The temporal and spatial patterns of anthocyanin pigmentation in the maize plant are determined by the presence or absence of the R protein product, a presumed transcriptional activator. At least 50 unique patterns of pigmentation, conditioned by members of the R gene family, have been described. In this study, microprojectiles were used to introduce into maize cells a vector containing the transcription unit from one of these genes (Lc) fused to a constitutive promoter. This chimeric gene… CONTINUE READING
