Fig. 5. Quantitative real-time RT-PCR data of transcript abundance (relative to the level of ns2 transcript in vegetative apices and normalized to ubiquitin transcript levels) in maize tissues employing primers specific for ns1 or ns2 transcripts (see Materials and methods). ns transcripts accumulate in tissues enriched for vegetative shoot meristems and inflorescence meristems (apices, ears and tassels), but are not detected in mature lateral organs (coleoptile, juvenile leaves) or roots.
