The main purpose of this project is to identify genes that are required for maize shoot apical meristem (SAM) function and leaf primordia development through microarray analysis and gene annotation. Information about all genes is readily available and searchable at sam.truman.edu. The database can be analyzed in many ways to assist our understanding of the genetic circuitry of the SAM. We found an up regulation of SUMO in the SAM compared to the whole seedling. Sum, a ubiquitin like protein has been shown to be involved in several key developmental process including flowering time in plants through its implication in the ABA signaling pathway. Analysis for the conserved SUMO domain and comparison to all four biologically expressed A.thaliana SUMO proteins, reveals the presence of a potential SUMO protein in our database. Unlike in A.thaliana however, only one SUMO seems to be differentially regulated in the SAM versus whole seedling.
