Rice stem functions in the transportation of water, minerals and organic compounds, and is essential for the yield and quality of rice. We constructed cDNA library for rice stems at the stage of 4-5 leaves, and conducted EST sequencing and bioinformatical analysis for better understanding of gene expression pattern and stem-specific genes. Some highly-expressed genes were isolated in rice stem cDNA library, and nine cDNA probes were used for hybridization with RNA array containing 755 rice bio-phenotypes to...
