Total RNA and small RNA were prepared from petals at the three following developmental stages: Non-colored petals early during development (Closed bud; Stage 1); Petals at onset of anthocyanin synthesis (Closed bud; Stage 2); Fully colored petals with maximum anthocyanin content (Bud opening; Stage 3). Total RNA was prepared as previously described69 (link). One microgram of RNA was used in reverse transcription assay and qPCR as previously described70 (link) using gene specific primers (Supplementary Notes 10; Supplementary Tables 8 and 9 ). Small RNAs were extracted using Macherey-Nagel NucleoSpin® miRNA. Contaminating DNA was removed using the Ambion® DNA-free kit (Cambridgeshire, UK). RNA concentration was measured on a NanoDrop ND-1000 Micro-Volume (NanoDrop Technologies) before and after DNase treatment. Small RNA quantification was performed using stem-loop RT-PCR as previously described71 . Reverse transcription was performed with RevertAid kit (Thermo Fisher Scientific). Primers specific to 5.8S rRNA or stem-loop RT-primer for miR156 (Supplementary Notes 10; Supplementary Table 8 ) were used. 5.8S rRNA and miR156 expression were quantified on QuantStudio™ 6 Flex Real-Time PCR 384 (Applied Biosystems) using Fast SYBR® Green Master Mix kit (Roche Diagnostic) and specific primers (Supplementary Notes 10 ). Data were collected for three independent biological replicates.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
