Schematic diagrams of the structures of Esi47 and its Arabidopsis homologous genes. □, Untranslated exons; ▪, protein kinase ORFs; ▨, uORFs; boxes with dotted lines, hypothetical 5′-UTRs for which no cDNA sequence is available; inverted “V,” introns. For the EST clone representation, solid thick lines represent sequenced parts of cDNA insert of EST clone; dashed thick lines represent unsequenced parts of cDNA. The chromosomes on which the Arabidopsis genes are located are indicated in brackets. The introns of Esi47 are numbered as I-1, I-2, I-3, and I-4. Introns of the Arabidopsis genes shown in the region not confirmed by cDNA sequences are predicted by gene annotation as provided in the GenBank entries. The regions are not drawn to scale.
