Differential expression of genes involved in cytokinin action between panicles and vegetative tissues.

The average gene expression value during early panicle development was compared to that found in rice roots and shoots following treatment for 2 h with 5 μM BA or a vehicle control [13]. Representative genes exhibiting significant differential expression in panicles compared to vegetative tissues are shown (ANOVA with Holm post-test, * p < 0.05, ** p < 0.01).
