Wheat amino acid transporters highly expressed in grain cells regulate amino acid accumulation in grain

Localization of TaAAP2B, TaAAP13D, and TaAAP21A by promoter::GUS expression.
The GUS expression patterns driven by promoters of TaAAP2B, TaAAP13D, and TaAAP21A in T2 developing grains at 7, 14, 21, 28 and 33DPA (days post anthesis). The GUS staining was visualised directly for TaAAP2B and TaAAP13D or after serial ethanol de-staining for TaAAP21A under stereomicroscope Leica MA250. Scale bars represent 500 μm except TaAAP2B (21D enlarged) and TaAAP13D (7D) for 250 μm. ETC: endosperm transfer cells, EM: embryo, AL: aleurone cells, ES: epithelium of scutellum, SE: starchy endosperm, RP: root primordia.
