Global gene expression analysis in the shoot apical meristem of maize

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 SAMs (SAMs per se plus P0 and P1) and above-ground portions of seedlings collected from 14-day old B73 seedlings. These RNA samples were labeled and hybridized with cDNA microarrays that have 14,400 informative spots from maize. Statistical analyses showed that approximately 6.3% and 6.5% of the tested genes were significantly (p <0.0001) up- and down-regulated, respectively. Several cont
