Maize inbreds B73 and Mo17 exhibit large differences in gene expression during elongation and secondary wall stages of stem development. Transcript levels in rind tissues of greenhouse-grown plants taken at elongation stages (Internodes 8 and 6) and secondary wall synthesis stages (Internodes 5 and 4) of each inbred were pooled and normalized and compared as counts per 20 M reads. a GT47 Group A xyloglucan galactosyl transferase genes showing relatively common expression. b GT47 Group E xylan xylosyl transferase genes that show the same relative patterns of expression but significant expression fold-differences. c AGP/Fasciclin-like proteins that show unique patterns of expression that result in fold-change differences. d Cinnamyl alcohol dehydrogenase (CAD) genes that show dominant expression of different genes that result in fold-change differences
