RT-PCR transcript analysis to detect gene expression in developing seeds (A) prior to and during flowering (B) and in roots from 9-d-old seedlings (C). The housekeeping gene EF1-α was used as the control for mRNA amounts between the samples. A, Developing seeds at different DAP, as indicated. WT, Wild type. B, 12L and 14L indicate leaves (and shoot meristem tissues) from 12-d-old and 14-d-old seedlings, respectively, and FB indicates flower bud. C, T indicates transgenic CnAIP2 plants and W indicates wild-type (Col-0) plants.
