rglg1 rglg2 Mutant Plants Misexpress Genes of the Apical Meristem.
Apical meristem regions of 24-d-old plantlets were used for RNA preparation, reverse transcription, and real-time PCR quantification. rglg1 rglg2 double mutant plants contain approximately four times more WUS transcript, approximately three times as much CLV3 transcript, and approximately half the amount of STM mRNA, whereas other gene expression profiles, such as those of CLV1, CLV2, and cycD3, remain unchanged.
