Expression ofPtoPIP1;1and flowering-related genes in WT and twoPtoPIP1;1OEArabidopsislines (OE-1 and OE-5).aThe expression ofPtoPIP1;1.b-eThe expression levels of four flowering time pathway-related genes.fThe expression levels of major hub genes in the regulatory networks underlying floral timing. The 14-DAS plants after 8 h of light (n = 3) were measured, andActin2was used as the internal control. Data were analyzed statistically using Student’st-test. *P < 0.05. **P < 0.01. PIP (plasma membrane intrinsic protein); VRN (vernalization response); CRY (cryptochrome); GAI (gibberellin-insensitive); RGA (repressor of GA1-3); SPY (spindly); FCA (an RNA-binding protein); FPA (an RNA-binding protein); FVE (a WD-40 repeat protein); AP1 (apetala1); FT (flowering locus t); FD (flowering locus d); SOC (suppressor of overexpression of constans 1); LFY (leafy); CO (constans); FLC (flowering locus c)
