Table II. Characteristics of trehalase-modified plants after 20 d of water restriction, followed by a recovery period of 48 h upon rewatering.
The number of surviving plants out of five individuals, fresh weights of the surviving plants, dry weights of all the plants, and the number of newly appeared leaves in Ler plants are listed. Values are averages ± sd (n = 2–5). Significant differences are as indicated: *P < 0.075, **P < 0.05, ***P < 0.01 (Student’s t test; n = 5). NA, Not applicable (see text); ND, not determined.
