Global gene expression in the maize shoot apical meristem

ABSTRACT: All above ground organs of higher plants are ultimately derived from specialized organogenic structures called shoot apical meristems (SAMs). It is comprised of pluripotent stem cells, which divide to regenerate themselves as well as to provide cells to form other organs such as leaves and stems. To study global gene expression in maize SAM and very young primordia (P0 and P1), RNA was extracted from both whole SAMs (SAMs, P0 and P1) and whole seedlings (above ground part of seedlings) collected from 14-day old B73 seedlings. These RNA samples were labeled and hybridized with cDNA microarrays that have about 30,000 maize cDNA clones. Statistical analyses showed that approximately 7% and 8% of the tested genes were significantly up-regulated and down-regulated, respectively. Several control
