Expression

Organism Comment Expression
Solanum lycopersicum exposure of tomato roots to 0.01 mM aluminium (Al), for 1 h increases the mRNA accumulation of isoform LHA1. The activity of the enzyme reaches a maximum in the roots exposed to 0.01 mM Al, and higher Al concentrations results in a decline of the activity, although it is still stimulated by 0.05 mM Al when compared with the control roots. The regulation of plasma membrane H+-ATPase in response to Al is subjected to transcriptional and posttranscriptional control. Exposure of tomato roots to 0.01 mM LaCl3 for 1 h also causes a significant increase in enzymatic activity up
