stt3a-1 and stt3a-2 Alleles Contain T-DNA Insertions in Different STT3a Exons.
Scheme illustrates the location of the T-DNA insertions in STT3a (At5g19690) of the independent alleles. Exons (closed boxes) were deduced from the cDNA sequence, and open boxes indicate the 5′ and 3′ untranslated regions. Open triangles indicate T-DNA insertion sites, and the orientation of the T-DNA left border (LB) is indicated. stt3a-1 and stt3a-2 alleles contain T-DNA insertions in the 18th and 15th exons, respectively.
