 Meg genes is detailed. Color codes for the 6 main elements in the region are provided under the diagram.
