Expression of ZmABI4 and VP1 during Seed Development.
(A) Expression of ZmABI4 in vegetative tissues and during early kernel development. RT-PCR analysis of ZmABI4 expression in leaf (L), root (R), tassel (T), and kernel tissue collected at 5, 7, 10, and 15 DAP.
(B) Transcript accumulation in kernel tissue collected throughout seed development (from 5 to 30 DAP) was measured by RT-PCR. Actin expression was included as a constitutive control.
