Correlation among phenotypical traits and gene expression.

Shoot fresh weight (SFW), root fresh weight (RFW), root to shoot ratio (RSRa), root length (RL), P concentration ([P]), shoot P, P uptake efficiency (PUpE), P use efficiency (PUtE) and physiological use efficiency (PPUE) with the relative expression of the studied genes.aEach data is the Pearson correlation of the studied trait with the normalized value of expression of each gene. In PUpE and PUtE the correlation is calculated with the fold-change of expression of the gene from NoP to control treatment.*,**,***, are significant at Pns non-significant.
