Comparative transcriptome analysis of primary roots of Brassica napus seedlings with extremely different primary root lengths using RNA sequencing
The cDNA library was constructed using polyA+ RNA which was isolated from hydroponically grown 4-day-old primary roots of D43, D61, D69 and D72, that were divided into two groups, short group (D43 and D61) and long group (D69 and D72), according to their extremely different primary root lengths (PRLs).
