P– regulated lncRNAs were potential targets of PHR1. a Integrated Genome Browser (IGB) visualization of expression level of lncRNA AT5G01595.1 and its antisense gene AtFer1. Both AT5G01595.1 and AtFer1 were induced in roots under P– condition and carried a P1BS motif at their promoter regions. b P1BS motifs were significantly enriched for lncRNAs in clusters 1 and 2. The difference in ratios was tested using χ2: a compared with b, P < 0.01; no significant difference within a and b. All: All lncRNAs (1692) as control. c Correlation of P1BS motif number and fold induction of lncRNAs in roots and shoots. With increased P1BS content, fold induction of lncRNAs induced by Pi starvation also increased. The header numbers in the gray box indicate the P1BS motif number at the promoter regions of lncRNAs. d Validation of PHR1 potential targeted lncRNAs in the phr1 mutant by qRT-PCR. The lncRNAs that PHR1 targeted were less induced/repressed in phr1 mutant
