SRX2396271 GSM2417017 SRP094568 PRJNA356280 SRS1837406 SAMN06111415 miRNA-Seq TRANSCRIPTOMIC size fractionation Samples were collected in April 2014. Total RNAs of fertile and sterile flowers were extracted using MiniBEST Plant RNA Extraction Kit (Takara, Dalian, Liaoning, China), according to the manufacturer's protocol. RNA libraries were prepared for sequencing using standard Illumina protocols Illumina HiSeq 2000 gds 302417017 GSM2417017 GEO Accession GSM2417017 SRX2396272 GSM2417018 SRP094568 PRJNA356280 SRS1837407 SAMN06111414 miRNA-Seq TRANSCRIPTOMIC size fractionation Samples were collected in April 2014.
