The purpose of the following photos is to show the similarities and differences between the vegetative phenotypes of sly1 alleles in the Col and Ler backgrounds. Plants were grown in 4 inch pots under fluorescent lamps in a Conviron under a 16 hr day. The three alleles of sly1 form an allelic series with severity increasing as sly1-10 < sly1-2 < sly1-t2. The phenotypes will vary somewhat in different sized pots and under different light levels (taller when light is weak). It is important to notice the differences between sly1-2 in the Ler (shorter) and Col (taller and bushier) backgrounds. It is very important to always write "Col" on tubes to avoid confusing these plants. The sly1-10 mutant is about the same height as the sly1-2 allele in Col. But notice that the sly1-10 Ler has smaller siliques and that the distance between the siliques is shorter (shorter internodes). The sly1-t2 allele is very similar in appearance to sly1-2 (both in Ler). However, the sly1-t2 allele results in a stronger seed dormancy phentoype and carries a Kan resistance gene on the T-DNA insertion in the sly1 gene.
