At-RSH1, 2, and 3 transcript analysis and gene structures. (A) Poly(A) RNA gel blot with leaf RNA isolated from the Arabidopsis Landsberg erecta (Ler) and Columbia (Col-0) ecotypes, hybridized to radiolabeled cDNA sequences corresponding to At-RSH1 and At-RSH2; transcript sizes indicated in kilobases. (B) Intron/exon structures of At-RSH1, 2, and 3. Wide rectangles indicate transcribed regions, and solid rectangles constitute coding sequence. Narrow rectangles indicate 5′ and 3′ sequences, and intron positions are marked by arrowheads.
