Cytosolic calcium levels and stress induced y-amino butyrate synthesis in asparagus mesophyll cells

Cholewa, Ewa M. (Brock University, 1995-07-09)

Numerous investigations have demonstrated large increases in y-amino butyrate (GABA) levels in response to a variety of stresses such as touch or cold shock (Wallace et ale 1984) Circumstantial evidence indicating a ...
L-Glutamate uptake, decarboxylation to -aminobutyric acid and GABA efflux in isolated Asparagus sprengeri mesophyll cells

Chung, Induk. (Brock University, 1989-07-09)

Addition of L-glutamate caused alkalinization of the medium surrounding Asparagus spreng.ri mesophyll cells. This suggests a H+/L-glutmate symport uptake system for L-glutamate. However stoichiometries of H+/L-glutamate ...
The production of 4-adminobutyrate in response to treatments reducing cytosolic pH and the regulation of intracellular pH

Crawford, Lesley A. (Brock University, 1993-07-09)

GABA (4-aminobutyrate) is synthesized through the decarboxylation of LGlu- (L-Glu-+ H+ ---> GABA + C02), and compared to many free amino acids is present in high concentrations in plant cells. GABA levels rise rapidly ...
