Appearance of albino tissues in three independent transgenic lines. A, T2 progenies of transgenic lines no. 3, 8 and 57. 24-day-old seedlings grown under 12/12 hr photoperiod at 110 μmol.m2.sec-1 and 22°C are shown. B, Some rosette leaves (1st vegetative leaf is shown on the left) from wild type (WT) and variegated lines no. 3 (3A), no. 8 (8A) and no. 57 (57A) T3 plants grown for 5 weeks are shown. C, Variation of the first vegetative leaf that developed albino tissues in the three transgenic lines. At least 40 plants developing albino tissues from each transgenic line were recorded and analyzed. Non-leaf indicates count for the variegated phenotype that appeared only in inflorescence tissues.
