Expression of GRCD2 in various Gerbera tissues. (Right) Total RNA from different Gerbera organs, pooled from several developmental stages, was hybridized with GRCD2 full-length probe. The GRCD2 gene is expressed in all floral organs {pappus [i.e., sepals (14)], petals, stamens, and carpels} and other floral tissues, including ovary, bracts, scape, and receptacle. Expression was also detected in young capitula, suggesting that the GRCD2 gene is also active during early stages of inflorescence and flower development. Very weak expression was detected in the leaf blade, but there was no detectable expression in leaf petioles or roots. (Left) Equal loading of RNA was controlled with ethidium bromide staining (18S rRNA).
