Figure 1.

Some morphological traits of the phenotype of sca3 mutants. Images correspond to cotyledons of 7-d-old seedlings (A–D), 21-d-old rosettes (E–H), and third node vegetative leaves (I–L) of the sca3-1 and sca3-2 mutants and their corresponding wild types (Ler and Col-0, respectively). Six-week-old plants (M) grown on soil and details of their siliques (N and O) and inflorescences (P and Q). R, Fifteen-day-old plants vertically grown on agar medium. All plants were homozygous for the mutations shown. Scale bars indicate 1 mm (A–D, H–L, and N–Q), 5 mm (E–G), 10 mm (R), and 25 mm (M).
