Wheat amino acid transporters highly expressed in grain cells regulate amino acid accumulation in grain
Fig 6
The protein distribution of mature grain resin sections of TaAAP13 overexpression line.
(a), Dorsal of P23-OE. (b), Dorsal of P15-null. (c), Lobe of P23-OE. (d), Lobe of P15-null. (e), Whole grain section of P23-OE. (f), Whole grain section of P15-null. Resin sections with 1 μm thickness in (a)-(d) and 0.5μm thickness in (e) and (f) were stained with 1% (w/v) Naphthol Blue Black in 7% (w/v) acetic acid. Scale bars represent 50 μm in (a)-(d) and 1mm in (e) and (f). Red arrows indicated large protein body matrix (PB). AL: aleurone cells, SA: sub-aleurone cells, SG: starch granules.
