The expression level of four genes from SL biosynthesis pathway in shoot bases in phosphorus starvation experiment by qRT-PCR. D27, DWARF27; CCD7, 9-cis-beta-carotene 9′,10′-cleaving dioxygenase; CCD8, carlactone synthase; MAX1, more axillary branching1. “*” indicates that P-value < 0.05. GAPDH was used as the housekeeping gene
