library_construction_protocol: Total RNA extractions from A and J leaves were performed using the RNeasyPlant Mini Kit (Qiagen, Hilden, Germany) and collected into A and J RNA pools. The small RNAs with the adapters were transcribed into cDNA using Super-Script II Reverse Transcriptase (Invitrogen, Shanghai), and then the cDNA products were amplified by polymerase chain reaction (PCR). RNA libraries were prepared for sequencing using standard Illumina protocols
