Figure 3.

Nucleotide sequence of GA3. The nucleotide sequence of the GA3 gene from the L.er ecotype of Arabidopsis is shown with the sequence of the L.er cDNA clone underlined. The predicted amino acid sequence is shown under the nucleotide sequence. The sequence of the eight oligonucleotide primers used in the sequencing of the ga3 mutant alleles is shown italicized with the direction indicated by < or >. The nucleotide changes in the ga3-1 and ga3-2 mutants are shown above the sequence with the changed nucleotide underlined. The alternatively spliced region 3′ of intron 6 is shown italicized and indicated above the sequence. Putative TATA boxes are shown underlined at bases 438 and 535. Nucleotides are numbered on the left, amino acids on the right.
