Tolerance to limited supplies of nitrogen and carbon is enhanced by constitutive expression of MdATG8i in transgenic “Orin” apple callus. (A) PCR verification of constitutive expression. Lanes M, molecular marker DL2000; V, positive vector containing pGWB406-MdATG8i plasmid; WT, non-transformed wild-type; and OE-5 through -7, MdATG8i-transgenic callus lines; (B) qRT-PCR analysis of MdATG8i expression in WT and transgenic lines; (C) Morphology of callus after 20 days; (D) Fresh weights of callus after 20 days. Data are means ± SD of three biological replicates. *, ** or *** indicates the statistically significant differences determined by Student's t-tests at P < 0.05, P < 0.01, or P < 0.001, respectively.
