Pearson correlation co-efficient (P-) values were calculated for the genes showing high correlations in transcription activities with secondary wall CesA10 (Q6UDF1), CesA11 (Q67BC8), and CesA13 (Q67BC7) genes. Arabidopsis genes (At) that are orthologous to the maize genes are identified in the right hand columns.
