LncRNAs are developmentally and physiologically regulated. a Heat maps showing the abundances of differentially expressed lncRNAs in different plant tissues and in plants treated with ABA, drought or cold. Rows are ordered based on a k-means clustering of lncRNAs. Color intensity represents the fractional density across the row of FPKM counts. b–d Detection of representative lncRNAs in the indicated samples by RT-qPCR. Error bars represent s.e.m (n = 3), asterisks indicate a significant difference (t-test, P-value < 0.05). Source data are provided as a Source Data file
