Phenotypes of TaSK1.2-1 and TaSK2.2-1 Arabidopsis transgenic lines. a, d 26 and 22 days old wild type Columbia plants. b, c 28 and 66 days old TaSK1.2-1.P4T23 line. The 28 days old plant had leaves with thin blades. After 66 days, the plant with a reduced apical dominance had reached a size of 11 cm while wild type plants had a size of at least 40 cm. e, f 22 and 57 days old TaSK1.2-1.P6T26 line. After 57 days, the plant reached a size of 6 cm whereas wild type plants had a size of 40 cm. g 43 days old TaSK1.2-1.P3T4 severe dwarf line. h 43 days old TaSK2.2-1.P2T2 severe dwarf developing flowers. i, j 43 and 60 days old TaSK1.2-1.P3T1 dwarf line showing leaves with thin blades, and later flowers. k, l 43 and 60 days old TaSK1.2-1.P3T6 severe dwarf differentiating flowers. Bars in (a), (b), (d), (e) represent 5 mm while bars in (g) to (l) represent 1 mm
