library_construction_protocol: not provided Total RNA was first treated with RiboMinus™ Plant Kit for RNA-Seq (Invitrogen A10838-08) to remove rRNA, followed by size selection of RNA on a 15% UREA TBE Polyacrylamide gel (Invitrogen, EC6885BOX). Gels containing RNA with size between 15- to 27-nt were kept for small RNA library, while gels containing 28- to ~300-nt RNA were kept for PATH library. After gel elution, library construction for both sRNA and PATH was done using the Illumina TruSeq Small RNA Sample Preparation Kit (RS-200-0012), except that at the final size selection step, PCR products were separated on a 6% TBE Polyacrylamide gel (Invitrogen, EC6265BOX) and selected for the range from 120- to ~1000-bp for PATH library. Gel-eluted PCR products with different TruSeq index sequences were pooled and sent for Illumina sequencing. The mRNA library was constructed using the Illumina TruSeq RNA Sample Preparation Kit (RS-122-2001) according to the standard manual. PATH libraries were sequenced using either paired-end mode with length of read1 being 120-bp and length of read2 being 30-bp (PE120+30), or single-end 100-bp (SE100); while sRNA and mRNA libraries were sequenced with single-end 50-bp (SE50). All sequencing was carried out on HiSeq2500 machines at the Broad Stem Cell Research Center (BSCRC) sequencing core at University of California, Los Angeles.
