Expression patterns of some tissue-preferred genes in various tissues shown by qRT-PCR analysis. The mRNA relative amount was calculated as described in the section “Methods”. (A) to (I) showed the expression patterns of 9 tissue-preferred genes. The total RNA samples were prepared from a total of 11 tissues at different developmental stages, which were used as templates for qRT-PCR. These tissues were shown as below: 1, two-week old leaves; 2, two-month old leaves; 3, two-week old roots; 4, two-month old roots; 5, 0-5 cm long panicles; 6, 5-10 cm long panicles; 7, more than 10 cm long panicles; 8, opening panicles; 9, flowering panicles; 10, milky seeds; and 11, mature seeds (21 days after pollination).
