From: Genetic analysis of phytoene synthase 1 (Psy1) gene function and regulation in common wheat
Expression levels of Psy1 in developing grains from T3 transgenic lines and non-transformed controls. Gene expression levels were measured by qRT-PCR and normalized to the transcript level of a constitutively expressed β-actin gene in the same sample. Data are presented as means ± standard error from three biological replicates with three technical replicates each. Significant differences (Student’s t test) in transgenic lines compared to the controls are represented by one or two asterisks: * P <0.05, ** P <0.01. CK, non-transformed controls
