Fig. 1.

Overexpression of PtrABF in trifoliate orange confers enhanced dehydration tolerance. (a) Phenotypes of leaves detached from 60-day-old transgenic lines (#8 and #10) and the wild type (WT) before and after 90min of dehydration treatment under an ambient environment. (b) Rates of water loss from the detached leaves of the WT and transgenic lines during the dehydration treatment, measured every 15min. Error bars indicate the SD (n=3). (c, d) Electrolyte leakage (c) and cell death (d) in the WT and transgenic lines measured after dehydration stress. Error bars indicate the SD (n=3). Asterisks indicate a significant difference between the WT and transgenic lines (***P<0.001). (This figure is available in colour at JXB online.)
