Fig. 6. Functional characterization of MdTMT1 by overexpression in the Arabidopsis TMT1 mutant (tmt1). Significance tests are labeled i, ii, iii, and iv. Different letters above columns denote significant differences (P < 0.01).
a Forty-day-old plants of wild-type Arabidopsis (WT), TMT1 mutant (tmt1) and tmt1 overexpressing MdTMT1 (tmt1 mutant+MdTMT1). b Contents of sucrose, glucose, and fructose in the above three Arabidopsis lines.
