Expression Patterns of UGT74F2, UGT76C4, and UGT76C5 in Arabidopsis Tissues.

(A) qRT-PCR analysis of UGT74F2, UGT76C4, and UGT76C5 transcript levels in different tissues. Error bars represent the sd of three independent experiments.

(B) Histochemical GUS staining of Pro_74F2:GUS, Pro_76C4:GUS, and Pro_76C5:GUS transgenic plants. All seed tissues had been stained for 4 h except the dissected seed (intact dry seeds had been stained in GUS solution for 48 h before dissection). Stratified seed means the seeds were stained after a 2-d stratification (4°C). Germinated seed means the seeds were stained after a 2-d stratification (4°C) and 1-d germination (22°C). Bar = 0.1 mm.
