Drought tolerance assays. (a) “Matterhorn” plants before drought induction; (b) after 21 days of continuous water withholding; (c) “Matterhorn” drought recovered plants after water reapplication; 1: control non-transgenic plant that was watered throughout the experiment; 2: “Matterhorn” transgenic plant after 21 days of no-irrigation, 3: wild-type non-transgenic plant after 21 days of no-irrigation; (d) root growth in plants after 21 days of drought stress. 1: Control non-transgenic plant roots; these were watered daily, 2: transgenic plant roots after 21 days of no-irrigation, and 3: wild-type non-transgenic plant roots after 21 days of no-irrigation.
