Fig. 1: Overexpression of MdATG8i promotes growth and water use efficiency (WUE) in apple plants under long-term moderate drought conditions.

From: Overexpression of MdATG8i improves water use efficiency in transgenic apple by modulating photosynthesis, osmotic balance, and autophagic activity under moderate water deficit

Water was withheld to maintain the soil at 45–50% field capacity from June 20, 2018 to September 8, 2018. a Growth phenotypes of WT plants and MdATG8i-overexpressing apple lines after 80 days of growth under normal or moderate drought stress conditions. Comparisons of plant height (b), trunk diameter (c), total fresh weight (d), total dry weight (e), relative growth rate (RGR; f), relative water content (RWC; g), instantaneous water use efficiency (WUEI; h), and long-term water use efficiency (WUEL; i) between WT and transgenic plants under 80 days of normal or moderate drought stress conditions. The data are shown as the means of six replicates with SDs. Values with different letters differed significantly at P < 0.05 according to Tukey’s multiple range test.
