To elucidate the resistance mechanism of exogenous trehalose on water deficit further, we investigated the effect of exogenous trehalose (50 mM) in wheat callus during water deficit and subsequent recovery. Enhanced levels of endogenous trehalose were detected in calli exposed to water deficit (W) and trehalose (T) medium, moreover, W plus T treatment(More)
