Microarray based expression analysis of Dicer-like, Argonaute and RDR genes of rice and Arabidopsis. For rice genes the expression profiles have been analyzed in vegetative tissues (Y leaf, mature leaf, roots), Shoot Apical Meristem (SAM) and six stages of panicle development (P1 to P6) along with 3 substages of P1 i.e. P1-I, P1-II and P1-III, five stages of seed development (S1 to S5) and under three abiotic stress conditions (cold, salt and dehydration). For Arabidopsis, expression profiles of two vegetative stages (leaf and root), five stages of flower development (F1–F5), five stages of silique development and three stress treatments (cold, salt and dehydration) have been compiled. The color bar in each panel represents log2 expression values. Developmental stages used for expression profiling are mentioned on top of each column. Panicle and seed stages have been listed in the temporal order of development. On the left side of expression map, cluster dendrogram is shown. The bar graph in panel B shows the expression profiles of OsAGO15 based on MPSS data [41] from 60-days mature leaf, 60-days mature root, 60-days crown meristematic tissue (NME), 90-days immature panicle (NIP), mature reproductive organs (MRO) and 3-days germinating seed (NGS). Expression of OsAGO2 that shows two-fold up-regulation in response to all three stresses is boxed in blue in panel B.
