Induction and Regulation of Heat-Shock Gene Expression by an Amino Acid Analog in Soybean Seedlings.

abstract：:Regulation of apoplastic NH4+ concentration in leaves of oilseed rape (Brassica napus L.) was studied using a vacuum-infiltration technique that allowed controlled manipulations of the apoplastic solution. In leaves infiltrated with NH4+-free solution, the apoplastic NH4+ concentration returned in less than 1.5 min to...
