Histochemical analyses of SLAH3 and SnRK1.1. Different developmental stages and different tissues of transgenic plants harboring pSLAH3::GUS or pSnRK1.1::GUS were collected and stained. A and H, One-day-old seedlings (scale = 1 mm). B and I, Four-day-old seedlings (scale = 5 mm). C and J, The roots of 4-d-old seedlings (scale = 0.1 mm). D and K, The root tips of 4-d-old seedlings (scale = 0.2 mm). E and L, The cotyledons of 4-d-old seedlings (scale = 0.5 mm). F and M, The inflorescences of 5-week-old plants (scale = 5 mm). G and N, The carpels of 5-week-old plants (scale = 1 mm).
