Analysis of PtrA/NINV mRNA abundance, A/N-INV activity, and sugar levels. a-d Transcript levels of PtrA/NINV (a), A/N-INV activity (b), sucrose levels (c) and reducing sugar contents (d) in the transgenic lines and WT under normal growth conditions and under cold and salt stress (n = 3). Statistically significant differences between the transgenic lines and WT grown under the same conditions are shown (*P < 0.05, **P < 0.01, ***P < 0.001)
