Abstract
Cell elongation is essential for plant morphogenesis. Recently, several genes related to the process have been identified using molecular genetics. However, the comprehensive information of gene expression and regulation during the process are poorly understood. In this study, we examined oligomicroarray analysis to get comprehensive information about the gene expression profiles during cell elongation in A. thaliana.
For microarray experiments, RNA samples were prepared from wild type and cellulose deficient mutants and were used as templates for Cy3- or Cy5-labeled cRNA synthesis. We used the Agilent Arabidopsis 2 Oligo Microarray and analyzed the data using computer software 'Luminator' (Rosetta Biosoftware). We have already collected several gene expression profiles in the hypocotyls, the rosettes and the stems. We are currently analyzing the data to identify the genes whose expression is induced during cell elongation in the organs.
